A predrying apparatus is incorporated in a filter attachment machine of a filter cigarette manufacturing system, and includes a speed sensor for detecting the traveling speed of tip paper, a movable heater movable toward and away from the tip paper for heating the same, an actuator for moving the movable heater, and a control unit for controlling the operation of the actuator in accordance with the speed sensor output. When it is judged based on the speed sensor output that the tip paper is stopped or traveling at low speed, the movable heater is moved away from the tip paper by the actuator, and when it is judged that the tip paper is traveling at high speed, the movable heater is moved toward the tip paper by the actuator.
