Abstract

A core forming unit feeds a core to a cutting unit, where a core is wrapped with a core topsheet and backsheet. The core insert is folded and a front wing web and a back wing web are coupled to the folded core. If a pant type diaper is desired, side seams of the front wing web and back wing web are bonded together at side seam regions. Next, portions of the front wing web and back wing web are folded over to create a compact product for packaging and shipment.

Claims

1. A method of forming a disposable product comprising:

forming a core;

folding said core;

creating individual front wing segments from a cross-machine directional stretch front wing web;

creating individual rear wing segments from a cross-machine directional stretch rear wing web;

coupling one of the front wing segment to said folded core;

coupling one of the back wing segment to said folded core;

bonding two side seams, one on either side of the core, of said front wing segment to two side seams of said back wing segment.

2. A method according to claim 1, said method further comprising wrapping said core with at least one of a core topsheet and a core backsheet prior to folding said core.

3. A method according to claim 1, said method further comprising folding over at least a portion of said front and back wing segments outboard of said core in a cross machine direction.
