Abstract:
1. A method of dispensing multiple adhesive filaments onto a substrate in a random pattern, comprising: moving the substrate along a machine direction; discharging multiple adhesive filaments towards the substrate, the discharged filaments being discharged along a first plane; discharging a first pair and a second pair of pressurized air streams, respectively, from opposite sides of each corresponding discharged filament, with the air streams of the first pair of pressurized air streams positioned so as to converge towards one another in a second plane generally parallel to and spaced from the first plane of the corresponding discharged filament, and the air streams of the second pair of pressurized air streams positioned so as to converge towards one another in a third plane generally parallel to and spaced from the first and second planes; contacting each of the discharged filaments with the discharged air from opposite sides of the discharged filament, causing the discharged filament to move back and forth in random directions; and, depositing the discharged filaments onto the substrate in a random pattern.
