ABSTRACT:
A pneumatic sheet feeder for removing individual sheets from a stack comprises a table having a surface for supporting a stack of sheets. A pair of parallel guide rails are provided on the table and with facing surfaces so that the stack is confined between the guide rails for movement in a feed direction across the table. Blast nozzles are provided in the guide rails for blowing air against the stack to form an air cushion between lower sheets of the stack. A suction cylinder is rotatably mounted to the table and includes a suction chamber therein for receiving a vacuum. Radial openings in the suction chamber cause a suction induced adhesion of a leading edge of a lowermost feed in the stack so that with rotation of the cylinder, the lowermost feed is fed in the feed direction away from the rest of the stack. A single blower is provided with a pair of two-way solenoid valves and a switching circuit is provided for alternately activating the valves. The valves are connected to a single blower having a discharge line and a suction line so that by simply switching the valves over between two positions, the blast nozzles are provided with compressed air and the suction chamber is provided with a vacuum.
