528.~ Of discrete sheets or articles


DEFINITION

Classification: 242/528

Of discrete sheets or articles:

(under subclass 520) Subject matter wherein winding is accompanied by disposing plural, distinct elements (e.g., cut lengths of material, newspapers, packets, etc.) about the winding axis, usually trapped by a succeeding wound layer.

(1) Note. The distinct elements may be discrete nominally claimed articles carried by a length of the elongated material only to the extent that the articles jointly conform to a wound convolution and the length of material serves only as a temporary conveyance or retainer, or elongated material severed into individual lengths prior to winding, but not a homogenous length of material divided in part only (e.g., perforated).
