Abstract: The present invention relates to a casting apparatus for the production of a cast web of homogenized tobacco material, said casting apparatus comprising • o a casting box (4) adapted to contain a slurry of said homogenized tobacco material; • o a movable support; • o a casting blade (6) adapted to cast the slurry contained in the casting box onto the movable support so as to form the cast web; • o wherein said casting blade has a transverse cross section defining a blade edge, said blade edge including a first point having a first radius of curvature and a second point having a second radius of curvature, said first and second radii of curvature being comprised between about 1 and about 500 and being different from each other.

Abstract: The present invention is relative to a casting apparatus for the production of a cast web of homogenized tobacco material, said casting apparatus comprising ?a casting box adapted to contain a slurry of said homogenized tobacco material; ?a movable support; ?a casting blade adapted to cast said slurry contained in said casting box onto said movable support in order to form the cast web; ?wherein said casting apparatus further comprises a first, a second and a third actuator coupled to said casting blade in a first, a second and third position, respectively, said first, second and third actuator being suitable to change a distance between said casting blade and said movable support in said first, second and third position, respectively.

Abstract: The invention relates to an apparatus (1) for the production of cast web of homogenized tobacco material, said casting system comprising a casting box (4) adapted to contain a slurry of said homogenized tobacco material and from which a cast web of said slurry is cast; a first drying section adapted to dry said cast web; a movable support to receive the cast web formed by casting said slurry from said casting box and to transport it to said first drying section; a drum (8) adapted to move said movable support and adapted to allow heat exchange between said drum and said movable support; and first temperature control means to cool said drum so that a temperature difference between a temperature of said movable support at a position where said cast web is received onto said support from said casting box and a temperature of said slurry in said casting box is comprised between about 0 degree Celsius and about 30 degrees Celsius.
