摘要： 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. The preferred embodiment of the invention involves developing multiple film sizes; in particular, applying a first extrusion width on C135 film and applying a second extrusion width on APS film; however, the invention can be applied to applying fluids on multiple film and/or material configurations.
摘要翻译：流体的多个宽度可以挤压到材料的部分上，而不需要系统的复杂重新配置或更换挤出装置。在至少一个实施例中，通过改变材料相对于挤出装置沿着与挤出机的侧面相关的方向被引导的角度来提供各种挤出宽度。在一个实施例中，本发明提供了挤压装置相对于材料的位置的操纵，或者通过操纵材料相对于挤压装置的位置。另一实施例提供具有不同尺寸的多个施用器头的单个挤出机。另外的实施例提供具有不同尺寸的多个施加器开口的单个涂布机头部。另一个实施例提供了能够横向移动材料以实现适当的接近角度的挤出装置。本发明的优选实施例涉及显影多个膜尺寸; 特别是在C135膜上施加第一挤出宽度并在APS膜上施加第二挤出宽度; 然而，本发明可以应用于在多个膜和/或材料构造上施加流体。
