Methods, apparatus, systems, and computer-readable media are provided for tracking amounts of wires provided to a winding head during a winding operation of a wire distribution system. The wires can be tracked using one or more wire tracking devices that can be disposed at one or more locations within the wire distribution system. The wire tracking devices can provide information related to the amounts of wires and the types of wires being used to wind about a winding head/form. The information can be used to check for errors during a winding operation and indicate the progress of the winding operation. The information can also be used to update wire-availability data to reflect the amount of wire that has been provided during the winding operation.

A coil forming apparatus includes: a coil winding jig being configured to wind the belt-shaped coil by inserting the plurality of straight portions of the belt-shaped coil into a respective one of the plurality of comb-shaped grooves; a coil conveying mechanism that pivotally conveys the belt-shaped coil; and guide members that guide the belt-shaped coil in an arc shape while being in contact with the side ends of the belt-shaped coil, and further allow the plurality of straight portions to be inserted into a respective one of the plurality of comb-shaped grooves in a second half portion of the belt-shaped coil upon pivot conveying. The coil conveying organizer includes a conveying rail that provides a conveying path pivotally conveying the belt-shaped coil along the coil winding jig, and a conveyor that moves along the conveying rail in a state gripping the plurality of straight portions of the belt-shaped coil.
