ABSTRACT:
In a machine tool having a base member, a table supported on the base member, on which a workpiece may be positioned to be machined, and a toolhead assembly supported on the base member, provided with a tool engageable with the workpiece positioned on the table for performing a work function relative thereto wherein the table and the toolhead assembly are displaceable relative to each other along a line of travel, an assembly for holding down a workpiece positioned on the table upon relative displacement of the table and the toolhead assembly along the line of travel generally consisting of at least one upper roller having an axis disposed transversely relative to the line of travel and engageable in rolling contact with an upper surface of a workpiece positioned on the table, a set of lower rollers each having an axis disposed transversely relative to the line of travel and engageable in rolling contact with an undersurface of the table and means supported on the base member and operatively interconnecting the upper and lower rollers for selectively drawing the rollers together into engagement with the workpiece and table therebetween whereby the workpiece will be urged into contact with the table and the rollers will be disposed in rolling contact with the workpiece and the table as the table and toolhead assembly are displaced relative to each other.
