GLASS FORMING MACHINE COMPRISING A SWABBING STATION AND METHOD
The invention refers to a glass forming machine which includes a blank station for forming a parison (14) from a gob of molten glass (9) and a blow station for forming the parison (14) into a container (26) and an invert mechanism (16) which can move a neck ring (5) from the blank station to the blow station by a rotary motion and which further includes a swab robot and a control device for the swab robot, wherein the control device is set up so that the swab robot can swab and thus swab the neck ring (5) when the neck ring (5) is in an intermediate position between the blank station and the blow station. Defects in the production of bottles can thus be avoided.
Method of fabricating a glass container, and a corresponding installation for performing the method
The invention relates to a method of fabricating a glass container, the method comprising a forming step of forming molten glass in order to obtain a semi-finished container (4) comprising a shell (5) presenting inside and outside faces (7, 8), a cooling step during which the semi-finished container is in a transient state in which the glass forming the outside face is sufficiently viscous for it not to deform under the effect of gravity, while the glass forming the inside face is sufficiently fluid to allow the inside face to deform under the effect of gravity, the method including a shaping operation while the semi-finished container is in the transient state, in which operation the semi-finished container is maintained for a predetermined time in a position that is inclined relative to its upright vertical position in order to modify the shape of the inside face under the effect of gravity.
Method for producing glass bottles by automatic forming and apparatus to carry out the method
A process for producing glass bottles with shoulders includes a preform preparation step and a finishing step, in which a compressed gas is blown and the preform is rotated by 180 between the preform mold and the finishing mould. Preform preparation is achieved by introducing a glass gob into the mold through an upper aperture; inserting a blowing sleeve into the glass gob, the end of the sleeve extending beyond the shoulders of the outline of the preform of the bottle, the sleeve being closed by a plunger element slidable within its interior; opening the cavity of the sleeve to disengage the plunger element; and blowing air through the sleeve, wherein the final finishing step is achieved in an open preform mold, the volume of the cavity of the finishing mold being greater than the volume of the cavity of the preform mold by 5-20%.
Neck ring holder device for machines for forming glass containers and method for manufacturing such containers
A neck ring holder device intended to be used at a mould for forming glass containers (30), wherein the neck ring (41) for realizing the mouth (32) of the container can be opened and consists of a plurality of circumferential sectors (44) that can be moved apart from a closed position of the neck ring (41), in which the circumferential sectors (44) are coplanar and form a substantially continuous annular element, up to an open position of the neck ring (41), in which the circumferential sectors (44) are rotated out of said coplanar configuration, moving away from each other, about axes directed perpendicular to the direction of the axis (45) of said annular element, is characterised in that the movement of the circumferential sectors (44) from the closed position to the open position.
METHOD OF FABRICATING A GLASS CONTAINER, AND A CORRESPONDING INSTALLATION FOR PERFORMING THE METHOD
The invention relates to a method of fabricating a glass container, the method comprising a forming step of forming molten glass in order to obtain a semi-finished container (4) comprising a shell (5) presenting inside and outside faces (7, 8), a cooling step during which said semi-finished container is in a transient state in which the glass forming said outside face is sufficiently viscous for it not to deform under the effect of gravity, while the glass forming said inside face is sufficiently fluid to allow said inside face to deform under the effect of gravity, said method including a shaping operation while the semi-finished container is in said transient state, in which operation the semi-finished container is maintained for a predetermined time in a position that is inclined relative to its upright vertical position in order to modify the shape of said inside face under the effect of gravity.
A method of fabricating glass containers, and a corresponding fabrication installation.
Neck ring system and glassware forming process
A glassware-forming neck ring system includes a neck ring assembly and a carrier assembly carrying the neck ring assembly. The neck ring assembly includes a neck ring guide having a first forming aperture therethrough around a vertical axis, and a neck ring divided along a longitudinal axis into neck ring sections carried by the neck ring guide and movable toward and away from one another along the neck ring guide along a lateral axis. The carrier assembly includes a carrier having a body with a second forming aperture therethrough, longitudinally opposite ends, laterally opposite sides between the ends, and a channel extending between the sides, restricting movement of the neck ring assembly along the vertical and longitudinal axes, and permitting movement of the neck ring assembly along the lateral axis.
Method and equipment for manufacturing a thin, hollow glass item
The invention relates to a method, comprising: feeding at least one molten-glass parison into a parison mold; forming, in the parison mold, a blank of an item from said at least one parison; transferring the blank of the item into a finishing mold; and forming the item in the finishing mold. While forming the item in the finishing mold, excess glass is directed out of the base of the item so as to form a convex bulge, and said bulge is removed such that the thickness of the base of the item is substantially constant.
Neck Ring System and Glassware Forming Process
A glassware-forming neck ring system includes a neck ring assembly and a carrier assembly carrying the neck ring assembly. The neck ring assembly includes a neck ring guide having a first forming aperture therethrough around a vertical axis, and a neck ring divided along a longitudinal axis into neck ring sections carried by the neck ring guide and movable toward and away from one another along the neck ring guide along a lateral axis. The carrier assembly includes a carrier having a body with a second forming aperture therethrough, longitudinally opposite ends, laterally opposite sides between the ends, and a channel extending between the sides, restricting movement of the neck ring assembly along the vertical and longitudinal axes, and permitting movement of the neck ring assembly along the lateral axis.
