ABSTRACT:
A method and apparatus for distributing a flowable material over a base surface and wherein said flowable material is centrifuged from the peripheral region of a rotary member to produce an annular spray pattern, concentric with the rotational axis of the rotary member, and said rotary member is displaced over the base surface, characterized in that the annular spray pattern issuing from the periphery of said rotary member is interrupted at two locations, spaced apart, to obtain, at the base surface, two arcuate spray patterns, and the flowable material interrupted at said two locations is directed to a second rotary member and centrifuged from a peripheral region thereof to produce an annular spray pattern at said base surface. Preferably the two arcuate spray patterns are superimposed on the annular spray pattern to obtain a uniform distribution of material transverse to the direction of travel.
