         5 . The method as claimed in  claim 4 , wherein the speed is specified to be approximately constant or the speed is specified from a speed characteristic. 
     
     
         6 . The method as claimed in  claim 4 , wherein the speed is directed in a direction opposite to an unwinding direction. 
     
     
         7 . The method as claimed in  claim 5 , wherein the speed is directed in a direction opposite to an unwinding direction. 
     
     
         8 . The method as claimed in  claim 1 , wherein the torque value is ascertained via the torque balance with a counteracting tensile force component and an identically acting inertia component. 
     
     
         9 . The method as claimed in  claim 1 , wherein the winding material speed is ascertained via geometric information relating to the winding body.

         11 . The method as claimed in  claim 3 , wherein the torque limit is controlled in real time. 
     
     
         12 . The method as claimed in  claim 8 , wherein a tensile force or a tensile force characteristic is specified for the tensile force component. 
     
     
         13 . The method as claimed in  claim 8 , wherein an inertia is specified, which is derived from a CAD system and specified, or is measured for the inertia component. 
     
     
         14 . A control unit for a brake roller for winding a winding material onto a winding body, comprising:
 a processor; and   memory;   wherein the processor is configured to:
 ascertain a torque value via a torque balance of the brake roller in dependence on a winding material speed; and 
 specifying the ascertained torque value for a drive of the brake roller. 
   
     
     
         15 . A computer program, comprising commands stored in memory which, when executed by a computer, causes the computer to perform the method as claimed in  claim 1 , wherein the computer program is executed on a virtual controller.
