A model of cardboard canvas formation by water- fibrous suspension spraying method on the “Kivatch” machine was developed. Previous investigators of “Kivatch” machine process concentrated on the problem of dewatering of water- fibrous suspension in centrifugal ejector part of machine, its separation and fractionating in spraying jet. The investigations of “Kivatch” machine as cardboard and paper making machine concerned only jet dynamics, but the direct process of canvas formation on the moving mesh shield of forming part and the influence of technological and constructive parameters on ( пухлость) and roughness is essentially unexplored. In this paper for the first time we try to explain theoretically why the canvas formed by this method possess high bloat (low dencity) and rough surface.
