Abstract
A forward feed assembly for continuous forward feed of open tubular fabric to a subsequent processing station has an elongated guide mandrel over which the open tubular fabric passes, a first drive on one side of the guide mandrel operable to drivingly engage the fabric, and a second drive on an opposite side of the guide mandrel to drivingly engage the fabric at the same fabric-engaging speed as the first drive.
Claims2
A forward feed assembly for continuous forward feed of open tubular fabric to a subsequent processing station comprising:
- an elongated curved guide mandrel over which the open tubular fabric passes,
- pulley means on one side of the curved guide mandrel operable to drivingly engage the fabric, said guide mandrel curving through at least about 90.degree. around a portion of the circumference of the pulley means, and
- endless belt drive means on an opposite side of the curved guide mandrel to drivingly engage the fabric at the same fabric engaging speed as the pulley means as the fabric passes over the curved guide mandrel around the pulley means and to retain the curved guide mandrel in position around the pulley means.
