Abstract
A method for re-establishing or tending to re-establish symmetrical distribution of temperatures between right-hand and left-hand sides of a cross section of a flow of molten glass that has been routed in a feeder including at least one bend area, thermal asymmetry having been induced by flowing round a bend. The feeder includes a flow channel, formed from refractory and insulative material elements and including a horizontal sole plate and two lateral walls, and a vault capping the channel, formed of a refractory roof and lateral parts including burners. In an area of each bend, the flow channel is modified by choosing a corresponding inclined sole plate portion, the inclination being chosen so that the flow channel is deeper in an outside region of the bend than in its inside region, heights of the two lateral walls of the channel being modified accordingly.
