Abstract
A packaging method, and an apparatus for carrying out the method, comprises the operation of a conveyor for conveying articles to be packaged, the supply of a packaging film to be formed into a tubular-shaped package for enclosing or packaging the articles to be packaged, and the provision of end sealing mechanisms for sealing the ends of the tubular packages. A central processing unit contains data concerning the cut pitch for cutting the film, the size of the packaged articles, and the like, and accordingly, in order to effect a tight packaging of the articles, whereby the length of the article packages is effectively reduced as compared with conventional packages, whereby less packaging film is utilized, or in other words, the economic usage of the packaging film is maximized, the rotational speed of the end sealing mechanism is varied in a non-uniform manner such that when the end sealer elements of the end sealing mechansim are disposed at predetermined angular positions away from their mutually opposed or engaged position, the rotary speed of the end sealer elements is greater than the film feeding speed, while when the end sealing elements are disposed at predetermined angul…
