Abstract

The present disclosure provides a method of manufacturing body adhering absorbent articles orientated in the cross-machine direction, body adhering absorbent article having 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, that is stretchable only in the transverse direction, attaching at least one component 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 process for making a body adhering absorbent article in the machine direction orientation with little or no curl. Methods of constructing individual body adhering absorbent articles that reduce or eliminate the amount of residual stretch that exists in the shell at multiple component attachment locations are described. Background technique [0002] Various methods have been proposed for making body-adhering absorbent articles. Body adhering absorbent articles typically consist of multiple parts that are laminated to an elastic shell, usually under tension during assembly, to form a composite web comprising a plurality of individual absorbent articles. When the individual body adhering absorbent articles are die cut from the composite web, due to the residual stretch that exists in the shell material in the lamination region, the individual articles are attached after the shell material has been attached to the multip...
