Abstract
An apparatus for applying a metal-oxide coating to hot, freshly formed glass containers. The apparatus includes a tunnel including spaced apart sidewalls, a conveyor for conveying hot, freshly formed glass containers through said tunnel, and a vapor distributor. The vapor distributor includes a series of alternating vapor inlets and vapor outlets arranged along each side wall of the tunnel. Each vapor inlet along one side wall of the tunnel is positioned opposite to a vapor outlet on the other side of the tunnel. Moreover, each vapor inlet and vapor outlet has a pivoted baffle positioned internally thereof, the pivoting of the baffle being effective to vary the vertical extent of an opening of the inlet and the outlet, and each vapor outlet having an adjustable flow divider internally thereof for dividing the vapor flowing into the vapor outlet into a first portion to be exhausted from the tunnel and a second portion to be recirculated through the vapor inlet into the tunnel.
