Paste transfer apparatus for a filter cigarette manufacturing system

Abstract

A paste transfer apparatus for a filter cigarette manufacturing system includes a movable guide roller and a fixed guide roller separated from each other in the traveling direction of tip paper, and a paste transfer roller is arranged between these guide rollers and disposed in rolling contact with the tip paper. A rocking arm having the movable guide roller mounted thereon is always urged in one direction by a spring, and can also be swung in the opposite direction by a rotary actuator through a swing arm and a cam follower. During operation of the manufacturing system, the rotary actuator is driven in accordance with the tip paper traveling speed under the control of a control unit, and thus the rocking arm turns to bring the movable guide roller to a position closer to or farther from the paste transfer roller, whereby the contact angle over which the tip paper is brought into contact with the paste transfer roller is varied to maintain the thickness of paste transferred to the tip paper at a required thickness.
