Abstract

A fiber feeding system for feeding relatively short sliver fibers--less than one inch in length--to a sliver high pile fabric knitting machine. The system includes the usual basic elements of a carding head comprising the sliver feeding components, such as a pair of rotatable sliver feed rolls, a rotatable wire-covered doffer and a rotatable wire-covered main cylinder interposed between the sliver feeding components and the doffer. By utilizing a sliver feed plate as one of the sliver feeding components, together with one or more sliver feed rolls, the fiber pinch point may be advanced close to the periphery of the main cylinder. Where one or more pairs of sliver feed rolls are utilized without a sliver feed plate, each roll has a circumference not exceeding four times the minimum length of the sliver fibers. The peripheries of the main cylinder and doffer are provided with wire coverings whereof the individual wires have novel configurations designed to prevent excessive fiber build up, while permitting the fibers to be transferred by the main cylinder to the doffer in sheet form having a relatively thick and relatively narrow cross-sectional configuration. The invention contemplates the elimination of the main cylinder, whereby the sliver feeding components may feed sliver directly to the doffer.
