DEFINITION

Classification: 242/352

Simultaneous drive to supply and take-up coils:

(under subclass 349) Subject matter wherein the drive mechanism includes a drive input acting on both the supply and take-up spools at the same time (e.g., a single motor acting through a divergent transmission to each spool).

(1) Note. The drive input may tend to rotate the coils in the same or opposite directions.
