Abstract
Method and apparatus for handling stacks of sheets, including a carrier for lowering the sheets in a stacker and having a clamp which applies to the bundle and moves therewith throughout the lowering process. The clamp is mounted on the carrier for movement into and out of clamping position, and in the clamping position it permits the bundles to be lowered without bending or distorting the sheets which are otherwise dragging on a stationary support.
