摘要： 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.

摘要： A hot melt adhesive system includes an adhesive supply and an adhesive supply heater associated with the adhesive supply for melting hot melt adhesive material into a liquid hot melt adhesive. An adhesive dispenser is fluidly coupled with the adhesive supply and includes an outlet for dispensing the liquid hot melt adhesive. A fluid passage extends from the adhesive supply to the outlet of the adhesive dispenser; and an adhesive degradation detection device is operatively coupled to the fluid passage. The adhesive degradation detection device includes an energy source for emitting energy into the liquid hot melt adhesive in the fluid passage. The adhesive degradation detection device further includes a detector configured for detecting attenuated energy that emerges from the liquid hot melt adhesive. A controller operatively coupled to the adhesive degradation detection device can determine a degradation condition of the liquid hot melt adhesive.

摘要： A dispensing system for dispensing a hot melt adhesive foam onto a substrate is described. The dispensing system comprises a pump having a first input to receive a hot melt adhesive and a second input to receive a gas, where the pump mixes the hot melt adhesive and the gas to produce a solution. The dispensing system also includes a temperature sensor to detect a temperature of the solution, a dispenser to receive the solution from the pump and dispense the solution, and a controller. The controller instructs the pump to operate at a first speed, receives the temperature of the solution, and instructs the pump to operate at a second speed that is different than the first speed in response to the signal.

摘要： 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.
