Class 492
ROLL OR ROLLER
Class Definition:
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.
(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.
D. Miscellaneous combinations including one or more rollers
