发明名称 METHOD FOR PRODUCING ADHESIVE BLANKS FROM AN ENDLESS BAND AND BLANKS OBTAINED ACCORDING TO SAID METHOD
摘要 The invention relates to a method of producing adhesive die-cut articles with internal cut-outs 3 from an endless web 1, the web having a carrier layer 4, at least one adhesive layer 5 and, if appropriate, a matrix layer 6, and to a die-cut article produced by the method. In order to produce a die-cut article with an internal cut-out 3 whilst avoiding the use of a hollow punch, the contour 17 of the internal cut-out 3 and the external contour 10 of the respective die-cut article are die-cut out of the adhesive layer 5 and, if appropriate, the matrix layer 6 one after another, the external contour 10 not having any common point with the die-cutting line of the internal cut-out 3, the carrier layer 4 with the die-cutting residues from the internal cut-out 3 being pulled off over a pull-off edge, and the remaining web being transferred to a protective film 8.
