and an end piece fixedly attached to an end portion of said strip of tape, said end piece having a portion on one surface thereof including a second polymer having a second softening temperature lower than said first softening temperature, said first and second polymers forming a releasable surface connection when said second polymer is heated to said second softening temperature and pressed against any location on said elongated strip of tape. ### Claim 5 (depends on 4) A winding tape according to claim 4 wherein said first polymer is selected from the group consisting of polyesters, polyamides, polyimides, polyterephthalates, polycarbonates and polyolefins and said second polymer is a hot-melt adhesive containing polyamide-6, polyamide copolymers, polyester, polyolefins or polyvinyl alcohol. ### Claim 6 (depends on 4) A winding tape according to claim 4 wherein said end piece comprises a support fixed to one end of said strip of tape and a coating of said second polymer on an exposed surface of said support. ### Claim 7 (depends on 5) A winding tape according to claim 5 wherein said end piece comprises a coating of said second polymer on one surface of said end portion of said strip of tape. ### Claim 8 (depends on 7) A winding tape according to claim 7 wherein said one surface of said end portion is roughened for a firm connection with the hot-melt adhesive film. ### Claim 9 (depends on 5) A winding tape according to claim 5 wherein said end piece is a cloth support with an applied film of hot-melt adhesive. ### Claim 10 (depends on 5) A winding tape according to claim 5 wherein said end piece has substantially the same width and the same thickness as said strip of tape. ### Claim 11 (depends on 5) A winding tape according to claim 5 wherein said end piece contains a ferromagnetic material. ### Claim 12 A winding tape for winding-up and securing rolls of printed products comprising the combination of a plurality of elongated strips of tape each made of a first polymer having a first softening temperature; and a plurality of end pieces each fixedly attached to an end portion of one of said strips of tape, each said end piece having a portion on one surface thereof including a second polymer having a second softening temperature lower than said first softening temperature, said first and second polymers forming a releasable surface connection when said second polymer on one of said end pieces is heated to said second softening temperature and pressed against any location on one of said elongated strips of tape.
