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.
Procédé de traitement anti-adhérent un continu d'un adhésif thermofusible collant en surface, caractérisé en ce qu'on déplace constamment en translation un tapis transporteur (1) dont on refroidit la surface supérieure par sa face inférieure, on recouvre cette surface par une couche (3) d'un produit de protection anti-adhérent, on dépose l'adhésif thermofusible (4) à traiter sur la couche de produit de protection, on replie sur lui-même l'ensemble (7) constitué par l'adhésif (4) et la couche (3) de produit de protection de façon à libérer un matériau composite (8) constitué par une double épaisseur (4, 4') d'adhésif thermofusible prise en sandwich entre deux couches (9, 9') de produit de protection anti-adhérent (3) et on découpe ce matériau composite en fragments.
