  • Patent number: 4960619
    Abstract: A method for applying adhesive to join two surfaces. A nozzle has a body member and a conical tip extending from an outlet face of the body member. A first pair of gas passageways is disposed on a side of the conical tip opposite a second pair of gas passageways. Each of the four gas passageways has a dispensing orifice at the outlet face of the nozzle body. The pairs of passageways are inwardly directed to project streams of gas, preferably air, parallel opposed sides of the conical tip. Thus, the streams of air converge at a distance from the outlet face beyond the apex of the conical tip. These streams of air cradle a stream of material issuing from the apex of the conical tip and cause an oscillatory asymmetric figure eight deposition of material. The deposition on a first surface has a resonant frequency and has smooth, controlled radius turns at its edges. A second surface is then brought into contact with the first surface while the adhesive is still in a fluid state.
