Abstract
A nozzle dispenses a material, such as an adhesive, primer, paint, or other coating, through a dispensing port on to a substrate. The spray pattern provided by the nozzle defines, at least in part, an application pattern of the material on to the substrate. An air mask port integral with the nozzle or a separate nozzle expels a mask stream of pressurized gas. The mask stream projects toward the substrate to aid in limiting an application of the material beyond an application line on the substrate. The air-mask port and the dispensing port may be moved relative to the substrate and/or the application line such that the mask stream provides a barrier to the material being applied.
Claims10
A nozzle comprising:
- a dispensing port positioned on the nozzle and effective to dispense a material by a pressurized fluid stream through the nozzle at the dispensing port, wherein the dispensing port is located on a first plane, perpendicular to the pressurized fluid stream;
- and
- an air-mask port, the air-mask port peripherally positioned on the nozzle relative to the dispensing port and effective to expel a pressurized fluid stream through the nozzle at the air-mask port, wherein the air-mask port is on a second plane which is parallel to and offset from the first plane,
- wherein the cross-sectional area of the air mask port in the second plane is smaller than the cross-sectional area of the dispensing port in the first plane.
