Dry drawing, straightening and cutting line
Standard die or roll type drawing lines come supplied with a rod straightening and cutting unit. Wire rods are then coated to form electrodes. Combining the drawing and cutting processes is extremely advantageous because production is non-stop, and, by using a two-position pay-off and in-line rod preparation unit, it is possible to reach notable levels of effi ciency. Maximum cutting speed is 8 m/s.
