DEFINITION

Classification: 83/263

(under subclass 202) Device which incorporates means to assure, in connection with each starting or stopping of the work, the feeding or advancement of a predetermined length of work or the confinement of the rate of change of speed of the work to a desired range.

(1) Note. This subclass does not include adjustment of work-feed increment, as such, for which see subclasses 241+, supra.

(2) Note. A work-feed means as defined in this subclass is commonly used, for example, to prevent undesired, accidental, or unauthorized advance of the work during a dwell period, or to assure the full extent of advance of the work at each cycle, or to avoid damage to or inaccurate advance of the work caused by sudden starts and stops of the work-feed means.
