The main motor is controlled by a frequency converter,stable and reliable digital pulse closed loop relying PLC instruction to ensure a constant speed of fast,slow,reverse and winding retreat.

The bracket movement of the beam is controlled by pneumatic,mechanical positioning,accurate and reliable which guarantees the warp beam stable when loading and unloading.The position of beam is accuracy controlled by photoelectric and the PLC automatically,which select the different position according to beam's diameter.

The tail stock is equiped with center fixing shaft head which is controlled by pheneumatic.The advantage electric scaling valve brings out the locking pressure suitable for different warping beams accodiny to the PLC order.So the damage which is caused by shaft head will be dropped to the minimum.
