A coil stripping apparatus that strips a coil of thin flexible material from a drum of coiling machine comprises a non-rotating pusher plate slidably movable along the length of the drum, as powered by a hydraulically actuated motor for effecting the transport of the coil along the drum. A stripper member having opposed first and second finger members, with the first and second finger members each having a base portion and a projecting portion, is rotatably mounted with respect to the non-rotating pusher plate for co-rotation with the drum about the longitudinal axis. The stripper member is in contact with one or the other of the first and second drive surfaces so as to be slidably movable along the length of the drum by the non-rotating pusher plate. The projecting portions are shaped and dimensioned to enter respective co-operating substantially longitudinally disposed first and second generally opposed slots in the drum, thereby to permit the stripper member to engage the entire radius of the coil at two generally opposed orientations and so as to permit the coil to be subsequently moved longitudinally along the drum and removed from the drum.
Cette invention concerne un éjecteur de bobines de matériau mince flexible associé au tambour d'une machine à bobiner. Il comprend une plaque de poussée non rotative destinée à coulisser le long du tambour sous la commande d'un vérin hydraulique pour repousser le matériau bobiné du tambour. Un anneau éjecteur comportant deux ergots intérieurs opposés est monté sur le tambour de manière à tourner avec lui par rapport à la plaque de poussée. Cet anneau est en contact avec l'une ou l'autre de deux faces d'une gorge annulaire ménagée dans le pourtour intérieur de la plaque de poussée, cette disposition assurant sa translation dans un sens ou l'autre le long du tambour. Les ergots susmentionnés ont une forme et des dimensions conjuguées à celles de deux rainures longitudinales opposées du tambour pour pouvoir s'insérer dans celles-ci et permettre à l'anneau de prendre appui en deux points généralement opposés contre toutes les spires de la bobine, évitant ainsi sa déformation en cours de translation le long du tambour vers l'extrémité libre de celui-ci.
