Title
(EN) APPARATUS AND METHOD FOR CONTROLLING INTERNAL SIZE OF AN EXTRUDED HOSE
(FR) DISPOSITIF ET PROCEDE DE REGLAGE DE LA DIMENSION INTERNE D'UN TUYAU EXTRUDE
Abstract
(EN)
An apparatus and method for continuously extruding an elastomeric hose (10) having a controlled internal size. A controlled internal size is necessary in order to mount various types of couplings to the hose. Other hose making processes require extruding the hose on a mandrel in order to control the internal size. The use of mandrels restricts hose length and requires additional floor space due to the lengthy mandrels. An extruded hose (10) having a controlled internal size is continuously made by extruding an elastomeric material over a first end portion (104) of an internal shaping member (102) and continuously monitoring the flow of air between a gauge member (112) and the internal size of the hose (10). The rate of extrusion is controlled in response to the flow of air between the gauge member (112) and the internal size of the hose (10) changing from a predetermined range. The continuous monitoring of the internal size adjacent the internal shaping member and adjusting the rate of extrusion in response thereto produces a continuous hose with a controlled internal size without the use of long mandrels.

Dispositif et procédé permettant d'extruder en continu un tuyau élastomère (10) possédant une dimension interne régulée. Une dimension interne déterminée est nécessaire pour permettre de monter différents types de couplage sur le tuyau. Dans d'autres procédés de production de tuyaux il est nécessaire d'extruder le tuyau sur un mandrin afin d'en réguler la dimension interne. L'utilisation de mandrins limite la longueur du tuyau et augmente l'occupation au sol à cause de la longueur des mandrins. Un tuyau extrudé (10) possédant une dimension interne régulée est produit en continu en extrudant un matériau élastomère sur une première partie d'extrémité (104) d'un organe de façonnage interne (102) et en contrôlant en continu l'écoulement d'air entre un organe de jauge (112) et la dimension interne du tuyau (10). La vitesse d'extrusion est commandée en fonction de la variation par rapport à une plage prédéterminée de l'écoulement d'air entre l'organe de jauge (112) et la dimension interne du tuyau (10). Le contrôle en continu de la taille interne à proximité de l'organe de façonnage interne et la régulation de la vitesse d'extrusion en réponse au résultat de ce contrôle permettent de produire un tuyau continu possédant une dimension interne déterminée sans utiliser de longs mandrins.
