15. Abstract, Blow head supporting and moving mechanism of a glassware forming machine, A blow head which defines an upper portion of a mould cavity in which glass parisons are blown to the shape of mould cavity is moved into and out of operative position by a combination of horizontal and vertical movement. The vertical movement is brought about by a first piston and cylinder assembly (24, 26) and a second piston and cylinder assembly (38, 40) is operable, as the blow head approaches the parison, to oppose the action of the first piston and cylinder assembly (24, 26) thereby cushioning any impact between the blow head (4) and the parison.
