Abstract (en)
[origin: EP2025420A1] The method involves transforming milling goods (14) by laterally displaced transforming areas (26-29) of rollers (22-25) in a transverse direction (W) into a spreading direction. The transforming areas of the rollers are deeply penetrated into the milling goods, which are widened to two side edges (17, 18) by the transforming areas. The spreading of the milling goods in a plane parallel to a roller axis is carried out by the transforming areas.
