    • A glassware forming machine blowhead arm assembly (12) includes a one-piece blowhead arm body (26) having at least one longitudinal air passage (36) and a plurality of lateral air passages (30-34) connected to the longitudinal passage. A blowhead chuck (44) is removably received in a first end of each lateral passage and a cap (60) is threaded into the second end of each lateral passage spaced from the associated blowhead chuck. A spring (66) is captured in compression between each cap and an associated blowhead chuck biasing the blowhead chuck in a direction out of the lateral passage and away from the cap. In an exemplary embodiment of the disclosure adapted for use in conjunction with so-called isolated finish cooling blowheads, there are first and second longitudinal air passages (28, 36) extending through the blowhead arm body separately from each other, and separate air inputs (18, 22) in the body respectively coupled to the first and second longitudinal passages. Each lateral air passage is separately connected to the longitudinal air passages, and the blowhead chucks have separate air passages for feeding blow air and finish cooling air to a blowhead (54) mounted in the chuck.

    • 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.
    • 用于测试气流通过双级吹风头(48)的装置,其包括具有用于可释放地接收双级吹风头的吹风杯(18)的适配器块(12)。 适配器块(12)具有用于将试验空气供给到吹风头的第一入口(30)的第一块通道(24,26,28),用于向型坯传导吹风空气,以及观察块通道(34,38) 用于将试验空气供给到与第一入口分离的吹风头的第二入口(40),用于进行终冷却空气。 空气从公共源分别引导到第一和第二块通道,并且在每个路径中测量空气流。 当空气流过精加工冷却空气路径时,相对于最终吹风空气小于预定阈值或小于预定比例,这可能表示需要对双台式吹风头中的精加工冷却通道进行重新钻孔或以其他方式重新加工。
