Device for controlling the heating and cooling of channels, feeders and feeder spouts conducting molten glass

The invention relates to a device for controlling the heating and cooling of glass, previously made flowable in a melting furnace, in channels, feeders or feeder spouts, the glass material being fed to automatically operating machinery, for example for producing glass articles. The invention starts from a device in which the channels or feeders conducting molten glass are formed from metal pipes, preferably platinum/rhodium pipes, which in turn are used as a current-fed element. According to the invention, a plurality of feed flanges are allocated to the metal pipe and engage in a circumferentially distributed manner on the contact ring of the pipe. The current feed flanges are in this case arranged so as to be displaceable with respect to the contact ring.
