Abstract
Jetting dispensers and methods of non-contact dispensing a hot melt adhesive onto a substrate. The method may include jetting a plurality of droplets of the hot melt adhesive from a nozzle outlet toward the substrate in a direction of travel. Each droplet has a droplet length approximately aligned with the direction of travel and a droplet width shorter than the droplet length. The jetting is controlled such that each of the droplets does not collapse into a spherical-shaped droplet during flight from the nozzle outlet to the substrate. The nozzle outlet may be heated to a first temperature, and the method may further include rapidly heating each droplet of the hot melt adhesive to a second temperature higher than the first temperature upon release from the nozzle outlet.
