ABSTRACT:
A set-up fixture (50) for positioning the needle holders (18, 20, 22) of a molten glass feeder bowl with respect to one another, the fixture having a frame member (52) and a plurality of prongs (54, 56, 58) depending from the fixture, one prong for each of the needle holders of the feeder bowl installation. The prongs are inserted into apertures (24b, 26b, 28b) of base members (24, 26, 28) from which the needle holders are carried to accurately position support arms (30, 32, 34) to which the base members are affixed, and thus the needle holders and the plunger needles (12, 14, 16) carried thereby, with respect to one another. The prongs depend different distances from the frame member to permit sequential insertion of the prongs into the base member apertures.
