They are mainly used to roll up all kinds of cales with big diameter. THE UNIQUE FEATURE:1.  The first structural style of the upright column:the square structure.2.  The second structural style of the upright column:the double-column structure3.  The wheel gear with the hard suface is used in the take-up garbox,so the driving torque is high and the noise is low.4.  The direct current contr ol is used for take-up and tranver sing,the direct current control of Oulu590+used as take-up,and the frequent current control used as tranversing,The ten sion should be controlled constantly when taking up,and the take-up speed sh ould be followed automaticly by tranversing,The tranversing lay and the take-up tension can be setted in the touched screen(Siemens)
