Abstract
In an apparatus for laying down a blanket of foam on a waste disposal landfill or the like, an enlongate manifold carried across the rear end of a vehicle delivers foam to nozzle assemblies which are spaced apart along the length of the manifold. Each nozzle assembly includes a holder in the form of a block with a first bore communicating with the manifold and bifurcating into second and third bores which communicate with nozzles having fan-shaped flat spray patterns. The axes of the bores generally define an inverted Y-configuration with the nozzle of the second bore arranged to spray the foam downwardly to one side and within a plane angled forwardly from a transverse vertical plane with respect to the direction of forward movement of the vehicle, and with the nozzle of the third bore arranged to spray the foam downwardly to the opposite side and within a plane angled rearwardly from the transverse vertical plane.
