A conveyor belt having a width and a length, and a longitudinal centerline, also has a first longitudinal edge, and an opposing second longitudinal edge and a load bearing region. The load bearing region is located evenly about the belt longitudinal centerline, throughout the length of the belt. The conveyor belt also has a first flexibility region and a second flexibility region, wherein the first flexibility region is located between the first longitudinal edge and the load bearing region, and the second flexibility region is located between the second longitudinal edge and the load bearing region. The conveyor belt further comprises at least one fabric layer, having a width corresponding to the conveyor belt width, and having a length corresponding to the conveyor belt length, wherein the fabric layer has a density which varies over the fabric layer width; and wherein the fabric layer density is higher in the first and second longitudinal edges and the load bearing region than the fabric layer density in the first and second flexibility region.

The present invention is directed to an endless power transmission belt having an elastomeric body and at least one treated textile fabric, the treated textile fabric including a first treatment including a polyamide and an epoxy; and optionally, a second treatment including an RFL adhesive.

Power transmission belt

An endless transmission belt having a tension section, a cushion section, a load carrying section disposed between the tension section and the cushion section, at least one drive surface having a fabric layer bonded to an outer surface of the belt and a layer of thermoplastic located between the fabric layer and the cushion section of the power transmission belt.

An endless power transmission belt comprising a tension section, a cushion section and a load-carrying section disposed between the tension and the cushion sections, and at least one drive surface having fabric layer bonded to an outer surface of the belt is coated with a layer of polyvinylidene fluoride.
