ABSTRACT:
This invention is directed to an apparatus for stacking sheet-like articles (15) which are delivered by a conveyor to the upper portion of a stack compartment (18). The stack compartment (18) includes stop rails (19, 20, 21, 22) which define the edges of the stack. The sheet-like articles (15) on the section (12) of the conveyor are fed with one of the corners in front in a conveying direction (17) which forms an angle other than 0.degree. and 90.degree., preferably about 45.degree., with the side edges of the sheet-like articles (15) adjoining the corner so that the sheet-like articles strike against two stop rails (19, 20) which are mutually at right angles at the moment the sheet-like articles reach the stack compartment. Accordingly, the sheet-like articles will each be properly aligned by the two stop rails (19, 20) to form a neat, right-parallelepipedal stack.
