METHOD AND APPARATUS FOR ADHERING ELASTIC BAND ONTO A MOVING WEB

摘要

A moving web (10) is folded at its predetermined length 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 (13) and a second folding line (14) being opposed to each other at each side of the web (10) include portions in non-parallel relationship. Elastic bands (12) are affixed onto the web (10) along the second opposite folded portions longitudinally and substantially in parallel to each other. When the web (10) is flattened from the folded condition, the paired elastic band (12) affixed onto the web (10) at its opposite sides each has a diagonal orientation symmetrically with respect to the direction in which the web (10) moves.
