Abstract: Process for handling a material web that includes moving the material web along with at least one circulating endless belt in a circulation direction, monitoring movement of an edge of said at least one circulating endless belt, and monitoring a position of said at least one circulating endless belt in a transverse direction by way of at least one belt travel sensor. The at least one belt travel sensor has a belt engaging surface which engages the edge of the at least one circulating endless belt. The process further includes driving repeatedly the at least one circulating endless belt in a direction generally transverse to the circulation direction utilizing the at least one belt travel sensor to generate linear transverse movement of the at least one circulating endless belt.

Abstract: Process and device for handling a material web. The process includes moving the material web, at least in stretches, along with at least one circulating endless belt in a circulation direction and monitoring the movement of the edge of the at least one circulating endless belt. The process further includes driving repeatedly the circulating endless belt in a direction generally transverse to the circulation direction. The device includes at least one circulating endless belt for moving the material web along, at least in stretches, in a circular direction, and a master control unit for determining the transverse movement of the circulating endless belt. Additionally, the device includes at least one belt travel sensor for monitoring the position of the at least one circulating endless belt and repeatedly moving, in cooperation with the master control unit, the at least one circulating endless belt generally transverse to the circulation direction, and an activation device, for moving the sensor.
