TITLE OF THE INVENIION
METHOD FOR MANUF~C~JRING I.ABEL-CONTINUED SHEET
BACKGROUND OF TH~ INVENTION
Field of the Invention
The present invention relates to a method for manufac-
turing a label-continued sheet, and more particularly, to a
method for manufacturing- a label-continued sheet, having
labels continuously releasably adhered thereto and spaced at
regular intervals in the longitudinal directlon thereof,
suitable for being used by a label sticking apparatus which
automatically feeds the above sheet and peels the label off
a release sheet so as to stick the label to goods.
Description of the Prior Arts
Fig. 5 is a schematic illustration showing an example
of a method for manufacturing a conventional label-continued
sheet. Fig. 6 is a schematic illustration showing an
example of a label-continued sheet manufactured by the
conventional manufacturing method shown in Fig. 5.
When a label 1 is releasably adhered to a long and
narrow release sheet 3 through an adhesive layer 2 formed on
the back thereof, a label base paper is punched to a re-
quired configuration by a stamping device 4, for example, a
cutting die comprising a roller. The unnecessary portion 5
of the stamped label base paper having stamp-out impressions
is wound around a roller 6. Only the necessary portion,
~. A ,
namely, the label 1 is remporarily adhered to the release
sheet 3. A label-continued sheet thus manufactured is wound
around a rollex 7 so that the label-continued sheet can be
mounted on an automatic label sticking device ~not shown). .. .
However, in the label-continued sheet manufactured by
the above described conventional label manufacturing method,
slits 8 formed by the punching device 4 penetrate into the
release sheet 3. That is, as shown in Fig. 5, stamp-out
impressions 9 are formed in the release sheet 3. ~
Accordingly, when the conventional label-continued ~.
sheet is used by mounting it on an automatic sticking
machine (not shown) which automatically sticks the labels 1
to goods by releasing them one by one from the release sheet
3, it may occur that the label lS not normally released from ;~:
the release sheet 3 and to make the matter worse, the
release sheet 3 corresponding to the stamp-out impressions 9
is torn by tensile force applied thereto.

SUMMARY OF THE INVENIION
It is therefore the principal object of the present
invention to provide a method for manufacturing a label-con-
tinued sheet which allows a label to be released from a
release sheet without the release sheet being torn.
According to the present invention, a method for
manufacturing a label-continued sheet having a plurality of
- 2 - -
... . .
labels of certain configuration continuously temporarily
adhered to one principal surface thereof with an adhesive
comprises the steps of: cutting up a label base sheet into
labels of a predetermined configuration before the label
base sheet is temporarily adhered to the release sheet;
shaping said adhesive into ~ predetermined configuration
corresponding to that of the label before the label is
releasably adhered to the release sheet with the adhesive;
and laminating the label and the adhesive with each other
and temporarily adhering the label to said release sheet
through the adhesive.
According to the present invention, since a label is
shaped by cutting up a label base sheet into labels of a
predetermined configuration and the labels are then tempo-
rarily adhered to a release sheet, the release sheet has no
punched marks. Accordingly, when the label-continued sheet
thus manufactured can be used, for example, ~y mounting it
on an automatic label sticking machine, the release sheet is
not torn.
These objects and other objects, features, aspects and
advantages of the present invention will become apparent
from the following detailed description of the embodiments
of the present invention when taken in connection with the
accompanying drawings.

D~SCRlPTION OF THE PR8F~REED EMBODIMENTS
Fig. 1 is a schematic illustration showing an example
of a manufacturing apparatus for embodying the manufacturing
method according to the present invention. Fig. 2 is a
S' ' '' (~ '
sectional schematic illus~ration showing a label~continued
sheet manufactured by the apparatus shown in Fig. 1.
The label-continued sheet 10 includes a release base
paper 12 serving as a long and narrow release sheet. The
back surface of a label 14 is releasably adhered to one
principal surface o~ the release base paper 12 with an
adhesive layer 16. The labels 14 are spaced at regular
intervals in the longitudinal direction of the release base
paper 12. The release base paper 12 includes, for example,
a long and narrow sheet such as paper and a synthetic resin.
