DEFINITION

Classification: 72/6.2

Metal deforming by use of roller or roller-like tool element:

(under subclass 6.1) Subject matter comprising a machine including, or method employing, a roller* tool or a roller-like tool* to deform work.

SEE OR SEARCH THIS CLASS, SUBCLASS:

28.2+, and 30.2, for other deforming by a roller or roller-like tool including control of the tool.

67+, for deforming by relative rotation between a workpiece and a tool, particularly subclass 75 for a spherical tool, subclasses 91+ for deforming by a roller or roller-like tool cooperating with an opposing concave surface, subclasses 110+ for a roller cluster, and subclass 124 for a roller cooperating with a work-spaced tool.

127+, for deflecting to deform metal which may include use of a roller or roller-like tool, particularly subclasses 162+ for "levelling" by use of relatively-inclined successive rollers, subclasses 178+ for "troughing" by use of a roller cluster, subclasses 179+ and 182 for use of a roller couple.

184+, for deforming by a "flying tool" that may comprise a roller or roller-like tool.

199+, for deforming by a roller or roller-like tool,

generally. 366.2, for a method of deforming by a disclosed (but not claimed) roller.

158, for rolling of metal parts combined with independent fusion bonding of the parts; and subclass 243 for simultaneous rolling and fusion bonding of the parts.

425, Plastic Article or Earthenware Shaping or Treating: Apparatus,

363+, for a press forming or press reshaping means for nonmetal including an endless (e.g., roll, etc.) forming surface.
