Abstract (en)
[origin: WO2022096061A1] The invention relates to a glass extrusion assembly comprising a peripheral mirror system (3), a switchable heatable nozzle (4) having an outlet opening (41), and a transport system (2). The nozzle (4) is situated in a process chamber surrounding a heatable platform (42). The nozzle (4) and the platform (42) can be positioned in three axes relative to one another by a movement unit. The peripheral mirror system (3) is situated outside the process chamber (5). For extrusion, the glass fibre (7, 8) to be extruded can be continuously introduced from a material feed unit (1) into the nozzle (4) by means of the transport system (2), through the peripheral mirror system (3), via an inlet opening (51) of the process chamber (5). For the purpose of heating, the nozzle (4) can be irradiated using at least one controlled laser (63), wherein, in the operating state, a thermocouple monitors the heating temperature during the heating of the nozzle (4), such that the glass fibre heated by the laser light is above its melting point in the form of a flowable fluid in the nozzle (4) and can flow out of the outlet opening (41) towards the platform (42). The sub-systems can be controlled/operated simultaneously and precisely by an open-loop and closed-loop control unit and by this glass extrusion assembly being operated as intended.
