Abstract

A toothed power transmission belt (10) is manufactured by an improved method to have substantially improved resistance to tooth root face cracking. The manufacture utilizes a modified rubber blend forming the teeth (15) and may utilize the same blend for embedding the load-carrying cords (14) to provide improved bonding of the teeth (15) to the cords (14) over a wide range of temperatures.
