Abstract: Unfused core forming fibers, indicated at (28), together with the facing sheet (24), are carried by the belt (20) into a thermobonder (22). The thermobonder (22) heats the fibers to a temperature above the melting point of at least one thermoplastic fiber material in the core. This heat fuses the core and also bonds the core to the facing sheet. At forming zone (54), the multilayered or composite web is typically bonded or densified along at least a section of the eventual peripheral edge margin of an article to be formed. Typically, the entire eventual peripheral edge margin of the article is densified. In addition, field bonds are also formed within the eventual field of the article intermediate the peripheral edge margin. The preferred approach is to emboss these bond areas. To this end, opposed sets of embossing rolls (70, 72, 74 and 76) are positioned as shown. The illustrated roll (70) comprises a field bond feature forming roll having a projecting pattern of field bond forming contacts (80) which press against the face sheet and other layers of the composite material.

Abstract translation: （28）所示的未熔融的芯形成纤维与表面片（24）一起被带（20）承载到热连接器（22）中。 热链条（22）将纤维加热到高于核心中的至少一种热塑性纤维材料的熔点的温度。 这种热熔化芯并且还将芯结合到相对的片材上。 在成形区（54），多层或复合纤维网通常沿待形成的制品的最终周缘边缘的至少一部分结合或致密化。 通常，制品的整个最终的外围边缘是致密的。 另外，在边缘边缘边缘的中间的场合，也形成场键。 优选的方法是压印这些粘结区域。 为此，相对的压花辊组（70,72,74和76）如图所示定位。 所示的卷（70）包括具有形成凸起图案的场结合形成接触（80）的场结合特征形成辊，其压靠在面板和复合材料的其它层上。
