Method for producing a roll grinder with minimal gap dimensions between the running roller and the handle body

Abstract

A method for producing a roll grinder with two running rollers, a handle body arranged between the running rollers and can be rotated relative thereto, and at least one grinding or polishing surface. The method includes steps of: producing the handle body; measuring the handle body in order to determine the actual dimensions of the handle body; providing at least two differently dimensioned types of spacer elements, by means of each of which a different distance can be set between one of the running rollers and the handle body in the installed state of the roll grinder compared to at least one other type; selecting one of the types of spacer elements provided depending on the measured dimension of the handle body; and connecting the handle body to the running rollers to form the roll grinder while using at least one spacer element of the type selected.

         16 . A method for producing a roll grinder with two rollers, a handle body arranged between the rollers and rotatable relative thereto, and with at least one grinding or polishing surface, the method comprising:
 producing the handle body;   measuring the handle body so as to determine a dimension of the handle body;   providing at least two differently dimensioned types of spacer elements, each of which enables determination of a different distance between one of the rollers and the handle body in the assembled state of the roll grinder;   selecting one of the types of spacer elements depending on the measured dimension of the handle body; and   connecting the handle body to the rollers to form the roll grinder using at least one spacer element of the selected type.   
     
     
         17 . The method according to  claim 16 , wherein the handle body is made of plastic, metal, or wood. 
     
     
         18 . The method according to  claim 16 , wherein the handle body is made of plastic, metal, or wood in once piece. 
     
     
         19 . The method according to  claim 16 , wherein the handle body is made of wood, and a moisture content of the wood is at most 15%. 
     
     
         20 . The method according to  claim 16 , wherein the handle body is manufactured as a cylinder. 
     
     
         21 . The method according to  claim 16 , wherein the measured dimension is a distance between two parallel sides of the handle body. 
     
     
         22 . The method according to  claim 16 , wherein the rollers are made of plastic or metal. 
     
     
         23 . The method according to  claim 16 , wherein each of the rollers is connected, with the interposition of a spacer element of the selected type, to an axle so as to be rotatably mounted on or in the handle body. 
     
     
         24 . The method according to  claim 23 , wherein each of the rollers is non-rotatably connected to the axle. 
     
     
         25 . The method according to  claim 23 , wherein the axle is a stepped axle with a central section and two bearing sections stepped at the ends, and wherein a rolling bearing, one of the spacer elements, and one of the rollers are arranged on each bearing section. 
     
     
         26 . The method according to  claim 25 , wherein, for each rolling bearing the rolling bearing is axially supported on the central section or the spacer element is axially fixed between the rolling bearing and the roller. 
     
     
         27 . The method according to  claim 25 , wherein each rolling bearing is mounted on the handle body so as to be supported by an outer ring on the handle body or by a bearing sleeve arranged thereon. 
     
     
         28 . The method according to  claim 16 , wherein at least one of the rollers has an end face-side grinding or polishing surface. 
     
     
         29 . The method according to  claim 16 , wherein at least one grinding or polishing disc is attached to the roll grinder, the grinding or polishing disc having a grinding or polishing surface. 
     
     
         30 . The method according to  claim 29 , wherein the grinding or polishing disc is detachably mounted on the roller or an axle that the roller is connected to. 
     
     
         31 . The method according to  claim 16 , wherein each of the rollers has a rubber ring running circumferentially at an edge of the roller, which forms a running surface of the roller. 
     
     
         32 . The method according to  claim 16 , wherein the roll grinder is manufactured from a maximum of 14 components, the components comprising: the two rollers, the handle body, two spacer elements, an axle, two rolling bearings, two rubber rings, and at least one grinding or polishing disc. 
     
     
         33 . A method for producing a plurality of roll grinders by performing several times the method according to  claim 16 , wherein at least two handle bodies are produced, wherein each handle body is connected to two rollers to form a roll grinder, using at least one spacer element of the type selected on the basis of the measured dimension of the handle body, thereby maintaining the distance between each of the rollers and the handle body within identical tolerance ranges in all the roll grinders. 
     
     
         34 . The method of  claim 33 , wherein the distance between the handle body and each of the rollers is smaller than 0.5 mm.
