Description

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention is further described in the detailed description which follows, in reference to the noted drawing by way of non-limiting examples of exemplary embodiments of the present invention, wherein:

The FIG. 1 shows, in a plan view, a detail of a transport belt constructed according to the invention.

Claims

1. A transport belt, comprising: a web material contact side having printing material thereon.

2. The transfer belt according to claim 1, wherein the printing material is comprised of printing ink or writing ink.

3. The transfer belt according to claim 1, wherein the printing material is provided on the web material contact side in a regular print pattern.

4. The transfer belt according to claim 1, wherein the printing material is provided on the web material contact side in an irregular print pattern.

5. The transfer belt according to claim 1, wherein a surface fraction of the web material contact side, printed with the printing material, is in a range from approximately 20% to 100%.

6. The transfer belt according to claim 1, wherein a thickness of the printing material is less than 50 μm.

7. The transfer belt according to claim 1, wherein an area of individual printing material segments of the printing material is in a range from approximately 0.5 mm2 to 5 mm2.

8. The transfer belt according to claim 1, wherein the transfer belt is adapted for use in machines for production of paper or paperboard.

9. The transfer belt according to claim 1, wherein the printing material generates local regions which have surface properties different from remaining surface properties of the web material contact side.

10. The transfer belt according to claim 1, wherein the printing material has surface properties which approximate a surface property of the transport belt after a run-in phase.

11. The transfer belt according to claim 1, wherein the printing material is in at least one of a dot pattern and a stripe pattern.

12. The transfer belt according to claim 1, wherein a size of individual print elements of the printing material is in a range of about 2 mm2.

13. The transfer belt according to claim 1, further comprising printing material on a side facing away from the web material contact side which interacts with the drive or guide rollers.

14. A transport belt, comprising: a web material contact side having printing material thereon provided in predetermined regions which comprise a surface fraction of the web material contact side in a range from approximately 20% to 100%,wherein surface properties of the printing material during a run-in phase approximates surface properties of the web material contact side after the run-in phase in the predetermined regions.

15. The transport belt according to claim 14, further comprising printing material on a side facing away from the web material contact side.

16. The transport belt according to claim 14, wherein the printing material is comprised of printing ink or writing ink.

17. The transfer belt according to claim 14, wherein a thickness of the printing material is less than 50 μm.

18. The transfer belt according to claim 17, wherein an area of individual printing material segments of the printing material is in a range from approximately 0.5 mm2 to 5 mm2.

19. The transfer belt according to claim 14, wherein the web material contact side which was exposed to web material during the run-in phase has different surface properties than the web material contact side which had printing material thereon provided in the predetermined regions.

20. A method, comprising: applying printing material to at least portions of a web contact side of a transport belt; andgradually wearing off the printing material during run-in phase of the transport belt by liquid contained in web material to be produced.

21. The method of claim 20, wherein surface properties of the printing material substantially match surface properties of the transport belt after the run in phase.

22. The method of claim 21, wherein the web material to be produced comes into contact with portions of the transport belt that do not have the printing material such that ultra-fine particles from the web material to be produced works into a surface of the transport belt where there is no covering of the printing material.
