Abstract
An apertured dead plate insert fabricated of a contact material, preferably graphite, and a correspondingly apertured dead plate subplate together constitute a dead plate assembly which is used in the hot end process area of glass bottle manufacture. The assembly can be easily repaired by replacement of the contact material insert. Use of the dead plate assembly reduces damage to hot formed glass bottles and results in increased production rates. The dead plate subplate is a rigid plate with a planar depression having an area corresponding to the area of the insert defined on one face by mounting lugs and an area of increased height on the other face corresponding to the area of the depression so as to provide a heat sink for the subplate in order to keep the insert at a relatively constant temperature variant during passage of air therethrough.
