を添着している。従って、接着剤の使用にあたっては、
セパレータを剥離する必要がある。(Prior art) Sheet-like adhesives, for example, sheet-like adhesives in which a base material such as a non-woven fabric is coated or impregnated with an adhesive, are coated with separators on both sides to protect the adhesive surfaces until use. is attached. Therefore, when using adhesives,
It is necessary to peel off the separator.
しかしながら、セパレータの厚みが極めて薄く、しかも
、セパレータと接着剤との間が密着しているので、セパ
レータの剥離は著しく困難である。However, since the separator is extremely thin and the separator and adhesive are in close contact with each other, it is extremely difficult to separate the separator.
このため、セパレータに所謂、タブを設け、このタブを
摘んでセパレータを剥離することが知られている。For this reason, it is known to provide a so-called tab on the separator and to peel off the separator by picking the tab.

接着剤耳部１ゲを切断除去することが公知である。As a method for producing such a sheet-like adhesive having separators with tabs on both sides, a raw material with upper and lower separator materials attached to the upper and lower surfaces of the sheet-like adhesive surface, respectively, is punched as shown in Fig. 6. As shown,
It is punched into a contour shape having ears 210', and then the upper separator ears 21a' and the lower separator ears 21b' are each peeled off from the adhesive ears 10',
It is known to cut away adhesive ears.

ことがある。(Problem to be Solved) However, even in this manufacturing method, it is difficult to separate each separator ear from the adhesive ear and requires skill. In addition, it is often the case that the entire separator is peeled off instead of just the separator material being peeled off, and in this case, when the separator is reattached, misalignment occurs between the separator and the adhesive, and the edge of the adhesive The part protrudes,
When the adhesive is a pressure-sensitive adhesive, dirt adheres to the edge of the adhesive that protrudes, and this may cause edge peeling of the adhesive interface.
