DEFINITION

Classification: 19/.51

(under subclass .3) Processes and apparatus in which the severing operation is combined with a subsequent overlapping of the stapled fibers to form a sliver, top or other longitudinally cohesive, substantially continuous product.

(1) Note. Mere rearranging, as by drafting, of the fibers of an already cohesive, substantially continuous stapled fiber product is not such overlapping as will of itself result in placement of an invention in this subclass. There must be a placing of severed fiber ends into overlapping relationship to form a cohesive product from individual fibers, bundles or web sections. (The mere fact, however, that a patent claims or discloses a drafting operation in addition to such overlapping will not keep the patent from

this subclass).
