  • Patent number: 6698241
    Abstract: Method and apparatus for pressing a parison. A parison mold is composed of neck tool halves and parison mold halves. A gob of molten glass had first been introduced through an upper loading orifice into a cavity of the parison mold, while a pressing plunger was located in a lower loading position. An assembly consisting of a pressing element, a guide sleeve and a piston-cylinder unit was introduced into the loading orifice. Subsequently the pressing plunger was raised from its loading position into the illustrated upper end operating position until its annular end face had moved into position against a stop surface of the neck tool. Following the preliminary pressing process a neck chamber in the cavity is still free from molten glass. It is only at this point that the pressing element exerts pressure on a base of the parison which is being produced. The molten glass is also pressed into the hitherto still free neck chamber of the cavity.

  • Patent number: 6079226
    Abstract: A hollow glass parison is formed by pressing a gob of molten glass in a mold cavity with a plunger which is moved in a linear direction by a leadscrew which is connected to the plunger and is driven by a servomotor. Actuation of the servomotor creates a rotation of the leadscrew which causes the plunger to advance in a linear direction from a first position until the plunger contacts the gob at a second position. The plunger then advances to press the gob in the mold cavity to form the gob into a parison. During movement of the plunger in the linear direction the position of the plunger is continually sensed with a position-sensing resolver which provides position information to a system controller which utilizes the position information to control the position of the plunger prior to contacting the gob in the mold cavity, the depth of plunger penetration into the gob of molten glass during pressing by controlling the pressing pressure, and the weight of the gob of molten glass.

  • Patent number: 4298371
    Abstract: In the manufacture of hollow glass articles such as bottles, a gob of molten glass is blown or pressed into a parison in a premold, the parison being then transferred to a final mold where it is allowed to reside for a period sufficient to equalize its temperature before being blown into its ultimate shape. During the latter step, another final mold receives a parison meanwhile formed in the same premold. The two (or more) final molds associated with a given premold are mounted on a turntable for juxtaposition with the premold preparatorily to each transfer step.

  • Patent number: 4293327
    Abstract: A method for manufacturing glass bottles is disclosed which includes consecutively delivering gobs of molten glass into a blank mold, forming each gob into a parison, transferring the parisons alternately into at least two sets of blow molds, allowing said parisons to reheat, and expanding the parisons in the blow molds. The sets of blow molds reciprocate along a substantially vertical path. A first position where the parisons are alternately received by the blow molds and blown containers removed is located on the vertical path. The parisons are expanded and cooled in the blow molds by blowing them out or by applying a vacuum, or a combination of those means at a second position on the vertical path.

  • Patent number: 4255177
    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.

  • Patent number: 4255179
    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.

  • Patent number: 4255178
    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.

  • Patent number: 4191548
    Abstract: Method and apparatus for forming glass containers by the blow and blow process in which a parison mold and blow mold are positioned relative to each other, such that parisons can be transferred by an invert arm. The parisons are formed with their necks down in the parison mold from a charge of glass delivered thereto, and vacuum is applied to the neck mold to settle the molten glass in the neck mold about a special neck pin to thereby form the finish portion of the container. The neck pin is pulled and counterblow of the charge into parison form is accomplished and the parison is transferred from the parison mold to the blow mold where it is expanded into final shape. The parison mold is coated with a "solid film lubricant" which provides a surface that has an insulating effect and requires less "swabbing" over its useable life.
