The special copy function guarantees the data of every beam are the same in the same group, like the circle number, meters and diameter. This function avoids that the yarn quantity is not unique caused by different diameters, which can reduce the waste of yarn.

◆The main motor is controlled by converter. The constant and reliable digital pulse close ring controlled by the PLC guarantees the speed of winding and storing yarn is stable.
◆The bracket movement of beam is controlled by pneumatic, and its position is accuracy controlled by photoelectric sensor and the PLC automatically, which select the different position according to beam's diameter.

◆The tail bracket is controlled by pneumatic, and the shaft adepts centre fixing shaft head. These two features make the damage to inner beam caused by the shift lower down to the minimum.

◆The main brake adepts pneumatic butterfly brake. The breaking tray with middle unoccupied has a nice heat-dissipated function. On the other hand, the using of break pincer with auto-compensation and the hoofed piece makes the butterfly brake stable and last a long life.
