Patent ID: 8753713

Claim:
A method of non-contact dispensing a hot melt adhesive onto a substrate, the method comprising: jetting a plurality of minute droplets of the hot melt adhesive from a nozzle outlet toward the substrate in a direction of travel, each droplet of the hot melt adhesive being elongate and having a droplet length approximately aligned with the direction of travel and a droplet width shorter than the droplet length during flight between the nozzle outlet and the substrate, wherein the substrate includes a groove defining a groove width of 0.5 millimeters or less, each droplet of the hot melt adhesive is sized such that the droplet width would be about 1.0 millimeter if the droplet reshaped into a spherical shape, and jetting the hot melt adhesive further comprises: applying the plurality of droplets into the groove on the substrate such that none of the hot melt adhesive flows out of the groove.
