CA 2428243
An apparatus and process for continuously and endlessly vulcanizing a hose is disclosed and claimed. Pressurized air or other gas is intermittently supplied through a woven jacket (101), a mandrel (104, 105), a check valve (106) and into the interior of an extruded rubber hose. The hose is sealed as it is pulled over the mandrel. Pinch rollers (143) seal the other end of the hose. One or more non-contact heaters (126, 129) vulcanize the hose from outside-in. Pressurizing the inside of the hose maintains proper diametrical dimensions of the hose.
L'invention porte sur un appareil et un procédé de vulcanisation continue et illimitée d'un tuyau. De l'air pressurisé et d'autres gaz sont envoyés, par intermittence, à travers un manchon tissé (101), un mandrin (104, 105), un clapet (106) et à l'intérieur d'un tuyau en caoutchouc extrudé. Le tuyau est scellé lorsqu'il est enroulé autour du mandrin. Des galets pinceurs (143) scellent l'autre extrémité du tuyau. Un ou plusieurs dispositifs de chauffage (126, 129) sans contact vulcanisent le tuyau de l'extérieur vers l'intérieur. La pressurisation de l'intérieur du tuyau permet de conserver des dimensions de diamètre du tuyau appropriées.
