A method for the production of formed products from a highly-condensed polyester melt, in which the melt never solidifies between the polycondensation reactor and the forming unit and there is no degassing device between the final reactor and the forming unit. Independent claims are also included for (1) apparatus for the process as defined above, in which there are at least two additive feed units in the melt line between the polycondensation reactor and the forming unit (2) apparatus for the process as defined above, in which the pipeline between the last additive feed unit and the forming machine contains a rotating pipe joint enabling horizontal movement of the forming machine. |
