TIT1E OF THE INV~NTION
METHOD FOR MANUFACTURING LABEL-CONTINUED SHEET
RACRGROUND OF THE I~VENTqON
Field of the Inven~ion ~-
The present invention relates to a method for manufac~ <
turing a label-continued sheet, and more particularly, to
the method for manufacturing the label-continued sheet in
which labels each having an opening formed at a predeter-
mined position thereof are releasably adhered to a release
base paper in the longitudinal direction thereof with ;~
regular intervals provided therebetween. ~ -
Description o~ the ~rior Arts
In recent years, there is a growing demand for the ~;
development of a method for effectively manufacturing a
labeI-continued sheet in which each labels having an opening
formed therein are releasably adhered to a release base
paper.
According to the conventional method for manufacturing
such a label-continued sheet as described above, the label
" ~ ,
and the release base paper are punched. That is, an opening
is formed on the`releasé base paper as well.
The release base paper is warped. Therefore, it is
difficult to hold the label-continued sheet around a roller.

.
` - 2028~
In releasing labels from the release base paper.to
stick them to articles one by one by an automatic label
sticking apparatus, labels are not appropriately released
from the release base paper when tension is applied to .the
release base paper and the label. As a result, labels are
wrinkled in the vicinity of the opening formed therein. As
such, labels cannot be stuck to articles at a predetermined
position thereof.
The above method for manufacturing the label-continued
sheet is inappropriate for a mass production and expensive.
SUMMARY OF TH~ INVENIION
It is therefore the principal object of ~he present
invention to provide a method for. mass producing a label-
con~inued sheet in which labels each having an opening
formed.therein are adhered to a release base paper effec-
tively and inexpensively.
A method for manufacturing a label-continued sheet
according to ~he present invention comprises the steps of~
forming a laminated sheet by temporarily adhering label base
paper to release base paper with an adhesive layer; forming
,, I " " ! i ~ ~ ! , ! ' .
: a cut line corresponding to the outline of an opening of a
.
predetermined configuration in the label base paper from one
-: principal surface thereof to the other princlpal surface
: thereof; forming the opening in the label base paper by ~
2 - ~ :
,
~' ~
~ 2028~8~
releasing a portion surrounded with the cut line formed on
the label base paper from the laminated sheet n the bounda-
ry between the adhesive layer and the release base paper;
press-cutting the label base paper from one principal
surface thereof to the other principal surface thereof so as
to shape the label base paper into a predetermined configu-
ration; and separating an unnecessary portion of the label
base paper from the label.
According to the present invention, after a cut line
corresponding to the outline of an opening is formed only on
the label base paper, the portion surrounded with the cu~
line is released from a laminated sheet consisting of the
release base paper and the label base paper in such a manner
that the opening is formed only in the label base paper.
; Accordingly, in sticking labels on articles by an
automatic label sticking machine, labels are not wrinkled
-,:
when tension is applied thereto. Therefore, they are not
,; .
warped and can be smoothly stuck to articles.
These objects and other objects, features, aspects and
advantages of the present invention will become apparent
from the following detailed description of the embodiments
i ~ ' ` ~ ! '
of the present invention when taken in connection with the
accompanying drawings.

