In a glassware forming machine the baffle or settle blowhead on the blank side, as well as the final blowhead on the blow side of a typical Hartford I. S. machine, must be aligned and mated with the blank, or blow mold respectively, before blow air can be directed into the mold. The blowheads are arranged on a carrier, which is moved into position above the molds, and differences in the vertical heights of the molds, or of the vertical positions of the blowheads, are accommodated within each blowhead and its associated mounting so that an equalized closing force is attainable between the blowhead and its mating mold. In the triple gob configuration disclosed herein each blowhead is provided with an annular piston and air pressure is provided to one side of the piston for achieving a predetermined closing force on each associated blowhead. This closing force is achieved without interfering with the delivery of blow air to the blowhead and thence to the interior of the mold.
