  • Method of and apparatus for making rod-shaped articles of the tobacco processing industry
    Patent number: 4924884
    Abstract: A continuous filter tow is advanced through a combined wrapping and condensing station by an endless belt, and the thickness of the belt decreases as a result of wear. The resistance which the condensed tow offers to the flow of air is measured by a pneumatic detector at the aforementioned station, and the accuracy of such measurement is affected by decreasing thickness of the belt as a result of increasing rate of escape of testing fluid along the belt. Therefore, the thickness of the belt is monitored and signals which are generated to denote the thickness of the belt are used to correct signals which are generated to denote the resistance to the flow of air. The correction involves modifying the signals denoting the resistance to the flow of air to denote a more pronounced resistance proportionally with decreasing thickness of the belt.
