Abstract: A machine for conditioning a stack of pads, such as sanitary pads, for packaging includes a rotor. Radially extending chambers having closed sides and open front and rear ends are fastened to the rotor. There is a compressor plunger in each chamber. The plungers are carried on guide rods extending from cam follower brackets. A stationary cam plate is mounted perpendicular to the rotational axis of the rotor. The follower rollers are spring biased into contact with the periphery of the cam plate. The chambers are incremented in angular steps starting with a position in which the chamber is stopped momentarily for being loaded with a stack of pads at which time its plunger is retracted. As the loaded chamber increments in two angular steps to an unloading position, the plunger is driven out by the cam to compress the stack. When the chamber rotates from loading position to unloading position, the pads are effectively turned so they are standing on their edges in the unloading position.
