In a glassware forming machine, an actuating assembly of an operative member has a tubular connecting body; a shaft for supporting the operative member coupled to the connecting frame to translate and rotate about a fixed axis thereof; a pneumatic jack for displacing the supporting shaft along the axis; a cam and tappet device for rotating the supporting shaft in opposite directions about the axis and having a chamber and a cam and tappet assembly housed in the chamber and lubricated by a lubricating liquid contained in the chamber; and a hydraulic device for stabilizing the motion of the shaft; the chamber and the hydraulic stabilizing device constituting part of a single closed hydraulic circuit for feeding a common lubricating and operative liquid to the cam and tappet device and to the hydraulic stabilizing device.

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.

A system for forming a glass article includes a mold assembly and a burner assembly. The mold assembly includes a mold body that defines an open cavity configured to receive a glass-containing material in a molten state. The mold assembly further includes a plunger configured to be actuated towards the mold body and into the open cavity to press the glass-containing material into a closed volume defined by the mold body and the plunger. The mold assembly further includes (i) first surfaces that define the closed volume and (ii) one or more pairs of second surfaces that make sliding contact when the plunger is actuated. The burner assembly is configured to form a solid lubricant on active surfaces of the mold assembly. The active surfaces include all the first surfaces and at least one second surface of each of the one or more pairs of second surfaces.

A robotic mold lubrication system includes a robot that is translatable along a blow side of an individual section glass container forming machine and a mold spray tool carried by the robot. The mold spray tool includes at least one set of nozzles. To lubricate one or more target blow molds of one or more of the individual sections of the forming machine, the robot is translated to the designated individual section, the mold spray tool is moved by operation of the robot to the target blow mold(s), and the target blow molds are lubricated by applying the lubricant to the target blow mold(s) from the mold spray tool. The robot may acquire the mold spray tool from, and return the mold spray tool to, a trolley that is translated along the blow side of the forming machine along with the robot.
