ABSTRACT:
Glass articles are made by continuously emitting a plurality of strands of molten glass spaced different distances from respective preform molds, cutting through each of the strands by moving together a respective pair of blades to form a respective gob, and transporting the gobs through the respective distances to the preform molds. The pairs of blades are operated, that is moved from an open to a closed position, such that they cut through the respective strands one after the other with the first formed gob traveling through the longest distance to the respective preform mold and the last formed gob traveling through the shortest distance to the respective preform mold.
