Abstract
A toothed drive belt having inner and outer reinforcing fabric layers. The inner layer has a large mesh size, is highly stretchable, has a fine warp of 30 to 210 d, has a normal weft, and the sum of the cover factors of the warp and weft are no more than 20. The inner layer may have either a flat or a wavy shape within the teeth. The outer layer has a low stretchability and a normal warp and weft. The inner layer, which is bonded strongly to the rubber substrate of the belt due to its large mesh size, easily follows the deformations of the teeth. Due to a small thread size, the amount of PLD is reduced.
