Apparatus for sprayed adhesive diaper construction

An apparatus for depositing a pattern of material onto a substrate, comprising:

• a. a first nozzle bank and at least a second nozzle bank with the first nozzle bank offset a selected distance from said second nozzle bank along a substrate movement direction of the apparatus, wherein each nozzle bank includes a plurality of spaced-apart nozzles which are substantially aligned along a cross-direction of the apparatus, and wherein the nozzles of said first nozzle bank are positioned in a staggered arrangement relative to the nozzle of said second nozzle bank,
• each nozzle including an orifice for forming a stream of said material, and including a group of gas jets for forming a group of gas streams which have selected velocities and are arranged to entrain the stream of material from said orifice to impart a swirling motion to the material stream as it moves toward said substrate;
• b. transport means for moving said substrate past said nozzle banks along said substrate movement direction;
• and
• c. regulating means for controlling the velocities of said groups of gas streams to direct each stream of material in a substantially helical path toward said substrate and deposit said material thereon to form a plurality of juxtaposed, semi-cycloidal patterns of said material on said substrate.
