Abstract

Ce tour multibroches est du type de ceux munis d'un tambour portant des broches équipées chacune de dispositifs de freinage et d'embrayage. Dans le tour selon l'invention un commutateur rotatif multipolaire est associé au tambour, dont il accompagne les déplacements angulaires successifs. Il comprend une partie fixe 27 et une partie rotative 21 portant des contacts respectifs 29, 22 qui coopèrent entre eux et font partie des circuits de commande des dispositifs de freinage et d'embrayage, et au moins deux bagues conductrices continues 50, 51 sur une 21 des parties, coopérant en permanence avec Certains des contacts de l'autre partie 27. Le choix d'une des positions possibles du commutateur établit simultanément la connexion entre un certain nombre des contacts 29 et 22. Des moyens sont prévus pour commander l'alimentation en courant des contacts et des bagues pour un actionnement sélectif des dispositifs d'embrayage et de freinage.
