The active pay-off stand is suitable for the workplace where precise control of pay-off is required and the weight of the spool is heavy. It can automatically track the speed of the pay-off and pay-off and provide constant tension as required by the process. For example, it is used for pay-off of high-speed stranded wire (multi-head wire drawing reel pay-off), pay-off of high-speed wire extrusion production line (small square wire and the total weight of pay-off reel is too large), pay-off of twisted machine, etc.
