ABSTRACT:
The method of aligning successive stacks of sheets each having a lower portion and an upper portion off-set comprises horizontally feeding each stack with the offset edge of the upper portion leading towards a horizontally disposed sheet separating blade to a position at which the offset edge overhangs the blade. Relative vertical movement between the blade and the stack is effected until the blade has partly lifted the offset edge of the upper portion. Relative horizontal movement between the blade and the lower portion of the stack is next effected by pushers to cause penetration of the blade between the upper and lower portions followed by abutment with the offset edge to bring the upper portion into alignment with the lower portion.
