ABSTRACT:
The present invention relates to the continuous production of coated, dyed, printed, or painted materials by dip coating, spraying or printing in which a plurality of flowable materials including a liquid color concentrate are fed to a continuous mixing chamber with a substantially continuous input and output. The liquid color concentrate is dispensed by a dispensing apparatus including at least a first substantially vertical hollow chamber; a controllable pump device having an inlet fluidly connected to an outlet of said first hollow chamber for pumping the liquid color concentrate to the mixing chamber; a sensor for outputting substantially continuously a signal dependent upon a height of a liquid in the first hollow chamber; and a control device suitable for controlling at least one flow rate determining characteristic of the controllable pump in response to the output signal of the sensor so as to maintain the flow rate of the liquid to be dispensed through the pump device at a predetermined value. The method and apparatus are particularly useful in the manufacture of printed carpets.
