Casting method to check a thickness of a cast sheet with a height detector disposed on a slider

Abstract

The invention relates to a casting apparatus for the production of a cast sheet of homogenized tobacco material, said casting system comprising a casting box adapted to contain a slurry of the homogenized tobacco material; a movable support; a casting system adapted to deposit the slurry contained in the casting box onto the movable support so as to form the cast sheet; a sensor to detect a thickness of the cast sheet; wherein the sensor includes a slider comprising a planar surface adapted to be in contact to a top surface of the cast sheet and a height detector adapted to measure the height of the planar surface so as to derive the thickness of the cast sheet. The invention also relates to a method to measure the thickness of a homogenized tobacco sheet.
