Method for thoroughly mixing a melt flow made of plastic

Image Number 4 for United States Patent #6579001.

In order to enable the thorough mixture of a melt flow S made of plastic, and polyvinyl chloride in particular, with the lowest possible amount of damage and the adequate homogenization thereof, the melt flow S is divided into partial flows T, which partial flows T are twisted independently from one another about axes extending in the direction of flow and are thereafter joined again into a common melt flow S.
