Abstract

An apparatus for straightening material includes a first guide surface and a second guide surface spaced from the first guide surface. As the material is passed along the first guide surface and along the second guide surface, the first guide surface induces a first curl in the material and the second guide surface induces a second curl in the material. The amount of the first curl may be in proportion to the rigidity of the material to be straightened, and the direction of the first curl may be opposite to that of the second curl.
