Abstract

L'invention concerne un dispositif servant à guider et à transporter plusieurs fils en plusieurs points de distribution adjacents d'une machine textile. En chaque point de distribution, un dispositif distributeur d'enlacement (3) est formé par une enveloppe de galette entraînée (15.1) et par un rouleau de repère tournant librement (16.1) associé à l'enveloppe de galette, l'enveloppe de galette et le rouleau de repère étant plusieurs fois enlacés par le fil (30) associé au point de distribution. Pour entraîner les dispositifs distributeurs d'enlacement, les enveloppes de galette d'un groupe de points de distribution voisins ou les enveloppes de galette de tous les points de distribution sont reliées à un moyen d'entraînement et sont entraînées de manière synchrone pour le transport des fils. Pour pouvoir entraîner chacune des enveloppes de galette à des vitesses périphériques pratiquement identiques, le moyen d'entraînement est formé par un arbre d'entraînement (17) à la circonférence duquel les enveloppes de galette sont fixées à distance les unes des autres de manière solidaire en rotation.
