ABSTRACT:
A machine automatically closes flip-top caps and tests their covers for proper opening and closing force. The machine has a pair of superimposed turntables separated by a wheel, the turntables and wheel turning as a unit about a common axis. The wheel has a plurality or pockets distributed around the periphery thereof to receive the open flip-flop caps after they are molded. The pockets are adjustable in size to accommodate caps of different diameters and heights. Cap gripping assemblies associated with each pocket firmly grip the cap to resist integral and vertical displacement of the cap. At least one and, in a preferred embodiment, both of the turntables have actuators positioned near each pocket on the wheel. Cams surround the turntables to raise and lower the actuators at selected locations. As the actuators raise and lower, the covers are flipped over to close the caps. Selected forces are applied through the actuators and corresponding cap opening fingers to reopen and reclose the covers. Covers which fail the force tests are separated from caps which pass the force tests.
