7、 Herringbone board is a special oxide material made of aluminum guide roller rolling, which reduces the friction coefficient of the thin film, prevents static electricity, and improves the cooling and emission speed. Due to the high temperature of the surface forming of the printing film after surface corona treatment and printing on the printing machine, it will produce scratches when blowing the film with a conventional herringbone board. If light colored ink is printed after printing, it is easy to leak scratches and wire drawing phenomena,

8、 Edge correction machine. Equipped with ultrasonic sensor probe, servo brushless motor, LED LCD display screen, high-precision correction of running errors, eliminating old-fashioned DC motors.
