Then, the output side clamp 51, the output side upper electrode 52a, and the input side upper electrode 62a are respectively raised by the clamp pressurizer 54 and the electrode pressurizers 55, 65, and the trailing coil 2 welded to the preceding coil 1 is inserted into the input side clamp 61. Just fix and move stand 60 upset cylinder 68
Is moved by a distance X so that the welding line of the leading coil 1 and the trailing coil 2 coincides with the center line of the trimmer tool 30. The above corresponds to the position control means. Then the preceding coil 1,
The trailing coil 2 is set at the trimming position shown in FIG. 3 regardless of the material, plate thickness, and plate width.
Adjusting amount 41-16 = 25 from the reference position and input side electrode 62
Adjustment amount from the reference position of 41- [32- (U + V + 1
-Y) + X] is calculated and based on this, the stock removal amount adjuster 5
With 3, 63, the output margins of the output side electrode 52 and the input side electrode 62 are adjusted.
The above corresponds to the margin adjustment means. It should be noted that U + V + 1-Y and X, which are adjustment amounts of the insertion amount from the reference position of the entrance-side electrode 62, are distances moved by the moving table 60 by the upset cylinder 68. After that, the leading coil 1 welded to the trailing coil 2 is fixed by the outlet side clamp 51, and the outlet side upper electrode 52a and the inlet side upper electrode 52a are fixed.
62a is also tightened and fixed, and the tool holder 31 holding the trimmer tool 30 is advanced along the guide of the fixing base 50,
The flash and the flash of the welded portion of the leading coil 1 and the trailing coil 2 are cut. The welding line of the leading coil 1 and the following coil 2 coincides with the center line of the trimmer bite 30, and the positions of the output side electrode 52 and the input side electrode are close to each other and equidistant from the welding line.
Since it is fixed by 62, there is no uncut portion, and even if the leading coil 1 and the following coil 2 are thin, the rigidity balance is not lost and the cutting is not adversely affected.

失なわず、安定した切削性の得られる効果がある。As described above, according to the present invention, the position control means is provided to calculate the distance between the welding line of the preceding coil and the following coil and the center line of the trimmer bit after the completion of the flash welding, and the calculated distance is calculated. Based on this, the moving table is moved with the leading coil and the trailing coil fixed by the inlet side clamps, and in addition to aligning the welding line with the center line, a feeding allowance adjusting means is provided and the welding line is sandwiched between The output allowance adjustment amount for each of the output side electrode and the input side electrode is calculated in order to fix the predetermined positions of the preceding coil and the following coil that are equidistant by the output side electrode and the input side electrode, and based on this, the respective output allowances are calculated. Since the adjustment is made, there will be no unburned part even if the flash and the flash of the welded part of the preceding coil and the following coil are cut, and it is rigid even if the plate thickness of the preceding coil and the following coil is thin. Stable without losing balance There is an effect capable of obtaining machinability.
