ABSTRACT:
In the production of thin film that is extruded onto a cooling roller and then fed through a further treatment station such as stretching roller station, it may become necessary to stop the extrusion if a fault is present in the further treatment station. In order to avoid stopping the extrusion, a detour station with a roller set is positioned between the extrusion station and the further treatment station for detouring extruded film in response to a detected fault in any system component, except the extruder, whereby the extrusion can continue while the film is supplied to some other use while its supply to the further treatment station is interrupted. The detouring roller set includes at least one guide roller and a press-on roller that is automatically movable, for example by a piston cylinder device into a working position in response to a fault signal. When the fault signal is no longer present, the press-on roller is moved into a rest position for a continued supply of the extruded film into the further treatment station.
