<p>In a ring spinning machine the spindles are rotated sectionally by providing several pairs of endless drive belts (7a, 7b), the belts of each pair rotating an equal number of spindles on the two faces of the spinning machine (1). Each pair of belts (7a, 7b) is driven by its own drive member arranged symmetrically to the paths of the belts of the respective pair. The drive member consists of a drive pulley (8) driven either directly by a motor (9) or via a transmission connected to a central motor. Deviation pulleys (12) are associated with each drive pulley to cause the belts (7a, 7b) to pass about opposite sides of the pulley (8) through large winding angles involving the entire periphery of the pulley (8) or more, and thus improve the traction effect of the pulley (8). <IMAGE></p> |
