BAND WITH ABRASIVE COATING

摘要

FIELD: mechanical engineering. SUBSTANCE: band consists of nonwoven base and abrasive coating. Base is made as flexible seamless loop. It contains organic polymeric binding material and fibrous reinforcing material in quantity of 1-60% of base mass. Surfaces which form base loop are parallel to each other over entire loop length. At least one layer of fibrous reinforcing material is immersed in organic polymeric binding material. Base consists of noncrossing layers of fibrous reinforcing material immersed in organic polymeric binding material. Layer of fibrous reinforcing material includes layer formed from one continuous fibrous strand wound as spiral over length of loop-base and capable of longitudinal extension. Layer formed from continuous fibrous strand is wound by turns following at constant angle relative to parallel surfaces of loop-base. EFFECT: improved composition. 9 cl, 12 dwg, 3 tblt
