Abstract
An extrusion head assembly for adjustably positioning a view stripe in a tubular parison to correct the view stripe positioning in situations where twisting of the parison prior to molding occurs. The apparatus includes an externally adjustable member which circumferentially positions the view stripe in the parison relative to the extrusion head assembly so that the view stripe will correspond with the mold parting line of a container blow molded from the parison. The adjustable member circumferentially positions the view stripe without causing the development of stagnation pockets in the stream of the plastic forming the view stripe. Degregation is prevented by dividing the flow of the plastic forming the view stripe into two streams which individually and continuously flow from a common inlet port to a common exit port.
