DEFINITION

Classification: 226/168

(under the class definition) Device having a circumambulating material contacting face, i.e., any given element of the face moves in a closed loop.

(1) Note. In this and indented subclasses are, for example, patents disclosing devices wherein endless belts and rollers engage and advance material.

(2) Note. A patent placed in this and indented subclasses may merely guide the material* relative to the advancing material* of the indeterminate length* apparatus.

SEE OR SEARCH THIS CLASS, SUBCLASS:

52+, for means engaging longitudinally spaced modifications in the material* where the prong means may move in a closed loop and engaging modifications in the material.

120+, for intermittent (interrupted) material*-mover where the gripper means may travel in a closed loop in which only a portion of the gripper travel effects intermittent material advance.

196.1, for a passive guide, for other than orbitally traveling material*-engaging surface(s), for the advancing material* of indeterminate length* apparatus. SEE OR SEARCH CLASS

16, Miscellaneous Hardware,

210+, for a roller guide for sash-cord.

242, Winding, Tensioning, or Guiding, for more than a nominal supply or take-up coil structure (e.g., a support for such a coil, a cooperative relationship between a tension or exhaust detector and reel driving or reel stopping means, etc.),

354, for a particular linear feeder* (e.g., capstan or sprocket, etc.) spaced from the supply or take-up coil, subclasses 364+for a unidirectional winding and unwinding apparatus that may involve storage, subclass 548 for particular guide or guard for convolute winding of material*, subclass 566 for an unwinding apparatus having a particular guide or guard, or subclass 615.2 for a residual locus for a rotatable material* guide or guard.
