Patent ID: 8413792

Claim:
A method to produce stacks composed of printed products, comprising: supplying the printed products substantially vertically and in an overlapping flow with the aid of a first conveying device continuously to an essentially horizontally extending stack support; forming a stack at the stack support, wherein the printed products are at least approximately lined up in an upright position; transporting the stack on the stack support with a second conveying device moving at a forward-feed speed and in a forward-feed direction, wherein the stack is supported along a leading stack end against a support device that also moves in the forward-feed direction; and acting upon a region of a lower edge of at least one printed product in an area of impact of the printed product, which simultaneously impacts the stack support and the second conveying device, using a third conveying device to move the lower edge of the at least one printed product in the forward-feed direction of the stack with a speed that corresponds at least to the forward-feed speed of the stack to thereby create a space between two lower edges of successively following printed products.
