An improved system and method for forming falling hot glass gobs which will be molded into glass containers in an Individual Section (IS) machine is disclosed which controls the weight, length, and shape of such glass gobs as they are produced. The system includes a gob feeder apparatus and a gob shearing mechanism a controller using models being used to correlate the effect of a number of feeder control settings on gob weight, length, and, shape. The controller is configured to adjust various feeder control settings based on a prioritized order of the feeder control settings such that gobs having different physical characteristics for different ones of the individual sections can be produced during a single machine cycle. By implementing the models, a closed loop system has been developed to set up controls to achieve the desired gob forming for each individual section and cavity.
