Title:
METHOD FOR MANUFACTURING TAPPED COIL, TAPPED COIL, AND APPARATUS FOR MANUFACTURING TAPPED COIL
Document Type and Number:
WIPO Patent Application WO/2002/021544
Kind Code:
A1
Abstract:
A method for manufacturing a tapped coil having a strong tap made upper of loops wound with a high efficiency, a tapped coil, and an apparatus for manufacturing a tapped coil are disclosed. A tap composed of a single loop or loops can be formed easily even at the start of the winding or at the end of the winding in the axial direction of the tapped coil. A coil wire (4) supplied from a coil wire supply unit not shown in the drawing is wound around a winding core (1) by rotating the winding core (1) while moving it in the direction indicated by an arrow (15) with respect to the fixed coil wire supply unit. A protruding bar (5) is protruded generally parallel to the winding core (1) when it is necessary and rotated around the winding core (1) in the direction indicated by an arrow (11) in synchronism with the rotation of the winding core (1); and the coil wire (4) is hooked on the protruding bar (5) and wound around the wiring core (1) and the protruding bar (5); thus forming loops (6a 6b). After the winding step, a tap (7) is formed by stranding the loops (6a, 6b) at another step to manufacture a tapped coil (6).
