(under subclass 13) Process which includes a step of severing a plurality of products from a workpiece, each of which products has an interfitting portion which lies within a recess of the other product, the product portions which define the cooperating interfitting portions constituting the parts of the whole of a common area of the workpiece, and at least part of the separation being effected along the lines of the interfitting portions.
(1) Note. The mere longitudinal separation of a web of indefinite length into two or more ribbonlike products by means of an undulant cut, or the mere transverse separation of a product from a web of indefinite length by means of an undulant cut, is not considered sufficient to bring the patent within this subclass but will be found below in subclasses 48 and 56.
