Abstract
To form a composite random fiber web containing long and short length fibers, the two types of fibers are fed simultaneously into the same lickerin but with the shorter fibers fed into the lickerin above the longer length fibers, that is, at a point spaced angularly in the direction of rotation of the lickerin in advance of the point at which the longer fibers are fed into the lickerin. The intermingled fibers are doffed from the lickerin by centrifugal force due to the high speed rotation of the lickerin and by an air stream traveling past the lickerin, and are conveyed by the air stream to a moving foraminate condenser on which they are laid down in random fashion. In one embodiment of the invention, two lickerins are provided and two sheets of short length wood pulp fibers are fed into each lickerin angularly in advance of but simultaneously with feed of a mat of longer length textile fibers into each lickerin. A divided air stream sweeps past the two lickerins to doff the fibers therefrom.