~ label-continued sheet 10 includes long and narrow
release base paper 12. The back surface of a label 14 is
releasably adhered to one principal surface of the release
base paper 12 with an adhesive layer 18 formed thereon. The
labels 14 are spaced at regular intervals in the longitudi-
nal direction of the label-continued sheet 10. The label 14
has, for example, an elliptical opening 16 formed in approx-
imately the center thereof. The opening 16 may be rectangu-
lar or circular as shown in Figs. 10 and 11, respectively.
The release base paper 12 consists of, for example, a
long and narrow sheet made of such as paper and a synthetic
resin. The release base paper 12 is coated with a release
agent such as silicon to form a release agent layer thereon.
Accordingly, the label 14 is releasably adhered to the
release base paper 12.
A method for manufacturing the label-continued sheet 10
according to the present invention will be described below
based on a representative manufacturing apparatus shown in
Fig. 1.
First, a lon~ belt-like label base paper 14a to be
formed into the label 14 is releasably adhered to one
,, ,1 l ! ' , ` ! ' '
principal surface of the release base paper 12 with the
adhesive layer 18 formed by applying a pressure sensitive
adhesive to the back of the label base paper 14a. Thus, a
laminated sheet 11 is formed. The laminated sheet 11 is
`::
. :
- 6 -
, ~
` - z~
wound around a holding roller 52 of a manufacturing appara-
tus 50 in order to feed it to each manufacturing process of
the label-continued sheet 10.
The manufacturing apparatus S0 inc~udes the holding
roller 52 for holding the laminated sheet 11. One end of
the laminated sheet 11 consisting of the label base paper
14a and re~ease base paper 12 is unrolled and guided to a
cut line forming device 54.
The cut line forming device 54 comprises a die roll 56
provided on the surface thereof and having cutting edges
corresponding to the configuration of the opening 16. The
die roll 56 forms a cut line 16a on the label base paper 14a
from the upper surface to the lower surface thereof. The
configuration of the cut line 16a corresponds to the out-ine
of the opening 16 of a predetermined configuration. The cut
line forming device 54 may be of a flat type die cutter
having cutting edges corresponding to the configuration of
the opening 16.
The laminated sheet 11 including the label base paper
14a having the predetermined cut line 16a formed thereon is
guided to a release plate 58.
The release plate 58 has a function of releasing an
unnecessary portion 17 encircled with the cut line 16a from
the laminated sheet ll including the label base paper 14a
having the cut line 16a formed thereon. The unnecessary
.
~ ~ 7 ~
202~38~ :
portion 17 is released from the laminated sheet 11 in the
boundary between the adhesive layer 18 and the release base
paper 12. The release base paper 12 and the label base
paper 14a having the cut line 16a formed thereon travelling
horizontally along the release plate 58 are folded down and
then, moved downward in the backward direction. Thus, the -
unnecessary portion 17 encircled with the cut line 16a is
released from the laminated sheet 11 consisting of the
release base paper 12 and the label base paper 14a having
the cut line 16a formed thereon. Only the unnecessary
portion 17 encircled with the cut line 16a moves horizontal-
ly due to its rigidity.
The unnecessary portion 17 released from the release
base paper 12 of the laminated sheet 11 by the release plate
- 58 drops to a box 60. That is, in the laminated sheet 11
consisting of the release base paper 12 and the label base
paper 14a, the opening 16 is formed on only the label base r"'
paper 14a.
The laminated sheet 11 including the release base paper
14a having the opening 16 formed thereon is guided to a
press-cutting device 68 through guide rollers 62, 64, and
j ~
66.
The press-cutting device 68 has a function of shaping
the label base paper 14a having the opening 16 formed
th~reon into the predetermined configuration. The press-
~ . ,
~.
---` 202~3 : -
cutting device 68 includes a die roll 70 provided on the
surface thereof and having cutting edges corresponding to
the configuration of the label 14. The laminated sheet 11
including the label base paper 14a shaped into the predeter-
mined configuration is divided into the label portion 14 and
the unnecessary portion 15 by the cut line 15a. Thereafter,
a removing roller 76 winds the unnecessary portion 15 from
the laminated sheet 11 including the label ~ase paper 14a
shaped into the predetermined configuration. On the other
hand, the label 14 is wound around a roller 78.
According to the label-continued sheet 10 thus manufac-
tured, the opening 16 is not formed on the release base
paper 12, but only on the label 14. Unlike the conventional
label continued sheet in which an opening is formed on both
the release base paper and the label, the label-continued
sheet 10 is superior in that even though tension is applied
to the release base paper 12 and the label 14 having the
opening 16 formed thereon, it can be wound around the
winding roller 78 without being wrinkled or displaced.
Accordingly, an automatic label sticking apparatus (not
shown) is capable of correctly peeling the label 14 off the
, .
release base paper 12 and sticking it to an-article at an
appropriate position.thereof.

Another method fo~- man~facturing the label-continued
sheet 10 according to the present invention is described
based on a manufactllring apparatus as shown in Fig. 4. ~; ;
~ irst, a long belt-like label base paper 14a to be
formed into the label 14 is releasably adhered to one
principal surface of the release base paper 12 with the
adhesive layer 18 by applying a pressure sensitive adhesive
to the back of the base label paper 14a. Thus, a laminated
sheet 11 is formed. The laminated sheet is wound around a
holding roller 152 of a manufacturing apparatus 150 in order
to feed it to each manufacturing process of the label-con-
tinued sheet 10.
The manufacturing apparatus 150 includes the holding
roller 152 for holding the laminated sheet 11. One end of
the laminated sheet 11 consisting of the label base paper
14a and release base paper 12 is unrolled and guided to a
cut line forming device 154.
The cut line forming device 154 comprises a die roll
156 provided on the surface thereof and having cutting edges
corresponding to the configuration of the opening 16. The
die roll 156 forms a cut line 16a on the label base paper
14a from the upper surface to the lower surface thereof.
The configuration of the cut line 16a corresponds to the
outline of the opening 16 of a predetermined configuration.
The cut line forming device 154 may be of-a flat type die

