Clothing for a machine for producing a fibrous web

Abstract

Clothing in a machine for producing a fibrous web, for example a paper, board or tissue web, from a fibrous suspension. The machine has a wet end, a press section and a drying section and in each case there is clothing in the wet end, the press section and the drying section in order to guide the fibrous web. The clothing has integrated into the clothing at least one means for picking up and/or forwarding data about the clothing or the environment of the clothing.

1 . Clothing used in a machine for producing a fibrous web, for example a paper, board or tissue web, from a fibrous suspension, the machine comprising a wet end, a press section and a drying section and in each case there being clothing in the wet end, the press section and the drying section in order to guide the fibrous web, wherein the clothing comprises at least one of a means for picking up and a means for forwarding data, the data comprising information about at least one of the clothing and the environment of the clothing.  
   
   
       2 . The clothing of  claim 1 , wherein at least one of microsensors, data loggers and transponders are incorporated in the clothing.  
   
   
       3 . The clothing of  claim 1 , wherein the at least one means for picking up and for forwarding data is integrated into a control loop belonging to the machine and generates signal variables for a controller.  
   
   
       4 . The clothing of  claim 1 , wherein the at least one means for picking up and for forwarding data are arranged in in at least one of the transverse direction over the width of the clothing, diagonally over the width of the clothing, and in the longitudinal direction of the clothing.  
   
   
       5 . The clothing of  claim 2 , wherein the transponders transmits at least one of the number of circuits of the clothing, the position of the clothing, the distortion of the clothing, the length of the clothing, the width change of the clothing, the synchronization of drives within the machine, and data relating to product identification.  
   
   
       6 . The clothing of  claim 2 , wherein the microsensors generate values of at least one of pressure pulses, pressure pulses from a press nip in the press section, wear pulses, wear pulses as values of pressure, wear pulses as values of conductivity, temperature profiles, temperature profiles in the drying section, electric fields, charge potentials, and force extensions.
