Neck ring cooling
First Claim
1. A method of cooling a neck ring in a glassware forming machine including a section box providing a supply of cooling air, and a plunger cylinder having an axis, including the steps of:
- providing an air plenum having an internal cavity defining a flow path that extends radially toward said axis and axially to an outlet;
providing an air passage adjacent to said neck ring, said air passage being aligned with the outlet of the air plenum; and
directing cooling air from said section box to said air passage so said cooling air flows radially in said air plenum toward said axis, and then axially from said outlet to said air passages to cool the neck ring.

Abstract
A system for directing cooling air onto a neck ring in a glassware molding machine that includes at least one air plenum stationarily disposed at a blank mold station and having an internal cavity for receiving cooling air flowing laterally inwardly toward the axis and at least one outlet opening adjacent to the axis, a plunger wear plate disposed overlying at least a portion of the air plenum, and having an array of axially oriented openings for receiving air directed from the air plenum, a plurality of openings in the neck ring arm for receiving air from the openings in the plunger wear plate across a gap between the neck ring arm and the plunger wear plate when the neck ring arm overlies the plunger wear plate, and a plurality of air passages in the neck ring for receiving air from the neck ring arm openings.
