ABSTRACT:
During the gathering process, an individual signature is respectively withdrawn from several collections of identical signatures, wherein the various decollated signatures are delivered to a collecting conveyor in order to form stacks. In this case, the sheets need to be reliably and carefully decollated. The invention proposes that the sheets (3) of a collection are made available in the form of a stack (4), wherein the stack (4) is essentially supported by an air cushion (LP), that the bottom sheet (3) is at least regionally lifted off the stack (4) with the aid of a separating tool (30), that the air cushion (LP) is produced between the bottom sheet (3) and the residual stack (4), and that the sheet (3) is delivered to the collecting conveyor (10). The lifted-off sheet is completely separated from the stack by the air cushion such that the sheet can be transported out of the magazine with absolutely no friction relative to the stack (4) situated above the separated sheet.
