ABSTRACT:
This relates to an apparatus for blow molding from preforms hollow articles, particularly beverage bottles, at a high production rate. The apparatus incorporates a clamp assembly which receives therein carriers containing a number of preforms arranged in a line and wherein there are two mold units, one on each side of a central longitudinally elongated clamp member which is mounted for transverse reciprocatory movement. When the clamp member is positioned to close one mold unit, it operates to open the other mold unit so that while preforms in the closed mold unit are being blow molded, the other mold unit is open and may have the carrier supporting previously blow molded articles displaced therefrom and replaced by a carrier containing a new set of preforms whereby, when the blow molding operation of the one mold unit is completed, the other mold unit is ready for closing and a blow molding operation. This abstract forms no part of the specification of this application nd is not to be construed as limiting the claims of the application.
