Abstract
An accumulator head for blow molding machines having a diverter sleeve that cooperates with other components in the head to form annular concentric flow paths for plastic material between the inlet and outlet of the diverter sleeve to divide the plastic material into two arcuate paths which subsequently meet and split into two more arcuate paths in which plastic material flows in a reverse direction relative to the first two paths and is directed to the diverter outlet. The diverter sleeve thus insures intimate mixing of the plastic material and eliminates the likelihood of a weld line in the plastic material. In addition, the diverter sleeve is mounted for up and down movement with respect to the inlet for plastic material to thereby eliminate dead points in the plastic flow path and facilitate changeover from one material to another in the head.
