ABSTRACT:
The invention relates to a manufacturing apparatus for simultaneously making different hollow glass products having different gob sizes comprising at least one feed apparatus (12), that has at least one glass reservoir (14), at least one plunger (18a, b), and at least one appurtenant cutting device (24a, b) in the discharge from the reservoir, at least one conveying means (28) to successively transport at least one of the gobs discharged from the feed apparatus (12) into a plurality of shape-imparting units (32a–c) disposed next to each other for variously sized gobs, at least one controller (22) to control the plunger (18a, b) and the cutting device (24a, b) of the feed apparatus (12), the conveying means (28), and the shape-imparting units (32a–c), and said controller (22) controls the activity of the shape-imparting units (32a–c), the feed apparatus (12), and the conveying means (28) in coordination with the gob-size-specific processing time of the products in the shape-imparting units (32a–c) or their cycle time, and the controller (22) is embodied in such a way that, when it determines that the feed times of at least two shape-imparting units (32a–c) will coincide, or if the interval between the times that two of the shape-imparting units (32a–c) are fed will be less than the time necessary for a feed operation, the feeding of one of the shape-imparting units (32a–c) that is to be fed will be delayed and shifted to a subordinate available time window that is long enough to allow the feeding of the not-yet-fed shape-imparting unit(s) to be performed.The invention also relates to a manufacturing process for hollow glass products that uses the said apparatus. Glass products having different masses can be made simultaneously in a single manufacturing apparatus.
