PROCESS FOR PREPARING A PAPER REEL FOR FLYING REEL
CHANGE AND APPARATUS FOR CARRYING OUT THE PROCESS
Field of the invention
The invention relates to a method for preparing a paper reel
for flying reel change according to the precharacterizing
clause of Claim l and an apparatus for carrying out the
process, according to the precharcterizing clause of Claim
8. Such processes and apparatuses are used in reel cellars
of printing works.
Prior art
It is known that paper reels can be prepared for flying reel
change by using an adhesive tape which joins the web end
edge to the next lowest layer and at the same time has, on
the outer surface of the paper reel, an adhesive surface for
adhesive bonding to the remainder of the reel (cf. for
example DE-A-43 39 309). Recently, adhesive tapes of this
type have become available (for example, so-called Flying
Splice System 551 from ASS-Etikett GmbH), which consist of
an outer tape and an inner tape which are arranged one on
top of the other and are separably connected. The inner tape
is provided with an inner adhesive surface for joining to
the next lowest layer, while the outer tape has an outer
adhesive surface for joining to the web end and the
remainder of the reel.
It is known that such an adhesive tape can be applied by
first joining it below the web end edge to the next lowest
layer by pressing on the inner adhesive surface and then
~
CA 02303506 2000-03-30
r

pressing the web end edge onto the outer adhesive surface.
This process requires prior determination of the exact
position of the web end edge on the next lowest layer and is
therefore relatively complicated and difficult to automate.
Known processes for applying conventional tapes which avoid
this difficulty by unwinding a web section from the paper
reel, applying the adhesive tape to the web end edge and
then rewinding the paper web and joining the adhesive tape
to the next lowest layer, and corresponding apparatuses (cf.
DE-C-195 40 689), cannot be directly adopted since there the
adhesive tape is applied to the outer surface of the paper
web, which is not possible in the case of adhesive tapes of
the new type. This also applies to other similar cases where
the joint between the web end edge and the next lowest layer
is produced by means of a separate so-called fastening
strip, whereas, for producing the joint with the paper web
of the remainder of the reel, a double-sided adhesive tape
is applied to the outer surface of the paper web, just
before the web end edge (DE-C-39 18 552). Consequently,
adhesive tapes of the new type can at present be applied to
the paper reel only manually in the reel stand or in a
similar holding device.
Summary of the invention
It is the object of the invention to provide a process by
means of which adhesive tapes of the new type described
above can be applied in a simple manner, where possible
fully automatically, to the paper reel. This object is
achieved by the features in the characterizing clause of
Claim 1. It is also intended to provide an apparatus which
is suitable for carrying out the process. This object is
CA 02303506 2000-03-30
r

achieved by the features in the characterizing clause of
Claim 8.
The advantages achieved by the invention are in particular
that the process can be carried out simply and without
visual inspection and is therefore suitable for automation.
Particularly by means of said apparatus, reel preparation
can be carried out very simply and substantially - if
desired also completely - automatically.

Description of the preferred embodiments
A paper reel 1 prepared for the flying reel change in the
reel stand of a printing press comprises a paper web 2,
which is usually wound on a reel core of cardboard. The end
of the paper web 2 forms a web end edge 3 which is, for
example, essentially straight and slightly skew to the
longitudinal direction of the paper web 2. The web end edge
3 is joined to the next lowest layer of the paper web 2 by
CA 02303506 2000-03-30
8
means of an adhesive tape 4 which extends at least
approximately over its total length and also serves for
joining the paper reel to the residual reel.
As is evident from Fig. 3a, b, the adhesive tape 4 consists
of an inner tape 5 and an outer tape 6 which in this case is
slightly narrower, said inner tape and said outer tape
resting one on top of the other and being separably joined.
The join which extends over the total inner surface of the
outer tape 6 is ensured by adhesive bonds at points
distributed over the total said inner surface. The outer
tape 6 may comprise a strip of metal foil, e.g. aluminium
foil, which can be detected by a detector.
