Description
Class 242 includes and is limited to:
(A) A process or apparatus for progressivelywinding elongated flexible material more than 360° aboutan axis of a take-up of restricted length, asin: (l) Unwinding and rewinding an information-bearingcarrier associated with a nominal work station such as that foundin a magnetic recorder/player, film projector, orcamera; (2) Forming an indefinite lengthof running material in loops to form a bundle of coils solely bywrapping or winding the material about a form (i.e., exclusiveof the use of a die or other shaping device); (3) Unidirectional windingand unwinding (i.e., simultaneouslywinding and unwinding material while turning in a single direction); (4) Reeling (i.e., repetitivelywinding and unwinding the same material); and (5) Windingby use of machine or implement for: (a) permanentlywinding material directly onto a core having distinct ends to createa composite article exclusively by winding; (b) windingmaterial, usually strand, in a helical or random mannerto form a storage coil for subsequent unwinding; or (c) windingmaterial, usually web, in a convolute manner toform a storage coil for subsequent unwinding;
(B) A storage coil formed exclusively bysuch a winding process or apparatus;
(C) A process or apparatus limited to unwindingmaterial from a storage coil;
(D) A process or apparatus for tensioning (i.e., applying orregulating longitudinal stress in a running material of indeterminateor indefinite length);
(E) A process or apparatus for guiding (i.e., establishing orconfining the path of movement of a running material of indeterminateor indefinite length); or
(F) A subcombination peculiar to winding, unwinding, tensioning, orguiding, such as a spool, spindle, mandrel, ordispenser.
