The webs are twisted in one direction to form a seal at one side of a sleeve and later twisted in the opposite direction to form the seal at the opposite side of a sleeve, such that all of the sleeves are oriented in the same direction, such as with the large openings of the sleeves facing upwardly and the smaller openings of the sleeves facing downwardly.
