MASKING DEVICE HUB PROVIDING TWO POSITION TAPE SUPPORT

摘要

A tape hub (38) including a support portion defining a peripheral surface around an axis (A) adapted to frictionally receive a cylindrical inner surface of a core (20) wound with tape (19) and means on the tape hub (38) for positioning a first edge (23) of the length of tape (19) wrapped around the core (20) at either of the two discrete tape edge positions axially with respect to the hub (38). The tape hub (38) is useful on devices that adhere tape (19) along one edge (15) of masking material (12) to afford selecting different amounts of overlap between the tape (19) and the masking material (12). The tape hub (38) can have a plurality of radially extending hub portions (59) having spaces therebetween and axially extending ribs (40) on the hub portions (59) defining its peripheral surface (61) with the peripheral surface being adapted to frictionally receive the cylindrical inner surface of cores (20) of slightly different inner diameters.
