ABSTRACT:
An apparatus for forming composite tows of uniform width comprises a tow tensioner mechanism which carries a reel having a length of tow of non-uniform width, a tow sizing unit, a drive roller unit and a tow winding device. A single tow is fed from the tensioner mechanism to the tow sizing unit where the side-to-side or width dimension of the tow is sized, and then the sized tow is transmitted through the drive roller unit to the tow winding device which winds the sized tow onto a reel. The tow sizing unit includes a rotatable sizing wheel having a circumferential flanged groove, and a presser roller, which cooperate to confine the tow on all four sides, i.e., top, bottom and opposed side edges, as the tow is pressed therebetween to form a finished, sized tow having a substantially uniform width.
