ABSTRACT:
A method and apparatus is disclosed to produce a blown glass envelope on a ribbon machine having a self supporting closed end, said article being of a unitary, integral construction with glass wall thickness substantially less than that found in conventional pressed glass envelope. Said ribbon formed glass envelope has a cylindrical neck portion terminating at one end in a bulb portion of larger cross sectional dimensions and which includes the self supporting base end. The sides of said glass envelope can be curved or flat and with said self supporting base also being of a curved or planar contour. A novel mold construction permitting said glass envelope to be blown on a ribbon machine comprises a pair of cooperative halves forming the sides of the blown glass envelope in a central cavity in which further includes a separate base part located at the lower end of the said cavity to shape the self supporting base, said base part of the mold being provided with reciprocal motion in a vertical direction.
