Abstract
A metal tubing rolling apparatus positions a metal tubing section between three Nylon rollers for bending into a desired curvature. The middle roller is adjustably mounted to be raised and lowered and to preset the degree of arc to be placed in the portion of the tubing section between the fixed rollers. A constraining mounting for the middle roller permits vertical travel of the middle roller while maintaining a coplanar relationship with the fixed rollers.
