A reheat blow mold machine includes a preform loader, an oven, a mold station and a preform transfer mechanism for transporting preforms form the oven to the mold station. A loader defines a plurality of lanes within which the preforms are supported. A reciprocal jaw assembly moves the preforms from a receiving end to a load end of the oven. The oven includes a plurality of tandemly arranged abutting pallets which rotatably support the preforms. The pallets are stepped through the oven and moved between a receiving end and a discharge end by a pair of elevators and a return conveyor. The transfer mechanism includes two sets of jaw assemblies, a pair of slidable actuators and a compensation mechanism to automatically adjust for tolerance variations in the diameter of the performs. A mold station includes a pair of opposed platens which support mold halves. A bottom platen is positioned by a cam arrangement mounted on the opposed platens.

A machine for high rate production of molecularly oriented thermoplastic bottles is disclosed. The machine is of the reheat-and-blow type. A blow molding station simultaneously blow molds article preforms arranged in matrices by modular article carriers for conveying the preforms and articles through the machine. The carriers are designed to retain the preforms throughout all operations of the machine from a preform load station through a thermal conditioning section, a blow molding station, and to a bottle eject station, thereby eliminating the need for other preform transferring apparatus. The article carriers together with the associated conveying apparatus comprise a sufficiently flexible structure that minor misalignments of the carriers with the blow molding mechanism do not adversely affect bottle production. Both loading of preforms and ejection of finished bottles are accomplished by operation upon matrices of preforms and bottles as defined by the carriers and conveyor lanes.

An injection molding machine base has a generally rectangular form having as an integral part thereof a hydraulic return line formed within the base. The return line is straight, has clean-out openings at each end, and no obstructions therein whereby removal of closures at each end exposes the entire cross-section for cleaning. Hydraulic equipment on the machine exhausts directly into this maze. One end of the base has a connection to the hydraulic reservoir for the machine.

A coupling includes a pair of cup-shaped members with one mounted for sliding axial motion inside the other. The outside coupling acts as a support or base which is connected to a conveyor that moves the coupling between workpiece loading and unloading means. The inside member also carries detents which move radially in and out to grasp or release the workpiece in response to axial motion between the two cup-shaped members. When combined with a conveyor, appropriate cam and follower means are provided to cause the coupling to be operated for grasping and releasing the workpiece in a timed sequence and to move the coupling from a workpiece loading station to an unloading station. The coupling and conveyor are suited for use in handling soft or easily marked materials such as plastic, soft metals, and the like. A method for workpiece handling includes steps of rotating, advancing in stop-and-go fashion while continuously rotating, and unloading.
