摘要： In a double facer in which a one-sided corrugated board and a liner sheet which are web-like and which are superposed with each other are glued to each other while they travels on a heating plate so as to produce a corrugated board, the heating plate has a thin wall thickness so as to enhance the efficiency of heat transfer to a paper sheet which travels on the upper surface of the heating plate, and the heating plate 20 is provided at the lower surface thereof with a heat radiation means (having the configuration that reinforcing ribs 22 are formed at the lower surface of the heating plate in a direction orthogonal to the direction of travel of a paper sheet, having their height which are successively decreased, or several steam through-holes 51 are formed in the heating plate, and are adapted to be fed therein with saturated steam whose pressure or temperature is successively lowered) in order to decrease a temperature difference between the upper surface and the lower surface of the heating plate so as to restrain warping of the heating plate within a tolerance, that is, the value of heat radiation from the upper surface of the heating plate to the one-sided corrugated board k and the liner sheet n is balanced with the heat radiation from the lower surface of the heating plate, thereby it is possible to restrain warping of the heating plate within a tolerance.
摘要翻译：在双面的情况下，将单面瓦楞纸板和网状的衬垫彼此重合，同时在加热板上移动，从而制成瓦楞纸板，加热板具有薄的壁厚，以提高传热到在加热板的上表面上行进的纸张的热传递效率，并且在其下表面上设置有加热板20，该散热装置在加热板的下表面上形成加强肋22的方向与纸张行进方向垂直的方向形成，其高度依次减小，或者在加热板上形成多个蒸汽通孔51 并且适于在其中进给其压力或温度连续降低的饱和蒸汽），以便降低上表面和下表面之间的温差加热板，以便限制加热板在公差范围内的翘曲，即，从加热板的上表面到单面波纹板k和衬垫n的热辐射的值与热辐射平衡从加热板的下表面，由此可以将加热板的翘曲抑制在公差以内。
