Abstract (en)
[origin: US4864693A] A textile fiber preparation feed system and method are disclosed in which processed textile fibers from a blender (A) are delivered to a flow-through textile cleaner (B) and then directed to a vertical chute feed (C). An air stream conveys the fibers from blender (A) to chute feed (C) across cleaning rollers (34, 36) of cleaner (B) without a nip feed providing increased cleaning efficiency. Control system (60) continues operation of top feed roll (52) after termination of carding machine (14) and discharge of fiber batt (12) from the chute feed to purge excess fibers in the air stream. In this manner, accumulation of the excess fibers in a fiber column (F) above top feed roll is prevented which would block air exit (50) and choke down top feed roll (52) upon resumption of the carding machine or fiber batt discharge.
