Abstract
A molding apparatus for the manufacture of pipe advantageously uses a cooling plug that is adjustably-secured to the extrusion head to compensate for misalignment of the extrusion head relative to recirculating mold blocks. This provides a simplified adjustment for adjusting the molding apparatus to correct for wall thickness variations in the molded pipe. This apparatus can be used in combination with existing alignment systems.
