CROSSWISE PNEUMATIC CARD FEEDING SYSTEM

摘要

A pneumatic card feeding system including a vertical feed chute for each card defining an air tight vertical bin laterally coextensive with the card width for receiving fibers and delivering a batt to the feed end of the associated card, and a pneumatic overhead conveyor duct having a transverse width much smaller than the lateral dimension of the chute for conveying fibers by vehicle air from a supply source across the tops of a series of the chutes along a fiber feed path extending cross-wise of the cards. Multiple extractor rollers at the top of each chute mechanically transfer fibers from the air stream into the chutes.
