Plastic tubular film - rotary take-off and flattening equipment

摘要

Take-off appts. for tubular films of thermoplastic or similar materials, having a locally fixed extrusion press and wind-up appts., in which a space is provided between the reversing take-off, rotating through about 360 degrees, and the first fixed guide roll taking the film, e.g. to the wind-up; the spacing is a multiple - pref. 5-10 times - the film width, so that in this region the flattened film strip can rotate back-and forwards round its long axis through about plus-or-minus 180 degrees.
