Abstract:
A method for applying at least one web of elastic material in a curvilinear path onto a continuously moving substrate, said method comprising:(a) moving the substrate along the substrate path;(b) supplying the elastic material to an oscillation unit having at least a first roll having a first roll axis, said first roll being mounted for rolling engagement with a surface of a transfer roll, and said first roll pivoting about a pivot axis transverse to the surface of said transfer roll and thus being effective to apply the elastic material to said transfer roll along the curvilinear path, the pivot axis lying in a plane perpendicular to and offset from the first roll axis such that the first roll is operative to pivot while rolling;(c) oscillating the oscillation unit in a path generally transverse to the substrate path;(d) applying the elastic material from the first roll to the transfer roll in a curvilinear path configuration;(e) applying the elastic material, in the curvilinear path configuration, from the transfer roll to the substrate; and(f) bonding the elastic material, in the curvilinear path configuration, to the substrate.
