Patent ID: 7124671

Claim:
A method for reducing breakage in a paper web when the web is moved into a web cutter from an upstream source, said method comprising the steps of providing a cutting mechanism for cutting the web into sheets, and providing a first moving mechanism for moving the web into the web cutter, wherein the first moving mechanism operates in a start-and-stop motion cycle, the motion cycle having a stop period to allow the cutting mechanism to cut a sheet from the web, 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, and a deceleration period during which the first moving mechanism decelerates from the predetermined velocity at a cutter deceleration to the stop period, said method comprising the steps of: disposing a second moving mechanism 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 into the web cutter via the loop, and operating the second moving mechanism 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.
