Abstract

A mixing apparatus dispenses a composite material blended from metered components, at least one of which may be a viscous material. The apparatus includes a blending assembly for blending the components into the composite material and for thereafter dispensing the composite material out of a dispensing nozzle. The apparatus also has metering assemblies which are in communication with a respective component and which are each switchable between a measuring mode and a discharge mode. A control system concurrently places the metering assemblies in the discharge mode, and an ejection assembly concurrently ejects the selected quantities of the components into the blending assembly and thereafter out of the dispensing nozzle. The blending assembly is disclosed to be a static or a dynamic, and, where a static system is used, a plurality of static elements are disposed in a serpentive flowpath. The metering assemblies may include metering cylinders that are mechanically linked or otherwise controlled to measure and dispense the components, and structure is provided to allow variation in the ratios and quantities of the components.