cutter having cutting edges corresponding to the configura-
t.ion of the opening 16.
The laminated sheet 11 including the label base paper
14a having the predetermined cut line 16a formed thereon is
guided to a laminating device 158.
A hot-melt adhesive agent is applied to one principal
surface of a long belt-like film sheet 22 consisting of a
synthetic resin and dried to form an adhesive layer 24 on a
sheet 26 for removing an unnecessary portion. The removing
sheet 26 is held by a holding roller 160.
one end of the removing sheet 26 is unrolled and guided
to a laminating device 158 comprising two rollers 158a and
158b.
hn unnecessary portion 17 which is surrounded with the
cut line 16a and peeled off the label base paper 14a is
adhered to the adhesive layer 24 of the removing sheet 26 by
a removing device 162 which will be described later.
;;~ The laminated sheet 11 consisting of the label base
paper 14a and the release base paper 12 and the removing
sheet 26 are guided between the rollers 158a and 1S8b so
that the adhesive layer 24 is laminated on the label base
. j " j ~ 1 ' : , ! ' ~ , ~
paper 14a having the cut line 16a formed thereon. Then, the
rollers 158a and 158b are rotated to laminate the removing
sheet 26 including the adhesive layer 24 on the laminated
sheet 11 including the label base paper 14a.

2~283~3 ~ ~
The laminated material thus formed is guided to the
removing device 162. The removing device 162 has a function
OI adhering the unnecessary portion 17 surrounded with the
cut line 16a formed on the label base paper 14a to the
adhesive layer-24 of the removing sheet 26 so as to peel the
unnecessary portion 17 off the label base paper 14a.
The removing device 162 includes a heat roller 164
having pressing molds 166 formed on the surface thereof.
The configuration of each pressing mold 166 corresponds to
the configuration of the opening 16 of the label 14. The
removing device 162 further includes a roller 168,
positioned below the heat roller 164, for sandwiching the
laminated sheet in cooperation with the heat roller 164.
The unnecessary portion 17 surrounded with the cut line 16a
formed on the label base paper 14a sandwiched between the
pressing molds 166 of the heat roller 164 and the roller 168
is heated under pressure. As a result, the unnecessary
portion-17 is adhered to the adhesive layer 24 of the
removing sheet 26 and peeled off the label base paper 14a.
The unnecessary portion 17 adhered to the adhesive
layer 24 of the removing sheet 26 is wound around a removing
roller 174 through guide rollers 170 and 172.
Accordingly, in the laminated sheet 11 consisting of
the release base paper 12 and the label base paper 14a, the
opening 16 is formed only on the label base paper 14a.

mlhereafter, the laminated sheet 11 including the label
base paper 14a having the opening 16 formed thereon is
guided to a press-cutting device 176.
The press-cutting die 176 has a function of shaping the
label base paper 14a having the opening 16 formed thereon
into the predetermined configuration. The press-cutting die
176 includes a die roll 178 provided on the surface thereof
and having cutting edges corresponding to the configuration
of the label 14. The laminated sheet 11 including the label
base paper 14a shaped into the predetermined configuration
is divided into the label portion 14 and the unnecessary
portion 15 by the cut line 15a. Thereafter, a removing
roller 184 winds, through guide rollers 180 and 182, the
unnecessary portion 15 of the laminated sheet 11 including
the label base paper 14a shaped into the predetermined
configuration. On the other hand, the label-continued sheet
10 is wound around a roller 186.
According to the label-continued sheet 10 thus manufac-
tured, the opening 16 is not formed on the release base
paper 12, but only on the label 14.
Fig. 5 shows a still another example of a manufacturing
'
apparatus for carrying out the manufacturing method accord-
ing to the present invention.
A manufacturing apparatus 200- shown in Fig. 5 differs
~; from the manufacturing apparatus 150 of Fig. 4 in the method

