Process for the continuous antiadhesive treatment of an adhesive band, especially of a thermoplastic, extruded adhesive, and also the device for its processing and the corresponding product

Abstract

Abstract The invention relates to a method for the continuous anti-blocking treatment of a strip of permanent adhesive material, more particularly of a hot-melt adhesive exiting from an extruder-mixer or from a die at a temperature greater than its softening temperature, which method is characterised in that there is applied to at least a portion of the surface of the strip a coating of a anti-blocking agent compatible with the constituent material of the adhesive and which does not lead to any physico-chemical change in this material, the strip thus coated is cooled down, then it is cut up into the desired length and the fragments thus obtained are packaged directly, without additional precaution. The invention also relates to an apparatus for implementing this method.
