(under the class definition) Process or apparatus for severing a strip or strap from sheet material, in substantially continuous fashion, by relative rotation of a tool and work about an axis while moving toward or away from each other during the severing operation.
(1) Note. The line of severance described by the cutting operation of this subclass comprises a flat spiral in the plane of the sheet material.
(2) Note. The cutting tool is usually at a fixed point or location with respect to which point the work is moved.
(3) Note. The combination of spiral cutting (here classified) with winding and reeling (classified, per se, in Class 242, Winding, Tensioning, or Guiding) is to be found in this subclass.
(4) Note. A subsequent cutting, either to length or desired cross section shape, of the severed strip or strap will not bar classification here if otherwise within the above definition.
(5) Note. This subclass includes working of sheet material other than metal (e.g., rubber, cloth, leather, etc.) as set forth above to produce thongs, lacing, belting, etc.
