ABSTRACT:
An apparatus for adding a coloring agent to a material used to manufacture brick includes an extrusion container having an opening defined in the sidewall thereof. A coloring agent supply communicates with the opening for delivery of the coloring agent to the interior of the container as brick making material passes through the container. A storage device stores the coloring agent supply amount data corresponding to a supply amount for each of a plurality of brick types, each of the plurality of brick types having a different appearance. A controller is adapted to control a supply of a coloring agent from said coloring agent supply into said extrusion container in accordance with a selected brick type. A computer can be connected to the controller for data transfer. Accordingly, the computer can be used as an interface between a user and the apparatus.
