Abstract (en)
[origin: EP2365114A1] The method involves using a light metallic material for manufacturing the opening roller housing (17), where the opening roller housing has a circular opening roller receiver (31). Openings are arranged in the circumferential wall of the opening roller receiver. The opening roller housing is so impinged with a sand blast medium in a finishing process that the surfaces (33,35) of the opening roller receiver is micro compressed and supports a roughness which ensures that no adhesion forces occur in area of the surface during the operation of the opening roller housing.
