A take-up spool for winding a filament under tension, e.g. preparatorily to its passage through a heating tunnel or other treatment zone, has a core bounded by a pair of cheeks which bracket two parallel rollers freely supporting the core through the filament body being wound thereon. At least one of the rollers is driven to rotate the spool; the other roller may be transversely movable to increase the gap between the rollers for letting the loaded spool drop onto a conveyor or into a receptacle.
