Abstract: A method for producing stacks of printed sheets, including supplying the printed sheets along a conveyor, stacking the printed sheets along the stack support in an upright position, supporting the first stack via a supporting device, transferring the first stack from the supporting device to a compression device having first and second compression carriages, compressing the first stack between the first and second compression carriages, strapping the first stack, releasing and moving the first compression carriage towards a second stack subsequently formed, and transferring support for the second stack from the supporting device to the first compression carriage.

Abstract: An apparatus for forming partial stacks by separation of a stack of printed sheets standing one behind the other includes an approximately horizontal stack guide having a feed end for receiving printed sheets fed in a direction perpendicular to the stack guide from a feeding apparatus and stacking the printed sheets on edge to form a stack in a horizontal direction. A separating device is arranged along the horizontal stack guide for forming the partial stacks. The separating device includes a guide arrangement disposed parallel to the horizontal direction of stack forming. First and second components of the separating device are seated one behind the other on the guide arrangement and are displaceable along the guide arrangement. The first and second components are jointly displaceable to the feed end of the stack guide and are controllable to be separable from one another in a stack separating position. Spreading elements are pivotally connected to the first and second components of the separating device.
