  • Patent number: 4908082
    Abstract: A method is disclosed for the in-situ repair of damaged filter cloths in solvent dewaxing filters. The damage that can be repaired can be either or both of tears or holes. The method comprises thoroughly washing the filter cloth in the area of the damage to remove wax and oil, applying a quantity of solvent resistant adhesive to the damaged area such that the area of treatment extends beyond the hole or tear and adhesive overlays onto undamaged cloth, inserting pre-cut portions of filter cloth into the damage so as to completely fill the hole or tear but not create a bulge or cloth buildup in the face of the filter cloth where required and, finally, and optimally applying a final coating of adhesive over the repaired area.
