(under subclass 401) Device including means for urging the
work toward the work-moving means.
(1) Note. Where a patent discloses a pressing member cooperating in a feeding function (as, e.g., an idler roll of a feed couple), the patent (to be placed as an original herein) must claim the pressing member in terms of its pressing function (as by naming it "a presser roll") or claim additional structure effective to urge or permit urging of the presser toward the feeding means.
(2) Note. Included in this subclass are patents in which the pressure between the presser assembly and the work-moving means is adjustable. Thus patents claiming a feed couple, or equivalent term, (characterized by structure including two rolls between which, and in tangential contact with, the work is moved by the rolls) and also claiming means to adjust the pressure between the rolls, will be included in this subclass.
SEE OR SEARCH THIS CLASS, SUBCLASS:
475+, for similar structure in which a member presses work to a movable work-support, which work-support is not claimed as the work-mover.
