Manufacturing method of half-cut double-sided tape and half-cut double-sided tape sticking device

A manufacturing method for manufacturing a double-sided tape with a release liner, which comprises a double-sided tape having a base material layer and an adhesive layer disposed on both sides of the base material layer, and a release liner covering the adhesive layer on one surface of the double-sided tape, comprising

• a processing protection layer formation step of feeding a protect release paper tape having the release surface to the double-sided tape to form a processing protection layer on the double-sided tape with the release liner;
• a half-cut step of continuously performing half-cut together with the processing protection layer and the double-sided tape on the release liner while leaving only the release liner, and making a number of the double-sided tape pieces of proper length that are held on the release liner;
• and
• a half-cut double-sided tape winding step of winding the half-cut double-sided tape with the release liner while peeling off the processing protection layer;
• wherein the width of the protect release paper tape for processing is larger than that of the double-sided tape with the release liner and larger than that of the half-cut in the half-cut process, and
• wherein the width of the half-cut in the half-cut process is equal to or larger than that of the double-sided tape with the release liner, and smaller than that of the protect release paper tape.
