摘要： A known method of producing abrasionproof laminate involves depositing a mixture of liquid resin and fine grain corundum on paper web by means of a wire-wound doctor in a reverse coating system or an intaglio printing cylinder. It has been proved that parts of the same application system coming into contact with the mixture soon wear out. According to the inventive method the mixture is delivered to a blast pipe (6) from a container (8) by means of gravity and/or through the effect of a uniform excess pressure produced by an air cushion and applied to the paper web in the form of a thin surplus veil. Without resorting to intermediate pre-smoothing, the surplus is then doctored and removed by a highly concentrated air jet and the remaining coating is smoothed. In the device used to carry out the above-mentioned method, especially the application and doctoring process has no movable mechanical parts. The risk of wear induced by contact with abrasive matter is therefore considerably lower than in known systems. One major advantage is that there is no demixing by sedimentation of fine grain material throughout the entire system.
摘要翻译：的方法是已知为其中液体树脂并用绕线棒，反向涂布系统或网纹辊细粒度刚玉混合物构成被施加到纸幅生产耐磨层压板。已经显示的是，进入与这种涂料体系的混合物组分接触将由磨料颗粒在短时间内被磨损。在新的方法中，从一个容器（8）的重力和/或由一个气垫产生均匀的正压力的作用下，将混合物供给到喷嘴管（6）和作为薄的面纱超过施加到所述纸幅（1）。没有中间预平滑过量由急剧随后刮除聚焦空气的射流和平滑化后的剩余层。当执行新工艺设备的服务，特别是洪水和刮墨刀系统是免费移机零件。因此易感性的磨损通过与研磨材料接触而引起的比已知的系统基本上更小。一个很大的优点还在于，整个系统由细粒材料的沉降排除被分层。

摘要： In conventional methods absorbent base paper is impregnated by being passed through an aqueous solution of the impregnating agent and then conveyed to a drier after the excess has been squeezed off by means of metering rolls. The quantity of resin applied and the residual moisture are checked at set intervals using sample pieces cut out from the web and in the case of deviations the setting of the metering roll or the throughput speed are corrected. The inventive method uses an automatic regulating device. The basis weight of the freshly impregnated, wet web is measured and adjusted to a predetermined control input. The residual moisture of the dried web is measured and adjusted to a set value, for example by influencing the speed of the drying air which is circulated during the last drying phase. The quantity of resin applied is calculated from the basis weight and the residual moisture of the dried web and the basis weight of the untreated web. This is then compared to a set value to give the control input for metering. The method is especially suitable for producing cosmetic films for refining surface of chip board for the furniture industry.
摘要翻译：吸收性原纸浸渍有已知的方法，通过使其通过浸渍剂的水溶液，并随后通过由计量的烘干机的装置夹断的过量供给。以一定的间隔，施加树脂的量和残留水分是在切除的标本验证。在偏差的情况下，所述定量给料辊或运行速度的调节来校正。在新的方法中，提供了一种自动控制。新鲜浸渍湿纸幅的基重被测量并用螺栓固定到一个预定的参考变量。干燥的幅材的残留水分被测量并通过改变循环干燥空气的速度在干燥的最后部分受到影响，例如控制到期望的值。从基础重量和干燥的纸幅和未处理纤维网的单位面积重量的残留水分，所施加的树脂量进行计算，并通过与参考值比较，对于剂量参考变量被确定。该方法特别适用于制造装饰片为刨花板家具工业的表面精加工。

摘要： Die Erfindung betrifft eine Vorrichtung zum Imprägnieren einer durchlaufenden Papierbahn (1) mit einem in Wasser gelösten Harnstoffharz sowie ein entsprechendes Verfahren. Solche Papierbahnen (1) werden z.B. als Möbelfolie oder Fußbodenlaminat eingesetzt, wobei in der bekannten Praxis für ein Verkleben mit einem Substrat ausschließlich Melaminharz verwendet wird. Vorrichtungen zum Imprägnieren weisen viele Umlenkungen auf und haben einen hohen Raumbedarf. Daher hat die Erfindung das Ziel, eine Vorrichtung zum Imprägnieren zu schaffen, die preiswert herstellbar ist und einen geringeren Raumbedarf aufweist. Dies wird dadurch erreicht, dass die Papierbahn (1) zwischen der Antragswalze (7) und dem Trockner (3) in einer im Wesentlichen horizontalen Ebene ohne Umlenkung und ohne Berührung (Unterstützung) geführt ist.
