ABSTRACT:
A method of making an ironer roll cover which comprises impregnating a less than full-width longitudinal portion of a sheet of fabric with a liquid thermosetting resin and curing the resin. The unimpregnated portion of the fabric acts as a liner or padding for the impregnated portion, while the impregnated portion serves as the work-contacting surface. Because the liner portion and the work-engaging portion of the cover are integrally formed from a single sheet of fabric, no seam or stitching is required for joining the two portions. Thus, the unevenness caused by a seam is eliminated and manufacturing costs are reduced. In a preferred embodiment, liquid water is applied in a narrow band between the impregnated and unimpregnated sections of the fabric to achieve a less than full impregnation, thereby providing a transitional zone between the liner and the work-contacting portion of the cover.
