Power transmission belt

摘要

A power transmission belt having a load carrier in which a twisted cord of synthetic fiber such as polyester fiber or of inorganic fiber such as glass fiber is embedded. Said load carrier is made by final twisting a plurality of twisted yarn (one or plural single yarns first twisted) in the direction contrary to the first twisting direction. The first twisting angle should be in the range between 87 DEG and 93 DEG and the final twist multiplier should preferably be in the range between 400 and 1,600.
