Abstract
A device for the manufacture of coils in which the winding wire is guided to a winding head via a winding drum having an eccentric wire guiding bore. The winding drum and the winding head rotate in opposite directions so as to achieve an effective winding speed greater than either rotational speed.
Claims6
An apparatus for winding coils in which wire is guided by a winding drum having an eccentric axially extending bore movable in the direction of winding about a retractable mandril to a winding head, comprising
- a winding head having an axis,
- a slide mounted for relative movement with respect to said winding head in a direction parallel to said axis,
- a winding drum mounted on said slide coaxially with said winding head for rotation about said axis, said drum having an eccentric axially extending bore,
- means for supplying wire to be wound to and through said bore, at least a part of said supplying means being adjacent said drum
- means on said winding head for clamping a wire end thereto,
- a mandril mounted coaxially in said winding head,
- means connected to said mandril for moving said mandril axially with respect to said winding head, and
- means connected to said winding head and said drum for rotating said winding head and said drum about said axis in opposite directions, said winding head being rotated at a speed between approximately 50% and 150% of the speed of the drum.
