Abstract
A take-away device for a plastic tubing produced in a blowing process in which the tubing is flattened by squeeze rollers followed by a pair of take-away rollers. The pair of take-away rollers which have horizontal axes of rotation swivel reversingly about a vertical axis of rotation. The flattened tubing is fed to a stationary wind-up device, whereby two turning rods over which the flattened tubing is guided, are arranged between the take-away rollers and the stationary wind-up device, and swivel reversingly about the vertical axis of rotation of the pair of squeeze rollers. The first turning rod can thereby be swivelled about a first vertical axis which, together with the take-away rollers, swivels about the vertical axis of rotation of the pair of take-away rollers. The second turning rod can be turned about a second vertical axis which forms a plane with the vertical axis of rotation of the pair of take-away rollers, which extends parallel to the direction of travel of the tubing from the second turning rod to the wind-up device.
