Abstract

Apparatus and methods are provided to allow for creation of a configured laminate of a non-woven material, to which a character strip is applied, the character strip exposed by either heat severing and removal of overlying materials, or intermittent application of overlying materials to leave the desired portions of the character strip exposed. A simultaneously formed core insert is applied to a preformed chassis web.

Claims

1. A method of forming a disposable product comprising:

forming an absorbent core;

capturing the absorbent core between a topsheet and a backsheet to form a core insert;

supplying a chassis web;

coupling a stretch material to said chassis web;

coupling an intermittent side panel material to said chassis web over said stretch material;

bonding said side panel to said chassis web;

removing a portion of said stretch film from said chassis web;

coupling said core insert with said chassis web.

2. A method according to claim 1, wherein said topsheet assembly is a three-ply laminate comprising an acquisition layer, a non-woven layer, and a cuff assembly.

3. A method according to claim 1, the method further comprising:

providing waist elastic at a waist cap portion of said chassis web;

folding said waist cap portion of said chassis web over itself and coupling said portion with said chassis web to form a waist elastic portion of said chassis web.

4. A method according to claim 1, the method further comprising:

removing a leg portion from said chassis web;

folding said product and bonding said folded product at side seam locations.
