  • System, method, and apparatus for providing multiple extrusion widths
    Patent number: 6447178
    Abstract: Multiple widths of fluid may be extruded onto portions of material without requiring a complex reconfiguration of the system or replacing the extruding device. In at least one embodiment, various extrusion widths are provided by altering the angle at which materials are guided with respect to the extruding device along a lateral plane with the extruder. In one embodiment, the present invention provides for the manipulation of the position of the extruding device with respect to the material, or alternately, by manipulation of the position of the material with respect to the extruding device. Another embodiment provides a single extruder with multiple applicator heads of different sizes. An additional embodiment provides a single coater head with multiple applicator openings of different sizes. Yet another embodiment provides an extruding device capable of moving laterally over the material to achieve the proper angle of approach.
