  • Publication number: 20180163091
    Abstract: A system for dispensing hot melt adhesives, comprising an adhesive dispenser including a fluid passage leading to an outlet. The system further comprises a supply conduit fluidly connected to the fluid passage and a feeding mechanism configured to feed an elongate, flexible element of solid adhesive into the supply conduit. The system further comprises a first heating element positioned along at least a portion of the supply conduit to melt a portion of the elongate, flexible element being fed into the supply conduit and thereby form a supply of liquid adhesive within the supply conduit.

  • Publication number: 20180017200
    Abstract: A multi-layered hot melt adhesive transfer hose is provided. The transfer hose has a barrier layer that prevents or minimizes the ingress of oxygen and other gases into a conduit of the hose. The transfer hose has at least one structural layer overlaying an exterior surface of the barrier layer to help the hose withstand a high fluid pressure. The barrier layer prevents the hot melt adhesive being transported in the hose from discoloring and charring when the adhesive is heated from about 250° F. up to and including 450° F. for an extended period of time.

  • Patent number: 9731486
    Abstract: A heat exchange device for heating liquid adhesive material to an application temperature suitable for an adhesive bonding application includes a body having an inlet configured to receive a flow of liquid adhesive material and an outlet configured to provide the liquid adhesive material to a dispensing device for the adhesive bonding application. A fluid passageway in the body connects the inlet and the outlet. The fluid passageway includes a thin slit section in the form of an elongated ring shape, having a length along a fluid flow direction between the inlet and the outlet, the thin slit section further having a first dimension and a second dimension transverse to the fluid flow direction. The first dimension and the length are substantially greater than the second dimension. The heat exchange device further includes a heating element for heating the liquid adhesive material flowing through the thin slit section.

  • Publication number: 20160089681
    Abstract: A force amplifying driver system including an actuator with a powered actuating member mounted for movement along a first distance “X”. A driven member mounted for movement along a second distance or working distance “Y” which is less than the first distance “X”. The powered actuating member is movable through a gap “Z” before being mechanically coupled with the driven member and subsequently moves with the driven member along the second distance “Y”. Energy is transferred from the powered actuating member to the driven member along the second or working distance “Y”. The force amplifying driver system may be used for actuating a fluid jetting dispenser.

  • Patent number: 8753713
    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.
