ABSTRACT:
A film or web stretcher particularly for thermoplastic film has a plurality of stretching cylinders, at least one or more of which cooperate with a press-on roller particularly at the inlet and/or outlet of the stretcher. A mounting arm (6) at each end of the stretcher cylinder permits the mounting of the press-on roller in such a way that the latter can be tilted through a limited angular range about the rotational axis of the stretching cylinder by a first drive. A second drive, such as a piston cylinder device adjusts the press-on roller relative to the stretching cylinder to thereby apply a press-on force. The first drive may, for example, be accomplished by a manually driven device for positioning the press-on roller and its cooperating components in any one of two end positions and in any position between the two end positions. The press-on roller may be directly mounted to the mounting arms (6) or through support brackets (9) to the arms (6).
