Abstract

Abstract 57 A fluid applicator wick which applies release fluids to a fuser roller adapted to fuse toner images to a copy sheet. The wick includes a fluid retaining material and a covering material. The covering material is in contact with at least one surface of the fluid retaining material and the fuser roller. The covering material (46) has at least a first layer (50) or fibers and a second layer (52) of fibers with a thin, loosely woven layer (56) of material interposed therebetween. At least a portion of the fibers of the first layer of fibers and the second layer of fibers are interlocked with the layer of loosely woven material interposed therebetween. The covering material preferably includes a third layer (54) of fibers, with a second thin, loosely woven layer (58) of material between the second and third layers of fibers.
