ABSTRACT:
In a table for supporting sheet material, such as cloth, in a spread condition while it is cut by a cutter the main structural component of the table consists of a panel having an upwardly facing support surface and made up of upper and lower sheets bonded to a core including at least one duct for supplying air at vacuum pressure or positive pressure to openings spaced longitudinally of the panel to supply vacuum or positive air pressure to selected parts or all of a material support surface defined by a bristle bed supported by and located above the upwardly facing support surface of the panel. Valves carried by the panel open and close the openings in the duct to selectively control the portion of the work material support surface to which vacuum or positive air pressure is applied.