'' .~ ~. ' '
.:
28~83
.
for removing the unnecessary portion 17 surrounded with the
cut line 16a ~ormed on the la~el base paper 14a. Therefore,
the method of the manufacturing apparatus 200 for removing
the unnecessary portion 17 will be described below.
According to the manufacturing apparatus 150 shown in
Fig. 4, the unnecessary portion 17 surrounded with the cut
line 16a corresponding to the opening 16 is peeled off the
label base paper 14a under pressure hy adhering it to the
hot-melt adhesive layer 24 of the removing sheet 26.
According to the manufacturing apparatus 200 shown in Fig.
5, the unnecessary portion 17 is removed from the label base
paper 14a by adhering the unnecessary portion 17 under
pressure to a pressure sensitive adhesive layer.
That is, according to the manufacturing apparatus 200,
the laminated sheet 11 including the label base paper 14a
having the cut line 16a formed thereon is guided to a
removing device 202.
The removing device 202 removes the unnecessary portion
17 surrounded with the cut line 16a formed on the label base
paper 14a from the label base paper 14a by adhering it to a
pressure sensitive adhesive layer 34 of the removing sheet
:: . , , , ( ' ` . ' ! '
36.
The removing device 202 includes a frame 204 vertically
movably supported by a cylinder 206. A pressing member 208
., ~
having a surface corresponding to the configuration of the
14 -
~`` 2028383
opening 16 of the ~.abel 14 is mounted on the. lower surface
of the frame 204 in the center thereof. Therefore, the
pressing member 208 is vertically movable in association
with the ver.tical movement of the frame 204 caused by the
cylinder 206.
The frame 204 is provided with a holding reel 210 on an
upper portion thereof. The holding reel 210 holds the
removing sheet 36 including the pressure sensitive adhesive
layer 34 formed by applying the pressure sensitive adhesive
to one principal surface of a film sheet 32 made of a
synthetic resin and drying it. A silicon release agent is
applied to the other principal surfaoe of the film sheet 32
to form a release adhesive layer thereon. The unnecessary
portion 17 surrounded with the cut line 16a is adhered to
the pressure sensitive adhesive layer 34 of the removing
sheet 36 so as to remove the unnecessary portion 17 from the
label base paper 14a by the removing device 202.
One end of the removing sheet 36 is unrolled and guided
between the pressing member 208 and a support.ing base 214
through a guide roller 212. In this case, the laminated
sheet 11 consisting of the release base paper 12 and the
i `
~ label base paper 14a laminated thereon and the removing
;~ : sheet 36 are guided therebetween so that the pressure
; sensitive adhesive layer 34 is laminated on the label base
paper 14a having the cut line 16a .formed thereon. The

~ .~
~-` ff~8~f~
pressing member 20f8 and the supporting base 214 positioned
below the pressing member 208 sandwich in cooperation with
each other to compress the removing sheet 36 and the unnec-
essary portion 17 surrounded with the cut line 16a formed on
the label base paper 14a of the laminated sheet 11.
That is, the unnecessary portion 17 is pressed against
both the pressing member 208 and the supporting base 214.
As a result, the unnecessary portion 17 encircled with the
cut line 16a is adhered to the pressure sensitive adhesive
layer 34 of the removing sheet 36. Thereafter, the unneces-
sary portion 17 is removed from the label base paper 14a.
The unnecessary portion 17 adhered to the pressure
sensitive adhesive layer 34 is wound around a winding reel
218 through a guide roller 216. -~
The frame 204 is provided with a guide roller 216
positioned alongside the guide roller 212 and the winding
reel 218 positioned alongside the holding reel 210. A weak
rotational force is imparted to a motor not shown. Accord~
ingly, the winding reel 218 is capable of winding the
unnecessary pofrtion 17 adhered to the pressure sensitive
adhesive layer 34 of the removing sheet 36 through the guiffle
roller 216. i'
Accordingly, in the lamfinated sheet ll consisting of
the release base paper 12 and the label base paper 14a, the
opening 16 is formed only on the label base paper 14a.

Thereafter, the laminated sheet 11 inc~uding the label
hase paper 14a having the opening 16 formed thereon is
guided to a press-cutting device 276 so that the label base
paper 14a is shaped into the predetermined configuration.
Then, the unnecessary portion 15 of laminated sheet 11 is
wound around a roller 284. The label-continued sheet 10
thus formed is wound around a winding roller 286.
According to the manufacturing pparatuses shown in
Figs. 4 and 5, after the opening 16 is formed on the label
base paper 14a, the label base paper 14a is shaped into the
predetermined configuration. The label-continued sheet 10
may be formed as follows: That is, after the label base ~i~
paper 14a is press-cut into the configuration of the label ~ -
14, the cut line 16 corresponding to the outline of the
opening 16 is formed on the label 14 at the predetermined
position thereof. Then, the unnecessary portion 17 sur-
rounded with the cut line 16a is removed from the label base
paper 14a by adhering the unnecessary portion 17 to an
;~ adhesive layer so as to form the opening 16.
; A method for manufacturing the label-continued sheet to
be formed according to the above-described manner will be
described below based on a manufacturing apparatus shown in ~-
Fig. 6. ~ ;
According to the apparatus, as shown in Fig. 6, the

