ABSTRACT:
A brick-forming vacuum press is provided with a die and top and bottom plungers which are disposed along the same vertical central axis as the die. Spaces which extend from the die and surround the top and bottom plungers are enclosed by chambers formed of sealing cylinders, flexible bowl-like skirts and sealing flanges. A horizontal table is provdided on the die to support a mix-filling charger and a compact-discharging pickup device. A wiper is carried by the pickup device to clean the table when the pickup device is shifted away from the vertical central axis of the press. Controls are provided to automate the filling of the die, press-forming and discharging of the resultant compact.
