POWER TRANSMISSION BELT OF THE TRAPEZOIDAL TYPE

摘要

A power transmission belt of the trapezoidal type comprising a body made of an elastomer matrix having a layer of cord embedded therein, the cord being made of synthetic or natural textile material and serving as a traction strength member, the belt also including reinforcing numbers based on fibers extending substantially transversely relative to the belt. The reinforcing members are rigid composite pins made of glass fibers coated in epoxy resin and they are disposed in the outside or back portion only of the belt, which portion is delimited by two side faces that are set back to avoid any contact between the reinforcing members and the cheeks of pulleys with which the belt may cooperate.
