Abstract

The present disclosure provides methods of manufacturing a body adhering absorbent article oriented in the machine direction wherein the body adhering absorbent articles have reduced or eliminated curl. The articles are manufactured with reduced curl by selectively reducing or eliminating the shell elastic tension in regions where components of the body adhering absorbent article are to be attached to form the composite absorbent article web. In certain aspects the body adhering absorbent articles are manufactured by supplying an elastic web of shell material having a longitudinal and transverse direction, stretching the web of shell material in the longitudinal direction, deadening at least one region of the stretched web of shell material, attaching at least one absorbent article component to at least a portion of the longitudinal deadened zone to form a composite web material, and cutting the composite web material to form a body adhering absorbent article.

Description

technical field [0001] The present invention relates to a method of making a body-adhering absorbent article in the machine direction having little or no curl. Various methods of constructing individual body-adhering absorbent articles are described that reduce or eliminate the amount of residual stretch that exists in the shell to which the components are attached. Background technique [0002] Various methods have been proposed for making body-adhering absorbent articles. Body-adherent absorbent articles typically consist of multiple components that are laminated to an elastic shell to form a composite web of the individual absorbent article, the elastic shell typically being under tension during assembly . When discrete body-adhering absorbent articles are die-cut from the composite web, the individual articles curl toward the elastic shell material in the region where they are attached to the individual components due to residual stretch that exists in the shell materi...
