Device for forming taps when winding electrical coils

摘要

A hook for engaging a wire, holding it outside of the winding zone and releasing the same prior to completing the winding of the next coil, is movably mounted on a drive shaft, is connected thereto through a spring and has a stop near the shaft. The shaft is mounted in a housing movable with respect to the wire guide of the machine for winding the coils and is provided with a projection rigidly secured thereon for interaction with the stop of the hook. The mobility of the housing can be provided by mounting it in hinges on the machine bed or on a telescopic shaft, in which case the housing is controlled by a cam mechanism under action of which it moves the hook to the winding zone and removes it therefrom. During the operation the hook permanently rotates on the shaft at a predetermined speed and is periodically introduced into the winding zone for forming the taps.
