Apparatus for stacking signatures.

摘要

First and second longitudinal extending signature support elements has longitudinal axes extending transversely to a vertical plane. First drive unit moves the first signature support elements along a first circuitous path, the second drive unit for move the second signature support elements along a second circuitous path which is separate from the first circuitous path. The first and second drive unit are disposed on a first side of the vertical plane. Each signature support element of the first and second of signature support elements extends through the vertical plane, and has surface for engaging a lower side of a stack of signatures to support the stack of signatures with the stack of signatures entirely disposed on the second side of the vertical plane. A jogger is disposed on the second side of the vertical plane for jogging the stack of signatures.
