Abstract
Abstract An apparatus for applying gasket material to the skirt of a gasket for the valve mounting cup of an aerosol container, comprises a mandrel (32) having a fixed portion (44) and a movable portion (42) which carries a sleeve of gasket material (30). A pin (38) locates the portion (44). An upper gripping member (46) closes on the portion (42) and moves downwardly to push the head of the sleeve over a mounting cup (34) following which a lower gripping member (48) holds the sleeve while the member (46) is released to allow the portion (42) to return and the pin (38) is retracted to allow movement of a cutter (50) to slice off a band of the sleeve. The sleeve is subsequently pushed home to lie partly within the mounting cup channel by a plunger (116). In another embodiment the upper portion of the mandrel is fixed and the lower portion is movable.
