Publication number: 20230348308Abstract: A glass forming machine and a method for manufacturing formed glass parisons. A glass forming machine includes a blank side for forming parisons from gobs of molten glass. The blank side includes a plunger and a blank mould. The plunger can be moved into the blank mould up to an end position. The plunger can be moved out of the blank mould up to a start position. The glass forming machine includes a glass feeding device which is configured to bring a gob of molten glass into the blank mould. The glass forming machine includes a measuring device which is configured to measure the end position of the plunger. The glass feeding device is configured such that the size of a gob of molten glass depends on the end position previously reached during operation. Parisons of good quality can be produced with a bigger tolerance of mould volumina.Type: ApplicationFiled: July 6, 2023Publication date: November 2, 2023Inventors: Andreas Walter Helfenstein, Leo Diehm

Patent number: 11629086Abstract: 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.Type: GrantFiled: April 6, 2020Date of Patent: April 18, 2023Inventors: Thomas Alexander Bewer, Leo Diehm, Inge Ulf Friberg, Martin Gronblad

Patent number: 9212083Abstract: A system and method for coating glass gobs with a liquid-based lubricating dispersion during their drop to blank glass container molds which provides sufficient lubrication to the glass container molds without requiring swabbing of the glass container molds. The lubricating dispersion is sprayed onto hot glass gobs as they fall from the gob supply system prior to their distribution by the gob distribution system into blank molds. The lubricating dispersion coats the falling glass gobs to lubricate the glass gobs as well as the molds.Type: GrantFiled: February 19, 2014Date of Patent: December 15, 2015Assignees: Emhart Glass S.A., Imerys Graphite & Carbon Switzerland SAInventors: Leo Diehm, Thomas L.

Patent number: 6857291Abstract: A blow mold assembly for an I.S. machine for blowing a parison of glass and cooling the blown parison into a formed bottle which can be removed from the blow mold. A blow head is lowered onto a blow mold and final air is applied. A predetermined time after the blow head engages the top surface of the blow mold the blow head is lifted a selected vertical distance above the top surface of the blow mold to an exhaust position allowing cooling air to escape from the blow mold. The selected vertical distance is selected so that at least a minimum pressure will continue within the formed bottle. The blow head is maintain at the exhaust position for a predetermined time and then retracted. The selected vertical distance and the predetermined time can be set as desired.Type: GrantFiled: December 5, 2001Date of Patent: February 22, 2005Assignee: Emhart Glass S.A.Inventors: Leo Diehm, F.

Patent number: 6807829Abstract: A blow head is displaced to the “on” position where its lower portion engages the top of a blow mold. Final blow begins and before final blow is completed, the blow head is raised a selected distance and final blow is exhausted between the O.D. of the formed finish and the upwardly defined annular recess in the lower portion of the blow head. The annular recess is concavely curved to direct exhaust air at the finish to cool the finish.Type: GrantFiled: December 5, 2001Date of Patent: October 26, 2004Assignee: Emhart Glass S.A.Inventors: F.

Patent number: 6050172Abstract: A pneumatically operated mechanism for a glass machine comprises a piston and cylinder device, first and second air lines leading to opposite sides of the piston, and first and second control means for controlling the passage of air through the air lines, which control means each comprise an operating valve and a speed control valve. The valves are solenoid operated and by control of the timing of operation of the valves the speed of movement of the piston and the degree of cushioning at the ends of its stroke may be adjusted. In a modified mechanism pressure sensors which sense the pressures in the piston and cylinder device are connected to a processor which is adapted in response to data sensed by the sensors to operate the valves to obtain a desired movement of the piston.Type: GrantFiled: March 17, 1998Date of Patent: April 18, 2000Assignee: Emhart Glass S.A.Inventors: Burkhard Corves, Rudolf Schwegler, Leo Diehm
