ABSTRACT:
A method of and apparatus for feeding a chemical into a liquid flow are especially suited for use with a headbox of a paper machine, particularly for feeding a retention aid into a fiber suspension flow going to the headbox so that in a mixing apparatus feed liquid is added into the retention chemical solution, prior to introducing the solution into the fiber suspension flow guided to the paper machine. The feed liquid is preferably a circulation water from the paper mill, or another non-clean liquid from a paper mill.
