ABSTRACT:
A stream of homogenized plastics material is divided into stream parts 10, 11 and 12 and additive introduced to the external surface of at least one stream part 10, 12 either at or before a gear pump 1. Subsequent passage through the pump 1 mixes the additive in before the stream parts 10, 11 and 12 are recombined downstream of the pump. Stream parts 10, 11 and 12 may be separated by partition on approach to the pump gear and also by partitions 8 and 9 in the pump 1 itself.
