ABSTRACT:
Each card is interconnected to a multiplicity of pneumatic feed ducts via a branch duct which can be selectively placed in communication with any one of the feed ducts. Each branch duct includes a plurality of openings near one end, each of which is opened or closed relative to a feed duct by means of a sliding baffle. In addition, the upstream end of each branch duct is open to the atmosphere so that the same constant air pressure prevails in all of the feed chutes to the various cards.
