Abstract
A toothed belt includes a toothed profile made of a base material and defining a toothed profile drive side and a far side facing away from the drive side. A woven ply has a thickness and is applied to the far side of the toothed profile. The woven ply has a first side in contact with the far side causing the base material to penetrate the woven ply at least partly at the first side thereof. The woven ply has a second side facing away from the first side. A coating of plastic on the second side causes the plastic to penetrate the woven ply at least partly at the second side. The base material and the plastic each penetrate the woven ply to an extent to cause the woven ply to be free of the base material and the plastic in an inner lying thickness region thereof.
