Class Information
Number: 72/170
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 three concurrently-acting delta-arranged deflector elements
Description: Subject matter wherein the instrumentality comprises an integrated assemblage of three (or more) members acting at the same time on the moving work, wherein two members are located so as to be spaced along one side of the course of work movement and a third member is located on another side of said course.
