ABSTRACT:
The machine has a base provided with three rollers between which cambered strip steel is passed to remove or reduce the camber therein. Two of the rollers are mounted extending above the top surface of the base along a longitudinal axis of the base. The third roller is mounted also extending above said top surface on a block which is slidable along a slot extending along the lateral axis of the base. The cambered strip steel is passed across the top of the base between the three rollers. A drive mechanism is provided to apply a force to the third roller which bends the cambered strip steel against the two rollers to remove or reduce the camber. Removable guide strips of a case hardened or other suitable metal are provided in the top as bearing members for the strip steel. The base may be fabricated of assembled components or cast as an integral member for cost economy.
