<p><P>PROBLEM TO BE SOLVED: To provide a multi-layer coil of multiple wires for a transformer and its winding apparatus, for achieving a coil for a transformer and a winding method capable of increasing the capacity of the coil at lower costs. <P>SOLUTION: A plurality of individually fed flat-type electric wires 1A, 1B are held in an overlapped constraint state by a bonding agent coated by a bonding agent coating mechanism 2, molded by a molding unit 10 like a single flat-type electric wire 1, and stacked in a disk shape in a stacking unit 11 to provide the multi-layer coil using the plurality of flat-type electric wires. The multi-layer coil can attain the effect equivalent to an increase in the cross-sectional area of the single flat-type electric wire and a molded transformer of a large capacity can be realized. Further, by additionally providing a mechanism for keeping the flat-type electric wires 1A, 1B in an overlapped state in a winding machine, the multi-layer coil using the plurality of electric wires can be manufactured at lower costs. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
