  • This has the meaning that for the injection molding process necessary cores, which ultimately the interior of the Fiber feed channel result after the manufacture of the rotor lid from the Form or the finished rotor lid can be pulled out again.
  • the casting process in particular the injection molding process, enables the Manufacture of rotor lids in large numbers, with the lid at the same time can be manufactured with low tolerances and yet inexpensively can.
  • Such a channel has the disadvantage that it is in the constructive design of its inner contour is significantly restricted.
