DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method for tail-rolling a roll of paper according to the present invention will be described below with reference to an embodiment shown in the drawings. Here, the drawing shows an apparatus that embodies the tail sealing method for a paper roll, an apparatus for adhering a paper edge to a core, and an apparatus for applying a double-sided adhesive tape. Since the present invention should be understood in these whole systems, the present invention describes the method for tail-sealing rolls of a paper roll including the whole system.

FIG. 1 shows a device embodying the method for tail-sealing a paper roll according to the present invention. The tail-sealing device is a web roll (2) in a state in which winding is almost completed.
Is to seal the tail of.

The take-up paper roll (2) is a roll of paper (19) which is placed on a pair of drums (3) and (4) and rotated by being held by a rider roll (7). is there. A touch roll (8) is provided on the drum (3) so as to be able to come into contact with and retract from the drum (3).

The touch roll (8) constitutes a part of a sticking device for a double-sided adhesive tape. The double-sided adhesive tape (10) can be attached to the touch roll (8) in the axial direction of the outer peripheral surface thereof by the tape application unit (9). That is, the touch roll (8) is retracted from the drum (3) while the paper (19) is being wound around the roll (2).

When the winding of the paper (19) approaches the completion, the tape applying unit (9) runs in the axial direction of the outer peripheral surface of the touch roll (8) and applies the double-sided adhesive tapes B and E. On the other hand, a cutter (6) is provided apart from the outer periphery of the drum (3) so as to be able to cut the paper (19) in the axial direction of the drum (3).

The cutter (6) and the push roll (11) outside the cutter (6) are attached to the arm (5) and the drum (3).
It is provided so as to be able to come into contact with and retract from the paper roll (2) at a position separated from the outer circumference of the roll. Next, the take-out path (16) is closely provided on the outer circumference of the other drum (4).

An opening / closing plate (1) in the middle of the take-out path (16)
A core holder (13) attached to the arm (12) is housed below the armature (5). Then roll paper roll (2)
As described above, as shown in FIG. 1, the tapes B and E are attached in the axial direction of the outer peripheral surface of the touch roll (8) when the winding is almost completed.

Next, the touch roll (8) is brought into contact with the drum (3) as shown in FIG. 2 and rotated by being driven. As a result, the double-sided adhesive tapes B and E are attached to the surface of the paper (19) on the outer peripheral surface of the drum (3).

The double-sided adhesive tapes B and E are transferred to the paper (19) because the surface of the touch roll (8) is made of a material such as rubber or synthetic resin having a poorer adhesiveness than the paper. This completes the operation of the double-sided adhesive tape sticking device.

From this point onward, the operation of the tail seal device for the paper roll will be the main focus. That is, the double-sided adhesive tapes B and E travel along with the paper (19) and the drum (3), and come close to the contact point between the drum (3) and the paper roll (2).

Before reaching the contact, the arm (5) advances to the web roll (2) as shown in FIG. 3 and push roll (1).
1) contacts the web roll (2) and pushes it towards the drum (4). As can be seen in FIG. 3, the web roll (2) will be separated from the drum (3).

The cutter (6) is actuated at this separated portion to cut the paper (19) immediately after the double-sided adhesive tape B or at the rear portion thereof. At the same time, the paper presser (18) is the drum (3)
Against this, hold the paper (19) and prevent it from sliding down.

The paper roll (2) is further provided with an arm (5).
The double-sided adhesive tape B passes through the pressing roll (11) while being pressed by the pressing roll (11). As a result, the tail of the paper roll (2) is sealed with the double-sided adhesive tape B.

The sealed paper roll (2) rolls over the take-out path (16) over the drum (4). This completes the operation of the tail seal device for the paper roll.

From here onward, the operation of the device for adhering the paper edge to the core will be the center. That is, when the paper roll (2) rolls from the position shown in FIG. 3 to the position shown in FIG. 4, the opening / closing plate (15) provided in the take-out path (16) is opened.

Next, the core retainer (1
3) will be lifted to feed a new empty core (14) between the drum (3) and the drum (4). That is, the new core (14) is held in the core holder (13) in advance and is inserted between the drum (3) and the drum (4).

A new core (14) is put in, and the drum (3) is reversed as required to put the double-sided adhesive tape E on the core (1).
Paste on 4). As a result, the paper (15) is prevented from slipping down, and at the same time, the paper retainer (18) shown in FIG. 3 retracts.

Next, the arm (12) and the core retainer (1
3) returns to the inside of the opening / closing plate (15) leaving the core (14), and the opening / closing plate (15) is closed as shown in FIG. On the other hand, the rider roll (7) descends again to sandwich the core (14) between the rider roll (7) and the drums (3) and (4), and at the same time, the drum (3).
(4) and the rider roll (7) rotate.

As a result, the paper (19) is wound around the core (14) by the double-sided adhesive tape E. This completes the operation of the paper edge adhering device to the core.

Next, in addition to the configuration shown in the above embodiment, the following modifications are possible. That is, as a method for attaching the double-sided adhesive tapes B and E to the surface of the paper (19) before cutting, the touch roll (8) was used in the above-mentioned embodiment. However, in addition to this method, both sides of the paper (19) before cutting (on the paper on the winding paper roll (2) side or on the paper (19) on the drum (3) side) previously attached to the surface of the linear member The adhesive tapes B and E may be contacted and transferred. The surface of the linear member is made of a material such as rubber or synthetic resin, which has a poorer adhesiveness than paper. Next, for the paper retainer (18) in FIG. 3, instead of this, a large number of holes are provided in the outer peripheral surface of the drum (3) to make the inside of the drum (3) a negative pressure and the paper (19) is adsorbed to the drum (3). Let paper (1
You may prevent slipping off of 9).

On the other hand, as shown in FIG. 4, when the paper edge (20) exists longer than the double-sided adhesive tape E, the paper edge (2
0) is doubled as shown in FIG. 5, and a step of winding is generated. If the paper (19) is thin, this step may be left as it is, but if not, it is preferable to eliminate it.

As this method, for example, double-sided adhesive tape E
May be attached in proximity to the rear end of the front double-sided adhesive tape B.

In this case, the drum (3) may be reversed and the double-sided adhesive tape E may be attached to the core (14).

Next, in the above-described embodiment, two rows of double-sided adhesive tapes B and E were attached to the paper (19), but the rear double-sided adhesive tape E was not supplied from the touch roll (8) and a new core (14 ) May be attached in advance.

[0029]

The method for tail-sealing a paper roll according to the present invention is as described above, and its effects are listed below. (1) In the tail-sealing method for a roll of roll of paper according to the present invention, since the double-sided adhesive tape is brought into contact with the paper and transferred, the application time of the double-sided adhesive tape is greatly shortened and the double-sided adhesive tape is actually applied before cutting. The above is possible and does not stain the device as when using glue. (2) Since the double-sided adhesive tape is attached to the uncut paper in the tail seal method of the present invention, it can be sealed before rolling the winding paper roll and the apparatus can be simplified.
