ABSTRACT:
In a sawing machine of the type having a plurality of press rolls to constrain a traveling workpiece a control system is provided to sequence the press rolls. The thickness of an incoming workpiece is detected as are certain positions of the workpiece. The detected information is utilized to raise the press rolls a predetermined distance above the top surface of the workpiece and to then lower the rolls after the leading end passes under the respective roll. Flexible biasing means are designed into the press roll positioning means in order to accept shock loading and thereby minimize lateral deviation from straight line travel.
