Abstract: The sleeve-type glass melt agitator has a rotatable cylindrical sleeve provided with outwardly protruding vane elements and through-going openings in its outer cylindrical surface to stir the glass melt when the sleeve is rotated. The sleeve type agitator is arranged vertically in a glass melt feed channel in a glass melt feed system for making glass tubes or pipes according to the Vello or down-drawn process. During formation of glass tubes or pipes from the glass melt the sleeve-type agitator is rotated as the glass melt flows downward to prevent formation of schlieren in the glass melt, which causes glass material losses.
