Abstract
A glass forming machine, a method for lubricating a baffle and a swabbing device for a glass forming machine is disclosed. The glass forming machine comprises a blank station with a blank mould for forming a parison from a gob of molten glass inside the blank mould. The glass forming machine further comprises a baffle for closing the blank mould. The glass forming machine further comprises a swabbing device which is configured to spray lubricant onto the baffle for lubricating the baffle. This enables a particularly high quality of the formed parisons and the corresponding glass containers.
Claims12
A glass forming machine comprising a blank station with a blank mould for forming a parison from a gob of molten glass inside the blank mould and a baffle for closing the blank mould, wherein the glass forming machine further comprises a swabbing device which is configured to spray lubricant onto the baffle for lubricating the baffle, wherein the swabbing device comprises a spray bracket with at least one nozzle and/or with a rod-shaped extension having a nozzle, wherein the glass forming machine is configured such that the baffle can be moved to an upper position vertically above the blank mould, wherein the swabbing device comprises, on a back face of the spray bracket, a nozzle of the at least one nozzle to spray lubricant onto the baffle when the baffle is in the upper position.
A swabbing device for a glass forming machine, the glass forming machine comprising a blank station with a blank mould for forming a parison from a gob of molten glass inside the blank mould and a baffle for closing the blank mould, wherein the swabbing device is configured to spray lubricant onto the baffle for lubricating the baffle,
- wherein the swabbing device comprises a spray bracket with at least one nozzle and/or with a rod-shaped extension having a nozzle;
- wherein the glass forming machine is configured such that the baffle can be moved to an upper position vertically above the blank mould, wherein the swabbing device comprises on a back face of the spray bracket a nozzle of the at least one nozzle to spray lubricant onto the baffle when the baffle is in the upper position, or
- wherein the glass forming machine is configured such that the baffle can be moved to a parking position beside the blank mould, wherein the swabbing device comprises on a side face of the spray bracket one nozzle of the at least one nozzle to spray lubricant onto the baffle when the baffle is in the parking position.
