Abstract
Abstract Compressed fibers, filaments or cabled tows, which are under an internal pressure of at least 0.2 daN/cm 2 are packaged by means of an outer wrapping, and the overlapping areas of the wrapping are held together by means of an adhesive, for instance a neoprene-chloroprene-rubber based adhesive. In this manner, it is possible to eliminate straps, belts or wires which have been conventionally used to hold the package.
