Title (EN) THREAD BRAKING DEVICE FOR A WEFT FEEDER DEVICE
(FR) DISPOSITIF DE FREINAGE DE FIL POUR UN DISPOSITIF D'ALIMENTATION DE TRAME
Abstract:
(EN) Thread braking device for a weft feeder device (1) comprising a annular braking band (15) for forming a braking zone (16) for a weft thread (7), wherein the braking band (15) is supported by the support structure (17), wherein the support structure (17) is at least partly elastically deformable by an axial force exerted on the support structure (17), wherein the support structure (17) is provided with at least one stiffening element (41, 43) surrounding the braking band (15) at a rear side of the braking band (15), wherein in a non-deformed state of the support structure (17) the braking band (15) is arranged at a distance of the stiffening element (41, 43) and by exerting an axial force on the support structure (17), the support structure (17) is deformable so that the braking band (15) at the rear side of the braking band (15) is supported by the stiffening element (41, 43). Weft feeder device with such a thread braking device (3).
(FR) La présente invention concerne un dispositif de freinage de fil pour un dispositif d'alimentation de trame (1) comprenant une bande de freinage annulaire (15) destinée à former une zone de freinage (16) pour un fil de trame (7), la bande de freinage (15) étant supportée par la structure de support (17), la structure de support (17) étant au moins partiellement déformable élastiquement par une force axiale exercée sur la structure de support (17), la structure de support (17) étant pourvue d'au moins un élément de raidissement (41, 43) entourant la bande de freinage (15) au niveau d'un côté arrière de la bande de freinage (15). Dans un état non déformé de la structure de support (17), la bande de freinage (15) est disposée à une certaine distance de l'élément de raidissement (41, 43) et en exerçant une force axiale sur la structure de support (17), la structure de support (17) est déformable de telle sorte que la bande de freinage (15) au niveau du côté arrière de la bande de freinage (15) est supportée par l'élément de raidissement (41, 43). Dispositif d'alimentation de trame comportant un tel dispositif de freinage de fil (3).
