Abstract

This invention relates to an apparatus and method for drying and/or restoring books and other materials which have been wet, wherein the wet and/or distorted materials are placed in a vacuum chamber and subjected to vacuum while being gradually and uniformly heated through the use of heat conductive supports. A compressive force is applied to the materials while they are being heated to straighten and restore the distorted materials.
