A distribution head having an inlet for accepting a stream of fluid plastic and an outlet for discharging the stream, two pairs of discrete channels in the distribution head extending from the input to the output for splitting the streams into corresponding discrete substreams, selected ones of the channels being of predetermined different lengths to provide lateral mixing of the stream as it passes through the head. The invention also includes a combination of the distribution head and a connected extrusion tool and the process of making homogeneous plastic articles, particularly pipes. |
