ABSTRACT:
Disclosed is a new roller drafter for drafting and aligning fibers in a strand or strip of card web e.g. for producing filament-wrapped yarn. The improvements include, increasing (in the direction of strip or strand movement) the distances between nips of adjacent pairs of rolls and optionally increasing in said direction of strip or strand movement the outer diameters of each pair of rolls. Also disclosed are, a process utilizing said roller drafter (optionally with filament wrapping), and a drafted strand or strip and a wrapped yarn which are products of the present invention.
