Abstract

The suction feeder for glass processing includes a housing containing a material; a heatable noble metal or noble metal alloy feed line embedded in the housing in a thermally insulated fashion; a connection element at one end of the feed line for connection with a molten glass supply device and an outlet element for operative engagement with a suction device at the other end of the feed line. To prevent aspiration of bubbles through the feed line the material together with the housing surrounds the heatable feed line and has a composition and/or structure such that in operation a negative pressure can be produced on an outer side of the feed line. Preferably this negative pressure is lower than a minimum internal pressure within the feed line that is established during a suction process.
