ABSTRACT:
A multi-spindle double twist twisting machine having a belt drive assembly, a spindle frame formed to enclose the belt drive assembly, and traversing rod reciprocating means. The machine may be a horizontal spindle machine with two rows of spindles on each side. A beam mounted independently of the spindle frame extends along each side between rows and supports a drive belt for tangential driving contact with spindle whorls. The belts are commonly driven and reversing rolls are associated with one belt so that it travels opposite the other belt, and compensating rolls are associated with the other belt so that the belts may be of the same length. The spindle frame has two spaced support plates laterally outward of the belt drive assemblies and two cover plates secured to and extending between flanges on the support plates to form an enclosure for the belt drive assembly. The traversing rod reciprocating means uses a pulley and drive belt take-off from the drive shaft of one traversing rod reciprocating cam to drive a second cam so that only one drive motor, replaceable gear assembly and modulating gear assembly are required.
