ABSTRACT:
Tubular textile fabric is guided during longitudinal travel substantially without circumferential torque or twisting by a guide apparatus having a series of guide rings which open the tubular fabric into circular form, a drive ring affixed co-axially to the guide rings and mounted rotationally on the apparatus frame, and a drive motor connected to the drive ring through an endless drive belt for incremental reversible rotation of the drive ring and guide rings as a unit as necessary to counteract fabric torque or twisting. A linear guide stripe or line extends lengthwise along the tubular fabric and is monitored by a photo-optic sensor operable in conjunction with a microprocessor to control incremental and reversing operation of the drive motor as necessary to counteract detected non-linearities in the guide line which indicate the existence of fabric torque or twist.
