Abstract
A method for isolating a continuous strip of glass from damaging exterior influences after it has been stretched from a molten glass bath within a shell, whereby said strip, when exposed outside of said shell, is partially cooled by low of its annealing temperature and while the strip is still cooled as it passes through a stretch machine, which comprises passing the continuous strip of glass, partially cooled and uncovered, through a zone bounded by spaced barriers formed by layers of fluid which comprise currents that move in spaced planes, substantially parallel to the plane defined by the movement of the glass strip.
