Abstract

In a textile yarn twister, means for mounting idler pulleys and the drive tape tensioner spring transversely across the width of the twister between its opposing spindle rails resiliently. The pulleys are rigidly supported by and are interconnected with a transverse beam positioned between a pair of opposing spindle assemblies, the beam being vertically interconnected with each of the spindle rails by a resilient, vibration damping, isolation mount. Shock absorber elements are horizontally interposed between the transverse beam and the spindle rails to prevent shearing of the isolation mounts upon start-up or stoppage of the twister. Adjacent transverse beams are rigidly interconnected by elongate rigid members spaced away from the spindle rails to provide, in all, transverse and longitudinal stability of a plurality of the present mounting means relative the spindle assemblies associated therewith.

Dependent claims

In a textile yarn twister machine, having a plurality of spindle assemblies mounted upon rails and in a row therealong on each longitudinal side of said machine, and having drive means for rotationally driving the spindles of said assemblies to form packages of twisted yarn thereon, said drive means comprising a drive motor, a drive shaft from said motor extending longitudinal and intermediate said rows and power transmission interconnections joining said shaft to said assemblies comprising, for a pair of opposing assemblies, a drive drum secured to said shaft for rotation therewith, a plurality of idler pulley wheels intermediate said drum and said assemblies, a continuous drive tape interconnecting said pair of assemblies and entrained on peripheral surfaces of said drum and idlers, and a tape tensioning means to maintain said tape under sufficient tension to transmit power from said drum and through said idlers to said pair of spindle assemblies, the improvement comprising:

resilient mounting means for supportively and resiliently mounting said idlers and tape tensioning means intermediate said pair of opposing spindle assemblies in a stable condition transversely and longitudinally the machine, said mounting means comprising
resilient transverse support means for rigidly supporting said idlers and said tape tensioning means, for resiliently interconnecting said opposing spindle rails, and for resiliently separating said idlers and tape tensioning means from said spindle rails, and
rigid longitudinal support means for rigidly interconnecting a plurality of said resilient transverse support means in a direction longitudinal said machine, and being spaced away from said spindle rails.
