  We have found that dry grinding tobacco to a fine powder and then mixing with a fluid medium, such as water, without the above grinding or colloid mill action makes possible the formation of an intimate mixture, but when this mixture is applied in a thin layer to a sheet or web forming surface and allowed to dry,bentonite milling the resulting product is a porous sheet of material of low strength not suitable for processing or forming into smoking or other tobacco articles.
  
  However, when the same powder is ground in water or other fluid medium, in the manner described, a colloidal dispersion or sidrry is formed and substantially all of the particles are colloldally dispersible. In this colloidal state the particles of tobacco or colloids evidence other characteristics than in the case of the powder obtained merely by dry grinding to a fine powder, and when the colloidal dispersion or slurry is applied to a sheet or web forming surface,robo sand machine such as a smooth flat surface, endless belt or plate conveyor, or is centrifugally applied upon the interior of a rotating cylinder, there is such an attraction between the several particles forming the slurry, probably due to the immense surface attraction existing therebetween, that when the excess moisture in the spread-out dispersion or slurry is allowed to evaporate, either naturally or by artificial means, a thin dense sheet material or film will form by the agglutination of the particles in the dispersion, which can be removed as sheets or stripped off in webs or filaments and wound on a reel or otherwise handled, depending upon the purpose for which the material is to be used.
  
  As shown in Figure 1, the colloidal dispersion or slurry which has been ground for the proper period is applied in some suitable manner in thin layers to form sheets or in a continuous layer to form webs. We have shown an endless traveling flat plate or belt B upon which the slurry is sprayed by a suitable device 5 in order to form an endless web which is stripped off and wound upon a reel R It has been found that any surface to which our colloidal dispersion of tobacco is applied must not react noticeably with the tobacco or the constituents of the dispersion or else the resulting sheet material will contain spots or marks or general discolorations which greatly decreases its appearance. However, sheets can be formed upon iron or steel plates, as will be obvious despite the above disadvantages. For best results and perfect sheets and webs unmarked by blotches, chromium plated belts, or flat endless bands or equivalent flat endless bands are preferred. In forming sheets, plates made from similar materials or ferrotype plates can be used, such as commonly used in photographic work.
