Abstract

A series of elastic break brakes are provided throughout a travel path of elastics in a machine operation. Elastic strands thread through each individual brake mechanism, and if an elastic strand breaks downstream, a natural snap back of the elastic, which ordinarily travels through the system under tension, drives an immediately upstream cam mechanism back, and holds the elastic thread in place at the elastic break brake immediately upstream of the break as to minimize rethreading required downstream of the elastic break brake.

First claim

We claim:

1. A disposable product comprising:
at least one web of material comprising a front and a back portion of a disposable product, said front and back portions of said disposable product having side areas when worn about the waist of a user, said web of material including at least one leg cutout;
a plurality of elastic strands coupled to at least one of said front and said back portions of said disposable product;
said plurality of elastic strands defining an elastic pattern, said elastic pattern including a first region of each of the plurality of elastic strands running in parallel to one another and parallel to said at least one leg cutout, said elastic strands separated by a first distance and skew to a machine direction from at or near a first side area of said front or said back portion of said disposable product in a first region towards a crotch portion of said disposable product;
a second region of each of the elastic strands running continuously away from said first region and wherein the plurality of elastic strands run parallel to one another, separated by a second distance and in said machine direction across a second, center region of said disposable product, wherein said second distance is larger than said first distance;
a third region of said plurality of elastic strands running in parallel to one another and away from said crotch portion of said disposable product to a third region towards at or near a second side area of said front or said back portion of said disposable product.
