application: fruit paper bag,cement bag, kraft packing bag, envelope kraft paper
1.The rewinder is designed to rewind the paper from the paper machine into rolls with desired width and tightness as final products.
2.The machine is available in types of 3 point driving and single point driving.3 point driving .two DC motors are used to drive the front lower roller and the rear lower roller,respectively ,so as to move paper at a low speed in positive direction.
3.The speed difference between the two lower rollers vary automatically with the changes in the diameter of paper roll.
4.The starting speed slope can be preset. Stop can be realized by electric control and brake device .
5.Paper back moving acting is driven by a separate DC motor.
6.Therefore, paper can be moved in both direction at low speed and the stand still tension can be established.
7.The constant tension is automatically provided when rewinding.
8.Stop can be realized by electric control and brake device.
9.Through the process of 3 point rewinder,the paper can be get improvements in tightness and quality.
