Method and device for reducing web breakage in a web cutter

A web cutting system for moving a web of paper from an upstream paper source and for cutting the web into sheets, said web cutting system comprising:

• a cutting mechanism;
• a first moving mechanism, positioned upstream from the cutting mechanism, for moving the web of paper past the cutting mechanism, wherein the first moving mechanism operates in a start-and-stop motion cycle, the stop-and-start motion cycle having
• a stop period to allow the cutting mechanism to cut a length of the leading portion,
• an acceleration period during which the first moving mechanism accelerates from a stationary state to a predetermined velocity at a cutter acceleration in order to move a length of the web downstream from the cutting mechanism for cutting;
• a deceleration period during which the first moving mechanism decelerates from the predetermined velocity at a cutter deceleration to the stop period;
• a second moving mechanism positioned upstream from the first moving mechanism for moving the web toward the first moving mechanism to form a loop of paper upstream from the first moving mechanism so as to allow the first moving mechanism to move the web via the loop, wherein the second moving mechanism operates in a further motion cycle in coordination with the start-and-stop motion cycle, the further motion cycle having a second acceleration less than the cutter acceleration and a second deceleration less than the cutter deceleration, and
• a third moving mechanism positioned upstream from the second moving mechanism for moving the web toward the second moving mechanism, such that a further loop of paper is formed between the second moving mechanism and the third moving mechanism so as to allow the second moving mechanism to move the web toward the first moving mechanism via the further loop.
