Title
(EN) A DEVICE FOR FEEDING A YARN TO A TEXTILE MACHINE HAVING A YARN-CUTTING DEVICE
(FR) DISPOSITIF POUR DÉLIVRER UN FIL À UNE MACHINE TEXTILE AYANT UN DISPOSITIF DE COUPE DE FIL
Abstract
(EN)
A device (1) for feeding a yarn (F) to a textile machine (T) comprises a housing (1A) with which a rotary member (2) is associated to cooperate with the yarn (F) unwinding from a package and directed, on leaving the device (1), to said machine (T) where it is processed, correct feed of the yarn (F) being monitored by feed control means (5) associated with said housing (1A) in accordance with at least one measured parameter related to the rotary member (2) or to an intrinsic characteristic of the yarn (F) such as its tension or its feed velocity, a yarn cutting member (13) being provided. This is connected to and controlled by said control means (5) on the basis of the measured parameter of the yarn (F), said cutting member (13) being activated by said control means (5) to cut the yarn (F) whenever the parameter monitored by said means has a value exceeding a predetermined required value.
(FR)
L'invention porte sur un dispositif (1) pour délivrer un fil (F) à une machine textile (T), lequel dispositif comprend un boîtier (1A) auquel est associé un élément rotatif (2) pour coopérer avec le fil (F) se déroulant à partir d'un paquet, et dirigé, lorsqu'il quitte le dispositif, vers ladite machine (T) où il est traité, une avance correcte du fil (F) étant régulée par des moyens de commande d'avance (5) associés audit boîtier (1A) en fonction d'au moins un paramètre mesuré associé à l'élément rotatif (2) ou d'une caractéristique intrinsèque du fil (F), telle que sa tension ou sa vitesse d'avance, et un élément de coupe de fil (13) étant disposé. Celui-ci est relié auxdits moyens de commande (5) et est commandé par ceux-ci sur la base du paramètre mesuré du fil (F), ledit élément de coupe (13) étant actionné par lesdits moyens de commande (5) pour couper le fil (F) à chaque fois que le paramètre contrôlé par lesdits moyens a une valeur dépassant une valeur requise prédéterminée.
