  • Patent number: 4578099
    Abstract: Hollow glassware is made in a method wherein a necking shear is displaceable between one end position blocking one end of a passage of a preform mold and another end position at a final mold and a liquid is sprayed into the other end of the passage of the preform mold. In addition the necking shear is temporarily retained in an intermediate position between the two molds and simultaneously the liquid is sprayed into the passage. This passage is upright and the one end is below the other end. Thus a pocket of air that would prevent the mist from settling in the passage is not created, and the passage can be effectively wetted even by a relatively small volume of liquid. A bottom-blowing unit constituted as a vertically displaceable plug is provided below the preform mold. This plug is raised once the gob is in place and during top blowing to form the initial hollow in it and is shielded during spraying of the liquid into the passage.
