FIELD: process engineering.
SUBSTANCE: invention may be used for production of long sheet reinforced fluoroplastic billets for friction assembly operated without lubrication. Polydisposed polymer film is produced from fluoroplastic-4 or from compositions based thereon. Strip mesh power are filled by said film by rolling said film on both sides. Produced sheets are wound on rolls to be fitted in limiting mandrels with no clearance. Billets are sintered at 643-653 K and pressure developed by expansion of fluoroplastic-4 and cooled down thereafter. Billets are withdrawn from mandrels and passed through rolls.
EFFECT: simplified procedure, expanded range of products.
