A device for manufacturing hollow glass article consists of a plurality of modular stations that, among other things, comprise blank molds and finish molds, wherein a housing (6) is provided and can be displaced along a blank mold side (3) in order to carry out at least control and servicing functions, and wherein said housing is formed by a key-like structure that is open in the direction of the blank mold side (3) and serves as a carrier for at least one manipulation element (7) consisting of multiple sections. On its free end, this manipulation element carries a tool or a device that is ready for use after it has reached the respective station. The shielding effect of the housing (6) reliably protects an operator side against accidents due to inadvertent interventions in machine motion sequences.

In a glassware forming machine, an actuating assembly of an operative member has a connecting frame; 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 provided with a rod connected to the supporting shaft; a cam and tappet device for rotating the supporting shaft in opposite directions about the axis; and a hydraulic device for stabilizing the motion of the shaft; the rod having at least one hollow portion for housing the hydraulic motion stabilizing device.

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.
