Abstract

Apparatus for manufacturing multiple transformers simultaneously by winding several wire coils on bobbins and applying tape over each coil includes carriage mechanisms which are independently movable along three mutually perpendicular axes and orbitally about one of the axes. Separate drive mechanisms for each mode of movement include drive motors mounted on a stationary frame, thereby reducing the mass of the moving elements of the apparatus and permitting rapid changes in speed and direction of movements. Carriage-frame structural interlocks also provide low mass with rigidity to the carriage elements. A simple winding pitch adjusting mechanism, incorporating a drive lever with a variable pivot point, also forms part of the apparatus and also has a separate frame-mounted drive motor, as does a taping mechanism for applying tape over each wound coil. A group of bobbinrotating spindles are connected to be driven by one of the framemounted carriage drive motors. The various mechanism of the apparatus are automatically operated in proper timed sequence according to programs provided for by a program-controllable card reader device and an automatic control system including a sequencing device in the form of a rotary, switch-actuating drum.
