Definitions

  • the present invention relates to a plastic band for the production of pipes in the winding process by connecting the band edges along a helical seam.
  • the object of the present invention is now to design a plastic strip with regard to its use for forming a winding tube in such a way that even with small wall thicknesses there is sufficient strength and, in particular, rigidity and, in addition, gas tightness which is substantially improved compared to conventional plastic tubes can be achieved.
  • the reinforcing sheet with the exception of the edge parts on both sides lying in the band closure zone, is preferably embedded in the band base body made of plastic.
  • the reinforcing sheet should preferably protrude or be exposed laterally to such an extent that at least a part of the closure contact surfaces of the band lying in the band plane can be covered with it.
  • Another possibility is to place the reinforcement sheet directly on a belt surface, e.g. to be arranged on the underside of the plastic band intended to form the inner tube wall, e.g. by sticking.
  • the reinforcing metal sheet is preferably made of aluminum.
  • FIG. 1 shows a cross section through a plastic band designed according to the invention
  • Fig. 2 shows a variant of the band of Fig. 1
  • a plastic tape 1 with a reinforcing layer 2 in the form e.g. an aluminum sheet or strip is provided, the reinforcement layer 2a, 2b of metal being exposed on both sides of the band 1.
  • a left-hand band edge la comes to lie over a right-hand band edge 1b and forms a mechanical closure there (possibly additionally glued or welded) along the helical seam.
  • the exposed edges 2a, 2b of the reinforcing layer are welded at the locations A, A '(FIG. 1), C, C (FIG. 2), D, D f (FIG. 3) and E, E' (FIG. ).
  • the reinforcement layer 2 is not embedded in the plastic body 1, as in the previous embodiments, but is glued to a band surface.
  • the free areas 2a, 2b of the reinforcement layer 2 lie in the plane of the layer 2 itself. In this variant, welding is particularly easy to carry out.

Abstract

Une bande en plastique (1) comprend une couche de renforcement métallique (2) de préférence encastrée dans son corps de base et dont les sections marginales latérales (2a, 2b) font librement saillie sur le corps de base (1) de façon à se chevaucher lorsque le tube est enroulé et à pouvoir éventuellement être soudées ou brasées ensemble. Cette bande sert à fabriquer des tubes dits enroulés de haute résistance et ayant une imperméabilité améliorée aux gaz.
