FIELD: tobacco industry.
SUBSTANCE: production of homogenized tobacco material for an aerosol generating product. Invention relates to an injection moulding device for producing a cast sheet from a material containing alkaloids, a method for producing a cast sheet from a material containing alkaloids, and to a cast sheet. The injection moulding device for producing a cast sheet from a material containing alkaloids comprises a moulding box configured to receive a suspension; a movable support with a surface and moving along the casting direction; a casting vane configured to pour the slurry contained in the casting box onto the surface of the movable support along the casting direction so as to form a cast sheet of alkaloid-containing material. Moreover, the casting vane contains a corrugated section. By means of the corrugated part of the casting vane, a plurality of corrugations are formed on the cast sheet. The corrugated section of the cast sheet contains ridges or troughs extending in a direction perpendicular to the thickness of the sheet and having a pitch of 0.2 mm to 2 mm. Moreover, the specified sheet has water content of 20% to 80% by weight of the sheet.
EFFECT: increase of the uniformity, integrity and mechanical strength of the cast tobacco web by ensuring a regular and uniform supply of the moulded material.
