ABSTRACT:
In a method for automated colour mixing in a customer-operated and enclosed arrangement, a container with colour base component can be inserted and shaken, the tin with the shaken colour base component is provided with a hole, one or more doses of colour pigment are added via the hole, the hole is closed and shaking is then carried out again. Devices for carrying out the said functions are controlled by microcomputer equipment that is arranged to work interactively with the customer. The making of the hole is carried out using a knife edge or injection device that penetrates the material of the container. The dosing of the colour pigments is carried out by means of a pump and valve arrangement in which one or more valves are opened and closed or by means of a pressure or piston arrangement. The dosing is initiated in the open state of the valve or by activation of the pressure or piston device. The invention also relates to an arrangement and has the advantages provided by optimal hole-making and dosing functions.
