发明名称 Process and apparatus for testing air flow through a dual-stage blow head
摘要 <p>Apparatus for testing air flow through a dual-stage blowhead (48) that includes an adapter block (12) with a blowhead cup (18) for releasably receiving a dual-stage blowhead. The adapter block (12) has a first block passage (24, 26, 28) for feeding test air to a first inlet (30) of the blowhead for conducting blow air to a parison, and a seeond block passage (34, 38) for feeding test air to a second inlet (40) of the blowhead separate from the first inlet for conducting finish cooling air. Air is directed from a common source separately to the first and second block passages, and air flow is measured in each path. When air flow through the finish cooling air path is less than a predetermined threshold, or less than a predetermined ratio with respect to the final blow air, this may indicate a need to redrill or otherwise rework the finish cooling passages in the dualstage blowhead. <IMAGE></p>
