In the manufacture of glassware gobs of molten glass are formed by gob forming apparatus. A gob is formed by the action of vertically reciprocating plungers (20, 21) forcing the glass down through orifices (6, 7) in the floor of a trough (1) below which orifices shear blades separate the gob. A bridge (10) is mounted spanning the trough on which means (25) reciprocating the plungers (20, 21) is mounted. Also mounted on the bridge (10) is a hollow metering cylinder (30) via its suspension means. The suspension means is mounted on the bridge (16) nearer to the trough (1) than the reciprocating means (25). Means for altering the vertical position of the metering cylinder (30) and for rotating it about its major axis are also mounted on the bridge (10). |
