Abstract: A toothed power transmission belt with a smooth back side surface has a back jacket on the back side surface; wherein the back jacket comprises a closed-mesh, knit fabric tube. The fabric tube may be knitted on a circular weft knitting machine and may be heat set after knitting. The fabric tube may be treated with an epoxy, RFL or other treatment to provide for oil resistance, adhesion, frictional properties, etc.

Abstract: A V-ribbed belt that includes a ribbed surface covered with fabric is provided. The fabric is stretchable in two predetermined directions. A method for manufacturing the V- ribbed belt is also provided. The method includes placing a belt matrix about a mandrel, placing a fabric about the external circumference of the belt matrix which wraps around the mandrel, placing the mandrel inside a shell having a plurality of grooves on the internal circumference, expanding the belt matrix and the fabric toward the internal circumference of the shell and thus pressing the fabric onto the internal circumference having the multi-ribbed structure, and curing the belt matrix with the fabric. The fabric is stretchable to accommodate itself to the multi-ribbed structure.

Abstract: A synchronous belt drive system having: a synchronous belt with a tensile cord of high-modulus fiber such as glass, carbon, PBO, or aramid; a driver sprocket and at least one driven sprocket, at least one of which is an obround sprocket; and a tensioner having: a base having a cylindrical portion extending axially with a radially outer surface and a receiving portion, an eccentric arm pivotally engaged with the radially outer surface, a torsion spring disposed within the receiving portion, the torsion spring applying a biasing force to the eccentric arm, and a pulley journalled to the eccentric arm. Preferably, no one of the eccentric arm, pulley, or torsion spring is axially displaced along an axis A-A from the others. The obround sprocket has a toothed surface and at least one linear portion disposed between two arcuate portions having a constant radius, the linear portion having a predetermined length.

Abstract: A method of making weaving a tubular fabric (20, 40, 54, 55, 71, 73) of particular usefulness in power transmission belting and other technical applications. The method includes weaving a secondary, removable warp yarn (24) along with the primary warp yarn (14,42) in the region of the edge folds on a shuttle loom. The removable warp yarn may be a soluble or meltable yarn. The removable yarn is removed after weaving, resulting in substantially uniform warp density all around the tubular fabric.

Abstract: A cover fabric for a power transmission belt, the fabric woven from warp yarns and weft yarns; the warp yarns and weft yarns each plied from a first filament yarn and a second filament yarn; the first filament yarn comprising higher tensile strength fibers than the second filament yarn; and the fabric woven in a modified twill pattern. A toothed belt with the cover fabric on the teeth, oriented on a bias, with the fabric having a bias angle less than 90.
