<p>SPREADER-PROPELLER APPARATUS FOR TUBULAR KNITTED FABRIC A propeller-spreader for tubular knitted fabric is disclosed, in which internal, fabric edge engaging propeller belts are driven by means of magnetic coupling with internal, magnetic drive sheaves. A spreader frame, of flat configuration, arranged to laterally distend tubular knitted fabric to flat, two-layer form, is supported by means of a pair of spaced, transversely extending rollers. Magnetically coupled drive elements are positioned between the transverse support rollers and are driven to rotate in synchronism with the rotations of the support rollers. Ideally, the spreader frame is supported and positioned exclusively by means of the transverse support rollers, in conjunction with the magnetic attraction of the magnetically coupled drive means.</p> |
