    摘要： A method and apparatus for moving along a tube extrusion line. An extruded tube is pushed through the extrusion line, by means of pressure generated by an extruder, to a withdrawal unit that takes over further driving of the tube. In a first-moving along phase, in which the tube has not yet passed a sealing of a calibration cooling unit relative to the atmosphere, the latter is under atmospheric pressure. In a second phase, in which the tube has passed the sealing, the calibration and cooling unit is placed under underpressure. In the first phase, the tube is supported either by internal overpressure or by a mechanical inner guide. A support cylinder extends axially from a casing head of the extruder and extends coaxially into a calibration sleeve in a first section of the calibration and cooling unit. A support plate is disposed between the casing head and an inlet of the calibration sleeve and provides external support for a tube exiting the casing head.

    摘要： A calibration device for calibrating an extruded film tube, above the frost line, forms an annular gap between the calibration device and the film tube. The calibration device includes a plurality of calibration segments and at least one blowing nozzle. The plurality of calibration segments are distributed around a longitudinal axis and form a central feed through opening for feeding through the film tube along the longitudinal axis. The calibration segments are adjustable for adjusting the diameter of the feed through opening. The at least one blowing nozzle for each calibration segment, feeds a calibration gas to the feed through opening. The at least one blowing nozzle is formed such, that the calibration gas is guided to the annular gap substantially parallel to a surface of the film tube and that the calibration gas flows through the annular gap in a single flow direction.

    摘要： A tube support mechanism is adaptable to a respective tube diameter being transported, and includes an articulated link chain that rests against a circumference of a tube, and includes chain links. The chain links are disposed in at least two planes, overlap one another from plane to plane in overlap zones, and are pivotably connected. Facing ends of the chain links of a given plane of chain links have identical gear wheel contours that mesh with one another. Adjustment of the tube support mechanism from one nominal diameter to another is effected by a pressure effect, onto the tube support mechanism, of a conical tube transition piece that results during the change in diameter during continuing operation. An angle of contact of the tube support mechanism against a tube successively changes.

    摘要： A polyetheretherketone pipe of length greater than 250 meters and a residual stress of less than 5 MPa may be made using a calibrator device (2) which includes a cone shaped opening (6) arranged to receive a molten extruded pipe shaped polymer. Attached to the front member (4) is a vacuum plate (14a) and successive vacuum plates (14b-14h) are attached to one another to define an array of vacuum plates, the vacuum plates being arranged to allow a vacuum to be applied to a pipe precursor passing through opening (16). The vacuum plates (14) also include (10) temperature control means for heating or cooling the plates and therefore heating or cooling a pipe precursor passing through the openings. With a vacuum applied to opening (6, 16) and heating/cooling the plates, an extruded hot plastics pipe is inserted into calibrator (2) via opening (6) and conveyed through opening (16) in plates (14), whereupon it is urged by the vacuum against the cylindrical surface defined by plates (14) to maintain its shape and the (15) temperature of each plate is controlled to control the rate of cooling of the pipe precursor passing through. The pipe may be cooled at a relatively slow rate so that a pipe made from a relatively fast crystallising polymer crystalises and the crystallinity of the pipe along its extent and throughout its thickness is substantially constant.
