Class Information
Number: 72/167
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 deflectors arranged to bend work longitudinally of direction of work-movement > Including thinning of portion of work-section
Description: Subject matter wherein the instrumentality comprises elements (a) having work-engaging surfaces extending transversely across the direction of movement of the work, and (b) engaging opposite faces of the work, and in which, as claimed or disclosed, the distance between the work-engaging surfaces is less at one side margin of the work than at the other side margin thereof, and also less than the original work thickness.
