  • Glassware making machine
    Patent number: 5122179
    Abstract: An H-28 machine is a glassware making machine having a plurality of glass making sections which rotate about a vertical axle. The complete process takes one revolution. Individual section mechanisms are controlled by electronically setable cams on a central timing drum and whenever two mechanisms sequentially occupy the same space in a section, machine speed is determined and the cam settings are checked to make certain that the mechanisms will not interfere.
