structures 15 for the guide bars are also shown here however the disks 10 11 are somewhat differently arranged in relation to the center plane 24 of the stand the center plane 24 is shown in fig2 as well as in fig3 plane 24 extends particularly transversely to the respective plane of the drawings of fig2 and 3 however in fig3 the axes 25 and 26 of the disks 10 and 11 run at an angle of about 15 degrees to that plane 24 as stated earlier an angle of inclination of about 20 degrees should not be exceeded in fig2 there is a zero degrees inclination the diameters of the disks 10 and 11 are determined by agents in the diameter of the rolls 6 and 7 further parameters to be considered are the space requirements for bearings and drive structures including for example articulated shafts 27 and 28 fig3 for the disks 10 and 11 basically one wants to use as small guide disks as possible particularly in these cases in which the diameter of the stock to be rolled increases significantly the shown example is illustrative of this aspect any large diameter for the guide disks behind the plane 23 would provide an undesired.
