Click here for a printable version of this file

SECTION I - CLASS DEFINITION

This is the generic class for the treatment of textile fabrics subsequent to the fabrication thereof for putting them in better marketable condition.

Due to the similarity of the shearing of fur in the finishing of a fur skin to the shearing of the surface fibers or threads of cloth, particularly that of pile fabric, and the finishing of fur by shearing is included in this class.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

Due to the similarity of apparatus for the stretching of plastic film to apparatus for the stretching of fabric, the former has been placed in this class (26), along with the latter (see subclass References to the current Class, below). However, process for the stretching of plastic film is not in this class: rather it is in Class 264, Plastic and Nonmetallic Article Shaping or Treating: Processes, subclass 288.4 (see particularly subclass 290.2).
