DEFINITION

Classification: 242/437

On irregularly shaped core:

(under subclass 430) Subject matter comprising a winding mechanism that is driven in a manner particularly adapted to accommodate a core having a complex winding surface, particularly an adaptation to variable winding rates due to (a) a noncircular winding surface cross-sectional or lengthwise of a core or (b) special distribution patterns appropriate for a core having longitudinally curved, offset, or separated winding surfaces.

(1) Note. These subclasses provide for winding onto an irregularly shaped core significantly deviating from a right circular cylinder due to an overall formation or accommodation of a special projection or aperture other than a common helical groove. However, creation of an irregular winding having an atypical distribution pattern is provided for elsewhere.