The inner surface of the inner tape 5 forms an inner
adhesive surface 7 of the adhesive tape 4 with initial
adhesion in the customary range, which is bonded to the next
lowest layer of the paper web 2, while the outer surface of
the outer tape 6 forms an outer adhesive surface of the
adhesive tape 4 with high initial adhesion, by means of
which an edge strip 8 is bonded, over the total length of
the adhesive tape 4, to a strip of the inner surface of the
paper web 2 which is adjacent to the web end edge 3, so that
said paper web 2 is firmly held by the adhesive tape 4 on
the next lowest layer of the paper web 2. Next to the edge
strip 8, an adhesive strip 9 adjacent to the web end edge 3
and extending parallel to the edge strip 8 over the total
length of the adhesive tape 4 remains free and, during the
flying reel change, serves for joining the paper web 2 to a
paper web 10 (Fig. 3b) which is taken off from a residual
reel.
In the case of the paper reel prepared according to a first
embodiment of the process according to the invention (Fig.
CA 02303506 2000-03-30
9
1), the adhesive tape 4 is interrupted by a short space.
There, the web end edge 3 has a concave space section 11
where the web edge end 3 approximately follows an sine
curve.
In the case of the paper reel prepared according to the
second embodiment of the process according to the invention
(Fig. 2, 4), the adhesive tape 4 extends without
interruption over the total reel width. However, the
adhesive strip 9 is covered by a cover sheet 12, for example
of paper, with a nonadhesive outer surface, in a section
corresponding to the space section 11 in Fig. 1 with respect
to position and extension. However, the cover sheet 12 may
be perforated at points distributed over its surface, so
that an adhesive effect does in fact occur at these points
at high contact pressure.
When the paper web 10 comes to the end, the prepared paper
reel is caused to rotate until the outermost layer of the
paper web 2 has reached a speed which corresponds as exactly
as possible to that of the paper web 10. For this purpose,
the clamped paper reel is accelerated by means of a driven
belt which is pressed against its outer surface. The belt
touches the outer surface of the paper web 2 along an all-
round contact strip 13 (Fig. 1, 2) which crosses the web end
edge 3 in the region of the space section 11 or of the cover
sheet 12 so that adhesion of the adhesive strip 9 to the
belt cannot occur. During this phase, the adhesive tape 4
holds the web end edge 3 firmly on the next lowest layer and
prevents unwinding of the paper web 2.
When the paper reel 1 has reached the required speed, the
paper web 10 is caused to approach it until contact occurs.
As soon as the outer surface of the paper web 10 comes into
CA 02303506 2000-03-30
a
contact with the adhesive strip 9 in the course of the
rotation of the paper reel 1 (Fig. 3b), it is adhesively
bonded to it immediately and carries the outer tape 6 with
it, said outer tape 6 being separated from the inner tape 5.
5 Since it is adhesively bonded by the edge strip 8 to the
outer tape 6, the paper web 2 is likewise carried along.
The paper web 2 and the paper web 10 are thus joined by the
outer tape 6 by virtue of the fact that the inner surface of
the former is adhesively bonded to the edge strip 8 and the
10 inner surface of the latter is adhesively bonded to the
adhesive strip 9 adjacent to said end strip 8, which edge
strip and which adhesive strip together form the outer
adhesive surface. The inner tape 5 remains adhering to the
next lowest layer of the paper web 2. Its outer surface,
like the inner surface of the outer tape 6, no longer
exhibits any adhesive effect, so that there is no danger of
undesired adhesion and consequent web winding.
The paper web 10 is now cut by means of a knife and is
separated from the residual roll. The flying reel change is
thus complete.
The apparatus for preparing the paper reel comprises, in its
basic design (Fig. 5-7), a lifting apparatus 14 having two
cones l5a,b which are displaceable towards one another and
can be introduced into the ends of the core of the paper
reel 1, which is brought, for example on a reel bogie 16, to
the apparatus, and thus serves as a holding apparatus for
the paper reel 1. Arranged above the lifting apparatus 14 is
an unwind table 17 which is horizontal or slopes slightly
downwards at the back and has a conveyor device which
preferably has closed belt-like or string-like conveying
CA 02303506 2000-03-30
11
means 18 which extend in the longitudinal direction, said
unwind table forming a support surface 19 pointing upwards.
