METHOD AND APPARATUS FOR MAKING WIDE MOUTH HOLLOW GLASS ARTICLES

摘要

A method and apparatus for forming a hollow article operates in a cycle utilizing two independently operated neck rings, with a conventional take out mechanism. Since the rings have individual operating mechanisms, they can start and stop independently and move at different velocities. This allows more flexibility in the process, since the reheat and run time can be varied without affecting the machine speed. After the blank and plunger are clear, the first ring transfers the parison to the blow mold. When the blow head retracts, the second ring releases the container and the mold opens. The second ring moves to the pressing station and the take out removes the formed container from the mold. The mold cannot close until the bottle clears and the first ring arrives with the parison, and the blank mold cannot move up until the second ring is in pressing position.
