(1) Note. An endless convolutely wound coil whose material is fed axially subjects each of the convolutions to move longitudinally requiring each convolution to move at a greater angular velocity than the adjacent outer convolution. Patents provided for here reduce the friction caused by the convolutions rubbing against each other by a tendency to drive each convolution or groups of convolutions at appropriately different speeds.

The mere recitation of a motor, drive means, or control means is not sufficient to warrant placement here. Sensor details alone are sufficient only when not provided for above.

(2) Note. An inclusive exception is made for a disclosure of: (a) a particular spool provided with a distinct hand grip that replaces a distinct frame; (b) a frame-supported, stationary spool on which the same material is to be hand wrapped replacing the typical drive mechanism; or (c) a drive mechanism mounted on a frame for winding and unwinding a material in which the inner convolution (e.g., a metal tape) serves in lieu of a distinct spool.

430	COMPOSITE ARTICLE WINDING:

This subclass is indented under the class definition. Apparatus or method for either (a) winding an elongated material directly onto a core to form a permanent product of manufacture comprising a core and one or more permanently retained coils or (b) one of a group of selected components of such a winding apparatus or method not provided for elsewhere and whose utility is peculiar to use in a winder as defined in item (a), which component is limited to a work holder, a material tensioner, guide or guard, a shuttle, or a machine frame.

(1) Note. This subclass and the subclasses indented hereunder provide for winding a product of manufacture in which the elongated material is wound on and, by disclosure, remains as a distinct coil in intimate contact with a core so long as the core remains with the winding apparatus. Article winding provided for here is distinct from (a) a storage package winding whose material is to be subsequently unwound or otherwise removed from the core, provided for elsewhere in this class; (b) winding with additional component or product modification (e.g., shaping, twisting, bonding, coating or nonwinding assembly) provided for in other manufacturing classes; or (c) wrapping components together or on an indefinite length core to form a textile strand, wire rope, or similar product provided in a textile class.

(2) Note. Guidelines for placement of an original patent directed to a winder or winding method with features appropriate to production of either an article or storage package and certain subcombinations within Class 242 is as follows: (a) a winder or subcombination appropriate to winding a storage package as well as an article can be properly placed as a storage package winder, which generally provides a more comprehensive breakdown, if the specific article is unclaimed and winding a storage package is considered to be a clear alternative (e.g., a winder distributing wire in layers on a core useful as a storage coil as well as an inductance coil); (b) a claimed work holder, material tensioner, guide or guard, or a frame subcombination, is properly placed with the appropriate article winder if the subcombination is peculiar to a provided article winder (i.e., not readily used for a package winder and not having general utility). Some examples proper for article winders are: (i) a tensioner for stressing a pipe, vessel, or other core rather than stressing the material for proper winding; and (ii) a holder, guide, or guard asymmetrically related to the coil to be wound in a manner invariably related to winding a slotted article, such as a ring or spheroid.

This subclass is indented under subclass 432. Subject matter wherein the winding mechanism includes a material dispenser (e.g., a nozzle) and a motion transmission means for causing relative oscillation and reciprocation between the material dispenser and the core for wrapping the elongated material about the projection.

(1) Note. Typically the compound movement involves the following four sequential motions to form a convolution: (a) an axial movement of the material dispenser through one of the slots to deposit material along one of the slots; (b) an arcuate movement about an end face of the core to align the material dispenser with a second slot; (c) a reverse axial movement of the material dispenser through the second slot to deposit the material along the second slot; and (d) a final reverse arcuate movement about the opposite end face of the core end to position the material dispenser at the initial point ready to form a second convolution.

Material distribution is achieved by relatively shifting either or both the material supply (e.g., a guide) and the take-up member during winding to vary the point of winding along the take-up member. By this shifting, the winding point on the take-up member can be repeatedly traversed in opposite, back and forth directions, typically in a reciprocating or oscillating motion parallel to the winding axis. A high ratio of traverse relative to rotation creates widely spaced convolutions useful in axial unwinding (e.g., for a weaving shuttle), whereas a low traverse/rotation rate is useful to create adjacent convolutions (e.g., for high volume, compact material storage).