A first flap 20 which can be swivelled downwards out of a
horizontal position about a first axis of rotation passing
transversely just below the support surface 19 is mounted at
the rear end of the unwind table 17. Said flap 20 carries a
first adhesion surface 21 which, when the first flap 20 is
in a horizontal position, is in a position of use in which
it points upwards. A second flap 22 can be swivelled back
upwards from a horizontal position about a second axis of
rotation located just above the support surface 19 and
parallel to the first axis of rotation. Said flap 22 carries
a second adhesion surface 23 which, when the second flap 22
is in the horizontal position, is present in a position for
acceptance and use, in which position it points downwards. A
vacuum can be applied to each of the adhesion surfaces 21,
23, up to a point close to their edge. The second flap 22 is
bounded by a slightly skew rear edge which, when both flaps
are in the horizontal position, is above a skew plastics
strip 24 which interrupts the first adhesion surface 21.
Furthermore, the apparatus (Fig. 9a, b) has a cutting
apparatus 25 which is arranged above the rear edge of the
first flap 20. It comprises a transverse rail 26 from which
a short longitudinal rail 27 is suspended so as to be
transversely displaceable, and which longitudinal rail 27 in
turn carries a knife 28 which is pivotable about a
perpendicular axis and has a driven cutting disc 29. The
cutting apparatus 25 can be displaced along a cutting line
(Fig. 10) which essentially follows the rear edge of the
30 second flap 22 and runs over the plastics strip 24.
CA 02303506 2000-03-30
12
Moreover, the apparatus comprises an adhesion apparatus 31
(Fig. l3a,b) which is displaceable by a linear module 32
along the cutting line 30. It comprises a storage roll 33
for holding the adhesive tape 4, whose inner adhesive
surface 7 in this case is still covered by a cover tape 34,
a take-up roll 35 which is arranged adjacent to said storage
roll 33 and is intended for taking up the cover tape 34 and,
between said rolls, a guide roll 36 and a pressure roll 37
retractable from the shown position for use and a pair 38 of
pinch rollers. A tape holder 39 which is slightly
displaceable in the perpendicular direction is arranged
behind the pressure roll 37. In addition, a scissors-like
cutting device 40 which comprises two horizontal blades, a
fixed blade 41 and a blade 42 pivotable about a vertical
axis, is additionally provided approximately at the height
of the pressure roll 37.
Finally, the apparatus (Fig. 16) has a drivable cylinder
brush 43 which is mounted slightly in front of and above the
support surface 19 and whose bristles are produced from
hairs of horses' manes.
The apparatus as described above is suitable for paper reel
preparation according to a first embodiment of the process
according to the invention, as described below:
In the position which is shown in Fig. 7 and in which the
paper reel 1 - it may also have a width other than the 1/1
width shown, the apparatus automatically adjusting to this -
just touches the front edge of the unwind table 17, a web
section 44 is unwound (Fig. 8a, b) by rotating said paper
reel in the direction of the arrow and is transported by the
conveying means 18 towards the rear end of the unwind table
17 so that it extends not only over the total length of the
CA 02303506 2000-03-30
13
support surface 19 but also over the first adhesion surface
21, over the end of which it projects to a greater or lesser
extent. The first flap 20 is in a horizontal position with
the first adhesion surface 21 in a position for use, while
the second flap 22 is swivelled up into a perpendicular
position. The first adhesion surface 21 is then switched on,
i.e. a vacuum is generated at said adhesion surface 21, by
means of which vacuum the inside of the web section 44 is
held firmly against the first adhesion surface 21.
Thereafter (Fig. 9a,b), the cutting apparatus 25 is used and
the knife is moved along the cutting line 30, the cutting
disc 29 being pressed against the plastics strip 24 and
cutting off an end section from the web section 44. The web
end edge 3 (Fig. 10) with the space section 11 is thus
produced. The knife 28 is guided during the cut in such a
way that the axis of the cutting disc 29 is always
perpendicular to the instantaneous cutting direction, i.e.
also while the space section 11 is being produced.
After the end section has been cut off, the second flap 22
is (Fig. lla,b) swivelled into the horizontal position, and
the second adhesion surface 23 is thus brought into a
position for acceptance and use and is switched on, so that,
by means of a vacuum, it firmly holds the outside of that
part of the web section 44 which is adjacent to the web end
edge, the web end edge 3, apart from the space section 11,
exactly coinciding with the rear edge of the second flap 22.
