Abstract
A glass container production line and process include a first step of heating a portion of the glass container by delivering microwaves and conveying them to the portion of the glass container. Microwave delivery is carried out at a first power level for a first time interval so as to bring the portion of the glass container from an ambient temperature to an intermediate temperature, and at a further power level, which is lower than the first power level, for a further time interval following the first time interval, so as to bring the portion of the glass container from the intermediate temperature to a first predetermined working temperature.
Claims17
A glass container production line comprising:
- N workstations configured to perform respective production steps on glass containers being processed along the line, wherein N is an integer at least equal to 1;
- M heating devices associated with at least a part of the N workstations to heat portions of the glass containers being processed, wherein M is an integer at least equal to 1;
- wherein the M heating devices respectively comprise M microwave sources and M adjustment units operatively associated with the M microwave sources, each of the M adjustment units being configured to adjust in power the respective microwave source;
- wherein one or more workstations of the N workstations is intended to perform a first heating step to bring a portion of each glass container being processed from an ambient temperature to a predetermined first working temperature, the adjustment units of the heating devices of said one or more workstations being configured to adjust the respective microwave sources so as to deliver microwaves while performing the first heating step:
- at a first power level P1 for a first time interval T1 so as to bring said portion of said glass container from the ambient temperature to an intermediate temperature, and
- at a further power level P3, which is lower than the first power level P1, for a further time interval T3 following the first time interval T1, so as to bring said portion of said glass container from said intermediate temperature to the first predetermined working temperature.
A glass container production process comprising a plurality of production steps, said plurality of production steps comprising a first heating step of a portion of said glass container by delivering microwaves and conveying them to the portion of said glass container, wherein the microwave delivery is carried out:
- at a first power level P1 for a first time interval T1 so as to bring said portion of said glass container from an ambient temperature to an intermediate temperature, and
- at a further power level P3, which is lower than the first power level P1, for a further time interval T3 following the first time interval T1, so as to bring said portion of said glass container from said intermediate temperature to a first predetermined working temperature.
