The automatic line is used for cold rolling of wires at a speed of up to 4 m / s and their subsequent processing by cutting into brushes. The line consists of several stations. There is a gradual hydraulic bending of the sheet metal envelope and then assembly with a bundle of wire and brush shape calibration. The line is equipped with an air-conditioned overpressure switchboard and other elements that enable long-term operation in an environment with airborne steel dust. There is also included a robotic workstation with a Yaskawa GP50 robot with a gripper for gripping and trimming wire ends.
