ABSTRACT:
A distinctive method and apparatus for depositing a pattern of material, such as hot-melt adhesive, onto a substrate comprises a supplying mechanism for forming a first and at least a second substantially continuous stream of the selected material, and a gas-directing mechanism for forming a plurality of gas streams. The gas streams have selected velocities and are arranged to entrain the material streams to impart a swirling motion to each of the material streams as it moves toward the substrate. A transport mechanism moves the substrate relative to the supply mechanism along a selected machine direction. A regulating mechanism controls the supplying mechanism and gas-directing mechanism to direct the material stream in a selected path toward the substrate and deposit the material in adjacent semi-cycloidal patterns on the substrate while closely controlling a selected cross-directional positioning of one or more of the deposited patterns.
