Abstract
Continuous anti-adherent treatment process for a surface-tacking thermofusible adhesive, characterized in that a carrier belt (1) is continuously displaced in translation, the upper surface thereof being cooled by its lower face, said surface being covered by a layer (3) of an anti-adherent protection product, the thermofusible adhesive (4) to be treated being deposited on the protection product layer. The assembly (7) comprising of the adhesive (4) and the layer (3) of protection product is folded back on itself so as to release a composite material (8) consisting of a double thickness (4, 4') of thermofusible adhesive sandwiched between two layers (9, 9') of anti-adherent protection product (3) and the composite material is cut into fragments.
