Abstract
A furnace (2) has at least one furnace chamber (20) delimited by a wall (25); at least one opening (5) is provided in the wall (25). The opening is provided with at least one nozzle (50), configured to generate a sealing air flow. A glass semi-finished product (4) can be introduced into the furnace chamber.
Claims24
Device (1) comprising:
- a furnace (2) having at least one furnace chamber (20) adapted to receive a semi-finished glass product (4),
- a wall (25) delimiting the at least one furnace chamber (20), the wall having at least one opening (5) formed in a material-free manner in the form of a simple hole, the at least opening provided with at least one nozzle (50) adapted to generate a sealing air flow to reduce heat losses of the furnace chamber (20) through the hole;
- and
- a radiation source or radiation detector positioned outside the at least one furnace chamber and configured to supply or receive electromagnetic radiation through the at least one opening;
- wherein:
- the radiation source comprises at least one laser (3) configured to generate a laser beam (30);
- and
- the device is configured to direct the laser beam onto one or more predetermined partial areas (40) of the semi-finished glass product (4).

A furnace (2) configured to accommodate a semi-finished glass product (4), the furnace comprising:
- at least one furnace chamber (20) delimited by a wall (25);
- at least one opening (5) formed in a ceiling of the at least one furnace chamber (20);
- at least one laser (3) configured to generate a laser beam (30);
- at least one movable mirror (35) configured to direct the laser beam onto one or more predetermined partial areas (40) of the semi-finished glass product (4);
- a ring nozzle positioned at the at least one opening and configured to create a sealing air flow to promote heat retention in the at least one furnace chamber;
- and
- a transport pallet (7) having three contact points (71, 72, 73) which define a triangle and are configured to be received in an interlocking fashion in associated receiving devices (8) of the at least one furnace chamber (20).
