    • A composite structure comprising a preformed flexible laminate in adhering contact with at least a first and second transparent or translucent panel members such as would be useful as an insulated glass unit. The flexible laminate contains an undulating spacer element either partially or totally embedded within a core material and has a polymeric coating on at least one surface thereof. The flexible laminate effectively seals the interior of the panel structure from air and/or moisture and maintains a desired distance between the panels. A multi-cavity extrusion die for forming the preformed flexible laminate has a core cavity for receiving the core material as well as the undulating continuous spacer element. Converging walls within the core cavity serve to embed at least one side of the spacer element in the core material and a land area forms a desired shape or configuration wherein the spacer element undulation is maintained. At least one polymeric feed cavity located downstream from said core cavity and said land area applies a polymeric film or coating to at least a surface of the embedded spacer element. A plurality of optional feed cavities can apply the same or different polymers to additional surfaces of the embedded spacer element and can totally cover or encapsulate the same.
    • 一种复合结构,包括与至少第一和第二透明或半透明面板构件粘合接触的预成型柔性层压材料,例如可用作绝缘玻璃单元。 柔性层压板包含部分或完全嵌入芯材中的起伏间隔元件,并且在其至少一个表面上具有聚合物涂层。 柔性层压板有效地将面板结构的内部与空气和/或湿气密封并且在面板之间保持期望的距离。 用于形成预制柔性层压板的多腔挤出模具具有用于接收芯材料的芯腔以及起伏的连续间隔元件。 芯腔内的会聚壁用于将间隔元件的至少一侧嵌入芯材料中,并且焊盘区域形成期望的形状或构造,其中保持间隔元件起伏。 位于所述芯腔和所述接合区域下游的至少一个聚合物进料腔将聚合物膜或涂层施加到至少嵌入的间隔元件的表面。 多个可选的进料腔可以将相同或不同的聚合物施加到嵌入式间隔元件的附加表面上,并且可以完全覆盖或封装该聚合物。
