    Differential shaft is mainly used for machine parts that has high requirement on final products and fast speed, especially for high speed slitting machine. The differential ring on it can slip independently. The amount of slip exactly compensate for the difference in speed, thus it can control the tension of each roll precisely, which ensure the winding quality, overcome the problem of unwinding and material damage.



  1. The differential ring on differntial shaft can slip independently, it is the main part for differential shaft which is with tension adjustment.
  2. Controlled by the tension system, make the compressed air which has a certain pressure come to shaft core, so that it will produce friction torque between the friction parts and the slip ring.
  3. For high speed machine, the precision is very important, differential ring combined differential shaft is more economy for customer's machine.

  • Difference in material thickness often arises when unwinding plastic films or other material. In the process of constant winding, this difference can lead to obvious discrepancy in outside diameter of roll, and slight discrepancy in winding torque under this situation.
  • After some winding rotation, some rolls may start to loosen, leasing to quality decline in product eventually.
  • It works under the theory that friction rings slip constantly to keep same tension, some rings slip faster than others. So tension of each roll can be controlled accurately, and permanent tension can also be gained to guarantee the quality of roll.
  1. For some high speed machine, especially high speed slitting machine, the use of differential shaft ring improves the stablity of the slitting machine .
  2. The use of differential shaft ring improves the stablity of the slitting machine,espceially for high speed machine.
  3. The differential shaft combined by differntial shaft can make the accuracy of the winding and the degree of automation.At the same time,it shortens the preparation time and achieve the humanized operation. 
  4. Differential shaft ring to wind or unwind precious materials, metal foil and special paper roll, can greatly reduce the cost of production.
  5. For customer, speed and pricision is money, differntial ring and differntial shaft can make high speed machine stable and precisely, Higher efficiency and higher economic benefits

A.The applicable Machine

It is used for slitting machine,coating machine,cutting machine,printing machine,compounding machine,paper making machine,bag makeing machine, embossing machine and so on .It can greatly improve the working efficiency and the quality of products.

B.The applicable Material
