DEFINITION

Classification: 198/780

(under subclass 618) Apparatus wherein the conveyor comprises one or more parts or roller means which will rotate about an axis when influenced to do so by a source of power, and thereby cause movement of a load directly supported by and in contact with said rotated part.

(1) Note. Conveyors in this and indented subclasses may include an idler roller which may aid the power-driven roller in supporting the load conveyed. However, see subclasses 523+ for power-driven rollers and nonpower-driven rollers which act independently wherein one is active as a conveyor for the load, while the other is disengaged from the load.

SEE OR SEARCH THIS CLASS, SUBCLASS:

624, for conveyor means wherein the load is moved by being gripped between a plurality of driven rollers.

779, for rolls moved about an endless path and having means to axially rotate a roll or rolls as they move about the endless path.

SEE OR SEARCH CLASS 19, Textiles: Fiber Preparation,

24, and indented subclasses, for a series of rollers to crush fibers.

72, Metal Deforming,

199+, for sets of rolls used for metal deforming.

83, Cutting, subclasses having reference in their title to work or product moving, and particularly

156, 235, 259+, 268+, and 436.3.

193, Conveyors, Chutes, Skids, Guides, and Ways,

35+, for gravity-actuated rollers.

226, Advancing Material of Indeterminate Length, appropriate subclasses, for methods of and apparatus for feeding material without utilizing the leading or trailing ends to effect movement of the material.

384, Bearings, for bearings of general use.

406, Conveyors: Fluid Current,

70, for a fluid current conveyor combined with a line roller conveyor. 492, Roll or Roller, for a roll, per se, not elsewhere provided for, and see the notes thereunder.
