Abstract: A PIPE IS CONTINUOUSLY FORMED BY SPIRALLY WINDING A BAND ONTO THE CYLINDRICAL PORTION OF A MANDREL AFTER THE BAND EXITS FROM A SYNTHETIC MATERIAL EXTRUDING MACHINE WHILE STILL THERMOELASTIC OR AFTER A PREFORMED BAND IS PASSED THROUGH THE SUITABLE HEATING DEVICE. ONE LONGITUDINAL EDGE OF THE BAND IS PROVIDED WITH A RADIALLY OUTWARDLY WIDENING TONGUE AND THE OTHER LONGITUDINAL EDGE OF THE BAND IS PROVIDED WITH A RADIALLY INWARDLY WIDENING CHANNEL. IN FORMING THE PIPE, THE TONGUE IS COOLED TO BE RIGID AND INSERTED INTO THE THERMOELASTICALLY HEATED CHANNEL OF AN ADJACENT LAP OF THE SPIRALLY WOUND BAND.

Abstract: An apparatus and method for the continuous production of wound pipes from an extruded profiled strip. In order to compensate for deviations in the speed of the strip being supplied by an extruder, a control mechanism for controlling the speed of the wind-up drum in dependence on the magnitude of the sag in the profiled strip at a position intermediate the extruder and windup drum is provided. To further accommodate any deviations in a cross-sectional size of the profiled strip, a cooled sizing shoe is provided for shaping the outer contours of the pipe formed by the connected-together, spirally wound extruded strips. In order to cut the completed pipe in a single plane perpendicular to the axis of the pipe, without circumferentially moving the cutting apparatus, and while maintaining the winding mandrel continuously rotating, a cutting mechanism control means is provided which axially moves the cutting mechanism at the same speed as the axial movement of the completed pipe along the mandrel.

Abstract: THE PRESENT DISCLOSURE IS DIRECTED TO A SHAPED SECTION OF A THEMOPLASTIC SYNTHETIC MATERIAL CONTAINING AT LEAST ONE TONGUE PORTION AND AT LEAST ONE GROOVE PORTION FOR MUTUAL JOINING OR FOR FURTHER JOINING SAID SECTION WITH SIMILARLY SHAPED SECTIONS CONTAINING IDENTICAL TONGUE AND GROOVE PORTIONS WHEREIN THE CROSS-SECTIONAL CONFIGURATIONS OF

SAID TONGUE AND GROOVE PORTIONS ARE ADAPTED TO EACH OTHER SUCH THAT UPON INTERLOCKING WITH EACH OTHER, THEY ARE DEFORMED AND PRESSED TOGETHER IN A FLUSH UNION ALONG THEIR ENTIRE SURFACE.
