Abstract
A lightguide starting tube or rod (12) passes through opposed lateral openings (51--51) in a chamber (31) which contains an oxy-hydrogen torch (14) used to deposit particulate glass on the rod. Frusto-conical, laminar flow, gas shields (71 and 72) are formed about the rod (12) on both sides of said openings (51--51) to permit the rod to pass therethrough in spaced relation to the openings while sealing said openings to prevent gas or undeposited particulate from passing therethrough and preventing contaminants from entering the chamber (31).
