ABSTRACT:
A stacker assembly receives signatures and supports the signatures as an intermediate stack is formed. A jogger assembly engages an intermediate stack supported by the stacker assembly to accurately align edge portions of the signatures. The stacks of signatures are deposited onto a turntable to form a main stack. The turntable rotates the main stack to offset relatively thick folded edge portions of signatures. The stacker assembly includes a plurality of slats which are moved along a first continuous circuitous path by a first drive assembly. The stacker assembly also includes a plurality of slats which are moved along a second continuous circuitous path by a second drive assembly. The drive assemblies move the slats along the continuous circuitous paths with the longitudinal axes of the slats horizontal and parallel. The jogger assembly has jogger plates which extend into central portions of the continuous circuitous paths along which the slats are moved by the drive assemblies.
