Class Information
Number: 28
Name: Textiles: manufacturing >
Description: 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.
