Accordingly, each of the supply rollers 120 and 130 is selectively restrained by the frictional force of the friction piece 182 as the friction piece 182 comes in contact with the outer circumferential surfaces of the rotation shafts 121 and 131, thereby providing a first double-sided tape 10. ) And the second release paper 21 is to maintain a tension that is not tensioned.

On the other hand, the first double-sided tape 10 and the second release paper 21 withdrawn from each of the supply rollers 120 and 130 are driven to the drive take-out roller 141 by the operation of the pressure regulating member 190 (FIG. 4). The tension is adjusted by adjusting the pressing force of the take-out roller 142.

More specifically, as shown in FIG. 4, first, the adjusting piece 194 is rotated in one of two directions to advance and retract the screw rod 192.

Subsequently, as the threaded rod 192 is moved forward and backward, the threaded rod 192 tensions or relaxes the tension spring 193 connected to the upper end of the threaded rod 192 and the support piece 143, and the driven pull-out roller. 142 presses the outer circumferential surface of the drive take-out roller 141 while hinge-moving about the hinge pin 144 with respect to the support piece 143 as the tension spring 193 is selectively tensioned or relaxed. Then, the first double-sided tape 10 and the second release paper 21 maintains a tension that is not tensioned by the pressing force of the driven take-out roller 142.

As shown in FIG. 5, the first double-sided tape 10 and the second release paper 21 withdrawn from each of the supply rollers 120 and 130 pass between the drive take-out roller 141 and the driven take-out roller 142. When the second release paper 21 is adhered to the back surface of the double-sided adhesive tape 11 of the first double-sided tape 10, the first double-sided tape 10 and the second release paper 21 adhered to each other are wound rollers ( As the 150 and 160 are rotated by the driving source M, the driving is performed toward the winding rollers 150 and 160.

Next, the first double-sided tape 10 and the second release paper 21 adhered to each other are close to the winding rollers 150 and 160, and the second double-sided tape to which the second release paper 21 is adhered to the double-sided adhesive tape 11 ( 20) and the first release paper 12.

Subsequently, the second double-sided tape 20 is wound on the second double-sided tape winding roller 150, and the first release paper 12 is wound on the first release paper winding roller 160. At this time, the second double-sided tape 20 and the first release paper 12 which pass between the drive take-out roller 141 and the driven take-out roller 142 and are wound on each of the winding rollers 150 and 160 are the control unit 170. It is controlled by the drive take-out roller 141 is rotated at a rotational speed relatively smaller than the rotational speed for each of the winding rollers (150, 160), thereby maintaining a tension that is not tensioned. In addition, since the first release paper winding roller 160 is controlled by the control unit 170 and rotates at a rotational speed relatively larger than the rotational speed with respect to the second double-sided tape winding roller 150, the first release paper 12 Is easily separated from the double-sided adhesive tape 11.

Accordingly, when the second double-sided tape 20 having the desired length is wound in the shape of a roll on the second double-sided tape winding roller 150 by continuously repeating such an operation, a second wider than the width of the double-sided adhesive tape 11 is obtained. Production of the roll-shaped double-sided tape to which the release paper 21 is bonded is completed.

As described above, the release paper bonding apparatus of the double-sided tape according to a preferred embodiment of the present invention has the following effects.

First, since the double-sided adhesive tape having the same width and the release paper is bonded to the conventional double-sided tape to remove the double-sided adhesive tape and has a structure that can be bonded to a release paper having a wider width than the double-sided adhesive tape, Without replacing the existing manufacturing equipment for manufacturing the tape, the release paper having a width larger than the width of the double-sided adhesive tape by using the conventional double-sided tape by a simple structure while manufacturing the double-sided tape with the existing manufacturing equipment Double sided tapes can be produced.

Second, it is possible to not only promote the market of double-sided tape manufactured by the existing manufacturing facilities, but also significantly reduce the stock.

Third, since the tension cutting member and the pressure adjusting member are provided, it is possible to selectively adjust the tension of the first double-sided tape and the second release paper drawn from the respective supply roller to the draw roller member side.
