A bag maker-packaging machine adapted for use with formers (1) having different sizes uses pull-down belts (2) to pull by suction an elongated film which has been tubularly formed by a former. When a new former (1) is installed, the pull-down belts (2) are moved from specified belt reference positions towards the surface of the film in a tubular form, and the distance travelled by them until they come into contact with the film surface is measured. After the size of the former (1) is thus identified, positions of some of the components such as a guide roller (7) and a turn bar (9) for the transportation of film to the former are adjusted accordingly. Data corresponding to different former sizes may be stored in a memory (28) and compared with the identified size of the former currently installed. The user can see on a display device what kinds of product can be packaged by using this identified former and may also be informed if the memory (28) does not store any data for formers of the identified size. <IMAGE> |
