    Abstract: The invention relates to a device for applying a coating substance to a continuous paper web in a process for producing abrasion-resistant laminates for manufacturing decorative paper. The coating substance consists of a viscous mixture of melamine resin and alphacellulose to which particles of corundum are added, and is applied to the visible surface of the paper. The inventive device includes a deflector roll (2) on which the paper web (1) lies in an area in which it loops around; a metering roll (6) which is arranged parallel to the deflector roll (2) and forms the boundary of a gap with the same, and which is driven synchronously or almost synchronously with the deflector roll; a slit nozzle (7) for applying the coating substance either directly to the paper web (1) on the deflector roll (2) or to the metering roll (6); and a doctor blade of a rectangular piece (9) of flexible rubber type material. This material is fixed on one side by its back edge, parallel to the axes of the two rolls (2,6) and lies loosely on the upper end of the paper web (1) running off of the deflector roll (2).

    Abstract translation: 本发明涉及一种用于在制造装饰纸的耐磨层压板的制造方法中将涂料施用于连续纸幅的装置。 涂层物质由三聚氰胺树脂和藻糖纤维素的粘稠混合物组成,向其中加入刚玉颗粒并施加到纸的可见表面。 本发明的装置包括偏转辊(2),纸幅(1)位于该偏转辊周围环绕的区域中; 计量辊(6),其平行于偏转辊(2)布置并与其形成间隙的边界,并与偏转辊同步或几乎同步地驱动; 用于将涂层物质直接施加到偏转辊(2)上的纸幅(1)或计量辊(6)上的狭缝喷嘴(7); 以及柔性橡胶类材料的矩形件(9)的刮刀。 该材料通过其后边缘平行于两个辊(2,6)的轴线固定在一侧,并且松散地位于从导流辊(2)移出的纸幅(1)的上端。
