    • The invention relates to a method for the manufacture of a bituminous coating sheet for a base, wherein a bitumen-impregnated core material (3), on which a layer of rear-face bitumen (4) is applied, is caused to contact one or more rotating bodies during the manufacturing process, and wherein welding bitumen (6) is subsequently applied in zones (200, 600) in order to enable, during application of the sheet on the base, the establishment of pressure equalization channels between the layer of rear-face bitumen (4) and the base. The invention is characterised in that a mixture is provided of a slip material that has been dispersed, emulsified or dissolved in a liquid and a filler material having a grain size that essentially does not exceed 0.15 mm; that the mixture is applied to the layer of rear-face bitumen (4) on the side that is to be caused to contact a rotating body; that the liquid is evaporated prior to contact with the rotating body; and that welding bitumen (6) is applied in zones (200, 600) on the side that is provided with said mixture.
    • 本发明涉及一种用于制造用于基底的沥青涂层片的方法,其中使沥青浸渍的芯材(3)在其上施加有背面沥青(4)的层,以使其接触一个或多个 在制造过程中更多的旋转体,并且其中随后在区域(200,600)中施加焊接沥青(6),以便在片材在基座上施加期间能够在后面的层之间建立压力平衡通道 表面沥青(4)和底座。 本发明的特征在于,将已经分散,乳化或溶解在液体中的滑动材料和基本上不超过0.15mm的粒度的填充材料提供混合物; 将混合物施加到要与旋转体接触的一侧的后面沥青(4)的层; 在与旋转体接触之前液体被蒸发; 并且在设置有所述混合物的一侧的区域(200,600)中施加焊接沥青(6)。
