ABSTRACT:
Each glass gob is severed by a shear blade pair (6; 9). The shear blades (7, 8; 10, 11) are arranged on shear arms (12, 13) whose movement is synchronized with each other by means of a gear mechanism (16) A first shear arm (12) is drivable pivotably by a drive means (36), while a second shear arm (13) is supported by an air spring (28). The drive means (36) is carried on a carriage (39) which is displaceable by piston-cylinder units (48, 49). The drive means (36) drives a crank pin (43) which is connected by means of a coupling rod (44) with the first shear arm (12). By displacement of the carriage (39) one achieves a servicing stroke (34) which is greater than the working stroke (32) of the shears.
