D06J - Definition 
Definition statement
This subclass covers:
Methods for pleating, kilting, or goffering textile fabrics or wearing apparel including of mechanical or physical processing with or without using heat, steam or treatment composition and also the combination thereof
Pleating is a method of an arrangement of fold by doubling the material upon itself and then pressing it into place 
Kilting is a method of a perpendicular arrangement of flat, single plaits, each plait being folded so as to cover half the breadth of the preceding one (generally to make three thicknesses of stuff), as on kilt. A system of pleating a kilt in which one full sett of the tartan pattern is taken up in each pleat, resulting in a reproduction of the pattern across the back of the kilt. Box pleats or knife pleats are used for pleating a kilt. 
Goffering is the process of creating frills in textile fabrics or wearing apparel so that they were evenly and finely gathered, e.g. make wavy by means of heated goffering iron, or other forms of goffers by pressing or stamping with a patterned tool 
Apparatus for pleating, kilting, or goffering textile fabrics or wearing apparel such as fabric folding mechanisms, pleat forming devices, pleating machines, including kilting machines, pressing patterns, ironing devices specially adapted for forming goffers or pleats, e.g. fluting irons, pleating irons, goffers 
Forms of pleats or the like, e.g. accordion pleats, kilt pleats, box pleats, goffers. 
Herringbone goffer pattern
Relationship between large subject matter areas
Between subclass D06J and subclasses D06B, D06C, D06F and D06M can be used multiple classification.
When classifying methods or apparatus for pleating, kilting, or goffering textile fabrics or wearing apparel subclass D06J can be used together with subclasses
- D06B or D06M if different kinds of particular treatment of textile fabrics or wearing apparel are applied before or during making pleats;
- D06C if the treatment of textile fabrics or wearing apparel is applied after making pleats, e.g. such finishing treatment as setting covered by D06C 7/02 or pressing or ironing covered by D06C 15/00; and
- main group D06F 71/00 that partially covers apparatus for forming pleats or gofers since the part of subclass D06F under the Guide heading "Ironing; Pressing" (D06F 61/00 - D06F 79/00) covers general aspects of ironing or pressing apparatus, mostly used for smoothing or removing wrinkles from clothes, linen or other textile articles but as well the aspects of special purpose, e.g. for forming pleats or gofers (group D06F 71/00).
