Abstract

PURPOSE:To accumulate a pressure sensitive adhesive exuding at adhesive sheet cutting time in a recessed part, and restrain the degradation of the cutting quality of rotary edges caused by the pressure sensitive adhesive by forming the recessed part in parallel with a ridgeline in the lengthwise direction on the reverse side of a fixed edge meshed with the rotary edges. CONSTITUTION:In a cutter to cut an adhesive sheet SH, a plate-like fixed edge 1 and rotary edges 2 whose ridgeline 2a in the lengthwise direction crosses obliquely a ridgeline 1a in the lengthwise direction, are meshed with each other. The rotary enges 2 are installed on the outer peripheral surface of a holder 3. In this case, a recessed part 1c in parallel with a ridgeline la in the lengthwise direction is formed on the reverse side of the fixed edge 1. A pressure sensitive adhesive exuding at adhesive sheet SH cutting time is accumulated in the recessed part 1c of the fixed edge 1. Thereby, since the exuded pressure sensitive adhesive is prevented from coming into contact with the ridgeline 2a in the lengthwise direction of the rotary edges 2, the cutting quality of the rotary edges 2 is prevented from degrading in its early stages.

The pressure-sensitive adhesive SH is obtained by applying a pressure-sensitive adhesive SH2 on the lower surface of the cover sheet SH1 and then pasting a protective release paper SH3, and supplying the cover sheet SH1 side up. . Further, the fixed blade 1 is positioned, for example, by a circular stopper (not shown) fixed to the shaft 3a so that the ridgeline 1a contacts the rotation locus of the ridgeline 2a of the rotary blade 2. Instead of rotating the rotary blade 2 in the direction of arrow K2 in the figure, the shaft 3a may be rotated forward and backward by a predetermined angle so that the ridgeline 2a reciprocates up and down the ridgeline 1a.

According to the prior art, the cutting operation is repeated to form a mass A of the pressure-sensitive adhesive on the upper portion of the ridge line 1a on the back surface side of the fixed blade 1 to form a cutter. There is a problem that the cutting performance may deteriorate early. That is, when the rotary blade 2 is rotated to cut the adhesive sheet SH, a slight amount of the pressure sensitive adhesive SH2 leaches out from the cut end surface, and as the rotary blade 2 rotates, it is rubbed up on the back surface side of the fixed blade 1. This is because, as a result of being adhered and adhered and gradually accumulated, a large amount of pressure-sensitive adhesive adheres to the ridgeline 2a of the rotary blade 2 and hinders its sharpness.

The deterioration phenomenon is caused by the pressure-sensitive adhesive sheet SH.
Although the pressure-sensitive adhesive SH2 used in Example 2 has a different degree depending on the type and properties, in the case of a certain kind of adhesive sheet, the cutting performance as a cutter was remarkably lowered after cutting about 300 times. At this time, the cutting performance can be restored by cleaning the back surface side of the fixed blade 1 and removing the accumulated mass A of the pressure-sensitive adhesive. However, if the deterioration is too early, there is a problem that the cleaning work becomes too complicated.

When the pressure-sensitive adhesive sheet SH is cut in this manner, a slight amount of the pressure-sensitive adhesive SH2 leaches from the cut end surface of the pressure-sensitive adhesive sheet SH. However, the leaching pressure-sensitive adhesive SH2 is rubbed along the back surface side of the fixed blade 1 and enters the concave portion 1c of the fixed blade 1 every time the rotary blade 2 moves from the standby position to the cutting position. That is, the leached pressure-sensitive adhesive SH2 is deposited in the concave portion 1c and forms a solid B, so that it does not adhere to the ridge line 2a of the rotary blade 2 in a large amount and the sharpness of the ridge line 2a may be deteriorated. There is no. By the way, according to the fixed blade 1 of FIG. 1, even if the adhesive sheet SH was cut 3000 times or more, the cutting performance as a cutter was hardly deteriorated. However, the pressure-sensitive adhesive sheet SH used at this time was the same as the pressure-sensitive adhesive sheet SH in which the remarkable cutting performance deterioration was caused by cutting about 300 times in the conventional example of FIG.

In the above description, the concave portion 1c formed in the fixed blade 1 should be such that the pressure sensitive adhesive SH2 leaching from the cut end surface can be smoothly deposited every time the adhesive sheet SH is cut, and its sectional shape is , And can be changed arbitrarily (FIGS. 4A and 4B). However, the concave portion 1c
In order to facilitate the entry of the pressure sensitive adhesive SH2 and the removal of the solid B formed in the recess 1c, the bottom corner should be curved in an arc shape, and the side close to the ridge line 1a should have the deepest asymmetric cross section.
