Abstract
A molding device for forming a liner on the inside surface of the top panel of a closure shell. The device has a molding tool disposed above an anvil which is relatively movable towards and away from the tool by an elevator mechanism. The molding tool includes a center punch. An annular bushing is positioned externally of the center punch and is movable over a predetermined range with respect to the punch. Resilient means are provided for urging the bushing upwardly with respect to the punch and a lowering mechanism is included for moving the bushing downwardly against the force of the resilient means.
