Abstract

The present invention provides a conveyor belt tracking system for a dryer having a web of a mesh material having a protrusion extending along the length proximal one lateral edge and above a flat surface and a first generally cylindrical roller having a three-tiered slot for receiving the protrusion and two flanking shallow tracks for receiving base flanges.

Claims (38)

1. A method for operating a textile dryer having multiple belts and multiple drying zones comprising:

entering an initial belt speed for a first conveyor of the dryer in a first zone of the dryer;

entering an initial belt speed for a second conveyor of the dryer in a second zone of the dryer;

entering an initial first ambient condition for the first zone of the dryer;

entering an initial first ambient condition for the second zone of the dryer;

operating the first conveyor to run in the first zone; and,

operating the second conveyor to run in the second zone.

2. The method of claim 1 further comprising:

measuring the belt speed of the first conveyor during operation.

3. The method of claim 2 further comprising:

measuring the belt speed of the second conveyor during operation.

4. The method of claim 3 further comprising:

increasing the speed of the first conveyor if the measured belt speed of the first conveyor is less than the initial belt speed of the first conveyor.

5. The method of claim 4 further comprising:

increasing the speed of the second conveyor if the measured belt speed of the second conveyor is less than the initial belt speed of the second conveyor.

6. The method of claim 3 further comprising:

decreasing the speed of the first conveyor if the measured belt speed of the first conveyor is greater than the initial belt speed of the first conveyor.

7. The method of claim 6 further comprising:

decreasing the speed of the second conveyor if the measured belt speed of the second conveyor is greater than the initial belt speed of the second conveyor.

8. The method of claim 3 further comprising:

providing heated air under pressure to the first zone of the dryer if the measured belt speed of the first conveyor is equal to the initial belt speed of the first conveyor.

9. The method of claim 8 further comprising:

providing heated air under pressure to the second zone of the dryer if the measured belt speed of the second conveyor is equal to the initial belt speed of the second conveyor.

10. The method of claim 9 further comprising:

measuring the first ambient condition in the first zone during operation.

11. The method of claim 10 further comprising:

measuring the first ambient condition in the second zone during operation.

12. The method of claim 11 further comprising:

adjusting the first ambient condition in the first zone if the measured first ambient condition in the first zone is not equal to the initial first ambient condition in the first zone.

13. The method of claim 12 further comprising:

adjusting the first ambient condition in the second zone if the measured first ambient condition in the second zone is not equal to the initial first ambient condition in the second zone.

14. The method of claim 13 wherein the first ambient condition in the first zone is a temperature in the first zone.

15. The method of claim 14 wherein the first ambient condition in the second zone is a temperature in the second zone.

16. The method of claim 13 wherein the first ambient condition in the first zone is a humidity in the first zone.

17. The method of claim 16 wherein the first ambient condition in the second zone is a humidity in the second zone.

18. The method of claim 13 wherein the first ambient condition in the first zone is the pressure in the first zone.

19. The method of claim 18 wherein the first ambient condition in the second zone is the pressure in the second zone.

20. The method of claim 1 wherein the dryer is operated by a controller.