The sheet is coated with a release agent such as silicon to
form a release agent layer thereon. Accordingly, the label
14 is temporarily and releasably adhered to the release base
paper 12.
Next, an example of a method for manufacturing the
label-continued sheet lO will be described below based on a
typical manufacturing apparatus shown in Fig. 1.
First, a long and narrow label base paper 14a which is
cut up into labels 14 is wound around a holding roller 52 of
a manufacturing apparatus 50 so that the label base paper
14a can be fed to the process for manufacturing the label-
continued sheet 10.
The apparatus 50 includes the holding roller 52 for
holding the label base paper 14a. The label base paper 14a

i.5 unrolled from one end ihereof and then, fed to a printing
or coating device 54.
The printing or coating device 54, including two
rollers 54a and 54b, coats one principal surface of the
label base paper 14a with an adhesive 16a such as a pressure
sensitive adhesive. The lower portion of the roller 54a is
immersed in an adhesive 16a contained in a pan 54c. There-
~ore, when the label base paper 14a is sandwiched between
the rollers 54a and 54b which are rotating, the label base
paper 14a is coated with the adhesive 16a.
Thereafter, the label base paper 14a is guided, for
example, to a dryer 56 including a heater. The dryer 56
dries the adhesive 16a which coats the label base paper 14a,
so that the adhesive 16a serves as the adhesive layer 16 of
the label base paper 14a. Then, the label base paper 14a is
guided to a cutting device 58. The cutting device 58 cuts
up the label base paper 14a into a plurality of labels 14
each having the same predetermined configuration. The
labels 14 are sequentially guided to a sucking device 60.
The sucking device 60, including a sucking roller 62,
sucks a plurality of labels 14 to hold them. The sucking
roller 62 is connected with a negative pressure source (not
shown) which generates a negative pressure. The peripheral
surface of the sucking roller 62 sucks one principal surface
~unadhesive surface) of the label 14 while the sucking
r ~
f~
~ oller 62 contacts one princ pal surface of the release base
paper 12 in the direction tangential with the peripheral
surface of the sucking roller 62. Thus, sucking roller 62
releasably adheres a plurality of labels 14 to the surface
of the release base paper 12.
The sucking roller 62 has a plurality of sucking
openings ~not shown) formed on the peripheral surface
thereof. A negative pressure can be generated in the
sucking openings by operating the negative pressure source.
Accordingly, when the other principal surfaces (unadhesive
surface) of the plurality of labels 14 approa~h the periph-
eral surface of the sucking roller 62, the sucking roller 62
holds the plurality of labels 14 sucked onto the peripheral
surface thereof by the negative pressure generated on the
peripheral surface thereof.
The release base paper 12 is held around a roller 64.
The release base paper 12 is unrolled from one end thereof,
thus passing a roller 66 and arriving at a roller 68 around
which the release base paper 12 is wound.
The guide roller 66 contacts the peripheral surface of
the sucking roller 62. Therefore, when the release base
paper 12 is guided between the sucking roller 62 and the
guide roller 66, the adhesive layer 16 of the labels 14 held
by the suc~ing roller 62 are sequentially adhered to the
surface of the release base paper 12. Thus, the
- 7 -
lab~l-continued sheet 1~ is formed. Thereafter, the label~
continued sheet 10 is wound around the roller 68. ~;
Owing to the method described above, the release base
paper 12 of the label-continued sheet 10 has no stamp-out
impressions 9 as shown in Fig. 5. Therefore, the label 14
can be released from the release base paper 12 without
tearing the release base paper 12.
Fig. 3 is a schematic illustration showing an example
of a manufacturing apparatus for embodying another manufac- --
turing method according to the present invention.
