  • Patent number: 4836744
    Abstract: A take-away device for a flattened tubing foil forming machine having an improved foil edge position control. The take-away device for tubing foil is formed by an extruder with a tubing blow head carrying out a blowing process. The tubing foil is flattened between a pair of squeeze rollers, which pair of rollers can reversingly turn about a vertical axis of rotation. At least two turning rods are disposed following the squeeze rollers. The turning rods are pivotable about at least one vertical axis, and have, if necessary, at least one deflecting rod. The rods are pivoted by a frame member about a horizontal axis of rotation. A winding-up device receives the flattened tubing foil from the turning rod. A measuring instrument is disposed between the final turning rod from which the tubing foil is guided to the wind-up device, and the wind-up device.
