DEFINITION

Classification: 57/200

STRAND STRUCTURE:

(under the class definition) Subject matter comprising indefinite length twisted structures made by the machines or process falling within this class and not elsewhere provided for.

(1) Note. To be placed in this subclass, there must be a

claimed twisted or twined constituent in the strand. Certain terms, such as plied, doubled, twined, roving, spun staple fiber yarn, etc., are accepted as denoting a twisted strand, and if used in a claim, classification in Class 57 is indicated, provided all other requirements therefore are met and provided that the disclosure of the patent does not clearly define the product as one devoid of strand structure (e.g., twisted, covered, and/or wrapped) as provided by this class.

(2) Note. A web or sheet product, distinguished only by the twisted, covered, and/or wrapped strand employed in its manufacture, is included in this subclass and the indented subclasses.

(3) Note. Search the appropriate subclasses of this class for processes and apparatus for making twisted strand structures.
