Abstract: The method consists of the following stages: a) Immersion in water b) Pressing between rollers, controlling their attractive stress so as to obtain a moisture content 20% or more c) Depositing of adhesive in a quantity of 60 mg/m or less d) Drying In this way, the water contained in the sheets of reconstituted tobacco limits the amount of water that it may absorb during gumming, so that the linear weight of adhesive required for a satisfactory performance of the end product is reduced.

Abstract: The invention relates to a method for detecting the vibrations of a roll stand (1) equipped with a hydraulic jack (6) as a device for adjusting the rolling rolls (4, 5). The hydraulic jack comprises a sensor (64) for measuring the position of the mobile portion relative to the fixed portion, this sensor supplying a digital signal (POS). In the method of the invention, the vibrations are detected by direct observation of the position signal (POS) and a comparison thereof relative to a spatio-temporal window (F) whose dimensions are determined as a function of the frequency to be detected. In accordance with the invention, it is possible to define different observation windows (F) suitable for the detection of different vibratory phenomena.
