METODO PER LA REALIZZAZIONE DI UN RULLO MATRICE PER LA STAMPA DIRETTA DI PIASTRELLE

摘要

A method for the manufacture of a matrix roller (1) for the printing of tiles comprising the steps of providing a cylinder (2) made from rigid material; fixing a pair of ferrules (3) at the two ends of the cylinder (2); inserting said cylinder (2) with ferrules (3) in a mould (5) forming a first annular chamber (6); injecting a first yielding substance inside said first annular chamber (6), to form a first layer (7); removing the cylinder (2) from the mould (5) and replacing the pair of ferrules (3) with a pair of crowns (8); turning said first layer (7); inserting the cylinder (2) including said turned first layer (7) and the pair of crowns (8) fixed at the two ends in a rotary mould (12) forming a second annular chamber (13); feeding a second substance inside the second annular chamber (13), said second substance having less elastic deformability than the first yielding substance and reticulating around it to form a second layer (14); removing said matrix roller (1) thus obtained from said rotary mould (12).
