    • A flame resistant to nonflammable composite panel is produced from a nonextrudable core mixture with a pourable, nonflammable filling material and a binder, and on both sides cover strips, flexibly bonded to the core. For a continuous production of the composite panel in one operation, the core mixture is poured onto a flexible lower adhesive film, supported as it runs in, and a pile extending over the entire width forms there. Between the lower adhesive film and a flexible upper adhesive film, likewise supported as it runs in, material of the core mixture is continuously and uniformly drawn through a V gap and compacted there for the first time and calibrated to thickness. The adhesive films containing the precompacted core mixture are adhesively bonded to the continuously fed cover strips. The apparatus comprises a stretching roller for each of the adhesive films, a device for the uniform application of the core mixture, first means for forming a settable running-in angle and the V gap, second means for supporting the lower adhesive film and third means for the concluding pressing and heating, as well as a device for cutting to length.
    • 由不可渗透的核心混合物与可倾倒的不可燃填充材料和粘合剂制成耐火不可燃复合板,并且在两侧上覆盖柔性地粘合到芯上的条带。 为了在一次操作中连续生产复合面板,将芯混合物倒入柔性下粘合剂膜上,当其运行时被支撑,并且在整个宽度上延伸的绒头形成在那里。 在下部粘合剂膜和柔性上部粘合剂膜之间,同样被支撑在其上时,核心混合物的材料通过V间隙连续均匀地拉伸并且首次压实并校准至厚度。 含有预制核心混合物的粘合剂膜粘合到连续供给的盖带上。 该装置包括用于每个粘合膜的拉伸辊,用于均匀施加芯混合物的装置,用于形成可固化的进入角的第一装置和V间隙,用于支撑下粘合剂膜的第二装置和第三装置 用于结束按压和加热,以及用于切割长度的装置。
