Abstract

Lors du calibrage et de la stabilisation de la décharge d'un produit par des extrudeuses, on fait communément appel à des unités de calibrage tubulaires tant pour le calibrage du diamètre du produit que pour le refroidissement de celui-ci en vue de sa stabilisation initiale, le tuyau de calibrage devant posséder une certaine longueur. Il peut être souhaitable, lors d'un processus de calibrage précis, d'apporter de légères modifications au diamètre de calibration, ce qui entraîne toutefois des problèmes dans le changement du tuyau de calibrage. La présente invention concerne un tuyau de calibrage (14) à diamètre ajustable, le tuyau étant fait d'un certain nombre d'anneaux à fentes (16) juxtaposés dont les fentes (18) sont disposées de manière aléatoire, de sorte que lorsque l'on regarde le tuyau dans sa direction axiale, celui-ci semble être complètement ininterrompu. Les anneaux (16) peuvent être comprimés radialement et collectivement de manière commandée par l'intermédiaire de barres axiales de calage et de serrage (24, 26), ce qui permet d'obtenir un ajustement uniforme du diamètre du tuyau dans son ensemble.
