Disclosed is a packaging method, which comprises: when a film (16) having been shaped into a tubular form and packed with packaging articles (10) is end-sealed, as the film is fed, by use of the nonuniform rotational motion of a pair of sealers (40) disposed to oppose each other on the upper and lower sides of the film feeding route, varying the rotation speed of a pair of rotating sealers relative to the timing of feeding the packaging articles corresponding to the cut pitch for cutting the film and the height of the packaging articles within the angle range of at least +/- 90 DEG from the point of engagement of the pair of sealers so that the sealers may not interfere with the packaging articles whereby to control the present position of the sealers; setting the peripheral rotation speed of the sealers such that it may always be higher than the speed of feeding the film; and controlling the peripheral rotation speed of the sealers such that it may correspond to the speed of feeding the film under engagement of the pair of sealers, and an apparatus for practicing said method. |
