Nach erfolgtem Anspitzvorgang werden die jeweiligen Walzenpaare durch eine nicht gezeigte hydraulische Einrichtung abgeschwenkt.knife, should preferably be determined empirically and depends in particular on the material to be processed Rolled stock and its diameter. As can be seen for wave 4 ', the waves are multiple stored in devices 8 and have a disc 9, which serves to balance the eccentric to compensate for bearing pairs of rollers. After the sharpening process, the respective Pairs of rollers pivoted away by a hydraulic device, not shown.
