DEFINITION

Classification: 242/473.4

Including wound package or empty spool handling:

(under subclass 470) Subject matter including a tending device facilitating continued winding by (1) removing a wound package and associated take-up member from a winding support, (2) placing a fresh package of wound material on an unwinding support, or (3) mounting or removing an empty spool on or from a winding or unwinding support.

(1) Note. The winding support and unwinding support are the structures mounting the package for winding or unwinding, respectively. They may be movable from one position to another (e.g., in a turret winder). The presence of a movable support is not sufficient for placement in this subclass.
