ABSTRACT:
A method and apparatus for applying discrete strips of material to both longitudinally opposite segments of a longitudinally extending web, comprising: longitudinally moving the web along a travel path including a helically looped portion having a center axis and passing opposite longitudinal edges of the web in lapping proximity to one another in a lapping zone of the looped portion; applying at least one continuous strip of material to the web by transversely oscillating the strip across the opposite longitudinal edges in the lapping zone of the travel path; and severing the applied strip between the edges in the lapping zone. The method and apparatus of the present invention have utility in forming elastic gathers on fibrous web materials, such as may subsequently be processed for end-use applications such as disposable diapers, panty-type garments and the like.
