POLY-V BELT COMPRISING A LAYER OF THERMOPLASTIC MATERIAL AND A KNITTED FABRIC EMBEDDED IN AN ELASTOMERIC LAYER

摘要

Poly-V belt comprising a body made of elastomeric material, preferably EPDM, a plurality of threadlike resistant inserts longitudinally embedded in the body, and a coupling portion integrally connected to the body and comprising a plurality of V-shaped ribs arranged side by side and alternated with V-shaped grooves. According to the present invention the belt comprises a layer of a thermoplastic material which covers the ribs at least partially, and a layer of elastomeric material in which a knitted fabric is embedded. The layer of elastomeric material is above and in contact with the thermoplastic material.
