Classification: 242/430


(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.


29, Metal Working,

33, 596+, 605, 618, 732+, and 779+ for winding an article that includes an additional nonwinding operation (e.g.,

shaping, assembly, or disassembly). 57, Textiles: Spinning, Twisting, and Twining,

3+, for winding to form a strand or wire rope, or winding with twisting or untwisting.

72, Metal Deforming, particularly

49+, 67+, and 127+ for winding or forming an elongated material into a coil by use of a bending device to stress the material beyond its elastic limit.

74, Machine Element or Mechanism,

20, 109 for a mechanical movement of general application.

140, Wireworking, particularly

34, 47, 71.5, 92.1, 92.2, and 124 for producing an article that includes winding wire disclosed as being bent beyond its elastic limit, most frequently evidenced by transfer of coiled wire relative to a mandrel on which it is wound.

156, Adhesive Bonding and Miscellaneous Chemical Manufacture, particularly

51+, 143+, 160+, 169+, 184+, 422, 425+, 443+, and 460 for winding combined with an adhesive bonding operation.
