ABSTRACT:
An apparatus for forming a fiber lap to be processed by a carding machine includes a generally vertically oriented feed chute having generally parallel and vertically oriented front and rear walls. The chute has an opening at the top for receiving fiber tufts and an opening at the bottom for delivering a fiber lap. An air stream is introduced into the chute for flow in the direction of the bottom thereof. Air exit openings are provided in the zone of at least one of the walls allowing the air stream to leave the feed chute. The depth of the feed chute measured horizontally at the height level of the air exit openings varies along the chute width, whereby a fiber lap of varying thickness along the lap width is produced.
