ABSTRACT:
A thin, relatively hard wiper is provided, the wiper including a blade defined by a pair of opposed substantially planar surfaces which are spaced less than 0.008-inches apart. The surfaces run parallel to one another, with each surface terminating in a wiping edge at a first end of the blade. To provide a blade of desired thickness, the wiper 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, minimizing manufacturing cost.
