The cutting blade 210, the joining base opening 60 and the joining plate 50 come down together by the operation of the motor 40 in the state of being in the state, and the upper end of the joining plate 50 passes through the separation gap 400 between the base bracket 10 and the joining base 30. Come to come.

At this time, the roll tape end portion 310 that is inserted into the separation gap 400 and bent and folded while matching each other between the adhesive surfaces remains in the separation gap 400 and the roll tape end portion 310 slips. The non-adhesive surface is matched with the joining base 30 and the base bracket 10, but the non-adhesive surface of the roll tape is brought into contact with the roll tape non-slip rubber plate 33 on the inner surface of the joining base 30, so that the joining plate 50. The roll tape end portion 310 that has been folded even if it comes out of the separation gap 400 is not detached from the separation gap 400.

While the joining plate 50 slips through the separation gap 400 between the base bracket 10 and the joining base 30 and descends, the opening leg 62 of the joining base opening 60 that has lifted the joining base 30 also descends by the push plate spring 20. The pressure-sensitive adhesive surface of the roll tape end portion 310 that is folded while the joining base 30 is pressed is joined.

The roll tape end 310 bonded to form a non-adhesive surface in this way is pulled out from the separation gap 400 while the roller 110 is retracted by a transfer motor (not shown), moves backward, and moves forward while spreading horizontally. Then, it passes through the roll tape cutting device 200 and is supplied.

On the other hand, FIG. 5 is a perspective view of a state in which the locking metal fitting and the lever according to the present invention are bent to a position where the end of the tape is not folded, and FIG. 6 is a roll tape in the state of FIG. FIG. 6 is a cross-sectional view showing a working state in which the roll tape is pulled out and fed in a general state where the end of the roll tape is not folded when the machine operates in this state.

That is, when the handle 563 of the lever 560 is operated to move the latching metal 540 and the latching metal 540 is moved to the side and the lower end of the receiving groove 55 of the joining plate 50 is opened, The slot 65 and the long space 65 of the joint opening 60 allow the movement of the lifting shaft 523. If the lifting shaft 523 is raised by the operation of the motor 40 in this state, only the cutting blade 210 is lifted. Since 300 is cut and the joining plate 50 and the joining stand opening 60 are not raised, the tape folding action does not occur.

In this way, a non-adhesive surface can be formed at the end of the tape or pulled out in a general form only by moving the locking fitting 540 by operating the lever 560.
