Abstract
A spool for optical fiber ribbon or other flexible media has an opening communicating with an interior of the spool in which a first end of a helical guide is located. The helical guide receives the ribbon from an exterior winding space to direct the ribbon to an auxiliary winding surface located outside one of the main flanges at an end of the spool.
Claims17
A device for winding an elongated material, the device comprising:
- a barrel having an outer surface;
- at least one flange secured to the barrel and having an outer surface, the outer surfaces of the barrel and the flange defining an exterior space for winding an elongated material, one of the barrel and the flange defining an interior and an opening, the opening communicating with the interior and with the exterior space for passage of an end portion of the elongated material therebetween;
- and
- a material guide having a first end located within the interior adjacent the opening and an opposite second end, the material guide defining a pathway for passage of the end portion of the elongated material between the first and second ends, the second end of the material guide located outwardly from the flange opposite the exterior space, at least a portion of the material guide pathway being substantially helical.

A spool comprising:
- a barrel having a hollow cylindrical wall defining opposite inner and outer surfaces;
- a pair of flanges secured to the barrel to define a winding space between the flanges, the wall of the barrel including an opening communicating with the winding space;
- and
- an insert having an outer cylindrical surface adapted for sliding receipt by the inner surface of the barrel wall, the barrel and the insert defining a substantially helical guide channel therebetween, the helical guide channel having opposite first and second ends, the first end of the helical guide channel located adjacent the opening in the barrel wall.

A spool for winding an elongated material, the spool comprising:
- a barrel defining a longitudinal axis and having an outer surface;
- a pair of flanges defining with the outer surface of the barrel an exterior space for winding a material,
- the barrel defining an interior and including an opening communicating with the exterior space and the interior;
- and
- a substantially helical guide channel having opposite first and second ends, the first end of the guide channel located within the interior adjacent the opening, the second end of the guide channel located outwardly from one of the flanges at an end of the spool.
