Patent ID: 6945530

Claim:
A device for conveying stacks of sheets of paper, said device comprising a pocket conveyor provided with a plurality of pockets, each of which has a resting surface for a corresponding said stack and is designed to feed the stack along a path that is substantially parallel to said resting surface, said device being characterized in that it comprises pressure means set along said path for gripping each of said stacks on said resting surface during at least part of the displacement of said stack along the path, first actuator means for displacing said pressure means from a gripping position for gripping each stack on the resting surface during displacement of the stack along said path to a released position for releasing each stack, and second actuator means designed for displacing said pressure means from the released position to the gripping position, said first actuator means comprising elastic thrust means designed to maintain the pressure means normally in said released position and said second actuator means comprising cam means designed to displace the pressure means into said gripping position against the action of said elastic thrust means.
