摘要： A feeder trough for transferring molten glass from a glass furnace to an object-forming station, the feeder trough comprising a channel at one of its ends to the furnace and at its other end to a bowl having at least one feeder orifice a sill which has, on its downstream face, a substantially vertical wall, occupies the entire width of the channel and has a thickness of approximately 4 to 10 cm and a height such that it allows a stream of glass approximately 8 to 10 cm thick to pass over it; and a heatable bottom drain provided upstream of the sill and practically adjoining the latter.
