156, Adhesive Bonding and Miscellaneous Chemical Manufacture,

62+, for laminating processes including the step of forming a lamina by bulk deposition of discrete particles.

264, Plastic and Nonmetallic Article Shaping or Treating: Processes,

109+, for processes for forming articles by uniting randomly associated particles. Where the claims recite only air laying of fibers the line with Class 264 is as follows: Sole disclosure is that the fibers are tacky or adhesive coated before air laying (Class 264).

Disclosure that air layed batt is subsequently rendered adhesive or tacky after air laying (Class 19).

Disclosure that the fibers may or may not be coated with adhesive before air laying (Class 19).

419, Powder Metallurgy Processes,

1+, for processes for forming articles by powder metallurgy with heating or sintering wherein the powder particles may be fibrous or filamental in form; and subclasses 61+ for processes for forming articles by uniting randomly associated metal particles which may be fibrous or filamental in form.

425, Plastic Article or Earthenware Shaping or Treating: Apparatus,

80.1+, for apparatus including air- felting means for forming self-sustaining bodies of particulate material.
