Class Information
Number: 72/235
Name: Metal deforming > By use of roller or roller-like tool-element > Plural roller-couples (e.g., successively or optionally usable) > Including successively-acting roller-couples > Comprising relatively-inclined successive couples
Description: Subject matter including a first-acting roller couple and a second-acting roller couple positioned so that, when viewed along the direction of work movement, the axes of the roller couples overlie in crossing relationship (i.e., their projections intersect on a plane perpendicular to the line of sight).
