Abstract

A sealing strand, in particular for processing during continuous feeding and separation of use portions, including multiple strand parts each of which are connected to one other at abutting ends, and including a double-sided adhesive tape. A removable protective strip covers the tape adhesive surface facing away from the remaining sealing strand. The protective strip has a butt strap at each of the butt joints. The butt strap overlaps the abutting ends of the protective strip portions of the strand parts. Each connection between the butt strap and the overlapping abutting ends of the protective strip portions of the strand parts begins only at a distance from the butt joint. The connection of the butt strap to at least one of the two overlapped abutting ends begins in a region in the strand longitudinal direction of consecutive separating cuts in the abutting end.

Dependent claims

A sealing strand, comprising:

a plurality of strand parts that which are in each case connected to one another at abutting ends;
a double-sided adhesive tape provided on each of the strand parts and having an adhesive surface that faces away from the sealing strand;
and a removable protective strip on the adhesive surface, wherein the protective strip, at butt joints of the abutting ends of the strand parts, has a respective connecting tab that overlaps abutting ends of the protective strip of the strand parts, and wherein a connection between the connecting tab and the overlapped abutting ends of the protective strip portions of the strand parts in each case starts only at a distance from the butt joint, wherein the connection of the connecting tab to at least one of the two overlapped abutting ends starts in a region of successive separating cuts, which follow one after another in a strand longitudinal direction, in the abutting end of the protective strip portion.

Dependencies are inferred from the claim text.
