Description

Tuyau souple en matière synthétique, par exemple tube d'aération, comportant un renforcement par fil en forme de spirale.
La présente invention a pour objet un tuyau souple en matière synthétique comportant un renforcement par fil en forme de spirale. Les tuyaux en matière synthétique de ce genre sont utilisés, par exemple, pour la ventilation,
<Desc/Clms Page number 2>
notamment dans les exploitations minières souterraines, sous la forme de tubes dits d'aération.
Dans ces tubes en matière plastique, il s'agit de tubes présentant un renforcement par fil qui est enroulé en forme d'hélice autour de l'enveloppe extérieure du tube et est fixé à cette enveloppe, La fixation de la spirale de fil sur le tuyau en matière synthétique s'effectuait jusqu'à présent de la manière qu'une gaine en.matière synthétique ouverte et correspondante à la section du fil était enfilée sur la spirale de fil, les bords de cette gaine étant soudés ou collés au tuyau en matière synthétique.
L'invention vise à résoudre le problème consistant à simplifier et à rendre moins coûteuse cette opération de travail. L'invention réside dans le fait que la spirale de fil est fabriquée à partir d'un fil enveloppé de matière synthétique et est fixée avec son enveloppe sur le tuyau par soudure ou collage. De cette façon, la spirale enveloppée de matière synthétique peut être directement posée d'une manière beaucoup plus simple sur le tuyau en matière synthétique par soudure ou collage.
La gaine en matière synthétique de la spirale de fil peut être fabriquée, par exemple, par immersion ou par application à la presse.
Une forme de réalisation du tuyau en matière synthétique est-.représentée en coupe, à titre d'exemple non limitatif, au dessin annexé.
<Desc/Clms Page number 3>
La spirale de fil 1 formée par un fil plat de section rectangulaire, enroulé en spirale sur le grand côté, est 'revêtue d'une gaine 2 en matière synthétique et est soudée avec cette dernière sur le tuyau en matière synthétique 3.

Flexible hose made of synthetic material, for example aeration tube, with a spiral-shaped wire reinforcement.
The present invention relates to a flexible pipe made of synthetic material comprising a reinforcement by wire in the form of a spiral. Synthetic pipes of this kind are used, for example, for ventilation,
<Desc / Clms Page number 2>
especially in underground mining operations, in the form of so-called aeration tubes.
In these plastic tubes, they are tubes having a reinforcement by wire which is wound in the form of a helix around the outer casing of the tube and is fixed to this casing, The fixing of the wire spiral on the Until now, the synthetic material hose has been carried out in such a way that an open synthetic material sheath corresponding to the cross section of the wire was threaded over the wire spiral, the edges of this sheath being welded or glued to the pipe in synthetic material.
The invention aims to solve the problem of simplifying and making this working operation less expensive. The invention resides in the fact that the wire spiral is made from a wire wrapped in synthetic material and is fixed with its casing on the pipe by welding or gluing. In this way, the spiral wrapped in synthetic material can be directly placed in a much simpler way on the synthetic material pipe by welding or gluing.
The synthetic sheath of the wire spiral can be made, for example, by dipping or by press application.
An embodiment of the synthetic material pipe is-.represented in section, by way of non-limiting example, in the accompanying drawing.
<Desc / Clms Page number 3>
The wire spiral 1 formed by a flat wire of rectangular cross-section, spirally wound on the long side, is covered with a sheath 2 of synthetic material and is welded with the latter on the plastic pipe 3.
