<p>PROBLEM TO BE SOLVED: To realize a weaving processing by obtaining rotation laser beams with the diameter corresponding to width of a gap between works. SOLUTION: A housing 4 is rotatably arranged directly under an optical fiber ejection part 9A, and a mounting angleθof a glass plate 3 installed in the housing 4 is set corresponding to a width D of a gap G between works W1 and W2, so that a laser beam L ejected from the optical fiber ejection part 9A is bent and decentered by the glass plate 3 in the rotating housing 4. Then, weaving processing is applied to the works W1 and W2 while a rotation laser beam RL with a diameter d corresponding to the width D of the gap G between the works W1 and W2 is radiated.</p> |
