<p>A thin, relatively hard wiper (10) is provided, the wiper (10) including a blade defined by a pair of opposed substantially planar surfaces (16a, 16b) which are spaced less than 0.008-inches apart. The surfaces (16a, 16b) run parallel to one another, with each surface (16a, 16b) terminating in a wiping edge (18a, 18b) at a first end (12a) of the blade. To provide a blade of desired thickness (T), the wiper (10) is formed from a polymer having a modulus of elasticity within the range of between 100,000-psi to 5,000,000-psi. Such polymers are commonly available as sheet material, allowing for stamp-forming of the wiper (10), minimizing manufacturing cost. <IMAGE></p> |
