Abstract: Described herein is a tensioner device, and assemblies and methods of manufacture thereof. The tensioner device may be adapted to create a target tension in an associated belt based on the measured length of the belt. The tensioner device may include an engagement member having a surface adapted to engage the belt and a biasing element associated with the engagement member. The biasing element has a loaded configuration that causes the engagement member to exert a force on the belt to create the target tension. In one example, the biasing element is manipulated into a loaded configuration so that the biasing element exhibits a deflection and an effective spring rate for creating the target tension. The belt may be trapped within the tensioner device with a bracket assembly enclosing one or more runs of belt relative to the engagement member.

Abstract: A cover fabric for power transmission belts having two or more alternating stripes or bands of different frictional properties. The stripes may be different fabric constructions. The fabric may be woven or knit with stripes of different area or yarn densities, different permeabilities, or different openness. The fabric may cover a surface of a V-ribbed-belt, V-belt, toothed belt, flat belt, round belt or other drive belt, resulting in stripes having different amounts of rubber strike through or different coefficients of friction. The stripes may be different rubber compositions or flocking or other materials.
