Abstract
An apparatus for evaluating the wear resistance of a weatherstripping of the kind applied to a motor vehicle window frame wherein a window can moveably engage the frame via the weatherstripping, the weatherstripping including a lubricating material, such as flocking, adhered to a base material, whereby the moveable engagement can cause wear of the adhered lubricating material. The apparatus includes first structure for holding a test strip of weatherstripping, a wand having a tapered nose portion, and second structure, coupled to the wand and first structure, for imposing a plurality of strokes of the wand nose portion upon the test strip. Third structure, coupled to the second structure, is for adjusting the amount of force with which the wand nose portion is sought to be imposed upon the test strip during the plurality of strokes. The wand is a thin, flat and elongate glass part having a tapered nose portion.
