A web delivery apparatus for a cigarette manufacturing machine and a delivery method therefor

摘要

An apparatus for carrying out a web delivery method is designed so that a web(P) is delivered from a freely rotatable web roll(R) to be supplied to a cigarette manufacturing machine as a pulling roller(10) rotates. This apparatus comprises a powder brake(6) for applying a braking force to the web roll(R), a rotary encoder(8) for detecting the number of revolutions of the web roll(R), a timing sensor(22) for detecting the number of revolutions of the pulling roller(10), a CPU board(24) for calculating the diameter(DR) of the web roll(R) in accordance with detection signals from the rotary encoder(8) and the timing sensor(22), and a control board(28) for controlling the braking force of the powder brake(6) in accordance with various operation modes of the apparatus and the diameter(DR) of the web roll(R).
