Abstract: 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.

Abstract: A method of manufacturing a bituminous coating sheet, wherein a bitumen-impregnated core material provided with a layer of backface bitumen is caused to be in contact with one or more rotating bodies during the manufacture. A slip material dispersed/emulsified or dissolved in a liquid is applied onto the bituminous backface layer on the side that is to be brought into contact with a rotating body; and that the liquid is evaporated prior to contact with the rotating body; and that subsequently a further bituminous layer is applied onto the side which is provided with said slip material.
