Abstract

An apparatus for pressing glass preforms and placing the glass preforms into a blowing machine is provided. The apparatus includes a first plunger configured to be reciprocated between a gob-receiving region and a first preform-pressing region, a second plunger configured to be reciprocated between the gob-receiving region and a second preform-pressing region, a first press mold associated with the first plunger and configured to be reciprocated between the first preform-pressing region and a preform-placing region, and a second press mold associated with the second plunger and configured to be reciprocated between the second preform-pressing region and the preform-placing region. The respective plungers are configured interact with the respective associated press molds in the respective preform-pressing regions such that a gob received in the gob-receiving region by one of the respective plungers is formed into a glass preform and received by the respective associated press mold.

Dependent claims

An apparatus for pressing glass preforms and placing the glass preforms into a blowing machine, the apparatus comprising:

a first plunger configured to be reciprocated between a gob-receiving region and a first preform-pressing region;
a second plunger configured to be reciprocated between the gob-receiving region and a second preform-pressing region;
a first press mold associated with the first plunger and configured to be reciprocated between the first preform-pressing region and a preform-placing region;
and
a second press mold associated with the second plunger and configured to be reciprocated between the second preform-pressing region and the preform-placing region;
wherein the respective plungers are configured to interact with the respective associated press molds in the respective preform-pressing regions such that a gob received in the gob-receiving region by one of the respective plungers is formed into a glass preform and received by the respective associated press mold;
and
wherein the apparatus is configured such that after interaction of the respective plunger with the respective associated press mold, the respective plunger is configured to move back to the gob-receiving region while the respective press mold is configured to move to the preform-placing region to place the glass preform into the blowing machine at the preform-placing region.

5 more elements

A method for pressing glass preforms and placing the glass preforms into a blowing machine, the method comprising:

receiving a first gob by means of a first plunger in a gob-receiving region;
transporting the first gob to a first preform-pressing region by means of the first plunger;
forming a first glass perform in the first preform-pressing region by interaction of the first plunger with a first press mold, wherein the first glass preform is received by the first press mold;
moving back the first plunger from the first preform-pressing region to the gob-receiving region after the first glass preform has been received by the first press mold;
transporting the first glass preform by means of the first press mold from the first preform-pressing region to a preform-placing region and placing the first glass preform into the blowing machine;
receiving a second gob by means of a second plunger in the gob-receiving region;
transporting the second gob to a second preform-pressing region by means of the second plunger;
forming a second glass preform in the second preform-pressing region by interaction of the second plunger with a second press mold, wherein the second glass preform is received by the second press mold;
moving back the second plunger from the second preform-pressing region to the gob-receiving region after the second glass preform has been received by the second press mold;
and
transporting the second glass preform by means of the second press mold from the second preform-pressing region to a preform-placing region and placing the second glass preform into the blowing machine.
