(under subclass 364) Subject matter in which the material wound on the support is moved axially relative to the support during operation while remaining on the support.
(1) Note. Changing the winding point (where the material being wound meets the support or body of wound material) is a different operation than the one provided for in this subclass. See the search notes below.
(2) Note. For placement in this subclass, there must be structure specifically designed to shift the material. Forcing of wound material axially by mere engagement with newly introduced material is not sufficient in absence of structure to force the new material axially.
SEE OR SEARCH THIS CLASS, SUBCLASS:
366.3, for a unidirectional winding and unwinding device in which the winding point is systematically changed during winding, (i.e., the material is traversed on the support).
365, for a unidirectional winding and unwinding device having a rotatable support onto which the number of turns of material wound is variable during operation in which material on the support is shifted along the support.
