Abstract
A method of producing an elasticized member having two different degrees of stretch, to be used in an absorbent product. The method involves stretching an elastic member by a first amount and securing part of it in the stretched condition to an inelastic web, while a second portion of the elastic member is stretched by a second amount and secured in the stretched position to the first web or to a second web. Differentially stretched products produced by the method can be used to provide advantages in terms of material savings and elasticity effects in absorbent products.
