摘要： 1. A method for forming a parison for narrow neck glassware with an upright body mold defining a relatively wide open top cavity and a neck mold defining a relatively narrow opening for determining the finish of the parison and for supporting it, said method comprising the steps of depositing a gob of molten glass in the body mold cavity, supporting the neck and body molds with their opening and cavity in vertically space alignment while closing an intermediate mold to define an opening between and matching the bottom of the neck mold opening and the top of the body mold cavity, thrusting a plunger through the neck and intermediate mold openings into the cavity to press molten glass upwardly into both said openings to provide an initial form for the parison, stripping the plunger and body mold from the parison by relative vertical movement upwardly and downwardly, respectively, permitting the parison to reheat while suspended from the neck mold and thus to stretch downwardly, and removing the intermediate mold at a selected point in time during reheat.

摘要： An apparatus and method for making glassware by a press and blow technique wherein the pressed parison is formed in an upright mold construction. The said mold construction utilizes a relatively wide cavity body mold and a relatively narrow opening neck mold, and also an intermediate ''''transitional'''' mold which is placed between the neck mold and body mold when the parison is initially formed. The transitional or intermediate mold is opened after the parison has been formed to permit the parison to reheat and stretch before being placed in a blow mold or other final shaping mold where the parison is blown or otherwise expanded to the final size and shape desired for the article of glassware.
摘要翻译： 一种通过压制吹塑技术制造玻璃器皿的设备和方法，其中压制型坯形成为立式模具结构。 所述模具结构利用相对较宽的腔体模具和相对较窄的开口颈部模具，以及当初始形成型坯时，其位于颈部模具和主体模具之间的中间“过渡型”模具。 在形成型坯后，过渡或中间模具打开以允许型坯在被放置在吹塑模具或其它最终成型模具中之前再加热和拉伸，其中型坯被吹塑或以其它方式膨胀至所需的最终尺寸和形状 玻璃制品。

摘要： A method and apparatus for treating newly formed glassware as the ware is removed from a forming machine utilizing a transfer mechanism which holds the glassware in a suspended condition until the are is deposited on an output conveyor. The transfer mechanism moves the ware in the suspended conditio over a spray head which consists of a stray cup which periodically moves upwardly to surround the bottom of the glassware is exposure the base of the ware to a timed cooling and metal chloride spray. The newly formed ware is maintained in its suspended condition until is deposited on the conveyor to prevent distortion of the ware and bottom.
