Blow nozzle, notably for foundry cores

摘要

The blow nozzle for use notably in foundry works in the so-called hot-box process for manufacturing sand molds and cores comprises a central barrel or tube on which a pair of tubular sleeves adapted to slide in relation to each other are fitted. These sleeves comprise diametrally opposite elongated notches and are indexed and secured to the filling tray of the hot box by means of a tip holder on which a plastic tip is resiliently fitted.
