Device for the automatic change-over of the form in a coil winder for forming the winding of a dynamo-electric machine

摘要

In a coil winder for forming the winding of a dynamo-electric machine, the change-over of the form on which coils of the winding are wound is effected automatically. A rotatable platform is located beneath the form and is movable in the direction of its axis of rotation between a position close to the form and a position spaced herefrom. The platform has an empty bearing zone for the form intended to be removed from the coil winder and a support zone occupied by the replacement form. When it is wished to replace the form, the rotatable platform is arranged in its close position with the empty zone beneath the form to be removed and the latter is deposited on it by the deactivation of the rapid-attachment connection which connect the form to the coil winder.
