ABSTRACT OF THE DISCLOSURE When multiple gob feeders are used in which an enlarged tube is necessary to accommodate a row of plungers, a substantial surface area of glass is exposed to radiation or convection cooling and, to avoid excessive heat loss, a pair of heat baffles are used which extend downward into the tube at either side of the row of plungers. The baffles have lower portions which occupy a significant part of the space between the plungers and tube, and act as barriers against the movement of heat up through the space therebetween. The pair of baffles are so configured that they may be raised from the tube without requiring the removal of the plungers. Further, the baffles are supported in the tube by the tube support and therefore will be raised or lowered with the tube when it is adjusted.
