Abstract
A stack of signatures are dropped upon the platform halves of a rotatable platform, the platform halves being raised to reduce the free fall distance from the point where the stack of signatures are dropped and a lower stack ejection position. The platform halves are lowered as each stack of signatures is delivered thereto. Eventually, the platform is lowered to the stack ejection position and the pusher is pushed through a gap provided between the platform halves to eject a completed bundle from the platform. The pusher moves through the gap as the platform is being raised or lowered to significantly reduce the cycle time. Stack compressors are selectively movable to a position above the turntable and by selectively raising the platform halves, the accumulated stack of signatures on the platform halves are squeezed between the compression members and the platform halves to form a neat, compressed bundle. The turntable is rotatable through a half-revolution to form compensated stacks. The pusher may be returned to a start position while the platform halves are being raised without fear of collision due to the provision of the gap between the platform halves.
