Abstract

Equipment for injecting or spraying synthetic resins by dispensing via a mixing nozzle two reagent mixtures drawn in fixed proportions at the same pressure by twin double action pumps operating on the respective reagent feed lines by the action of a common driving ram. The mixing head is connected via 3-way valves to supplies of a rinse solvent and of compressed air which can enter the head through each supply line. Esp. suitable for building up sprayed coatings by applying successive coatings. Will maintain constant proportions of prepared supply reagents in the sprayed material regardless of the rate of discharge. Readily prepared and cleaned, Negligible risk of internal backmixing of the reagents, due to ease of rinsing.
