DEFINITION

Classification: 242/365.6

Fixed number of windings on winding surface (e.g., positive feeder):

(under subclass 364) Subject matter constructed so that the number of turns of material on the support cannot vary during normal operation.

(1) Note. For placement in this subclass there must be structure or corresponding method steps present for maintaining the material in a path on the support such that there is no substantial change in the number of turns on the support. The structure may be a guide. The recitation of a positive material feeder with disclosure of a guide for maintaining the material path is sufficient to warrant placement of the original in this subclass.

(2) Note. Changes in the number of turns of material on the support during the initial introduction of material onto the support or on removal of material (e.g., after depletion of a material supply) are disregarded.
