Abstract
In a blow molding apparatus where a plurality of sets of molds are mounted on a wheel rotatable about an axis and the molds are moved toward and away from one another to enclose a parison and the parison is blown to the confines of the cavity between the mold sections as the wheel rotates by the application of air, an apparatus for controlling the application of the air comprising a valve assembly associated with each set of molds on the wheel and comprising a valve which is opened and closed to control the flow of air to the mold. The valve assembly includes a rotatable cam for moving the valve to open and closed positions, a starwheel associated with the cam, and a first actuator mounted at a first position along the path of the wheel for engagement with the starwheel to rotate the cam and open the valve and a second actuator mounted at a second position along the path of the wheel for engagement with the starwheel to rotate the cam and close the valve.
