摘要

Process for manufacturing self-adhesive sheet materials applicable especially to materials of a frangible or unstable nature, consisting essentially of proceeding firstly to spread the layer of adhesive material on the surface of a non-stick sheet, such as a sheet of silicone paper or the like , which is then subjected to a process of drying and evaporation of the solvent through a hot tunnel, and secondly applied, already in cold, the face carrying the adhesive on a sheet or tape of the covering material not heat resistant or unstable composition, such as heat-sensitive plastic materials, solvents or tensile, said covering material being chosen such that it has a greater affinity for the adhesive than that which is proper of the non-stick material, with that, the indicated sheet of non-stick material can easily be detached by itself, separating the adhesive is deposited on it and said adhesive layer is transferred and applied on the surface of the sheet or tape frangible cover material, without it has undergone any of those operations that could harm or deteriorate it.
