用于与上侧（O）和下侧产生浸渍物，其包括主要的纤维素纤维的现有纤维素片材（1）的方法，（U）（2），其被浸渍以形成具有固化型水性树脂（3）浸渍的芯， 按以下顺序，其特征在于以下步骤：a）将纤维素片材（1）与（3），b）除去在表面上的过量树脂至少上侧（3）（O形成的固化性树脂的一个完整的浸渍）或 下侧（U），c）干燥经浸渍的纤维素片材（1），使得从树脂（3），在上侧的纤维素纤维（2）（O）和/或下侧（U）中，水的蒸发在这之后的 过量的树脂（3）已经被移除，在1至20微米的高度（H）被暴露。

A process for producing a impregnate with an upper side (O) and an underside (U) comprising mainly of cellulose fibers (2) existing cellulosic sheet (1), which is impregnated to form a core impregnated with a curable water-based resin (3), characterized by the steps in the following order:
a) completely soaking the cellulose layer (1) with the curable resin (3),
b) removing the excess forming on a surface of resin (3) of at least the upper side (O) or the underside (U),
c) drying the impregnated cellulosic sheet (1) such that after evaporation of the water from the resin (3), the cellulose fibers (2) on the upper side (O) and / or the underside (U) from which the excess resin (3) was removed over a height (H) of 1 to 20 microns are exposed.
