<p>In a deep pile fabric knitting machine which includes carding wheels from which fibers are transferred to rotary doffers and from which the fibers are selectively taken by knitting needles traveling with a rotary cylinder, but with at least some untaken fibers remaining on the doffers, remaining fibers are scavenged from the doffers, substantially uniformly dispersed and returned for recycling in the same carding paths from which the fibers were originally transferred to the doffers. Returned fibers may be applied directly to the perimeters of the carding wheels, or to sliver leading to the carding wheels. Scavenging may be effected by high speed scavenger rolls and return of the fibers effected pneumatically with mechanical dispersion. Loose fibers are blown from the knitting needles and recycled in the same system with the fibers scavenged from the doffers.</p> |
