The invention relates to a method for jacketing elongate articles, such as lines or cable harnesses in particular, by means of an adhesive tape comprising a tape-shaped substrate, which substrate has, on at least one side, a thermally curable, meltable, preferably pressure-sensitive adhesive layer, the adhesive layer comprising an epoxide-functionalized acrylonitrile-butadiene copolymer which has on average more than 1.5 epoxide groups per molecule and comprising the reaction product of phthalic anhydride and diethylene-triamine, the adhesive tape being led in a helix around the elongate article or the elongate article being enveloped by the adhesive tape in the axial direction, the elongate article together with the enveloping adhesive tape being brought into the desired arrangement, in particular into the cable harness plan, the elongate article being held in this arrangement, and the curable adhesive mass being cured by supplying thermal energy, in particular at a temperature of up to 110° C.
A method comprising jacketing an elongated item with an adhesive tape comprising a tapelike carrier provided on at least one side with a thermally curable, meltable adhesive layer, wherein the adhesive of the adhesive layer can be processed in a temperature range between approximately 40° C. and 60° C. as a melt in a compounding and extruding operation, the adhesive layer comprising an epoxide-functionalized acrylonitrile/butadiene copolymer having on average more than 1.5 epoxide groups per molecule of the copolymer and the reaction product of phthalic anhydride and diethylenetriamine, said method comprising (a) guiding the adhesive tape in a helical line around the elongated item or (b) wrapping the elongated item in an axial direction with the adhesive tape to yield in the case of both (a) and (b) an elongated item wrapped with the adhesive tape, bringing the elongated item wrapped with the adhesive tape into a desired disposition, holding the elongated item wrapped with the adhesive tape in this disposition, and curing the thermally curable, meltable adhesive layer by the supply of thermal energy, wherein the thermally curable, meltable adhesive layer will completely cure at a temperature of up to 110° C.
A method comprising jacketing an elongated item with an adhesive tape comprising a tapelike carrier provided on at least one side with a thermally curable, meltable adhesive layer, wherein the adhesive of the adhesive layer can be processed in a temperature range between approximately 40° C. and 60° C. as a melt in a compounding and extruding operation, the adhesive layer consisting of:
