(under the class definition) Apparatus including means to impart an impermanent change of shape (i.e., within the elastic limit) to work and to hold the work in that shape during the cutting operation.
(1) Note. This subclass includes devices which deform the work, as above defined, wherein such deformation is prerequisite to effect predetermined line of cut; that is to say, the desired cut could not be effected in the absence of the deformation while operating the machine in the intended manner.
(2) Note. Means for compressing, or stretching, a resilient workpiece and subsequently cutting a circular opening in same to impart an elliptical product surface configuration thereto upon release of the deforming forces would be properly placed in this subclass.
