Method and its corresponding device for automatically closing a tubular packaging material containing articles in a closed end portion thereof that hangs below an item supply point, said device characterized in that it includes a closure head provided therein with an orifice to receive the material in the form of a rope, a collection device adapted to pick up a part of the length of the material that extends in the form of a rope between the supply point and the articles and to introduce the portion collected in the form of an orifice rope, a movable tensioning element that can be driven to contact the material and to move it at a point located between the closing head and the supply point and to drag the material through the hole formed in the closure head of the material. Such that the items located in the closed portion of material are dragged upwards against the lower face of the closing head, closure means in the closure head adapted to apply two separate seals to the cord-shaped portion collected thereon, and cutting means adapted to cut the rope-like portion between the seals separated.
