Class Information
Number: 72/162
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") > Including relatively-inclined successive rollers
Description: Subject matter including a first-acting roller* and a second-acting roller positioned so that, even viewed along the direction of work movement, the axes of the rollers overlie in crossing relationship (i.e., their projections intersect on a plane perpendicular to the line of sight).
