DEFINITION

Classification: 242/364.6

Variable number of windings on support:

(under subclass 364) Subject matter in which number of turns or loops of material on the support is caused or permitted to vary during operation, i.e., the rates of winding and unwinding onto the support may be unequal.

(1) Note. For placement in this subclass, a patent must recite an element, such as a flyer that places material onto the material support or a guide that removes material over an end of the support, that enables material to be supplied to or removed from the support at a rate independent of the rate at which it is removed or supplied.
