ABSTRACT:
A distinctive apparatus and method for applying an elastic strand onto a moving substrate along a selected curvilinear path includes a transporting mechanism for moving the substrate along a selected substrate path and a supplying mechanism for supplying the elastic strand along a selected elastic path. An oscillating mechanism selectively changes a positioning of the elastic strand and includes a slidably movable guide which moves in a direction essentially transverse to said substrate path. The elastic strand slidably travels along the guide which positions the elastic strand such that the elastic strand is selectively applied to the substrate along the curvilinear path. A bonding mechanism selectively applies adhesive in an arrangement which selectively secures the elastic strand to the substrate. A rotatable nip roll contacts the elastic strand and the substrate to press the elastic strand onto the substrate along the curvilinear path.
