The pressing mould is mounted onto the telescope unit, which moves the pressing mould into different positions. In the feeding station the pressing mould is supplied with a precisely defined quantity of glass by the feeder. The telescope unit then moves the mould into the pressing station. If necessary, the shearmark may be re-heated by infrared burners, before the glass item is pressed. The pressing plunger and ring are moved by the servo-motor pressing unit, which is mounted onto the crossbeam. The pressing unit is equipped with a sensor, which reduces the pressing pressure to a holding pressure as soon as the item is sufficiently pressed. All production steps, including the cooling time, are individually adjusted to the requirements of the article, since the production cycle is freely programmed. The glass item is taken out by hand or fully automatically.
