Apparatus and method for use in developing wound coils

Abstract

Monitor position of winding flyer in relation to a machine frame, substantially continuously generate signals indicative of flyer position, and control relative jump of coil forms and flyer in response to signals. Jump is initiated during predetermined portion of a flyer revolution while flyer is in 'jump window' relative to turn receiver. Energy stored in lost motion mechanism contributes to acceleration of jump mechanism; and same mechanism absorbs and stores energy as moving structure stops. Parts of coil forms are adjusted substantially equal distances relative to a geometric center and turn receiver and winding head undergo relative movement to maintain mutually aligned relationships. Fast and consistently responsive latch mechanisms insure jump during fraction of flyer revolution in different machine cycles. Jump mechanism urged against latches by pre-loaded spring mechanism for increased acceleration and to absorb prime mover force at end of jump stroke. Fast response diaphragm piston operated latch mechanisms perit initiation of jump stroke. Means adjust coil form parts in opposite directions while form parts remain centered relative to flyer axis. Device maintains desired alignment of at least one coil form part and winding turn receiver. Screw with spaced apart right-hand and left-hand threads move coil form parts relative to one another.
