DEFINITION

Classification: 242/538

With coiled supply:

(under subclass 520) Subject matter wherein the supply is an unwinding coil adapted to furnish material to a winding take-up coil.

(1) Note. While significant spacing between distinct supply and take-up coils is typical, the coils may be closely concentric, as in a coil tightener where relatively loose convolutions of a supply coil are constricted to an inner take-up coil.
