a method and apparatus for rotating a cross - sectional asymmetrical condition of a laminar flowing material is provided in a hot runner system for supplying a laminar flowing material . the hot runner system has an upstream melt passage , a pair of intermediary melt passages downstream from the upstream melt passage , and for at least one intermediary melt passage , an associated pair of downstream melt passages downstream from the at least one intermediary melt passage . the cross - sectional asymmetrical condition of a laminar flowing material is rotated by providing a bending path for orienting at least one path outlet relative to a path inlet to rotate the cross - sectional asymmetrical condition of the laminar flowing material such that the cross - sectional asymmetrical condition is substantially equally divided between the two downstream portions .
