15P 1 15,608 WAIST ELASTIC APPLICATOR FOR DIAPER OR SIMILAR ARTICLE ABSTRACT OF THE DISCLOSURE The invention is an apparatus for applying a tensioned elastic ribbon or ribbons transversely of a moving web of material. It is particularly well adapted for applying elastic to the waist zones of disposable diapers moving continuously in an end-to-end assembly. The apparatus has a supporting frame with a shaft providing an axis of rotation for at least one rotatable radial arm. A polygonal head is mounted at the end of each arm. This has a number of peripheral edges with clamps or vacuum orifices for holding a tensioned strand or strands of elastic ribbon. A drive rotates the radial arms and a rotating mechanism moves the heads (360/n)° for each full rotation of the radial arms where n is equal to the number of peripheral faces on the head. An anvil acts against the head at the time of application of the tensioned elastic to the moving web. The web is passed between the head and the anvil along a path describing a chord or tangent of the circle of rotation of the radial arms.
