一种用于生产水蒸汽可渗透的层状片材的方法和装置，包括以下步骤：a）将层状载体片材供给到第一辊，并在载体片材的一侧上在载体的输送方向上的第一位置施加粘合剂 其中所述粘合剂是以熔融状态施加的热熔粘合剂; b）在位于第一位置下游的输送方向的第二位置处，将具有透水性的熔融材料施加到设置有粘合剂的载体片的该侧上; c）将载体片，粘合剂和水蒸汽可渗透材料的复合物压在由第一辊和与第一辊配合的第二辊形成的滚动间隙中; d）在轧制间隙的下游沿着输送方向冷却压制复合材料，并从轧辊装置牵引复合材料。

The invention relates to a method for producing a water vapor-permeable sheet-like web (1), the method comprising the steps of:
a) feeding a sheet-like substrate sheet (2) to a first roll (3) and applying an adhesive (A) (on one side of the base sheet 2) (at a first location I) in conveying direction (F) of the carrier web (2), wherein the adhesive (a) is a hot melt adhesive and in the molten state to the carrier web (2) is applied; b) applying a water vapor permeable molten material (B) provided on the (with the adhesive A) side of the carrier web (2) at a second location (II) in the conveying direction (F) of the carrier web (2) (the first position I) is downstream; c) pressing of the composite of carrier web (2), adhesive (A) and water vapor permeable material (B) in a nip (4) (by the first roll 3) and one (with the first roll 3) cooperating second roll (5 ) is formed; d) cooling of the molded composite (from base sheet 2), adhesive (A) and water vapor permeable material (B) in the conveying direction (F) behind the roll gap (4), and conveying out of the composite of the roller assembly (3, 5). The invention further relates to an apparatus for performing the method.
