Abstract

There is disclosed a device for guiding and spreading out a moving material web, which includes a spreading station, a guide station and at least one edge-sensing system downstream from the guide station. The spreading station is arranged downstream from the guide station, so that very high web speeds can be realized because the web corrections are executed very gently and without whipping up the correcting pulses.
