Abstract
A high speed packaging machine for making pouches of fluent material has a transfer wheel that changes the orientation of the finished, individual pouches. The wheel has a plurality of holder shafts rotatably mounted in the transfer wheel. The holder shafts mount vacuum cups for holding a pouch. The holder shafts also have a pinion which is engaged by a gear which in turn is actuated by a cam follower. The cam follower engages a stationary cam and is constrained for movement within a cam path. The cam follower causes rotation of the gear, pinion and holder shaft. The cam follower can be connected to the gear in either a leading or lagging position so the direction of holder shaft rotation can be selected without altering the cam or cam path.
