The present invention provides a method of providing a disposable product with zero waste ear formation and attaching the ears to a running chassis web.

Method for application of nested zero waste ear to traveling web

Methods and apparatus for application of nested zero waste ear to traveling web

The present invention provides a process wherein a rotary knife or die, with one or more cutting edges, turns against and in coordination with a corresponding cylinder to create preferably trapezoidal ears. Ear material is slit into two lanes, one for a left side of a diaper and the other for a right side of a diaper. Fastening tapes are applied to both the right and the left ear webs. The ear material is then die cut with a nested pattern on a synchronized vacuum anvil. The resulting discrete ear pieces however, due to the trapezoidal pattern of the ears, alternate between a correct orientation and an incorrect (reversed) orientation. The reversed ear is required to be rotated 180&#xb0; into the correct orientation such that the ears and associated tape present a left ear and a right ear on the diaper.
