The apparatus includes a main conduit having one end connected to the source of compressed air, and having an opposite discharge end; a tubular wall having open ends and adapted to contain a quantity of material therewithin; and a piston slidably mounted within the tubular wall. A supply conduit communicates one end of the tubular wall with the main conduit. A pressurizing conduit is arranged to cause pneumatic pressure to be selectively applied to the piston to extrude material through the supply conduit into the main conduit. Such extruded material is propelled along the main conduit by a continuous flow of compressed air therethrough, and is ultimately discharged on to the object. | |
