ABSTRACT:
An apparatus for straightening material includes a first guide surface and a second guide surface opposite the first guide surface. Pin (20) for pivoting the second guide surface is included, this operating to pivot the second guide surface toward the first guide surface and away from the first guide surface. A spring (22) for biasing the second guide surface toward the first guide surface is also included, with a variable rate characteristic resulting from contact of the spring with a post (34). The variable rate characteristic allows the second guide surface to pivot away from the first guide surface in proportion to a rigidity of the material to be straightened. Material of varying rigidities is passed between the first guide surface and the second guide surface and the apparatus straightens the material for subsequent processing.
