Abstract
A neck ring assembly including ejector pins for engaging a parison finish for holding a parison centrally within a neck ring upon the initial opening of the assembly in a positive stripping action. After a small amount of neck ring opening, the neck rings are free of the parison finish permitting no further side load on the take-out mechanism. The stripping mechanism including ejector pins is then completely drawn away from the parison to allow the parison to be removed. The device is simple in construction, has few moving parts, and requires no auxiliary power for operation.
