<p>The invention relates to a method and to a device, wherein a first blade-carrier head ( 13 ) is rigidly secured in an axial direction and counter to rotation to an axially fixed blade shaft ( 2 ), a second blade-carrier head ( 14 ) is arranged on an axially displaceable, play-free blade shaft ( 3 ) which is connected to the axially fixed blade shaft ( 2 ) by a drive connection such that the blade-carrier heads ( 13, 14 ) are disposed in an aligned manner on a plane enabling the blade gap adjusting device ( 4 ) to be displaced to a zero position from the blade shaft ( 3 ) which can be axially displaced in only one direction. The second blade-carrier head ( 14 ) is adjusted by rotating on the blade shaft ( 3 ) in such a manner that both of the blade-carrier heads ( 13, 14 ) form a gap which is equal to zero and that the second blade-carrier head ( 14 ) is axially secured to the blade shaft ( 3 ), in said position, and counter to rotation.</p> |
