Abstract
Disclosed is a method and an apparatus for sorting cylindrical articles such as dry cells and certainly cutting and heat-sealing a cylindrical film of thermal shrinkage resin at a boundary between a film portion enclosing one group and a film portion enclosing the next group in the course of carrying the article groups while keeping each interval between the two adjacent groups. Front side and rear side carrying conveyor belts disposed in front of and behind the upper and lower end sealers in the carrying direction are taken as holding conveyor belts capable of pressing from above the articles. At least one of the holding conveyor belts is movable forwardly and rearwardly relative to the other. A rear end of the front side carrying conveyor belt is positioned behind a front end of the rear holding conveyor belt in the carrying direction in a state in which the upper and lower end sealers are most separated from each other, and both the carrying conveyor belts are moved in the direction in which the carrying conveyor belts are separated from each other as the upper and lower end sealers are gradually moved closer to each other.
