ABSTRACT:
Apparatus for flattening and removing tubular plastic film has squeeze rollers, a radial arm with a deflecting roller and a shorter radial arm with a fixed turning rod. The film from the squeeze rollers passes by way of the deflecting roller and turning rod to a winder. The deflecting roller can be swung through 180 degrees while the turning rod is swung through 90 degrees. The turning rod is mounted for swinging movement in a recess in a U-shaped frame and the deflecting roller and squeeze rollers are mounted for swinging movement on one of the legs of the frame. The arrangement allows the size of the turning rod to be maximized.