- 2028~3
and the label base paper 14a releasably adhered thereto with
the adhesive layer 18 is guided to a press-cutting device
~76. T~e label base paper 14a is press-cut to form a cut
line 15a corresponding to the configuration of the label 14
by means of a die roll 378. Then, the unnecessary portion
15 of the laminated sheet 11 including the label base paper
14a having the cut line 15a formed thereon is wound around a
removing roller 384 through guide rollers 380 and 382.
Then, the laminated sheet 11 consisting of the label base
paper 14a shaped into the predetermined configuration and
the release base paper 12 is guided to a cut line forming
device 354 so that the cut line 16a corresponding to the
outline.of the opening 16 is formed in the label base paper
14a by a die roll 356.
Thereafter, the laminated sheet 11 including the label
base paper 14a is guided to a laminating device 358.
The removing sheet 26 including the heat sensitive
adhesive layer 24 is held around a holding roller 360. One
end of the removing sheet 26 is unrolled and guided to the
laminating device 358 so that it is laminated on the lami-
nated sheet 11 consisting of the label base paper 14a and
the releàse base paper 12.
The laminated material thus formed is guided to a
removing device 362 at which the unnecessary portion 17
surrounded with the cut line 16a formed on the. label base
2 0 2 8 3 8 3 !
paper 14a is compressed between the pressing molds 366 of
the heat roller 364 and a roller 368. As a result, the
unnecessary portion 17 is adhered to the heat sensitive
adhesive agent 24 of the removing sheet 26. Thus, the
unnecessary portion 17 is removed from the label base paper
14a. In this manner, the label-continued sheet 10 including
the label 14 having the opening 16 formed on the release
base paper 12 is manufactured. Then, it is wound around a
winding roller 386.
Another exiample of the method for manufacturing the
label-continued sheet 10 is described below based on a
manufacturing apparatus shown in Fig. 7.
First, a long belt-like label base paper 14a to be
formed into the label 14 is releasably adhered to one
principal surface of the release base paper 12 with the
adhesive layer 18 formed by applying a pressure sensitive
adhesive to the back of the label base paper 14a. Thus, the
laminated sheet 11 is formed. The laminated sheet is wound
,
around a holding roller 452 of a manufacturing apparatus 450
in order to feed it to each manufacturing process of the
, :.
label-continued sheet 10.
The manufacturing apparatus 450 includes the holding
roller 452 for holdlng the laminated sheet 11. One end of
the laminated sheet 11 consisting of the label base paper
202~38~
14a and release base paper 12 is unrolled and guided to .a
cut line forming device 454.
The cut line forming device 454 comprises a die r~ll
456 provided on the.surface thereof and having cutting edges
corresponding to the configuration of the opening 16. The
die roll 4~6 forms a cut line 16a on the label base paper
14a from the upper surface to the lower surface thereof.
The configuration of the cut line 16a corresponds to the
outline of the opening 16 of a predetermined configuration.
The cut line forming device 454 may be of a flat type die
cutter having cutting edges corresponding to the configura~
tion of the opening 16.
The laminated sheet 11 including the label base paper
14a having the predetermined cut line 16a formed thereon is
guided to a removing device 458. The removing device 458 is
provided to remove the unnecessary portion.17 surrounded
with the cut line 16a from the laminated sheet 11 including
the label base paper 14a having the cut line 16a formed
thereon in the boundary between the adhesive layer 18 and
the release base paper 12.
~.
:~ The manufacturing apparatus 458 includes a sucking box
460, of a hollow rectangular solid configuration, serving as
:~a means for sucking the unnecessary portion 17. As shown in
Figs. 8A and 8B, three elIiptical sucking openings 462 each
.:~
correspon~ing to the configuration of the opening 16 are
--- 2028383
:,. :.. `
fGrmed on the lower surface of the sucking box 460 in the
widthwise direction thereof with regular intervals provided -
therebetween. The sucking opening 462 may be rectangular as
shown in Fig. BD if the opening 16 is rectangular.
, ~ .
The sucking box 460 is connected, through a pipe 464,
with a negative pressure source Inot shown), for example, a
vacuum pump serving as a negative generating means so as to
generate sucking force cn the l~wer portion of the sucking
box 460 through the sucking openings 462. Therefore,
sucking force sticks the unnecessary portion 17, surrounded
with the cut line 16a formed on the label base paper 14a of
the laminated sheet 11, to the lower portion of the sucking
box 460.
The sucking box 460 contains a pressing member 466
consisting of an elastic material, for example, rubber or
sponge. The pressing member 466 comprises three pressing
portions 468 sectionally elliptical. The area of the
;pressing portions 468 is each smaller than that of the
sucking opening 462. Each of the three pressing portions
468 is positioned in correspondence with each of the three
sucking openings 462. The pressing member 466 is vertically
mova~ly supported by a cylinder 470. As such, as shown in
Fig. 8C, the pressing member 466 presses the unnecessary
portion 17 downward, thus dropping it into a container ~not
shown). As shown in Fig. 8D, each of the three pressing
2~28383
portions 468 may be provlded with three openings each
sectionally circular and corresponding with the configura-
tion of the opening 16. The configuration, number, and ar-
rangement of the pressing portion 468 may be selected as
desired.
Accordingly, in the laminated sheet 11 consisting of
the release base paper 12 and the label base paper 14a, the
opening 16 is formed only on the label base paper 14a.
Thereafter, the laminated sheet 11 including the l~bel
base paper 14a having the opening 16 formed thereon is
guided to a press-cutting device 472.
The press-cutting die 472 has a function of shaping the
label base paper 14a having the opening 16 formed thereon
into the predetermined configuration. The press-cutting die
472 includes a die roll 474 provided on the surface thereof
and having cutting edges corresponding to the configuration
of the label 14. The laminated sheet 11 including the label
base paper 14a shaped into the predetermined configuration
is divided into the label portion 14 and the unnecessary
portion 15 by the cut line 15a. Thereafter, a removing
roller 480 winds the unnecessary portion 15 of the laminated
sheet li including the label base paper 14a shaped into the
:. .
predetermined configuration. On the other hand, the label-
continued sheet 10 is wound around a roller 482.

