<p>The machine comprises, in the same horizontal plane as the centring pins (11), a closure guide (15), located in the longitudinal axis separating the two chains (3, 4) on the inner side, these closure guides (15) comprising a bar (16) carrying small columns (17, 18, 19) and a vertical support (20) holding a blade (21) which interacts with a rail (27) in order, by folding through 90 DEG , to bring the end male elements (33) inside openings (34), then, by again folding through 90 DEG , bringing these end male elements (33) to penetrate into the clefts (35), the blade (21) then terminating in a helical-shaped surface (29) with an angular deformation of between 0 and 90 DEG over a length which is sufficient to permit definitive hooking of the end male elements (33) behind the clefts (35). <IMAGE></p> |
