ABSTRACT:
An improved tyer includes a central station where loose stacks of signatures sre received. A pair of tying stations are disposed on opposite sides of the central station. A pair receiving stations are disposed adjacent to the tying stations. An improved shuttle assembly is used to sequentially move loose stacks of sheets from the central station to one or the other of the tying stations. The shuttle assembly includes three pusher arms which are movable along tracks between the central and tying stations. Gaps are provided in the tracks at the tying station to enable bands or straps to be moved through the tracks and secured around loose stacks of signatures at the tying stations. In order to provide for as compact a loose stack of signatures as possible at a tying station, the loose stack of signatures is compressed between a pair of pusher arms as it is moved to a tying station. In order to protect the bottom of a tied stack of signatures, a cover sheet is positioned between the bottom of the loose stack of signatures and a support surface as the loose stack of signatures is moved from the central station to a tying station.
