Work tables in apparatus for blowing hollow glass articles |
摘要 |
A work table in a glass forming unit in apparatus for producing hollow glass articles has an orifice plate which is loosely fitted in a recess of the work table. Therefore, the orifice plate can be removed or mounted on the work table instantly while the orifice plate is firmly secured to the work table during the operation of the work table because the orifice plate expands by the heat of the handled molten glass to be friction-fitted in the recess. The orifice plate is formed of material having a coefficient of thermal expansion equal to, or relatively larger than, that of the work table.
