摘要： A lamination die apparatus; a method of extruding; and extruded products where two or more laminarly flowing plastic layers are joined in front of an extrusion nozzle, and are simultaneously extruded through the extruded nozzle. The laminarly joined flows are caused to diverge before being extruded through the extrusion orifice. The various layers may be of the same or different material. The layers variously include polyethylene, polypropylene, polyvinylchloride and can have electrical or magnetic particles mixed therein to impart electrical or magnetic characteristics to the film. The die structure may be for blowing tubular film or for the extrusion of flat film. The flat die includes a diverter for diverting a main stream into at least two paths of laminar flow and injecting a central plastic fluid between these two paths.

摘要： Extrusion apparatus for producing laminated products from at least two streams of thermoplastic materials, said apparatus including a flow path leading to a die having a discharge orifice, the thermoplastic materials being introduced separately into the flow path and pass therethrough under pressure in laminar and coextensive streams which flow laminarly and without mixing toward the discharge orifice, without turbulence or friction at the interface between the two streams, and exit therefrom as a laminated film or tube.
摘要翻译：用于从至少两个热塑性材料流生产叠层产品的挤出设备，所述设备包括通向具有排放孔的模具的流动路径，所述热塑性材料被分开地引入到流动路径中，并且在压力下通过层流和共同延伸的流其以层流方式流向排出孔而不混合，在两股流之间的界面处没有湍流或摩擦，并作为层压膜或管从其离开。
