ABSTRACT OF THE DISCLOSURE A fast set up tooling arrangement for a coil placing machine is disclosed wherein the finger elements or blades which support coils as well as a magnetic core into which the coils are to be placed, as well as the reciprocable ram actuated stripper which is movable along those finger elements to engage and move coils into the magnetic core are readily adjustable axially of the ma- chine to accommodate changes in the height of the magnetic core or stack. The arms which grip the core and the length of insulating wedges to be placed in the core may also be adjustable. The axial extent of the finger elements or tooling blades as well as the axial distance traveled by the stripper are simultaneously adjusted by imparting a relative rotary motion between the stripper and finger elements on the one hand and a finger support shaft and stripper actuating ram on the other hand with the respective ro- tated and fixed elements being threadingly interconnected. To effect stack height adjustment the stripper and its ac- tuating ram are moved to their extended position at which a key interlocks the stripper actuating ram and a threaded finger sup- port shaft to prevent relative rotation therebetween. The strip- per and finger elements are also interlocked in this position and in one embodiment a driven gear arrangement engages and rotates the actuating ram and threaded finger support shaft to move threadingly mated second stripper engaging ram portion and a threaded finger holder having the finger elements disposed about its periphery. In another embodiment when the stripper is exten- ded and the ram and threaded tooling shaft are rotationally inter- locked, neither is allowed to rotate, and a somewhat conventional tool indexing arrangement rotates the stripper and finger elements, causing their respective axial movement.
