Abstract:

A tape hub including a support portion defining a peripheral surface around an axis adapted to frictionally receive a cylindrical inner surface of a core wound with tape, and means on the tape hub for positioning a first edge of the length of tape wrapped around the core at either of two discrete tape edge positions axially with respect to the hub. The tape hub is useful on devices that adhere tape along one edge of masking material to afford selecting different amounts of overlap between the tape and the masking material. The tape hub can have a plurality of radially extending hub portions having spaces therebetween and axially extending ribs on the hub portions defining its peripheral surface with the peripheral surface being adapted to frictionally receive the cylindrical inner surface of cores of slightly different inner diameters.
