A method and apparatus for forming a hollow glass article comprises delivering a gob of glass to a blank mold (30), providing a first neck ring (A) to a position adjacent the blank mold (30), forming the gob in the blank mold into a parison (P), moving the first neck ring (A) to transfer the parison to a blow mold (31), blowing the parison (P) in the blow mold to a hollow article, releasing the engagement of the first ring (A) with the hollow article, moving the first neck ring (A) away from the blow mold (31), removing the hollow article from the blow mold (31), returning the first neck ring (A) to a position adjacent the blank mold (30) to repeat the cycle, providing a second neck ring (B) adjacent the blank mold (30) while the first ring (A) is moving toward the blow mold (31), delivering a second gob of glass to the blank mold (30) while the second ring (B) is in position adjacent the blank mold, forming the second gob into a second parison, moving the second parison to a position adjacent the blow mold (31) while the first neck ring (A) is being returned to a position adjacent said blank mold (30); and controlling the positioning and movement of the first neck ring (A) and second ring (B) independently of one another such that the velocity and movement of each neck ring is varied without affecting the overall forming cycle. <IMAGE> |
