Abstract: Disclosed herein are devices and methods for manufacturing uncured, near-net shape plies. Such devices include: a plurality of spools, each dispensing a dry tow; optionally, a plurality of spreaders to spread the dry tows; optionally, a means to combine the dry tows into a plurality of tapes or bundles; a plurality of feeders, each carrying a tow, tape or bundle, and adapted to maintain the tows, tapes or bundles in a parallel arrangement; a cutting apparatus adapted to independently cut each individual tow, tape or bundle to a pre-determined length; optionally, a conveyor adapted to transport the cut tows, tapes or bundles away from the cutting apparatus; an in-line resin infuser adapted to impregnate the dry tows, tapes or bundles with resin material; and a receiver for the cut tows, tapes or bundles, wherein the cut tows, tapes or bundles are impregnated and configured in the form of a near-net shape ply.
