Process for the transverse welding of a gusseted tubular sleeve made of heat-sealable plastic, in which at least two separate sleeve parts p1, p2 of the same transverse zone 9 are laid against one another and heated, thus making it possible to fix them to one another in the form of a single welded part p3, characterised in that a sandwiched portion 10 comprising two mutually confronting welded parts p3 separated by an access part 11 is produced in the transverse zone 9 and in line with a gusset 4. <IMAGE> |
