Definitions

  • Yarn so constructed is especially desirable and advantageous in the production of cut pile fabrics, since, through absence of entanglement between the fibers of the component ends, the formation of fabric imperfections such as pock mar and nigger heads are effectively precluded, and since by virtue of the unidirectionallow twist in the component ends and inthe doubling, the pile opens up readily and freely in the finishing with resultant production of a soft uniformly smooth face.

  • a pair of spaced holder pins I4 are provided on the creci-board 2 for each spinning and twisting section of the machine, and serve as supporting axes for spools I5 of prepared textile fiber roving strands R from which individual threads T are spun. As shown, the roving strands R. are drawn from the spools I5 by a set of nip rolls I6, including a fluted bottom roll I'I and a pair of laterally-spaced contacting upper rolls I8, which are individual to said strands.

  • constitutes a guard to keep the strands R in engagement with the sloping sides 33 of said block.
  • the block 30 can compensate for variations in the draft and tension induced by the lateral traversing of the rovings R and so insure a uniformly smooth and evenly twisted product.
