    Abstract: 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.

    Abstract: The present invention relates to an adhesive tape and to a method for jacketing an elongated item, more particularly cable sets. The adhesive tape must cure within the operational dictates for further processing, e.g. within 6 min, and after curing must exhibit the required dimensional stability properties. However, the adhesive compositions must not cure during storage itself, since otherwise they can no longer be used. Nor may the curing temperatures be too high, since otherwise the lead insulation, which is often made of PVC, may suffer damage. The invention proposes a method for jacketing an elongated item such as more particularly leads or cable sets, where a tape which comprises a moisture-curing binder on a carrier is first impregnated with water and immediately thereafter is guided in a helical line around the elongated item or the elongated item is wrapped in an axial direction by the adhesive tape, the elongated item together with the adhesive tape wrapping is brought into the desired disposition, more particularly into the cable set plan, the elongated item is held in this disposition, while the curable adhesive cures. Alternatively proposed is a method for jacketing an elongated item such as more particularly leads or cable sets, where a tape which comprises a moisture-curing binder on a carrier is guided in a helical line around the elongated item or the elongated item is wrapped in an axial direction by the adhesive tape, the elongated item together with the adhesive tape wrapping is brought into the desired disposition, more particularly into the cable set plan, the elongated item is held in this disposition, and the curable adhesive is brought to cure by the supply of moisture.

Nor may the curing temperatures be too high, since otherwise the lead insulation, which is often made of PVC, may suffer damage. The invention provides a method for jacketing an elongated item such as more particularly leads or cable sets, where a stretched shrink-wrap film is guided in a helical line around the elongated item or the elongated item is wrapped in an axial direction by the stretched shrink-wrap film, the elongated item together with the shrink-wrap film wrapping is brought into the desired disposition, more particularly into the cable set plan, the elongated item is held in this disposition and the shrink-wrap film is brought to shrink by the supply of thermal energy at a temperature of up to 130° C.
