DEFINITION
Classification: 492/
This is the generic class for a single device, not elsewhere provided for, which has a generally cylindrical work contacting surface which surface revolves about the longitudinal axis of the cylinder with rolling motion relative to the surface of the work. The device here classified includes only that part of the roll or roller structure and its support which is rotatably mounted except that a cover or a pad, per se, that is disclosed or claimed solely for or in combination with such a roll or roller is included herein. The device here classified may have more then a single roller as long as only a single side of a workpiece is contacted or treated during a single treatment cycle.
NOTES TO THE CLASS DEFINITION
(1) Note. The roll or roller herein classified is generally a treating or shaping device although this class is the generic locus for a roll or roller not elsewhere provided for.
(2) Note. A pair of rolls or rollers acting on different sides of a workpiece simultaneously is classified according to its particular function and is not included herein. See the pertinent references in References to Other Classes, below.
(3) Note. Incidental disclosure of a roll or roller, per se, may also be found in those classes and subclasses listed in References to Other Classes, below.
The Search Notes below include all subclasses that refer to rolls in the subclass title or definition. Those classes and subclasses include roll making, but not setting forth such subject matter in a particular subclass is generally not included. The search notes are labeled as follows:
A. Roll or other rotary body, per se: (1) Method of making roll. (2) Roll with working surface. (3) Other rotary body.
B. Roll pair with working surfaces: C. Other plural rolls or rollers.
