A glassware forming machine system includes an individual section glassware forming machine having a plurality of sections, each with at least one blank mold (20,22,24), and a gob distributor (12) for distributing molten glass gobs to the blank molds of each machine section in sequence. The molten glass gobs are delivered to the blank molds of each section through deflectors (14, 16, 18) on which the glass gobs slide to each blank mold. At least one liquid coolant passage is integral with each deflector, and the several coolant passages for the entire machine are connected in parallel between source and return liquid coolant manifolds (36, 38). Variable flow control valves (40 or 40a) are individually connected between each liquid coolant passage and the return manifold for controlling flow of liquid coolant through the passages and thereby balance temperatures among the parallel gob deflectors. In this way, all of the gob deflectors are maintained at the same temperature, which improves uniformity of temperature and timing of gob delivery to the blank molds of the several machine sections. <IMAGE> |
