This machine is used in football training for both field players and goalkeepers. It can be programmed in such a way that certain types of shot are alternated successively or repeated continually. It is important here that the moving cup which catapults the ball out of the machine works precisely and reliably. Since training normally takes place outdoors, the individual components also need to be weatherproof. Maintenance times should be kept to a minimum too. The developers used three lubricant- and maintenance-free drylin® linear guide systems from igus® to position the cup, which, unlike conventional ball circulating systems, work with gliding elements.
