ABSTRACT:
A machine for leveling sheet metal strip without severing or marring the strip includes two stretcher frames, each having a set of jaws which clamp down on the strip, so that a segment of the strip is isolated between the jaws of the two frames. While the jaws grip the strip with enough compressive force to prevent the strip from slipping in the jaws, and yet not mark it, the frames are forced apart with enough force to stretch the isolated segment beyond its elastic limit for the entire width of the isolated segment, thus leveling the segment. Thereupon the parting force is released, and after the isolated segment has recovered its elastic deformation, the jaws release the strip, and the strip is advanced a distance not exceeding the length of the previously isolated segment. The procedure is then repeated until the entire strip has been leveled. The machine may be utilized in combination with a feeding machine which grips the leveled portion of the strip and advances it a preset distance.
