Embodiment 1
[0084] The manufacturing method of the half-cut double-sided adhesive tape of Example 1 of this invention is demonstrated.
[0085] It should be noted that, in the following description, the drawing-out direction and the winding direction of the double-sided tape with release liner and the release tape for processing are referred to as "longitudinal direction", and the direction perpendicular to the longitudinal direction is referred to as "width". direction". Also in the half-cut strip-shaped small pieces, the direction along the longitudinal direction of the original adhesive tape is referred to as the longitudinal direction, and the direction corresponding to the width direction of the original adhesive tape is referred to as the width direction.
[0086] figure 1 It shows the flow of the manufacturing process of the half-cut double-sided tape manufacturing method 100 of Example 1 from the "processing protective layer forming step" to the "half-cutting step" and "half-cut...

On the basis of a double-sided adhesive tape with a peeling substrate, which can be obtained in the market, the double-sided adhesive tape after a half-cutting process is obtained by a simple step without directly contacting a cutting edge of a cutter with an adhesive layer during the half-cutting process. Comprises: a step for forming a processing protective layer on the double-sided tape (100) with a release substrate by respectively drawing out the double-sided tape (100) with the release substrate and a release paper tape (130) for processing, and bringing the double-sided tape (100) and the release paper tape (130) into contact with each other; a half-cutting step of continuously half-cutting the double-sided tape (100) with the peeling substrate on which the processing protective layer is formed to form a state in which a plurality of double-sided tape sheets having appropriate lengths are held on the peeling substrate (120); and a step for taking up the half-cut double-sided tape (100A) with the peeling substrate after the half-cut processing while peeling the peeling paper tape (130) for processing. In a half-cutting step, if a cut width-direction cut region and a non-cut width-direction non-cut region are formed in the width direction, peeling is easy.
Description
technical field [0001] The invention relates to a method for manufacturing a half-cut double-sided adhesive tape and a device for attaching a half-cut double-sided adhesive tape. [0002] A general double-sided tape is a tape in which the base material and the adhesive layers provided on both sides of the base material are integrated in a belt shape without a seam and is continuous, and the surface is supported by a release paper before it is attached and used. The "half-cut double-sided tape" is a state in which the double-sided tape is properly cut, and the surface is supported by a release paper before sticking and using. Background technique [0003] The general double-sided tape in the prior art is an adhesive tape provided with adhesive layers on both sides of a base layer, and is rolled into a roll with one side supported by a release paper tape before sticking and using. If the release agent is coated on both surfaces of the release paper, the release paper may be o...
