  • Gripper apparatus for stacking a batch of sheets
    Patent number: 4673325

A roller stop at the bottom of the sheet support engages behind one side of the batch and at least one clamp is movable to grip the batch against the support between that clamp and the stop. Tilting members at the bottom of the support are operable, when the support is in a substantially vertical position, to lift the batch over the roller stop as it is stacked.
