ABSTRACT OF THE DISCLOSURE A method for producing a cylindrical packing sleeve open at one end and closed at the other, more particularly for tampons for feminine hygiene, out of a deformable tear resistant packing material, a section of the said packing material being sucked, by a winding mandrel equipped with suction apertures and, by rotating the said winding mandrel, being wound around it, the resulting over- lapping ends of the said section being connected together to form the packing sleeve and the end projecting beyond the said winding mandrel being closed, whereupon the said packing sleeve is removed therefrom. The method is characterized in that the end of the cylindrical packing sleeve projecting beyond the winding mandrel is secured and is closed, during rotation thereof, and forms a twist. The method makes it possible to produce a constant closure pattern of the pack- ing sleeve, regardless of the shape of the tampon insertion end.
