METHODS AND APPARATUSES FOR REDUCING HEAT LOSS FROM EDGE DIRECTORS

摘要

An apparatus and method for manufacturing a glass ribbon includes a forming wedge having a pair of inclined forming surfaces that converge along a downstream direction to form a route. The apparatus further includes an edge director intersecting at least one of the pair of downwardly slanted forming surface portions, and a replaceable heating cartridge configured to induce edge director heat and thermally shield the edge director from heat loss. A replaceable heating cartridge is also provided for inducing heat to the edge director and thermally shielding the edge director from heat loss.
