ABSTRACT:
The present invention relates to a sharpening device for sharpening a wear edge of a rubber, plastic or polyurethane blade, such as a synthetic squeegee blade used in silk screening printing, comprising a housing with a base and an upper surface having a longitudinal clamp for clamping the blade during the sharpening operation. The sharpening device further comprises a cutting blade or knife which is removably held by a moveable carriage, both of which are located within a housing. The carriage is mounted on a block assembly and, preferably, carries a removable cutter holder. In operation, the carriage travels along the path of the wear edge of the squence blade, and the cutting blade or knife acts to cut off the wear edge of the blade and simultaniously treate a new edge. The cutting blade is mounted in an inclined position, with respect to the horizontal length of the wear edge, so that the upper beveled surface of the cutting blade is substantially parallel to the horizontal plane of the wear edge. The upper surface of the housing is designed to position the squeegee blade and align same with the cutting blade. The sharpening device according to the present invention is able to sharpen the wear edge of the blade quickly and easily while maintaining the fineness and flatness of said edge of the blade.
