Abstract

A method sets machine parameters of a foam production machine. The foam production machine includes an intermediate conveyance unit configured to receive a reactive mixture, a plurality of fall plates having vertically adjustable ends and configured to receive the reactive mixture from the intermediate conveyance unit, and a conveyor configured to receive the reactive mixture from the fall plates. The method includes executing software by a computer system, where executing the software includes importing characteristics of the foam production machine and a rise profile for the reactive mixture, and iteratively determining process and machine parameters, including reactive mixture flow rate, conveyor speed, a dimension of the intermediate conveyance unit, and vertical positions for the ends of each fall plate resulting in a predefined predicted profile of the reactive mixture on the plurality of fall plates.