On the other hand, the first adhesion surface 21 is switched
off and the first flap 20 is swivelled downwards (Fig.
l2a,b). The end section which has been cut off falls off.
The adhesion apparatus 31 is (Fig. l3a,b) then used by a
procedure in which, beginning at a lateral edge of the web
CA 02303506 2000-03-30
14
section 44, the edge strip 8 of the outer adhesive surface
of the adhesive tape 4 is pressed by means of the pressure
roll 37 against that strip of the inside of the web section
44 which is adjacent to the web end edge 3, the edge region
of the second adhesion surface 23 serving as a firm support
which prevents said strip of the web section 44 from
deviating, while the remaining part of the outer adhesive
surface, the adhesive strip 9, remains free. While the
adhesion apparatus 31 is moved along the web edge 3,
adhesive tape 4 is unwound from the storage roll 33 and is
applied, as described, to the inside of the web section 44.
At the same time, the cover tape 34 is peeled off from the
adhesive tape 4 on the pressure roll 37 and is wound on the
take-up roll 35, with the result that the inner adhesive
surface 7 of the adhesive tape 4 is exposed.
When the edge of the space section 11 is reached, the
pressure roll 37, which is mounted on a pivotable lever, is
(Fig. l4a,b) retracted while the adhesive tape 4 is pressed
on by the tape holder 39 so that said adhesive tape cannot
become detached again from the web section 44. The cover
tape 34 is taken up so that it remains tensioned. The
pivotable blade 42 of the cutting device 40 is then
swivelled towards the fixed blade 41 thereof and the
adhesive tape 4 is cut between the pressure roll 37 and the
tape holder 39. Finally, that small residual section of the
adhesive tape 4 which is not yet joined to the web section
44 is pressed on by the tape holder 39 while the adhesion
apparatus 31 is moved further until it reaches the edge of
the space section 11. The tape holder 39 is then slightly
lowered.
The adhesion apparatus 31 is then moved up to the opposite
edge of the space section 11. There, the pressure roll 37 is
CA 02303506 2000-03-30
(Fig. l5a,b) brought back to the position for use, and the
adhesive tape 4 is thus again pressed against the web
section 44. With a further supply of the adhesive tape 4,
the adhesion apparatus 31 is now moved, as described further
5 above, up to the lateral edge of the web section 44, where
the adhesive tape 4 is again cut.
Finally, the second adhesion surface 23 is switched off and
(Fig. 16) the web section 44 is withdrawn from the support
surface 19 by rotating the paper reel 1 in the direction of
10 the arrow with corresponding movement of the conveying means
18 and is wound back onto the paper reel 1. The inner
adhesive surface 7 of the adhesive tape 4 is pressed against
the next lowest layer by the action of the cylinder brush 43
rotated in a direction opposite to the direction of rotation
15 of the paper reel 1. Since the inner adhesive surface 7 of
the adhesive tape 4 has initial adhesion only in the
customary range, i.e. does not adhere very rapidly, there is
no danger of adhesion to the support surface 19 on
withdrawing the web section 44. However, with a suitable
design of the cylinder brush 43 - for example as described
further above - no difficulties occur on the outer adhesive
surface either, in spite of its high initial adhesion. The
prepared paper reel 1 can now be stored on the reel bogie 16
by means of the lifting apparatus 14.
If it is intended to prepare the paper reel 1 according to
the second embodiment of the process according to the
invention, it is advantageous to provide additional devices
for automatic application of the cover sheet 12.
Accordingly, a lay-down apparatus 45 is (Fig. l7a,b)
provided and comprises a cover sheet container 46, arranged
adjacent to the unwind table 17 and intended for holding a
stack of cover sheets 12, and a lay-down device 47 having a
CA 02303506 2000-03-30
16
suction plate 48 which is provided with suction cups and can
be moved from the cover sheet container 46 to a cover sheet
holder 49 which is displaceably suspended from the second
flap 22, along the rear edge thereof, for permitting
adjustment to various reel widths. Said cover sheet holder
forms a cover sheet adhesion surface 15 which adjoins the
second adhesion surface 23. On the other hand, the knife 28
need not be pivotable about a perpendicular axis since no
space section is produced and the cutting line is therefore
straight. The suspension of the knife 28 can in certain
circumstances also be simplified in other ways.
