Abstract

Extrusion equipment for the production of plastic tubes, and more particularly for the production of flexible, internally reinforced plastic tubes, of the type comprising a tube extruder for the extrusion of a blown inner tubular, a device for winding band to reinforce said tubular and a second tube extruder for coating said tubular, which has been wound band, with some plastic material, characterized in that a support is provided, inside the tubular being extracted, and that is supported in cantilever by the extrusion screw of the first tube extruder, some axial and radial conduits located in said support for the passage of the appropriate compressed air to maintain an air cushion between the support and the inner wall of the tubular, a second free support radially inside the extruder coating the tube and kept axially centered by the same tube that has been wound band, finally providing flexible articulation means between said first rigid support and said second mobile support to prevent axial displacements of the latter during extrusion.
