Abstract
A squaring and aligning assembly for the transfer frame of a corrugated sheet stacking and feeding apparatus is mounted within a transverse guide member in the form of an elongated channel. Separate squaring shoes at each side of the machine are selectively moved along the channel. They can be connected in centered positions along opposite flights of a powered chain to center a block of sheets relative to the machine. One can be connected to a chain flight in an off-center position to align the block of sheets in an off-centered aligned condition. Either shoe can be clamped to the channel for edge alignment in response to movement of the remaining shoe.
