DEFINITION
Classification: 28/
This class is (a) generic as to processes of or apparatus for the production of fabric articles or structures by the mechanical interengagement of fibers, threads or the like and (b) residual as to processes of or apparatus for the production and treatment of fabric articles or structures. This class also provides for processes of or apparatus for (a) treating fabric articles or structures in a manner not provided for elsewhere, (b) preparing and handling of a sheet of warp threads or pile threads up to and inclusive of its insertion into a textile product fabricating apparatus, (c) thread finishing or packaging not provided for elsewhere, and
(d) stripping bobbins of waste thread, and for subcombinations peculiar to the above which are not provided for elsewhere.

8, Bleaching and Dyeing; Fluid Treatment and Chemical Modification of Textiles and Fibers, appropriate subclass for methods of treating textile fabrics, threads, fibers and the like with a fluid to bleach, dye or chemically alter the treated material either, per se, or combined with a broadly recited textile operation.
19, Textiles: Fiber Preparation, appropriate subclass methods of or apparatus for the preparation of fibers for use in the manufacture of fabrics or thread-like structures. The combination of texturing and staplizing a thread-like structure will be placed in Class 19 if the texturing precedes the staplizing and is performed to enhance a characteristic of the fiber produced as a result of the staplizing operation.
26, Textiles: Cloth Finishing, appropriate subclass for the mechanical treatment of a running length of textile fabric to put it into a better marketable condition.
34, Drying and Gas or Vapor Contact With Solids, appropriate subclass for methods of and apparatus for drying textile structures.
53, Package Making, appropriate subclass especially 396, and 582+ for methods of and apparatus for the packaging of thread units with material other than a strand-like wrap and where no additional thread finishing operation is recited.
57, Textiles: Spinning, Twisting, and Twining, appropriate subclass for methods of or apparatus for treating and twisting a thread, yarn or the like, for texturing a thread, yarn or the like by a twisting technique, e.g., false twist, or for forming a composite yarn by means of an air jet where one strand is wrapped about another in either a continuous or discontinuous spiral wrap.
66, Textiles: Knitting, appropriate subclass for the fabrication of a textile product by the interlacing of yarn or thread in a series of connected loops and for such fabrication combined with "on the machine" treatment of the yarn, thread or the formed textile product.
68, Textiles: Fluid Treating Apparatus, appropriate subclass for apparatus for contacting a textile product with a gas or liquid in a manner not provided for elsewhere.
87, Textiles: Braiding, Netting, and Lace Making, appropriate subclass for methods and apparatus (a) for intertwining a plurality of strands to form a plait-like structure, (b) for intertwining or knotting a plurality of strands into an open meshed fabric, or (c) for forming a plurality of strands into an ornamental openwork fabric, and the products formed by such methods or apparatus.
112, Sewing, appropriate subclass for producing a thread interlaced textile structure by a thread stitching operation.
118, Coating Apparatus, appropriate subclass for apparatus for applying a coating material to textile products, including individual threads, other than a sheet of warp threads.
139, Textiles: Weaving, appropriate subclass for the fabrication of a thread interlaced textile product which is formed by arranging one set of threads transversely to another set such that each thread of one set lays above some and below the remainder of the threads of the other set and is clamped in place by this arrangement and for such fabrication combined with "on the machine" treatment of thread or yarn used in product fabrication or of the formed textile product.
156, Adhesive Bonding and Miscellaneous Chemical Manufacture, appropriate subclass, especially
148+, for the formation of a textile fabric or structure by securing a preform, such as a bat, mat, thread or yarn, to another preform or to itself by an adhesive bonding technique. Examples of the subject matter to be found in Class 156 are: forming a textile product by weaving or knitting and subsequently treating the component thread of the product to cause it to fuse or otherwise adhesively bind to itself or to another thread at the cross-over point, adhesively securing a backing member to a pile fabric formed by weaving, knitting or needling, etc.
162, Paper Making and Fiber Liberation, appropriate subclass for the fabrication or treatment of paper. 165, Heat Exchange, appropriate subclass especially
89+, for yarn heaters of the heat exchange type.
219, Electric Heating, appropriate subclass and especially
770+, and 469+ for yarn heating apparatus having specific electrical heater structure.
223, Apparel Apparatus,
12+, for felting machines which have means for forming hat structure, e.g., a brim. The mere felting of a parabolic,
conical or cylindrical blank will not exclude a patent from this class (28).
242, Winding, Tensioning, or Guiding, appropriate subclass for the winding of strand-like material onto a carrier and especially
472.8+, for a winding device combined with a guide means for combining a plurality of independent strands into a single untwisted entity which is subsequently wound upon a carrier.
264, Plastic and Nonmetallic Article Shaping or Treating: Processes,
103, for a plastic molding or treating operation combined with a step of twining, braiding, plying or twisting multiple elements about each other; subclasses 109+ for the process of forming a bat, mat or the like of randomly associated fibers which fibers are fused or adhesively bound to one another at their cross-over points; subclasses 165+ and especially subclass 168 for the extrusion or extrusion and subsequent treatment of a strand-like member; subclasses 280+ for the reshaping of previously formed elements of indeterminate length other than thread, yarn or the like, except that subclasses 288.4+ takes processes for stretching work of indeterminate length whether or not such work is thread, yarn or the like; and subclasses 342+ for the treatment of a unitary thread formed of distinct, diverse extruded polymeric components which are arranged to run the length of the thread in a side by side fashion and which each shrink at a different rate when treated, to effect distortion of the thread.
289, Knots and Knot Tying, appropriate subclass for methods or apparatus for securing the ends of flexible strand-like members by tying and for the product of such a tying operation. 419, Powder Metallurgy Processes, appropriate subclasses for processes of forming articles by uniting particulate material containing metal particles.
425, Plastic Article or Earthenware Shaping or Treating: Apparatus, appropriate subclass for the extrusion or extrusion and subsequent treatment of a strand-like member and especially
66, and 76 for the extrusion and subsequent elongation of a strand-like member and the imparting of an irregular denier to a strand-like member, respectively.
427, Coating Processes, appropriate subclasses for coating or impregnating processes combined with a broadly recited textile operation.
428, Stock Material or Miscellaneous Articles, appropriate subclass for a stock material product which is made by a
method or apparatus provided for in this class (28), where such a product is not elsewhere classified.
432, Heating,
8, and 59+ for methods and apparatus for heating running lengths of strandlike material, e.g., yarn, in a manner not provided for elsewhere.