In carrying out the process according to the second
embodiment, which otherwise corresponds to the process
according to the first embodiment, after the end section has
been cut off or while it is being cut off, with the second
flap 22 completely swivelled back (Fig. l7a,b), the suction
plate 48 of the lay-down device 47 is moved to the cover
sheet container 46, where it picks up a cover sheet 12. It
is then moved to the cover sheet holder 49, where it places
the cover sheet 12 on the cover sheet adhesion surface 50,
where it is firmly held by means of a vacuum. The
application of the adhesive tape 4 is then effected (Fig.
l8a,b) essentially as described further above. However,
there is no interruption of tape application. At the point
where the cover sheet 12 is subsequently held against the
web end edge 3 on the cover sheet adhesion surface 50, the
adhesive strip 9 is pressed against its underside so that
the cover sheet 12 adheres thereto.
The two embodiments of the process according to the
invention differ only in the manner in which adhesion of the
belt with which the prepared paper reel is brought to the
required speed is prevented. It is of course possible to
CA 02303506 2000-03-30
17
design the apparatus in such a way that this can take place
both in the first manner and in the second manner by both
suspending the knife in a pivotable manner with a view to
producing the space section and providing a lay-down
apparatus and a cover sheet holder.
Also, it is possible to cause the paper reel to rotate by
drivable cones in the reel stand, i.e. without the use of a
belt, in which case the measures described are not required
and the apparatus can be designed in a correspondingly
simpler manner. On the other hand, it is also possible to
provide a plurality of parallel belts for driving the paper
reel, in which case of course a plurality of spacees or
cover sheets must also be provided.
In a modified embodiment of the process according to the
invention, the web section 44 is bent back upwards by about
180° after production of the web end edge 3, and the
adhesive tape 4 is then applied. The application of the
adhesive tape 4 is then effected from above, which
facilitates the procedure, especially if it has to be
carried out manually, for example owing to a fault.
In a modified apparatus adapted to this embodiment of the
process according to the invention, the second flap 22' has
(Fig. 19) a guide surface 51 to which the second adhesion
surface 23 is adjacent. The guide surface 51 has the shape
of a sector of a lateral cylinder surface, whose axis
coincides with the second axis about which the second flap
22' can be swivelled back. The second axis is displaceable
parallel to the support surface 19 and is mounted in such a
way that it moves back over the support surface 19 when the
second flap 22' is swivelled back by the product of the
radius of the guide surface 51 with the angle of rotation in
CA 02303506 2000-03-30
18
radian measure, as if the guide surface 51 rolled on said
support surface 19.
After production of the web end edge 3 by cutting off the
web section 44, which is carried out in the same way as
already described further above, the second flap 22' is
swivelled downwards until the second adhesion surface 23 is
in an acceptance position in which it points downwards (Fig.
20a,b). Thereafter, the first adhesion surface 21 is
switched off and the second adhesion surface 23 is switched
on. The second flap 22' is then swivelled back until the
second adhesion surface 23 assumes a position of use which
is rotated by 180° relative to its acceptance position. That
part of the web section 44 which is adjacent to the web end
edge 3 rests closely, but without tension, around the guide
surface 51, so that no tension is applied to that part of
the web section 44 which rests on the support surface 19 and
to the paper reel.
The application of the adhesive tape 4 is effected (Fig.
2la,b) in principle in exactly the same manner as already
described in detail further above. It is thus possible to
proceed according to both embodiments described. However,
the application of the adhesive tape 4 is effected not from
below but from above. This facilitates monitoring of the
position of the adhesive tape 4. In particular, however, its
application is substantially simpler if it has to be
performed manually, for example because of a failure or a
fault of the adhesion apparatus 31. After application of the
adhesive tape 4, the second flap 22' is always swivelled
back again by 180° so that the second adhesion surface 23
once again assumes its acceptance position. After it has
been switched off, the procedure is continued in the same
CA 02303506 2000-03-30
19
manner as already described further above, and the
preparation of the paper reel is completed.
In addition, some other modifications of the process
according to the invention and of the apparatus according to
the invention are possible. Thus, the web end edge can be
prepared differently to the manner described, for example so
that it is not skew but perpendicular to the longitudinal
direction of the paper web 2. The unwind table may have a
surface of low-friction material, such as, for example,
