ABSTRACT:
A stack (S) of sheets is formed on a downwardly moving platform (4), the stack being divided into portions (P) each consisting of a predetermined number of sheets. As each alternate portion is completed, that portion is gripped between two plates (5, 20) and moved horizontally so that it is offset relative to the portion next below it.
A completed stack containing the required number of portions is separated from the rest of the stack by inserting a divider (40) at the desired position. The platform (4) is then moved to remove those portions below the divider and, at the same time, an auxiliary support (41) moves beneath the divider (40) to support the stack above. The completed stack is removed from the platform (4) which is then raised level with the support (41). The divider (40), support (41) and platform (4) move together so that the stack is again supported on the platform (4).
