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