Abstract

A fiber transfer system for feeding fibers to the needles of a sliver high pile fabric circular knitting machine, in which the width of the fiber transfer path from the feed rolls to the needle line at the doffer is constant. Adjustable sliver entrance guides accurately direct the roving into the feed rolls and determine the location and width of the fiber transfer path. A continuous film of fibers of selected width and uniform density is transferred from the feed rolls via the main cylinder and doffer to the knitting machine needles. The main cylinder preferably is of a greater axial width than the doffer. It is covered by a narrow, elongated strip of wire-covered clothing wrapped helically around its periphery. The doffer is enveloped by straight wound card clothing, preferably constituted of a rectangular segment of wire-covered clothing having its opposite ends abutting on the doffer. The invention maximizes utilization of the fiber transfer area available to the knitting machine. It enables the use of wider fiber transfer paths and/or the provision of an increased number of fiber transfer units about the circumference of the machine.
