DEFINITION

Classification: 242/599

Spindle feature:

(under subclass 598) Subject matter wherein particular

significance is attributed to a characteristic of a mandrel (spindle) having a coil supporting surface intermediate opposite ends portions adapted to be supported by a base structure.

(1) Note. This and the indented subclasses serve as the location for a winding or unwinding mandrel (spindle, shaft, arbor, etc.) having opposite end support portions and an intermediate portion adapted to receive wound material directly or through a supporting spool or core, which mandrel can bear a close similarity to a spool but usually is detectable as a permanent or reusable component of a winding or unwinding device bearing a distinct relationship to that device.
