Abstract
An annealing apparatus for a float glass continuously anneals a glass ribbon molded in a float bath. The annealing apparatus includes a lehr housing having an inlet and an outlet for the glass ribbon, a plurality of lehr rolls rotatably installed to the lehr housing in a width direction of the lehr housing, and labyrinth seals installed between the lehr rolls and sidewalls of the lehr housing, respectively, to prevent sulfurous acid gas supplied into the lehr housing from discharging out.
Claims2
