Single head 3/4 system double roller model. Full-motor super-small head, rapid rotation, motor turning needle, turning needle head without waiting, two-way shaking table function, effectively reduce head stroke and row number, greatly improve machine stability and efficiency. The main and auxiliary rollers cooperate with each other to perfectly combine the pulling and dynamic functions, which can effectively improve the problem of different length of the collar and increase the flatness of the collar. The new two-stage gauge realizes the separate control of the main and auxiliary gauges without increasing the number of motors.
