ARTICLE ENGAGED BETWEEN ENDS FOR ROTATION AND ADVANCEMENT:
(under the class definition) Apparatus comprising a driven means for engaging an elongated article between its ends and causing said article to advance along its longitudinal axis and simultaneously to turn about said axis, no other movements being imparted to the article.
(1) Note. The article must be longer than any individual engaging means in the direction of advancing movement. See Class 198, Conveyors: Power-Driven, subclass 780 for live roll conveyors in which long rolls advance an article while turning it.
