A conveyor belt, power transmission belt or machine tape (1) being open-ended with two ending edges (6, 7) and with a longitudinal length (L) in a longitudinal direction, comprising: a) two parallel lateral edges (la, lb) running in said longitudinal direction, and being spaced apart from each other by a transversal width (W); b) a first textile layer (2); c) a first coating layer (3); and optionally d) one more through holes (5) perforating the belt through its overall thickness (T), each of these through holes (5) being formed by a hole edge (5a); characterized in that i) the first textile layer (2) comprises fibres or filaments of a thermoplastic and/or the first coating layer (3) comprises a thermoplastic or thermoplastic elastomer; and ii) the lateral edges (la, lb) are ultrasound-cut or laser-cut and/or the optional hole edge(s) (5a) is(are) laser-cut. The belt or tape has melt-sealed edges, can be made endless by conventional end-joining and can be used in fluff-generating environments, such as a spindle tape.

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.
