The present invention is a de-warping apparatus for straightening a plate which is bent such that a centre portion thereof is higher than outer portions thereof. The apparatus comprises a plurality of rollers forming a support surface wherein the centre most rollers are mounted lower than the outermost rollers; an axle mounted above the rollers; a plurality of disks mounted for rotation about the axle, wherein the centre most disks have a larger radius than the outermost disks; and means for advancing the plate between the rollers and disks, whereby a greater downward force is applied to the centre portion of the plate than to the outer portions for de-warping the plate. |
