REEL STAND |
|
| 4. |
Reel Stand With Pneumatic Disk Break |
The reel stand RSDB is provided with pneumatically operated disc brakes in lieu of spring controlled shoe brake.
In this model the position of the dancing arm is controlled by a special valve, which is separated by a cam.
The dancing arm through the disc brake controls the Web Tension. Due to inherent design of the disc brake system and pneumatic control this system controls the tension better than shoe type brake with spring control. |
| 5. |
Reel Stand With Pneumatic Reel Changer |
| The arrangement loads and unloads the reels from the stand through the pneumatic cylinders. The required control circuit for the pneumatics is provided. The lifting and lowering is done by a manually controlled direction value. |
