Quick details
Air differential shaft is applied mainly to wind shaft, or unwind
shaft in special occasions.The body of the air differential shaft
is made from chrome-plate steel. The friction plate can be made
from polyurethane, polyethylene, or rubber to max tension required.
The differential shaft is composed of a plurality of differential
rings, and the friction torque of the differential ring is
controlled by the air pressure, so that the tension of the inner
roll to the outer roll will be constant. The shaft can make a neat
ends, and the material tension is constant.
The use of the differential shaft, can make the speed of the
slitting machine, the accuracy of winding, the grade of automation,
the reduction of preparation time, the humanization of operation
improved. Differential shafts have been widely used in plastic film
(including electronics, capacitors, battery film, plastic wrap,
packaging, composite film); metal foil (copper foil, aluminum foil,
etc.); paper roll; PVC sheet material and so on . It is currently
being extended to other fields and industries, and other special
materials for winding and rewinding.

Feature of Air Differential Rewinding Core Shafts
- 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 become very tight, and
meanwhile, some other rolls may start to loosen, leasing to quality
decline in product eventually.
- Our differential air shaft with slipping friction can ensure the
highest winding quality, and by keeping proper tension on all rolls
throughout the winding operation, materials will not show any
problem.
- It works under the theory that friction rings slip constantly in
center of air shaft, and 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.
- According to different roll diameters, to control air pressure of
rubber tube and to stable the tension, a constant air pressure
source kept by rotary joint is required.
Component
Central air pressure differential shaft are made of core roll,
differential ring, rubber tube, friction parts, sealing rings.
The body shaft of the air differential shaft is made from
chrome-plate steel. The friction plate can be made from
polyurethane, polyethylene, or rubber to max tension required.
Differential ring is made in aluminum with hard anodize or steel
material with chrome coating.

Application
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.
