Abstract
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.
