Abstract: The present invention consists of an apparatus and method whereby fibers such as cotton or otherwise are cleaned and carded prior to yarn formation to insure that the maximum quantity of fibers are utilized while removing substantially all non-lint from the fiber. Minimum fiber loss occurs while providing a sliver of excellent quality. The process herein includes the steps of carding the fibers whereby a portion of usable fibers, lint and other foreign matter are removed and are thereafter displaced to a condenser means. After condensing, the usable fibers which are still commingled with the waste are then extracted and recycled to the carding apparatus after blending with fresh stock in a uniform manner to provide a consistent blend for sliver formation or other uses.

Abstract: A ring doffer is provided for carded web splitting that prevents loading of the card cylinder during operation by employing a circumferential groove therein to effect the web splitting that is cut in a reversing helix pattern at a pitch exceeding the width of the groove.

Abstract: Significantly improved carding production capacity and materially lowered waste content in the resulting sliver is obtained by high-speed operation of the lickerin at a speed in the range of about 1400 to 2000 r.p.m. and related operation of the main cylinder at a speed such that the lickerin surface speed is in the order of 90% of the cylinder surface speed, with a stripper bar lickerin screen located specially below the lickerin.

Abstract: An improvement for collecting waste in a carding machine beneath the feed and lickerin rolls having a plenum chamber and duct with an inlet nozzle and a downwardly sloping collecting chute, and side doors enclosing a lickerin waste-collecting chamber provided with an opening through which air flow currents are induced to flow transversely and downwardly to remove and cause the flow of waste downwardly to the inlet nozzle of the plenum chamber.
