This invention proposes a new, improved method and apparatus for applying web segments to a traveling web. Ears, or wings, are placed on a running web of disposable diapers. Because these webs are often asymmetrical or otherwise incompatible with the principle of slipping over the surface of a moving vacuum roll, the webs may float from side to side or otherwise be drawn out of square by asymmetrical forces. A vacuum groove is provided on a vacuum roll to counter these effects. Alternatively, a ridge with vacuum about the ridge is provided, also to pull a machine direction line of material into the groove or over the ridge, thereby giving the web some degree of cross-directional stability.
