    • A composite insulating panel comprises an external metal skin (1), an internal metal skin (2), and an insulating core (3) of phenolic foam between the skins (1, 2). The insulating panels are manufactured by first conveying one of the metal skins (1) continuously along a flat bed (30) with an outer surface of the skin (1) lowermost. Liquid phenolic insulating foam reactants are then laid down through a lay down device such as a poker (35) onto the first skin (1). The second skin (2) is laid continuously over the liquid insulating foam reactants and the first metal skin (1). A coating is applied to the foam-receiving faces of one and preferably both metal skins to assist in the adhesion of the phenolic foam to the skins. The skins (1, 2) are spaced-apart by spacer blocks (50) which maintain the skins at a desired spacing corresponding to a desired panel thickness, after the skins (1, 2) are assembled. The skins (1, 2) with the foam reactants laid down therebetween are led through the oven (40) in which the foam rises to fill the space between the skin (1, 2). To assist the uniform foam expansion the skins may be locally heated, especially at the side marginal edges. Spacer blocks are preferably heated as these engage both side marginal edges of both skins, during foam expansion.
    • 复合绝缘板包括在外壳(1,2)之间的外部金属表皮(1),内部金属表皮(2)和酚醛泡沫的绝缘芯(3)。 绝缘板通过首先沿着平坦的床(30)连续地输送金属表皮(1)之一,其中皮肤(1)的外表面最下面。 然后将液体酚类绝缘泡沫反应物通过诸如扑克(35)的放置装置放置在第一皮肤(1)上。 第二皮肤(2)连续地铺设在液体绝缘泡沫反应物和第一金属皮肤(1)上。 将涂层施加到一个且优选两个金属表面的泡沫接收面,以有助于酚醛泡沫体与皮肤的粘合。 外皮(1,2)间隔开间隔块(50),后者在组装表皮(1,2)之后,将表皮保持在对应于所需面板厚度的所需间距处。 将铺设在其间的泡沫反应物的表皮(1,2)引导通过其中泡沫上升以填充皮肤(1,2)之间的空间的烘箱(40)。 为了帮助均匀的泡沫膨胀,表皮可以局部加热,特别是在侧边缘。 间隔块优选地被加热,因为它们在泡沫膨胀期间接合两个表皮的两侧边缘。

    • A process and apparatus for producing an article (20) having an inner foam core (36) and an outer layer of flexible web material (10). Flexible web material is dispensed from a roll (12) in a machine direction. The web material enters a forming structure where it is folded into an outer package defining an open interior. Adhesive (34) is supplied from a suitable source (16) to overlapping lateral edges (10e, 10d) of the web material (10) so as to attach the lateral edges together and close the outer package. A liquid foam material is then supplied into the open interior of the outer package. A structure downstream of the foam source maintains the outer package in a selected configuration of the article until the liquid foam material has sufficiently cured. Individual products, such as winding boards, corner boards, tubes and divider boards, may then be cut.
    • 一种用于生产具有内泡沫芯(36)和柔性网状材料(10)的外层的制品(20)的方法和装置。 柔性网状材料在机器方向上从辊(12)分配。 网状材料进入成形结构,其中折叠成限定开放内部的外部包装。 粘合剂(34)从合适的源(16)供应到幅材材料(10)的重叠的侧边缘(10e,10d),以将侧边缘连接在一起并封闭外包装。 然后将液体泡沫材料供应到外包装的敞开内部。 在泡沫源下游的结构将外包装保持在制品的选定构型中,直到液体泡沫材料充分固化。 然后可以切割单独的产品,例如绕组板,角板,管和分隔板。
