Abstract: A doctoring apparatus has a flexible doctor blade advanced longitudinally across a surface being doctored. The doctor blade is feed in a continuous length from a storage cartridge and sequentially supported in a blade holder to apply the blade to a moving surface to be doctored. One or both of a pneumatic blade advancing device and a pneumatically operated clamping system are opened and closed in timed sequence with reciprocation of the blade holder longitudinally shifting the doctor blade in a selected direction across the doctored surface. The pneumatic blade advancing device includes an idler roller and a powered roller that co-operate to indexingly advance the doctor blade along the blade path. The clamping system includes a blade cutter to cut the doctor blade and that drives the cut off end of the doctor blade into a discard container.

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.
