    • Apparatus for applying adhesive onto flutes of single facers of corrugated media, so that the single facers may be adhered together and to a facing to form a composite web, comprises a plurality of adhesive applicator rolls, each for applying adhesive to the flutes of an associated one of the single facers. The actual speed of travel of the single facers passing across the applicator roll peripheries is sensed, and the rate of rotation of each roll is independently and accurately controlled, in accordance with the sensed speed, to apply a desired amount of adhesive onto selected areas of the flutes. The independent accurate control over applicator roll speeds enables minimum amounts of adhesive to be applied onto the flutes of the individual single spacers, as determined by their configurations and consistencies, while still ensuring proper adhesive of the single facers one to the other ad to the facing. Applying minimum amounts of adhesive onto the flutes reduces both the amount of adhesive required and moisture added to the single facers, so less heat is required to set the adhesive. In addition, minimizing moisture added to the single facers substantially eliminates warping of the composite web and "ribbing" on its outer surfaces, so the surfaces are very smooth and very high quality printing and graphics may be applied onto the surfaces.
    • 用于将粘合剂施加到波纹介质的单面平面的凹槽上的装置,使得单面可以粘附在一起并且面向上形成复合网,包括多个粘合剂施加辊,每个粘合剂施加辊用于将粘合剂施加到相关联的凹槽 单面之一。 检测穿过施加器辊周边的单个平面的实际行进速度,并且根据感测到的速度独立和精确地控制每个辊的旋转速率,以将期望量的粘合剂施加到选定的区域上 长笛。 独立精确地控制施加器辊速度使得最小量的粘合剂被施加到各个单个间隔件的凹槽上,如其构型和一致性所确定的,同时仍然确保单面相对于另一个面向适当的粘合剂 。 将最少量的粘合剂施加到凹槽上减少了所需的粘合剂的量和添加到单面的水分,因此设置粘合剂需要较少的热量。 此外,最小化添加到单面的水分基本上消除了复合织物的翘曲并且在其外表面上“加筋”,因此表面非常光滑,并且可以将非常高质量的印刷和图形施加到表面上。
