  • Patent number: 4838969
    Abstract: A moving web is folded at predetermined lengths at its opposite side portions so that the opposite side portions are opposed to each other at a predetermined angle with its central portion. Then part of each of the opposite folded portions is outwardly folded. These foldings occur so that a first folding line and a second folding line being opposed to each other at each side of the web include portions in non-parallel relationship. Elastic bands are affixed onto the web along the second opposite folded portions longitudinally and substantially in parallel to each other. When the web is flattened from the folded condition, the paired elastic band affixed onto the web at its oppsite sides each has a diagonal orientation symmetrically with respect to the direction in which the web moves.
