Title (EN) YARN FEEDING DEVICE
(FR) DISPOSITIF D'ALIMENTATION EN FIL
Abstract:
(EN) A yarn feeding device (1) comprises a stationary storage drum (2) from which the yarn can be withdrawn. In accordance with the present invention, the yarn feeding device can be operated at a positive feeding mode and at a non-positive feeding mode by means of a rotatable yarn guiding member (7) arranged at the withdrawal end (5). The yarn guiding member (7) comprises at least one yarn engagement element (11) adapted for engaging the yarn when the rotational speed of the yarn spiralling around the withdrawal end of the storage drum tends to exceed the rotational speed of the yarn guiding member (7). The yarn engagement element (11) comes out of engagement with the yarn when the rotational speed of the guiding member (7) exceeds the rotational speed of the yarn spiralling around the withdrawal end (5) of the storage drum (2).
(FR) Le dispositif ci-décrit (1) comprend un tambour de stockage fixe (2) à partir duquel le fil peut être prélevé. Le dispositif d'alimentation en fil peut être utilisé en mode d'alimentation positif et en mode d'alimentation non positif à l'aide d'un organe de guidage (7) de fil rotatif disposé à l'extrémité de prélèvement (5). L'organe de guidage (7) de fil comprend au moins un élément d'engagement (11) de fil permettant d'engager le fil lorsque la vitesse de rotation du fil s'enroulant en spirale autour de l'extrémité de prélèvement du tambour de stockage tend à excéder la vitesse de rotation de l'organe de guidage (7) du fil. L'élément d'engagement (11) de fil est désolidarisé du fil lorsque la vitesse de rotation de l'organe de guidage (7) excède la vitesse de rotation du fil s'enroulant en spirale autour de l'extrémité de prélèvement (5) du tambour de stockage (2).
