Apparatus for checking the profile of a sheet and comparing measured data with that data from measurement of a standard. The apparatus includes a frame, a plurality of studs on the frame providing three support locations for the sheet, a plurality of reference stops spaced along two adjacent sides of the frame and structure along opposite sides for moving a sheet into a centered position at the stops and measuring structure for measuring the profile of the sheet at a centered position. The sheet may be held at the centered position to immobilize it during measurement and the apparatus may be located along a production line including structure for moving a sheet to the frame and removing the sheet from the frame.
