Abstract: A new and improved positive drive belt is provided which comprises a tension section and a tooth section, which has a cushion section, and a load carrying section. A fabric layer is disposed between the tension section and the load carrying section. The tension section may be a first compound and the load carrying section may be a second compound. The fabric layer is adapted to prevent intermixing of the first compound and the second compound during an associated cure cycle. As such, a positive drive belt may be formed with two different compounds and formed in a single curing cycle.
