Abstract
A curling screw adjustment mechanism for changing the radial spacing of the curling screws of a lip curling machine forming a lip on a thermoformed plastic container such as a cup, in which the curling screws are each mounted on separate interlinked pivoted mounting plates which are moved in unison by adjustments of a threaded rod. The curling screws are also cooled by indirect contact with a cooling liquid circulated through separate aluminum arbors on which the stainless steel curling screws are mounted to allow changing the curling screws without spillage of coolant.
