This traverse shaft 6 has a pulley 7,
It is interlocked and connected to an output shaft 11 of a pulse motor 10 via a timing belt 8 and a pulley 9.
Further, the traverse shaft 6 is configured to be able to change the angle θ with respect to the former shaft 2. The pulse motor 10 rotates at a number of rotations proportional to the number of drive pulses output from the drive device 12.

The comparison device 13 stores a signal from a rotation detection device 14 provided on the former shaft 2, a signal from a rotation detection device 15 provided on the output shaft 11 of the pulse motor 10, and a predetermined winding pattern. Storage device 16
The former shaft 2 outputs a predetermined signal corresponding to the memorized winding pattern to the drive device 12 every time the former shaft 2 rotates once, and rotates the output shaft 11 of the pulse motor 10 at a predetermined rotation speed. The feeding head 5a, 5b is rotated by a predetermined amount to step feed the feed heads 5a, 5b by a predetermined amount.

Specifically, as shown in FIG. 4, the former rotates at the same time as the machine starts operating, and when the rotation detection device 14 detects this, the matching circuit A is activated and the counter C detects the amount of feed pulse per revolution. Pulses are repeatedly sent to the pulse motor 10 via the drive device until the setting S is reached, and the wire is moved by one pitch. By continuously rotating the former, the first stage winding is repeated every time the rotation detection device is activated, and then the first stage winding is performed until the counter F reaches the first stage winding number E1. When the counter F reaches the first stage winding number E1, the stage switching circuit G is switched from the matching circuit D.
automatically switches to the second stage winding number setting and enters the second stage winding. Thereafter, the winding operation is repeated in sequence, and the winding operation is completed when the final stage is completed.

In the above configuration, when winding the wire 4 around the formers 3a and 3b to form a tire bead, the program loader 18
A program for obtaining a desired winding pattern is stored in the machine. Next, a winding pattern program as shown in FIG. 2, for example, is inputted from the storage device 16 to the comparator 13 to start the winding operation. The tip of the wire 4 is held by the formers 3a, 3b, and the wire 4 is wound up as the formers 3a, 3b rotate. And former 3a,
Each revolution of the supply heads 5a and 5b is moved by the pulse motor 10 by the amount of movement set in the program, and by repeating this operation, each former is moved to match the winding pattern set at the beginning. A wire 4 is wound around the formers 3a and 3b, and a tire bead of a desired winding pattern is formed on each former 3.
