ABSTRACT:
A device for forming a stack of printed sheets. The device includes a conveying device for conveying the printed sheets in an imbricated flow vertically downwards and an approximately horizontal stack support disposed below the conveying device and having an entrance end for receiving the printed sheets. The stack support has a working region where stacks of the printed sheets are formed, and, disposed downstream of the working region in a stack formation direction, a pressing region where formed stacks of the printed sheets are compressed. The device also includes a guide arrangement disposed above the stack support and including two support mechanisms displaceably driven between the working region of the stack support and the pressing region of the stack support, such that, in the working region of the stack support, the support mechanisms serve as an insertion device for forming stacks by inserting an end plate at an end side of a stack of printed sheets, and, in the pressing region of the stack support, the support mechanisms serve as a jaw-type press for compressing a formed stack. The support mechanisms are further effective for conveying a formed stack from the working region of the stack support to the pressing region of the stack support. The device further includes a tying device operatively associated with the support mechanisms and disposed adjacent the pressing region of the stack support for tying a formed stack.
