Abstract
Process for manufacturing clutch discs and the like, consisting essentially of starting from asbestos yarn, with or without metal wire core, which is impregnated with phenolic or cresilic resin in liquid form, or with a solution of such resin, using for this purpose, a bath containing the resin in question, to which the fillers will have been added in suspension, substances to modify the friction and suitable colorants, and alternatively natural or synthetic rubber solutions may be used alternatively for this impregnation, with or without addition of added resins also of the fillers, colorants and other ingredients mentioned, other types of resin can also be used in conjunction with or in substitution of the mentioned phenolic resins, after which the impregnated asbestos yarn is dried by natural or forced process, passing to the preparation with the same of a disk preform that, after finished, is dried and subjected in turn to another drying process, followed by the cooking of the same in a mold suitable to the dimensions of the disk to be obtained, whose cooking is carried out under heat and pressure, until obtaining a set of the desired size, in which the cooked material is reinforced by an internal network of yarn and the ingredients are distributed throughout the mass, finally submitting the disk thus obtained to the machining operations for rectification of dimensions and final finishing.
