Grinding device for creating surface structures

Abstract

A grinding device has at least one endless grinding belt guided over deflection elements in at least one direction of circulation (P3) and a press-on arrangement which is configured and arranged such that it exerts a force from the inside on the grinding belt in a press-on area. The press-on arrangement comprises a base body and at least one press-on element arranged on the side of the base body facing the inner side of the grinding belt. The at least one press-on element is connected to the base body via a Velcro or adhesive connection. The grinding device can be a component of a belt grinding machine.

         3 . The grinding device according to  claim 1 , characterized in that the press-on arrangement comprises a press-on beam which is configured and arranged such that it exerts a force from the inner side on the grinding belt in a press-on area, the press-on beam comprising a base body and at least one press-on element arranged on the side of the base body facing the inner side of the grinding belt. 
     
     
         4 . The grinding device according to  claim 1 , characterized in that the base body is firmly connected to or comprises a first hook and loop adhesive layer and that the at least one press-on element has or is connected to a second hook and loop adhesive layer on the side facing the base body. 
     
     
         5 . The grinding device according to  claim 4 , characterized in that one of the first or second hook and loop adhesive layers comprises a hook and loop non-woven layer, a hook and loop velour layer, fleece tape hook and loop layer, a hook and loop hook layer or a mushroom head hook and loop layer, wherein the hook and loop adhesive layer is preferably a metallic hook and loop adhesive layer or a plastic hook and loop adhesive layer. 
     
     
         6 . The grinding device according to  claim 4 , characterized in that the base body of the press-on belt comprises or consists of a fiber-reinforced plastic layer or a metal strip. 
     
     
         7 . The grinding device according to  claim 4 , characterized in that the base body of the press-on beam comprises or consists of a metal, a wood or a plastic profile. 
     
     
         8 . The grinding device according to  claim 1 , characterized in that the base body comprises a ferromagnetic material and that the at least one press-on element comprises a magnet. 
     
     
         9 . The grinding device according to  claim 2 , characterized in that the endless press-on belt is drivable by means of a drive unit, or that the press-on beam is movable by means of a drive unit for moving the press-on beam in a press-on plane. 
     
     
         10 . The grinding device according to  claim 1 , characterized in that a plurality of press-on elements are provided which can be freely positioned on the base body. 
     
     
         11 . The grinding device according to  claim 1 , characterized in that at least two press-on elements differ in shape, size and/or strength. 
     
     
         12 . A belt grinding machine for grinding a flat workpiece, in which the workpiece passes through the belt grinding machine in a predetermined direction of travel (P 1 ), having at least one grinding device according to  claim 1 . 
     
     
         13 . A press-on belt or press-on beam for exerting a force in a press-on area from the inside on a grinding belt of a grinding device,
