Abstract
An adhesive tape having a tape-like textile support and an adhesive coating applied to the support, wherein the tape can be unwound easily ready for use without special covering or treatment of the adhesive coating. A tape-like support comprises at least partially a needle punched nonwoven from at least partially thermoplastic fibers, in which the thermoplastic fibers are bonded to each other at least partially by melting on the side opposite the adhesive coating. Melting of the fibers preferably occurs by one-sided heat calendering of the support material. The surface produced by treatment of the fiber material prevents unduly strong adhesion with the following layer during winding of the tape and tearing out of the fibers from their bond during unwinding of the tape. A cost-effective textile adhesive tape from needle punched nonwoven is therefore created without additional interliner.
