Abstract: A device for manufacturing a tube skirt from a flexible strip, comprising a housing, a cylindrical elongated mandrel 30, means used to advance and guide this flexible strip to shape it in the form of a sleeve around the mandrel 30, one of the side borders of this strip overlapping the other side border to form an overlapping area to be welded, an inner heating means 32 located in the mandrel 30 to heat the inner face of the overlapping area, and inner cooling means 33 located in the mandrel 30 to cool the inner face of the overlapping area and downstream from the inner heating means 32. The device is characterized in that said cooling means 33 is arranged across from the overlapping area and configured to be in direct contact with the overlapping area.
