Abstract: Multilayered web stock is directed toward a curved surface and at least one layer of the web stock is heated to a temperature above a glass transition temperature of the at least one layer of the web stock. The heating can occur just before or upon engaging the curved surface. The temperature of the at least one layer remains above the glass transition temperature while engaging the curved surface, allowing reshaping and/or realignment of the at least one layer relative to other layers of the web stock according to conformance to the curved surface. The web stock is cooled before it disengages from the curved surface. The heating can be done with a high power infrared lamp focused into a line across the web stock, and the cooling can be done with a cooled fluid jet. Additionally, a preheater can be employed, and a supplemental cooler can be used.

Abstract translation: 多层网状物料被引向弯曲表面，并且将所述纤维网原料的至少一层加热到所述纤维网原料的至少一层的玻璃化转变温度以上的温度。 加热可以在接合弯曲表面之前或之后发生。 所述至少一层的温度在接合弯曲表面时保持高于玻璃化转变温度，允许至少一层相对于卷材的其它层根据曲面的一致性重塑和/或重新对准。 卷材在与曲面脱离之前被冷却。 加热可以通过聚焦在网状物料上的线中的大功率红外灯进行，并且冷却可以用冷却的流体射流进行。 此外，可以采用预热器，并且可以使用补充冷却器。
