Abstract
Techniques involve cleaning a polymer melt, which allow volatile foreign substances and solid foreign substances to be removed from the polymer melt. Such techniques involve a filter element and a vacuum of a vacuum chamber. The polymer melt is fed through the filter element into the vacuum of the vacuum chamber, The filter element binds the solid foreign substances and the vacuum chamber takes up the volatile foreign substances.
