ABSTRACT:
Disclosed are apparatus and methods for converting tow into sliver including cutter rolls for cutting fiber to length, a collector pan for passing the cut fiber from the cutting rolls to a drafting section and a pin roll in the drafting section for combing and debonding the fiber. The collector pan is shaped to dispose the opposite marginal edges of the cut fiber web in registration with the main body of the web to ensure proper presentation of the cut tow fibers to the drafting section. The pin roll in the drafting section includes a plurality of projections having leading and trailing edges terminating in a tip. Each leading edge is angled to enter the tow web prior to entry of the associated tip. The arrangement of the converter affords high weight delivery of combed and debonded fiber with minimal defects.
