(under the class definition) Apparatus and processes, for treating the outer periphery of a rubber tire casing by cutting, punching and/or rasping to produce a desired tread or traction effect in or on said periphery, or to prepare the periphery for treading or retreading.
(1) Note. This subclass is the locus of art relating to tire treading by a slitting or machining operation (except abrading, for which see Class 451, Abrading) which art (in the absence of this subclass) would ordinarily be classified in accord with the particular machining. Both apparatus and process are classified here on the basis of the article worked and the functional utility of said working operation.
(2) Note. Patents classified here as originals should always be cross-referenced in accord with the particular machining disclosed to other appropriate classes.
(3) Note. See section III of the class definition of Class 29, Metal Working, for the definition of machining and slitting.
(4) Note. This subclass does not include cutters, slitters or rasps, per se, even when such tools are set forth as applied to the treatment of rubber tires.
(5) Note. Included in this subclass, because of the general similarity to tire treading and resurfacing, are processes and devices provided for (A) the removal of mold flash from either tire periphery or bead, and (B) the reclamation of material from tires which does not necessitate the destruction of the tire. The disclosure under (B) may be limited to removal solely for the purpose of salvaging or reworking said material but unless the claims are so limited or restricted as to, of necessity, effect the destruction of the tire (so that it may not be regrooved or recapped) classification is proper in this subclass.
