PCT No. PCT/EP95/00635 Sec. 371 Date Aug. 1, 1996 Sec. 102(e) Date Aug. 1, 1996 PCT Filed Feb. 22, 1995 PCT Pub. No. WO95/23047 PCT Pub. Date Aug. 31, 1995A support for flat workpieces for program-controlled machines includes a plurality of workrest rails which are movable along a first machining axis. Each workrest rail supports a plurality of vacuum chucks which are movable along the workrest rails and thereby movable along a second machining axis. Light bands which include a row of point sources of light are provided to indicate the selected positions of the workrest rails and the selected positions of the vacuum chucks on the workrest rails, thereby ensuring that the machining process does not interfere with or damage the vacuum chucks.