The label-continued sheet 110 includes a release base
paper 112 serving as a long and narrow release sheet. The
back surface of a label 114 is coated with, ~or example, a
pressure sensitive adhesive so that the label 114 is
I releasably adhered to one principal surface of the release
base paper 112. The labels 114 are spaced at regular inter-
vals in the longitudinal direction of the release base paper
112. The release base paper 112 includes, for example, a
I long and narrow sheet such as paper and a synthetic resin.
Ihe sheet is coated with a release agent such as silicon to
form a release agent layer thereon. Accordingly, the label
114 is temporarily and releasably adhered to the release
base paper 112.
Next, an example of a method for manufacturing the
label-continued sheet 110 will be described below based on a
. .

t ' :~
J r ~
typical manufacturing apparatus shown in Fig. 3. ~;
First, separate labels each having the same predeter-
mined configuration are held by a label holding sec~ion 152
of a manufacturing apparatus 150 so that the labels 114 can
be sequentially fed to the process for manufacturing the
label-continued sheet 110.
The apparatus lsa includes the label hol~ing section
152 for accommodating the labels 114. A sucking device 154
is disposed in the vicinity of the holding section 152.
The apparatus 150, including a sucking roller 156,
sucks a plurality of labels 114 accommodated in the label
holding section 152. The apparatus 150 is connected with a
negative pressure source tnot shown) which generates a
negative pressure. The suckin~ roller 62 has a plurality of
sucking openings (not shown) formed on the peripheral
surface thereof. The negative pressure can be generated in
the sucking openings by operating the negative pressure
source. Thus, the negative pressure generated on the
peripheral surface of the sucking roller 156 allows the
sucking roller 156 to sucX a plurality of labels 114 one by
one accommodated in the label holding section 152.
A printing or coating device 158 is arranged in the
vicinity of the sucking roller 1~6. The label 114 held on
the sucXing roller 156 is coated with an adhesive 116a such
as a pressure sensitive adhesive by the printing or coating

,
device 158 including two rollers 158a and 158b. The roller
158a is arranged so that the peripheral surface thereof
contacts the surface of the label 114 held on the sucking
roller 156. The lower portion of the roller 158a is im-
mersed in an adhesive 116a stored in a pan 158c. According-
ly, when the label 114 passes between the sucking roller 156
and the roller 158a, the label 114 is coated with the
adhesive 116a with the rotations of the rollers 1~8a and
158b.
Thereafter, the label 114 contacts one principal
surface of the release base paper 112 fed in the direction
tangential with the peripheral surface of the roller 156.
Thus, a plurality of labels 114 can be temporarily adhered
to the surface of the release base paper 112.
That is, the release base paper 112 is held by the
roller 160. The release base paper 112 is unfastened from
one end thereof, thus passing the guide roller 162 and
arriving at a roller 164 arou~d which the release base paper
112 is wound. The guide roller 162 is arranged so that it
can contact the peripheral surface of the sucking roller
lS6. Therefore, between the sucking roller 156 and the
guide roller 162, a plurality of the labels 114 held by the
sucking roller 156 are sequentially temporarily adhered to
the sur~ace of the release base paper 112 through the
adhesive 116a. Thus, the label-continued sheet 110 is

manufactured. Then, the label-continued sheet 110 is wound
around the roller 164.
Fig. 4 is a schematic illustration showing an example
of a manufacturing apparatus for embodying the still another
manufacturing method according to the present invention.
A label-continued sheet 210 includes a release base
paper 212 serving as a long and narrow release sheet. The
back surface of a label 214 is releasably adhered to one
principal curface of the release base paper 212 with an
adhesive layer 216. The labels 214 are spaced at regular
intervals in the longitudinal direction of the release base
paper 212. The release base paper 212 includes, for exam-
ple, a long and narrow sheet such as paper and a synthetic
resin. The sheet is coated with a release agent such as
silicon to form a release agent layer thereon. Accordingly,
the label 214 is temporarily and releasably adhered to the
release base paper 212.
