Abstract

Fabrication des tuyaux en matière élastomère Pour vulcaniser le tuyau sous pression et en continu, on enroule une bande de nylon ou équivalent N qui se rétracte à la chaleur sur le tuyau sortant d'une extrudeuse 7, renforcé par des fils longitudinaux fournis par une bobine 8 puis par un fil enroulé en hélice et finalement revêtu d'une feuille d'élastomère 6 enroulée en hélice. Dans un vulcanisateur 10, le tuyau est comprimé extérieurement par le retrait de la bande de nylon N et par un étranglement de la lumière de la chambre du vulcanisateur. La bande de nylon a également l'avantage de réduire le frottement du tuyau dans le vulcanisateur. A la sortie du vulcanisateur, le tuyau est débarrassé de son bandage de nylon par une dérouleuse de bandage 12. Application notamment à la fabrication des tuyaux en caoutchouc munis d'un renforcement textileManufacture of elastomeric material pipes To vulcanize the pipe under pressure and continuously, a nylon strip or N equivalent is wound which shrinks by heat on the pipe leaving an extruder 7, reinforced by longitudinal threads supplied by a coil 8 then by a wire wound in a helix and finally coated with a sheet of elastomer 6 wound in a helix. In a vulcanizer 10, the hose is compressed externally by removing the nylon band N and by restricting the lumen of the vulcanizer chamber. The nylon tape also has the advantage of reducing the friction of the pipe in the vulcanizer. On leaving the vulcanizer, the pipe is stripped of its nylon tire by a tire unwinder 12. Application in particular to the manufacture of rubber pipes provided with a textile reinforcement.
