一. Product introduction

  SET-2000-R for the cylinder with the attenuation function of the servo tension device, suitable for large tension when the wire diameter winding. It consists of the traditional passive wire instead of active motor wire, by changing the spring tension change value; and use of the control pressure, the system can automatically switch back tension during the winding process of big and small two to avoid breakage. The tension is not affected by the line speed, cover, and felt the tension pulley, particularly stable, simple and convenient adjustment.
