<p>Apparatus for forming a stack of sheets from a succession of sheets, in which the stack is formed of portions (P) each containing the desired number of sheets and the portions are displaced horizontally in the stack (S) in relation to adjacent portions to facilitate later handling and processing of the portions. Alternate portions of the stack may be in vertical alignement or the horizontal displacement may be only in one direction so that the stack simulates a night of steps. The displacement may be produced by supporting the top part of the stack and displacing the part (P1) of the stack below the support, the operation being repeated each time the support moves up one portion, or by forming each portion at a position displaced from the portion below it. </p> |
