Coil manufacturing apparatus, and coil manufacturing method

A coil manufacturing apparatus configured to form a helical structure body by joining a plurality of flat conductors, the apparatus comprising:

• a welding device configured to form a welded product of the plurality of flat conductors;
• and
• a removing device configured to remove a portion of the welded product, wherein
• the welding device is a unit configured to press end faces of one flat conductor and another flat conductor among the plurality of flat conductors against each other along a strip longitudinal direction and to join the one flat conductor and the another flat conductor to form the welded product that is to be the helical structure body,
• the welded product that is taken out from the welding device is configured such that all one turn regions of the helical structure body are in a wider state than the helical structure body in a completed state,
• the removing device is a unit configured to have a coil piece holding portion and a cutting unit and to remove a burr generated by pressing of the plurality of flat conductors,
• the coil piece holding portion holds the welded product after being taken out from the welding device so as to maintain a shape of the welded product at least in a vicinity of a region where the burr is formed, and
• the cutting unit relatively moves with respect to the coil piece holding portion to remove the burr.
