DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure-sensitive adhesive tape roll processing apparatus for making a cut in a pressure-sensitive adhesive tape roll, and more particularly, to a method for easily peeling off a pressure-sensitive adhesive tape by one turn. Therefore, the present invention relates to an adhesive tape roll processing apparatus that forms two cuts parallel to the adhesive tape roll.

[0002]

2. Description of the Related Art For example, when forming a wiring pattern on a printed board, it is necessary to remove dust from the surface of the board in advance. As one of the methods, there is a method using an adhesive tape roll wound with the adhesive surface facing up.

That is, according to this method, for example, one or both of a pair of upper and lower rollers are used and the printed circuit board is inserted between the rollers by using the above-described adhesive tape roll. Dust can be transferred to the adhesive tape side and removed.

Usually, since the printed circuit board is not so dirty, the adhesive tape can withstand several tens of uses. However, if the adhesive tape is used to some extent, its adhesive strength is reduced. Then, the next adhesive surface is exposed to restore the adhesive strength.

[0005] By the way, conventionally, the following method is used to peel off the used adhesive tape. Grasp the end of the adhesive tape, pull out the used part by one or more turns, and cut it with a cutter or the like. Cuts (cuts, etc.) for cutting in advance on the adhesive tape
Is provided, the used portion is pulled out by one or more turns, and when the cut comes out of the roll body, it is cut while being pulled along the cut.

[0006]

However, the above method requires a cutter and is difficult to cut straight. Not only that, the cutter is often lost, and if it is, it takes time to find it.

[0007] According to the above method, a cutter is not required, but the adhesive tape is cut while being pulled along the cut, so that the end of the cut is stretched and stretched. There were problems such as cut off from parts.

[0008] In addition, what can be said in common to both of them is that in any case, it is necessary to pull out the used adhesive tape from the roll body by one or more turns. Must be pasted on.

However, since the pressure-sensitive adhesive tape is made of a thin film and coated with a pressure-sensitive adhesive material, it is difficult to apply the tape neatly, and there have been problems such as wrinkles and bubbles being mixed between layers. That is, since wrinkles and bubbles cause unevenness, there is a portion that does not contact the printed circuit board surface, and there is a possibility that dust is left behind.

[0010]