Next, an example of a method for manufacturin~ the
label-continued sheet 210 will be described below based on a
typical manufacturing apparatus shown in Fig. 4.
First, label base paper 214a which is cut up into the
labels 214 is wound around a holding roller 252 of a manu~
facturing apparatus 250 so that the label base paper 214a
can be f-ed to the process for manufacturing the label-con-
.. .
tinued sheet 210. ~
'~
,:
The apparatus 250 inclu~es the holding roller 2~2 forholding the label base paper 214a. Th9 label base paper
214a is unrolled from one end thereof and then, fed to a
printing or coating device 254.
The cutting device 254 cuts up the label base paper
214a into a plurality of labels 214 each having the same ~ -
predetermined configuration. The labels 214 are sequential-
ly guided to a sucking device 256.
The sucking device 256, including a sucking roller 25a,
sucks a plurality of labels 214 to hold them. The sucking
roller 258 is connected with a negative pressure source (not
shown) which generates a negative pressure. The sucking
roller 2~8 sucks one principal surface of the label 214
through the peripheral surface thereof. Thus, each time the
sucking roller 258 contacts an adhesive portion of one
principal surface of the release base paper 212 fed forward
from a guide roller 272 in the direction tangential with the
peripheral surface of the sucking roller 258, the sucking
roller 258 temporarily adheres a plurality of the labels 214
to the surface of the release base paper 212.
More specifically, the sucking roller 258 has a pluraL-
ity of sucking openings ~not shown) formed on the peripheral
surface thereof. A negative pressure is generated in the
sucking openings by operating ~he negative pressure source.
Accordingly, when a plurality of labels 214 approach the
- 12 - -
'
i
.y .,i . ~ ~
, f~. fj
peripheral surface of the sucking roller 258 which is
rotating, the negative pressure generated on the peripheral
surface of the sucking roller 258 allows the sucking roller
258 to suck the plurality o~ the labels 214 through one
surface thereof.
The release base paper 212 is held around a roller 260.
The release ~ase paper 212 is unfastened from one end
thereof, thus being guided to a printing or coating device
262.
The printin~ or coating device 262, including two
rollers 264 and 266, coats one principal surface of the
release base paper 212 with an adhesive 216a such as a
pressure sensitive adhesive in such a manner that the adhe~
sive 216a is spaced at regular intervals in the longitudinal
direction of the release base paper 212. There are provided
on the surface of the roller 266 projections 266a spaced at
regular intervals, the configurations of which are identical
to that of the label 214. The lower portion of the roller
266 is immersed in an adhesive 216a stored in a pan 268. ~-~
Accordingly, when the release base paper 212 is guided
between the rollers 264 and 266 which are rotating, the ;~
release base paper 212 is coated with the adhesive 216a at
regular intervals in the longitudinal direction of the ;
release base paper 212. As described above, the
' - ~ .
- - 13 - .; ~
c't~
configuration of portions, of the release base paper 212,
coa.ed with the adhesive 21~a are the same as that of the
label 214.
The release base paper 212 is guided to, for example, a
drier 27~ including a heater. The drier dries the adhesive
216a applied to the release base paper 212 to form the
adhesive layer 216 thereon. The release base paper 212
passes the guide rollers 272 and 274, thus arriving at a
roller 276 around which it is wound.
The guide roller 274 contacts the peripheral surface of
the sucking roller 258. The labels 214 held by the sucking
roller 258 are sequentially supplied to the surface of the
adhesive layer 216 of the release base paper 212 at a
constant speed while the release base paper 212 is fed
forward at a constant speed. Accordingly, each time the
adhesive layer 216 passes between the sucking roller 258 and
the guide roller 274, the labels 214 held by the sucking
roller 258 are sequentially releasably adhered to the
release base paper 212 through the adhesive layer 216. The
label-continued sheet 210 is wound around the roller 276.
Although the present invention has been described and
illustrated in detail, it is clearly understood that the
