Abstract

A grinding member is formed as a shape-elastic monolithic element and has at least partially a three-dimensional cell structure on a grinding surface of the grinding member. The grinding surface has a first abrasive agent. The grinding surface has at least partially an open-cell structure with open cells. The open cells of the grinding surface communicate via passages with cells of the interior of the grinding member. The cells in the interior of the grinding member that communicate via passages with the open cells of the grinding surface contain a second abrasive agent.

Claims

exact text as granted — not AI-modified
1 . A grinding member formed as a shape-elastic monolithic element and having at least partially a three-dimensional cell structure on a grinding surface of the grinding member, wherein the grinding surface comprises a first abrasive agent, and wherein the grinding surface has at least partially an open-cell structure with open cells.  
   
   
       2 . The grinding member according to  claim 1 , wherein the open cells of the grinding surface communicate via passages with cells of an interior of the grinding member.  
   
   
       3 . The grinding member according to  claim 2 , wherein the cells in the interior of the grinding member that communicate via passages with the open cells of the grinding surface comprise a second abrasive agent.  
   
   
       4 . The grinding member according to  claim 3 , wherein the first abrasive agent and the second abrasive agent are different.  
   
   
       5 . The grinding member according to  claim 3 , wherein at least one of the first and second abrasive agents is comprised of abrasive particles.  
   
   
       6 . The grinding member according to  claim 3 , wherein at least one of the first and second abrasive agents is fixed on the cell structure by a resin.  
   
   
       7 . The grinding member according to  claim 3 , wherein the grinding member is impregnated with a scouring agent.  
   
   
       8 . The grinding member according to  claim 1 , wherein the first abrasive agent comprises abrasive particles.  
   
   
       9 . The grinding member according to  claim 1 , wherein the first abrasive agent is fixed on the cell structure by a resin.  
   
   
       10 . The grinding member according to  claim 1 , wherein the monolithic element is comprised of a foam material.  
   
   
       11 . The grinding member according to  claim 1 , wherein the monolithic element is comprised of a plastic material.  
   
   
       12 . The grinding member according to  claim 1 , wherein the monolithic element has an air permeability of at least 1,500 liters per square meter and per second.  
   
   
       13 . The grinding member according to  claim 1 , wherein the monolithic element has a compression hardness of at least 2 kPa.  
   
   
       14 . The grinding member according to  claim 1 , wherein the monolithic element has a thickness of at least 1 mm.  
   
   
       15 . The grinding member according to  claim 1 , wherein the monolithic element is produced as a rolled-up web.  
   
   
       16 . The grinding member according to  claim 1 , further comprising a support material, wherein the monolithic element is attached to the support material.  
   
   
       17 . The grinding member according to  claim 16 , wherein the support material is comprised of a fabric.  
   
   
       18 . The grinding member according to  claim 1 , having several surfaces each providing a different surface treatment action.  
   
   
       19 . The grinding member according to  claim 1 , having several surfaces that are colored differently.  
   
   
       20 . The grinding member according to  claim 1 , wherein at least two of the grinding members are connected to one another by a layer.  
   
   
       21 . The grinding member according to  claim 1 , wherein the grinding member is disc-shaped.  
   
   
       22 . The grinding member according to  claim 1 , wherein the grinding member is cylindrical.  
   
   
       23 . The grinding member according to  claim 1 , wherein the grinding member is an endless band.
