Abstract: A blank mold for an I. S. Machine is made up of a pair of opposed engaged blanks. When closed, these blanks have a top surface with an opening. The blanks have an inner surface defining the side wall of a parison which extends upwardly to a position a defined distance below the top surface of the blanks and a continuous, beveled surface connecting the top of the inner surface defining the side wall of the parison and the top opening of the blanks. A pair of funnels, each having a continuous beveled surface extending from a circular horizontally disposed top opening downwardly to smaller centrally located bottom opening, are interfit with the top of the blanks with the top opening of the blanks and the bottom opening of the funnel being coextensive.

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 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: A section of an I.S. machine for manufacturing glass containers. A gob of molten glass is delivered to a blank mold to be formed into a parison. The formed parison is then transferred to a blow mold so that an initial blowing operation can be performed to stabilize the parison. The blow mold with the stabilized parison is then transferred linearly to a final station where the parison is blown into the container.

Abstract: In an apparatus for manufacturing containers out of glass, a parison is formed from a gob of molten glass and is transferred to a mould having a cavity in the shape of the required container. Instead of the conventional blowing operation, the parison within the mould is heated so that the parison flows to conform to the shape of the cavity. The heating may be by a gas burner and air may be blown on to a neck portion of the parison to cool it during heating of the parison.

Abstract: A method and an apparatus for manufacturing hollow glass objects according to the press-and-blow process, in which a glass gob is shaped in a cooled preform mould into an elongate parison, the parison, while freely hanging at its neck portion, is then subjected to a thermal intermediate treatment and subsequently the parison is blown up in a finish mould to the desired hollow glass object and is simultaneously subjected to an upsetting operation, in such a manner that the blown-up hollow glass object at the part having larger transverse dimensions has a considerable wall thickness.

Abstract: A method and apparatus for manufacturing glass bottles and more specifically an apparatus and a method for forming parisons is disclosed. At least one blank mold defines a mold cavity having an opening at its upper end for receiving a premeasured gob of molten glass from a loading cavity member. A plunger having a volume of at least 15% of the volume of the mold cavity is completely extended into the mold cavity prior to the reception of the molten glass. The molten glass is moved downwardly from said loading cavity member into the mold cavity. Fluid force presses the molten glass against the walls of the mold cavity and against the extended plunger. The opening in the mold is closed by a baffle and the plunger retracted. Compressed air is applied through the neck of the parison to expand the parison outwardly against the mold cavity and a mold surface defined by the baffle means. The parison is then separated for further processing in the bottle making operation.

Abstract: An apparatus comprising a parison forming assembly and a final shaping assembly each having a mold, and a reheating and intermediate forming assembly provided between the two assemblies and having a cover or an intermediate forming mold for enclosing the parison in a confined space, the assemblies being associated with one another for sequential operation. Without prolonging the molding cycle time usually needed for the parison forming assembly and the final shaping assembly, unfinished parisons can be reheated sufficiently.

Abstract: An individual section of a multiple section glassware forming machine has three operating stations in spaced apart relation along the longitudinal center line of the section. Three independently operable transfer means move, respectively, a parison formed in an upright position at the first station to the second station, a further formed parison from the second station to the third station, and an article of glassware from the third station to a takeout position over a deadplate. The operating speed and rate of acceleration of each of the three transfer means is selected independently of the operating speed and rate of acceleration of both the other transfer means to effect its movement in the shortest practicable time compatible with the state of the glass during the movement of that transfer means.

Abstract: A glassware forming machine has three operating stations, in the first of which a parison is formed in an inverted position. First transfer means transfers a parison from the first station to a second station where the parison is released by the first transfer means in an upright position. A second transfer means receives the released parison at the second station and supports it for a selected time, after which the second transfer means transfers the parison to a third station, releases it and reverts to a position at the second station for receiving a further parison. A third transfer means operative independently of both the first and second transfer means removes an article of glassware from the third station and supports the glassware for a cooling period beyond the third station.

Abstract: An individual section of a multiple section glassware forming machine has three operating stations in spaced apart relation along the longitudinal center line of the section. A parison formed in the first station is transferred to the second station and released there by a first transfer means. A second transfer means which is operated independently of the first transfer means engages the parison at the second station and moves the parison to a third station in which an article of glassware is formed. By adjusting the time of operation of either transfer means relative to the other, the period of time during which the parison reheats may be changed without altering the relative timing of any of the machine functions which together make up the parison-forming cycle or the relative timing of any of the machine functions which together comprise the glassware forming cycle.

Abstract: Glassware forming apparatus includes a parison mold, a blow mold, a pair of neck rings for supporting glassware blanks, first and second invert arms for supporting the neck rings and first and second arbors for supporting the first and second invert arms, respectively. The invert arms support their respective neck rings for movement in a common vertical plane. The axes of the arbors extend generally parallel to one another and generally perpendicular to the common plane. The molds have parallel vertical axes lying in said common vertical plane. Apparatus is provided for shifting the arbors such that their axes move toward and away from one another during an operating cycle. Apparatus is provided for pivoting the arbors about their axes to move the neck rings in invert and revert arcs between the parison mold and the blow mold.
