Glass container forming machine for blowing of a parison

摘要

An I.S. glass bottle forming machine is provided wherein a parison (10) is blown into a bottle in a blow mold (14). The parison is initially suspended from a neck ring mechanism and the blow mold halves are displaced to close around the parison below the finish (12). The neck ring mechanism is displaced away from the mold and a blow head (18) is located on top of the mold to provide final blow. A heat sensor (22) senses when the parison, during reheat, has reached the bottom (15) of the mold, and supplies a signal to a controller (30) which starts final blow based on the time when this signal was supplied.
