The support frame for a workpiece has legs (5, 6) at one end which are perpendicular to the sides (7, 8) of the frame and have anti-skid cups (10, 10') on their ends. Horizontal bars (13, 13') attached to the other end of the frame are bent at the end to form vertical legs (14, 14') which are also fitted with anti-skid cups (15, 15'). |
