ABSTRACT:
In an apparatus for conditioning a supply of molten thermoplastic material, preferably glass, a chamber in flow communication with the supply of glass is mounted for rotation about an axis. The chamber has a flow control surface having at least two regions, each uniquely oriented for influencing the flow of the molten glass therealong. In one region the glass experiences delayed flow to enable it to give up heat and in a region downstream of the first, the glass experiences accelerated flow to enable it to counteract changes in viscosity resulting from previous heat loss. The chamber is rotated so that a fresh supply of glass at an elevated temperature is deposited circumferentially on the flow control surface in order to moderate the influence of heat loss as the glass flows through the chamber.
