Abstract: A method and a machine for the production of hollow glassware articles, by the blow-and-blow, press-and-blow, press-and-blow paste mold and direct-press processes in a glassware forming machine including single or multiple machine sections each having single or multiple-cavity, comprising: forming a parison in an inverted orientation, into a blank mold and a first transferable and open-able neck ring mold held by an inverting apparatus having a first and a second diametrically opposed arms, each arm holding a transferable and open-able neck ring mold; inverting the parison held by the first transferable and open-able neck ring mold, by rotating the first arm 180° to an upright orientation at an intermediate station, while the second arm with a second transferable and open-able neck ring mold is simultaneously placed at the parison forming station; transferring the first transferable and open-able neck ring mold holding the parison in an upright orientation, from the intermediate station, to a blow mold statio

Abstract: A neck ring guide for aligning neck ring sections in a glassware forming machine has a center body and a pair of spaced parallel runners coupled to the center body for receipt in guide slots in the neck ring sections. Keepers on the outboard sides of the runners retain the runners in the guide slots. Instead of keepers, the runners may be retained in the guide slots by roll pins on the neck ring sections engaged in retainer slots in the runners.

Abstract: The invention relates to a manufacturing apparatus for simultaneously making different hollow glass products having different gob sizes comprising at least one feed apparatus (12), that has at least one glass reservoir (14), at least one plunger (18a, b), and at least one appurtenant cutting device (24a, b) in the discharge from the reservoir, at least one conveying means (28) to successively transport at least one of the gobs discharged from the feed apparatus (12) into a plurality of shape-imparting units (32a–c) disposed next to each other for variously sized gobs, at least one controller (22) to control the plunger (18a, b) and the cutting device (24a, b) of the feed apparatus (12), the conveying means (28), and the shape-imparting units (32a–c), and said controller (22) controls the activity of the shape-imparting units (32a–c), the feed apparatus (12), and the conveying means (28) in coordination with the gob-size-specific processing time of the products in the shape-imparting units (32a–c) or their cyc

Abstract: A device and process for forming hollow glassware comprising producing solid glass blanks in a manufacturing line, storing the blanks, feeding the blanks to a manufacturing line for forming hollow glassware, preheating the blanks during the feeding step, supplying the preheated blanks to a heating stage, heating to form solid plastically deformable glass globs, transferring the glass gobs to a blow molding stage and blow molding the glass gobs supported by a bottom lifter in a blow mold.

Abstract: The method of the invention provides that a predetermined quantity of molten glass necessary for producing molded glass bodies according to the press-molding method is poured into a press mold prior to the insertion of the molding plug while the press mold is located in the press station, and that the molded glass body is removed after the molding plug is withdrawn from the press mold, with this mold likewise being located in the pressing station. This method renders a mold transport superfluous. The invention also relates to an apparatus suitable for executing the method, in which the molding plug can be pivoted laterally from its initial position located outside of the press mold about an axis extending transversely to the center axis of the molding plug.

Abstract: A machine for the production of glassware articles by pressing and blowing molten glass gobs fed from a glass gob feeder, comprises at least a blank mold and a corresponding pressing plunger, mounted at a stationary parison forming station, and four forming stations mounted around a 90.degree. indexed rotary carrier, each comprising a blow head, a neck ring and a blow mold, so as to rotate to a first forming position coinciding with the parison forming station, and to second, third and fourth forming positions spaced 90.degree. from each other, for reheating, blowing, and take out operations.

Abstract: A work table in a glass forming unit in apparatus for producing hollow glass articles has an orifice plate which is loosely fitted in a recess of the work table. Therefore, the orifice plate can be removed or mounted on the work table instantly while the orifice plate is firmly secured to the work table during the operation of the work table because the orifice plate expands by the heat of the handled molten glass to be friction-fitted in the recess. The orifice plate is formed of material having a coefficient of thermal expansion equal to, or relatively larger than, that of the work table.

Abstract: In the production of a glass vessel (such as a goblet) comprising a receptacle part (e.g. a goblet bowl) and a stand part (e.g. a stem with a base plate), the receptacle part is formed by pressing in successive moulds carried by a rotary table and the stand part is formed by injection moulding, being simultaneously united to the receptacle part. In carrying the invention into effect the mould for the receptacle part is charged from a feeder in free drop fall; the table is then rotated to bring the pressed receptacle part into register with an injection mould for the stand part, and an injection device, of which the injection mould forms part, is charged from the same feeder by way of a drop guide channel.

Abstract: This invention relates to a process for injection molding hydrosilicate glasses and apparati useful therefor. This invention is also concerned with apparati for mixing hydrosilicate glasses while in the fluid stage, i.e., when the hydrosilicate glasses have a viscosity between about 10.sup.2 -10.sup.9 poises. Finally, this invention describes materials demonstrating ready release of hydrosilicate glasses after contact in fluid form.
