Abstract
An apparatus for C-folding a running length of a covering web such as a polyethylene ribbon about a longitudinally flexible article such as a running length of a core web for making disposable diapers or a stream of longitudinally spaced discrete core segments of such a core web; i.e., a stream of absorbent cores for disposable diapers. The apparatus effects folding each longitudinal edge portion of a covering web downwardly and inwardly about an adjacent longitudinal edge region of the article as the web and the article are forwarded through the apparatus. Each longitudinal edge portion is so folded intermediate a transverse turning member which it passes under, and an oblique turning edge disposed downstream therefrom and over which it passes; and the longitudinal edge portions of the running web and the adjacent longitudinal edge regions of the article become juxtaposed upon passing over their respective oblique folding edges. This is effected without the surfaces of the edge portions of the covering web being contacted by other members of the apparatus; and without unevenly straining the covering web. Preferably the apparatus also gravitationally applies a longitudinally extending bead of a suitable adhesive on the inner surface of each longitudinal edge portion so that adjacent edge portions and edge regions become adhesively secured together upon being juxtaposed.
