PROBLEM TO BE SOLVED: To provide a wire net corrugated wire capable of suppressing the out-of-plane deformation of the wire net, and corrugated wire manufacturing device and method.SOLUTION: A pair of upper and lower rolls 11 has a plurality of recessed holes 13 arrayed in the circumferential direction of an outer peripheral plane and slender in the circumferential direction, a vertical sectional shape at its width-direction center position has a recessed bent shape gradually shallower from a depth substantially equal to a wire material diameter at the circumferential middle part of the recessed hole toward both ends in the circumferential direction, a boundary part between the recessed hole and a roll outer peripheral part 11a has a projected bent shape projected outward in a radial direction to be smoothly continuous to the roll outer peripheral surface, and a roll outer peripheral surface part between the adjacent recessed holes constitutes a projected part 15 in which roll bent shape parts 14 are both shoulder parts. The cross sectional shape of the recessed hole is deepest at the width-direction center position and shallower toward width-direction both ends. A roll rotation driving mechanism 16 rotary-drives both rolls in a state where roll outer peripheral surfaces contact with or approach each other at a small gap and a state where the recessed hole of one of the rolls faces the projected part of the other roll.SELECTED DRAWING: Figure 6 |
