Abstract
A multiply connected air core coil winding apparatus is provided in which a winding core is protruded and retracted through a first side frame in order to position the winding core between the first side frame and a second side frame, the winding core being rotated when so positioned in order to form a side face of an air core coil. The second side frame is capable of being drawn towards and away from the first side frame. A pocket is provided at one of the side frames for housing the air core coil when the winding material has been completely wound. As a result, multiple air core coils can be wound without cutting the winding material of a first air core coil. In a second embodiment of the present invention, a multiply connected air core coil winding apparatus is provided, comprising a winding core which can be protruded and retracted through a hole of a side frame face so as to be positioned between a pair of side frames, the winding core being rotated for forming a side face of an air core coil, similar to the first embodiment. One side frame is movable so as to be drawn towards and away from the other side frame, and a plurality of side frame faces are provided on one of the side frames which can be rotated in a direction perpendicular to a winding rotation shaft. One side frame is positioned so as to be opposed to the other side frame, and the winding core is protruded and retracted on the rotation shaft of the winding wire.
