A gasketing method is described that provides low-cost, precision gasketing of complex shapes, such as is needed on the flat end walls of a xerographic magnetic brush developer. Conventional gasketing provides die-cut gasket shapes as a separate part. This part must be attached to one of the two mating pieces. A second technique provides numerically-controlled application of a "bead" of gasket material to the part. The present technique consists of fabricating a template or mask containing the desired gasket shape defined as an elongated opening in the mask. The thickness of the mask determines the desired thickness of the gasket. The mask is positioned over the part by the use of locating features. Liquid gasket material is then applied to the part through the mask by rolling, squeeze or spray methods.
