Abstract
The invention provides an apparatus and method for feeding, bundling and transporting a stream of sheets, such as printed sheets in signature form. A vertical stacking machine stacks a stream of signatures and then clamps, compresses and straps the signatures into a bundle for transportation and delivery. The machine has a pair of improved bar clamps for preventing sheet drift during compression and strapping. The clamps attach each bar to a driving mechanism in a cantilevered fashion. Each bar is only attached to the driving mechanism at the top and/or the center portion of the bar. The opposite, bottom end of each bar is free of attachment to the driving mechanism. As a result, a critical obstruction is removed.
