Title (EN) YARN HOOKING DEVICE IN A TWIN WINDER WITH AUTOMATIC TRANSFER
(FR) DISPOSITIF D"ACCROCHAGE DE FIL DANS UN BOBINOIR DOUBLE A TRANSFERT AUTOMATIQUE
Abstract: front page image
(EN)The hooking device comprises a movable rig (15, 16) which is coupled to a disc (2) driving the bobbin (1) and which may have an axial displacement. This rig is controlled by the jack (9, 10). It comprises a spout (18) which controls the hook (20) to which the inlet tail hooks during the transfer of the yarn at the start of the winding on the empty bobbin. After a few winding turns effected by the bobbin (1), the hook (20) is open by displacement of the movable rig in the axial direction in the position shown in chain-dotted. The initial tail of the yarn disengages from and takes a dynamic equilibrium position under the action of the centrifugal force. A segment having a length of about 400 mm comes into a rest position against the bottom of the spout upon the action of the centrifugal force. Its length is sufficient to allow easy checks of full bobbins.
(FR)Le dispositif d"accrochage comporte un equipage mobile (15, 16) qui est accouple au disque (2) entrainant la bobine (1) et peut se deplacer axialement. Cet equipage est commande par le verin (9, 10). Il comporte une goulotte (18) qui commande le crochet (20) auquel le brin d"entree s"accroche lors du transfert du fil au debut du bobinage sur la bobine vide. Apres quelques tours de bobinage, effectues par la bobine (1), le crochet (20) est ouvert par deplacement de l"equipage mobile dans le sens axial dans la position representee en traits mixtes. Le brin initial du fil se degage du crochet et prend une position d"equilibre dynamique sous l"effet de la force centrifuge. Un segment ayant une longueur de l"ordre de 400 mm vient s"appuyer contre le fond de la goulotte par l"effet de la force centrifuge. Sa longueur est suffisante pour que les controles sur bobines pleines puissent s"effectuer facilement.
