ABSTRACT:
The operation of a flier-type armature winding machine is monitored to detect if a tang connection is missed and for interrupting the operation of the machine in such event. Differences in wire usage between those cases in which a tang connection is successfully made and those cases in which a tang connection is missed are detected and, if the differences are substantial, the operation of the armature winding machine is terminated. The monitoring is done with a shaft encoder and an add-subtract counter by which is computed the degrees of forward and reverse rotation of a guide pulley over or around which the wire is coursed. In a modification, up and down movements of a dancer pulley are monitored to provide an indication of wire usage.
