Abstract
A method of manufacturing a string of bags provided with transverse closure strips by sequentially placing closure system segments transversely on a film for forming the walls of the bag, with each segment having two complementary closure strips. The support webs are fixed respectively to the inside faces of the two walls of the bag while taking care to provide sequential transverse openings in the film so as to give access to between the two strips. A machine for implementing the method and strings of bags obtained thereby are also included.
