ABSTRACT:
A belt type spindle drive apparatus for textile machines of the type having a plurality of simultaneously driven aligned spindles arranged in at least one row. An endless belt extends in driving engagement along the spindles and is driven by a plurality of belt driving devices. In one embodiment, the belt driving devices have drive rollers offset from the spindle rows and coaxial overlapping input and output rollers that guide the belt to and from the drive roller between adjacent spindles. The paths of the belt entering and leaving the drive devices are offset. When an uneven number of devices is used, a pair of canted auxiliary rollers are used to make the number of belt path offsets even. To accommodate the offset of the guide rollers, one or the other guide rollers can be canted toward the drive roller or the drive roller can be canted. Alternatively, adjacent drive devices can have the same offset relationship and the belt path can be inclined from one drive device to the other. In another preferred embodiment, the input and output guide rollers are coplanar, but a spindle intermediate the rollers is not contacted by the guided belt. Rather, an additional belt is provided around an additional drive roller mounted on and driven by the input guide roller and a driven roller mounted on the output guide roller, with the additional belt thereby engaging and driving the intermediate spindle.
