A resin belt includes: a plurality of teeth disposed at predetermined intervals along a longitudinal direction of the belt on a running surface of a belt body made of a thermoplastic resin; and a cloth covering the teeth. The cloth is a woven cloth obtained by weaving a thermoplastic synthetic resin fiber used as a warp yarn in the longitudinal direction of the belt and a fluorine resin fiber used as a weft yarn in a width direction of the belt. Crimp of the thermoplastic synthetic resin fiber used in the longitudinal direction of the belt is greater than crimp of the fluorine resin fiber used in the width direction of the belt.

This helically toothed belt power transmitting device (1) has: a toothed belt (10) having a plurality of teeth (12) tilted relative to the width direction of the belt; a drive pulley; and a driven pulley. The width of the helically toothed belt (10) is 1 mm to 20 mm, inclusive. The core (13) of the toothed belt (10) is a twisted cord containing high-strength glass fibers or carbon fibers and has a diameter of 0.2 mm to 0.9 mm, inclusive. The compressibility of the teeth (12) of the toothed belt (10) compressed by the grooves of the drive pulley and the driven pulley is 0% to 5%, inclusive.

The present invention provides a belt for a textile machine capable of reducing running noise caused during belt running. A canvas core used in the belt is constituted by a woven fabric based on a twill weave texture in which a warp crosses a plurality of wefts and aggregates (19) of weave points at which the warp crosses the wefts are regularly shifted in one longitudinal direction (L) of the belt to form a twill line (17), and some of the aggregates (19) in the twill line (17) are shifted at a predetermined interval in the opposite direction to the one longitudinal direction.

The invention relates to a force transmission belt, formed of at least one belt material (2) having a belt longitudinal direction and having a belt width extending transversely to the belt longitudinal direction, containing a belt back (1), a tension-bearing element zone (3) having a plurality of tension-bearing elements arranged adjacent to each other over the belt width at a distance and parallel to each other, and a force transmission zone (6) adjoining the tension-bearing element zone (3). Said force transmission belt can be formed simply, economically, and with improved running properties in that the tension-bearing elements are formed by at least two narrow strips (4) of a pre-stretched plastic material, which strips are arranged adjacent to each other over the belt width and are spaced apart from each other by belt material (2).
