PRINTER OF CIGARETTE MANUFACTURING MACHINE

摘要

A printer of a cigarette manufacturing machine has a concentration sensor (70) disposed between a wrapping section (4) and a cutting section (16) of the cigarette manufacturing machine. The concentration sensor (70) detects the concentration of printing information (PI) of a tobacco rod (TR). Printing information (PI) is printed on a paper web (W) by a printing unit (20) arranged on the upstream side of the wrapping section (4). An adjustment device (62) capable of varying the length of the feed passage of the paper web (W) is further disposed between the printing unit (20) and the wrapping section (4). A concentration signal from the concentration sensor (70) is used to control the operation of the printing unit (20) and the adjustment device (62). As a result, the concentration of printing information (PI) and the reaching timing at which printing information (PI) reaches the concentration sensor (70) are respectively controlled according to the concentration signal.
