<p>PROBLEM TO BE SOLVED: To reduce sticking amount of dross generating when a material is cut by laser beam or the like. SOLUTION: A triangular-wave formed product made by bending a steel strip is plurally placed side by side and joined to form planar blocks 3, with each block 3 inclined and plurally arranged on a plane; the corner part 5 situated uppermost by the inclination of each block 3 is positioned on a placing plane W1 on which a material W to be cut is placed; air flow forming spaces, which are formed in each block 3, are nearly perpendicularly communicated; and the material W is designed to be supported in point contact or linear contact with the corner part 5.</p> |
