<p>An apparatus (10) for evaluating the wear resistance of a weatherstripping of the kind applied to a motor vehicle window frame wherein a window can movably engage the frame via the weatherstripping, the weatherstripping including a lubricating material, such as flocking, adhered to a base material, whereby the movable engagement can cause wear of the adhered lubricating material. The apparatus includes a clamping frame (26) and holding fixture (22) for holding a test strip (28) of weatherstripping, a wand (24) having a tapered nose portion (31), and a drive shaft (14), coupled to the wand and the holding fixture, for imposing a plurality of strokes of the wand nose portion upon the test strip. A weight block (44) or arm (22a) of the fixture coupled to the shaft via travel assembly (20), 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.</p> |
