Chuck head with rotatable feeding movement

A chuck for winding a conductor wire into a toroid comprising a frame having a base wall and a spaced front plate parallel therewith, a front shaft and a rear shaft rotatably journalled within said base wall and front plate, a rotatable core on which said wire is wound into a toroid, said core being located between said front and rear shafts, a first and second toroid clamping rollers mounted respectively on each of said front and rear shafts, said first and second toroid clamping rollers being adapted to engage therebetween the wire toroidally wound on said core, a supporting shaft rotatably journalled between the base wall and the front plate spaced from and parallel with the front and rear shaft, a bracket pivotally supported by said supporting shaft, a lateral shaft journalled on said bracket, a third clamping roller mounted on said lateral shaft, said lateral shaft being positioned on said bracket to move toward and away from said frame on pivoting said bracket, so that said third supporting roller is adapted to selectively engage the surface of said wire wound on said core, and spring means for normally biasing said bracket toward said frame, transmission means for simultaneously rotating the front, rear and lateral shafts at a uniform speed and in the direction of rotation of said core, so that said clamping rollers cooperate to rotate the wire wound on said core, and motor means for driving said gear means.
