Abstract

A stacking device for a prefolded endless paper-web in a paper stacker, in which the paper-web is stacked on a paper support which is designed to move downward in accordance with the stack height, a compensating element being provided which moves downward with the paper support and is adapted to elevate the central portion of the stack, with respect to the folded edges thereof, to reduce the formation of a depression in such central portion resulting from the transversely folded edge portions, means being provided for varying the elevation height of the compensating element as a function of the stack height.
