Abstract
In the apparatus for binding stacks (31) of zig-zag-folded layers (40) a folder (10) is followed by a stacking device (43), which has a lifting table (14). In stacking area (41) following folder (10) is provided a separating device (24) in the form of a rake with front separating heads (100), which can be provided with blast air nozzles. A straightening device (22a) is used for periodically compressing the folded edge (82a) and the folder is preceded by a cutting mechanism (110) for making cuts on the folded edges (82a) to be separated, so that the separating devices (24) are not required to operate at areas on the edges provided with conveying holes.
