摘要

A textile machine producing cross-wound bobbins has thread processing units connected to a belt drive. The belt pulleys (10) have on both sides of an encompassing running surface (12) radially protruding securing elements (14) formed in one piece on the running surface for the positioning of the drive belt. The securing elements are spaced apart in the circumferential direction. The securing elements of both sides are offset in the circumferential direction in such a way that they do not overlap when viewed in the axial direction (16a,16b).
