Abstract:
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 a neck ring arm to carry said neck ring; providing an air plenum having an internal cavity defining a flow path that extends radially toward said axis and axially to an outlet; providing a plunger wear plate stationarily disposed overlying at least a portion of said air plenum, and having an axially oriented opening for receiving air directed from said air plenum; providing an air passage adjacent to said neck ring, said air passage being aligned with the outlet of the air plenum and being defined at least in part by an opening in said neck ring arm for receiving air from said axially oriented opening in said plunger wear plate across a gap between said neck ring arm and said plunger wear plate when said neck ring arm overlies said plunger wear plate; 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 passage including the neck ring arm opening to cool the neck ring and at least a portion of said neck ring arm.