According to the label-continued sheet 10 thus manufac~
tured, the opening 16 is not formed on the release base
paper 12, but only on the label 14.
According to the manufacturing apparatuses shown in Fig
7, after the opening 16 is formed on the label base paper
14a, the label base paper 14a is shaped into the predeter-
mined configuration. The label-continued sheet 10 may be
formed as follows: That is, after the label base paper 14a
is press-cut into the predetermined configuration, the cut
line 16 corresponding to the outline of the opening 16 is
formed on the label 14 at the predetermined position there-
of. Then, the unnecessary portion 17 surrounded with the
cut line 16a is removed by suction force from the label base
paper 14a by adhering the unnecessary portion 17 to an
adhesive layer so as to form the opening 16. This method is
described below based on a manufacturing apparatus as shown
in Fig. 6.
According to the apparatus, as shown in Fig. 9, a
pressure sensitive adhesive is applied to the release base
paper 12. The label base paper 14a is releasably adhered to
: ,
the release base paper 12 with the adhesive layer 18. Thus,
the lami~ated sheet 11 is formed. Then, the laminated sheet
lI is guided to a press-cutting device 572. The label base
~ paper 14a is press-cut to form a cut line 15a corresponding
i~ ~ to the configuration of the label 14 by means of a die roll

ed sheet 11 including the label base paper 14a having the
cut line 15a formed thereon is wound around a removing
roller 580 through guide rollers 576 and 578. Then, the
laminated sheet 11 consisting of the label base paper 14a
shaped into the predetermined configuration and the release
base paper 12 is guided to a cut line forming de~ice 554 so
that the cut line 16a corresponding to the outline.of the
.opening 16 is formed in the label base paper 14a by a die
roll 556.
Thereafter, similarly to the examples as shown in Fig 7
and 8, the laminated sheet 11 including the label base paper
14a having the cut line 16a formed thereon is guided to the
unnecessary portion 17 surrounded with the cut line 16a is
guided to a sucking box 560 and a removing device 558
including a pipe 564 so that the unnecessary portion 17
surrounded with the cut line 16a is stuck by suction force

~ from the label base paper 14a. Thus, the opening 16 is : ::

formed. The label-continued sheet 10 thus formed is wound
