Abstract
Methods and apparatus for applying elastic material in a curvilinear pattern on a continuously moving substrate. The method moves a substrate along a substrate path, supplies the elastic material to an oscillation unit first roll mounted for pivoting and rolling engagement with a transfer roll, oscillates the oscillation unit in a path generally transverse to the substrate path, applies the elastic material from the first roll to the transfer roll in the desired curvilinear path configuration, then applies the elastic material from the transfer roll to the substrate and bonds the elastic material to the substrate. Optionally the first roll may apply the elastic material directly to the substrate. Also at least two webs of elastic materials may be applied to a continuously moving substrate in at least two curvilinear substrate paths by supplying the elastic materials to a single transfer roll, applying the elastic materials from the transfer roll to the substrate and bonding the elastic materials to the substrate.
