The quality of cigarettes advancing along a manufacturing line is tested by a method that includes the steps of checking key characteristics of the cigarettes as they pass through testing units placed at given points along the line, so as to obtain first signals reflecting the quality of the tested characteristics presented by each cigarette, inhibiting the operation of reject devices to prevent defective cigarettes from being ejected, then taking up a given number of tested cigarettes as samples at the outfeed stage of the line, including defective cigarettes, and directing them into an auxiliary off-line testing unit by which they are checked a second time so as to obtain a second signal reflecting the quality of the same characteristics; the method also includes the step of sending a signal to the in-line testing units so that, if the first signals differ from the second signals, the in-line units can be recalibrated, thereby optimizing the quality of the cigarettes produced on a given manufacturing line or in a particular batch, and minimizing rejects.
A method of testing the quality of production in a line for manufacturing tobacco products, comprising the steps of
Equipment for testing the quality of production in a line for the manufacture of tobacco products, comprising at least one testing unit placed along the manufacturing line and serving to examine and check at least one characteristic of tobacco products advancing along the line, in order to obtain a first signal reflecting the quality of the tested characteristic presented by each product, also a sampling device placed to take up a predetermined number of tested tobacco products from the outfeed stage of the line and direct them into an auxiliary testing unit installed off-line, such as will examine and check the at least one characteristic in order to obtain a second signal reflecting the quality of the tested characteristic presented by each product, wherein the auxiliary testing unit is connected to the at least one testing unit operating in-line, able to compare the first signal and the second signal and programmed, in the event of the first signal reflecting the quality of the testing characteristic differing from the second signal reflecting the quality of the tested characteristic, to send a correction signal to the at least one in-line testing unit for the purpose of effecting the calibration of the selfsame unit.
