The machine comprises arrangement (200, 202) for routing the film (F), and a closing member (300) comprising two support voiles. There is a first longitudinal assembly formed by two complementary sections connected to the support voiles and a second longitudinal assembly located at a distance from the first. The support voiles are brought together between the two longitudinal assemblies so that the distance separating the lateral edges of the two voiles increases as a result of their deformation. Two rectilinear guides (170, 180) are able to penetrate into the space between each pair of lateral edges of the support voiles. |
