Abstract

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.

First claim

We claim:

1. A method of creating a disposable product, the method comprising:
providing an extension panel web;
coupling tapes to a first edge and a second edge of said extension panel web;
folding said tapes over said first and second edges of said extension panel web;
bonding said extension panel web to a stretch laminate web at a first portion of said stretch laminate web and a second portion of said stretch laminate web to form a combination web;
slitting and spreading said combination web in a machine direction into first and second combination webs;
slitting said first and second combination webs in a cross-machine direction into first and second discrete combination web portions;
providing a side panel web having a top edge and a bottom edge;
intermittently coupling said first discrete combination web portion to said top edge of said side panel web;
intermittently coupling said second discrete combination web portion to said bottom edge of said side panel web;
folding said first and said second discrete combination web portions over said top and bottom edges of side panel web;
slitting and spreading said side panel web into a top side panel portion and a bottom side panel portion;
removing a portion of said side panel web from said top side panel portion between said discrete combination web portions;
removing a portion of said side panel web from said bottom side panel portion between said discrete combination web portions;
subsequently providing a chassis assembly having a top side portion and a bottom side portion;
intermittently coupling said top side panel portion to said top side of said chassis assembly;
intermittently coupling said bottom side panel portion to said bottom side portion of said chassis assembly; and
cutting said chassis assembly and said side panel portions in the cross-machine direction adjacently to said discrete combination web portions to create a single product.

2. The method of claim 1 , further comprising removal of a portion of said side panel web from said bottom side panel portion between said discrete combination web portions to create a leg contour, said removal step creating a chip of said side panel web for removal.
