Abstract
(EN) The swivel knife holder assembly includes a shoulder screw defining an axis, and having a proximal threaded end and a distal head, and mounted on the shoulder screw is a bobbin assembly. The swivel knife holder assembly also includes a shell defining an interior, and having a distal opening and a proximal opening. A core is secured in the interior and is coupled to a knife for cutting fabric material. The proximal opening of the shell is defined by a flange and houses the shoulder screw therein. Threadably coupled to the proximal threaded end of the shoulder screw is a stem. The stem secures the bobbin assembly within the shell and also includes a mounting surface for engaging a reciprocating drive mechanism.
(FR) La présente invention concerne un ensemble porte-couteau pivotant qui comprend une vis d'épaulement définissant un axe et ayant une extrémité filetée proximale et une tête distale et un ensemble bobine est monté sur la vis d'épaulement. L'ensemble porte-couteau pivotant comprend également une coque définissant un intérieur et ayant une ouverture distale et une ouverture proximale. Un noyau est fixé à l'intérieur et est couplé à un couteau pour couper un matériau de tissu. L'ouverture proximale de la coque est définie par une bride et loge la vis d'épaulement à l'intérieur de celle-ci. Une tige est couplée par filetage à l'extrémité filetée proximale de la vis d'épaulement. La tige fixe l'ensemble bobine à l'intérieur de la coque et comprend également une surface de montage pour venir en prise avec un mécanisme d'entraînement en va-et-vient.
