Slip shaft is also called differential slip shaft,sliding shaft,etc,it is the main working parts on slitting & rewinder machine, used for a variety of packaging material cutting. In the process of winding in the event of material of uneven thickness and machine tension control is not stable, volume will be affected by devolume phenomenon and the whole volume of material elastic inconsistent caused material damage,slip shaft as the main body, the center of pressure control, the slip sleevethree piston out, and then promote each torque set piece outward expansion, and according to the size of the set pressure of each torsion.

1, wide range of speed regulation, with constant torque load in such as printing machine, generally up to 10:1, there are special requirements (such as the web) is up to 50:1;

2, adjustable torque. In the modern United Press, use paper tension machinery automation, it canachieve the changes with the reel diameter, torque regulation clutch by keep tension constant;

3, stepless speed regulation, high hardness and mechanical properties;

4, has the advantages of simple structure, reliable work, convenient maintenance, low price.
