Class Information
Number: 72/160
Name: Metal deforming > By deflecting successively-presented portions of work during bodily movement thereof (e.g., for coiling, levelling, curving or troughing material in movement) > By use of deflected arranged to provide longitudinally undulating path for work (e.g., "leveling")
Description: Subject matter wherein the instrumentality includes a plurality of deflectors* positioned along the path of moving work in offset relationship, each of which deflectors forces each successively presented portion of work from one direction into another direction in an arc extending partially around an axis-of-bend* that is disposed transversely of the path of work movement.
