Zusammenfassung:	A positive drive belt (10) is provided which comprises a tension section (20) and a tooth section, which has a cushion section (28), and a load carrying section. A fabric layer (22) is disposed between the tension section (20) and the load carrying section (23). The tension section (20) may be a first compound and the load carrying section (23) may be a second compound. The fabric layer (22) is adapted to prevent intermixing of the first compound and the second compound during an associated cure cycle. As such, a positive drive belt (10) may be formed with two different compounds and formed in a single curing cycle.
