Metodo de fabricacion de un refuerzo de tela que comprende impregnar un material de tela con un agente de union en un plastisol para formar un material de tela recubierto, aplicar una capa de plastisol entre dos o mas capas de tela, alimentar la carcasa formada a una prensa de doble cinta y calentar entre 182-232°c durante 6 min.

摘要

The present invention reveals a method of manufacturing a fabric reinforcement having improved peel adhesion characteristics which is of particular value in reinforcing endless belts, wherein at least two layers of fabric material are embedded in the fabric reinforcement, said process comprising (1) impregnating a fabric material with a bonding agent in a plastisol to form coated fabric material, (2) applying a plastisol layer between two or more layers of coated fabric thereby creating a belt carcass, (3) continuously feeding the belt carcass into a double belt press which presses the impregnated fabric materials together with the plastisol layer(s) at a pressure of at least 5 psi (34,500 Pa) to produce a preformed fabric carcass while (4) heating the preformed fabric carcass to a temperature which is within the range of 360°F (182°C) to 450°F (232°C) for a period of at least 6 minutes, and (5) continuously withdrawing the fabric carcass from the press.
