Abstract
An I.S. machine wherein a parison is blown into a bottle in a blow mold. The parison is initially suspended from the neck ring mechanism and the blow molds are displaced to close around the parison below the finish. The neck ring mechanism is displaced away from the mold and a blow head is located on top of the mold to provide final blow. A heat sensor senses when the parison, during reheat has reached the bottom of the mold and supplies a signal to a controller which starts final blow based on the time when this signal was supplied.
Claims5
An I.S. machine including a blow station for forming a bottle from a parison having a formed finish portion comprising
- a blow station including a blow mold having side and bottom portions for supporting a parison,
- a source of forming air,
- valve means for selectively connecting the source of forming air to the blow mold to form the parison into a bottle,
- heat sensor means for generating a parison at bottom of mold signal, and
- control means for operating said valve means to connect the source of forming air to the blow mold based on the time when the parison at bottom of mold signal occurs.
