A bag maker-packaging machine adapted for use with formers having different sizes uses pull-down belts to pull by suction an elongated film which has been tubularly formed by a former. When a new former is installed, the pull-down belts 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 is thus identified, positions of some of the components such as a guide roller and a turn bar for the transportation of film to the former are adjusted accordingly. Data corresponding to different former sizes may be stored in a memory 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 does not store any data for formers of the identified size.

[ What is claimed is:] [1.] A bag maker-packaging machine for use with installed formers having different sizes, said bag maker-packaging machine comprising:a former for forming an elongated film into a shape of a tubular formed film having a longitudinal axis;pull-down belts for pulling said tubular formed film;belt-adjusting means for moving said pull-down belts from predetermined reference belt positions separate from said tubular formed film towards an inward direction substantially perpendicular to said longitudinal axis of said tubular formed film;measuring means for measuring the distance travelled by said pull-down belts along the inward direction by said belt-adjusting means; andidentifying means for identifying the size of said former from results measured by said measuring means.
