Transport belt

Abstract

A transport belt, in particular for machines for the production of web material such as paper or paperboard. The transport belt includes a web material contact side having a substantially smooth unstructured web material surface and having printing material thereon.

1 . A transport belt, comprising:
 a web material contact side having a substantially smooth unstructured web material surface and 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 mm 2  to 5 mm 2 . 
   
   
       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 mm 2 . 
   
   
       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.
