Abstract

The invention relates to a paper, cardboard or the like, which coated in at least two stages. At least one side is provided with a double coating. The product is characterized in that 85% of the particles in the covering material of a first-stage coating paste are such that they fulfil a condition L/h higher than 10. The invention relates also to a method of producing a paper, cardboard or the like, coated in at least two stages. The method is mainly characterized in that, between the coating stages, a web (1) to be coated is supported by means of a single element (2) travelling along with said web of paper. The invention relates also to an apparatus for producing a paper, cardboard or the like. This apparatus is characterized by comprising a web-supporting element (2), which travels along with the web for carrying the web in a supported fashion between coating stages (3, 4). The element is e.g. a cylinder installed to be rotatable around its longitudinal axis, the outer periphery of said cylinder touching at least two spreading units (3, 4), mounted at a peripheral distance from each other. A heater (5) can be fitted between said spreading units. <IMAGE>
