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.

1. A method of manufacturing body adhering absorbent articles orientated in the cross-machine direction comprising the steps of: a. supplying a pair of adhesive transfer layers comprising a lower peel strip, a nonwoven carrier, a body attachment adhesive, and an upper peel strip;b. supplying an elas
1. A method of manufacturing body adhering absorbent articles orientated in the cross-machine direction comprising the steps of: a. supplying a pair of adhesive transfer layers comprising a lower peel strip, a nonwoven carrier, a body attachment adhesive, and an upper peel strip;b. supplying an elastic shell web having a longitudinal and transverse direction and a pair of opposing peripheral edges extending in the longitudinal direction;c. attaching the pair of adhesive transfer layers to the opposing peripheral edges of the elastic shell web;d. attaching at least one absorbent structure component to the shell web interior to the opposing peripheral edges to form a composite web material; ande. cutting the composite web material to form a body adhering absorbent article having a predetermined size and shape. 2. The method of claim 1 wherein the absorbent structure-component is selected from the group consisting of a composite absorbent structure, a barrier layer, a body adhering adhesive, an absorbent and containment flaps. 3. The method of claim 1 wherein the steps of attaching comprise laminating, adhesive attachment, thermal bonding, pressure bonding or ultrasonic bonding. 4. A method of manufacturing body adhering absorbent articles orientated in the cross-machine direction comprising the steps of: a. supplying an activatable web of shell material having a longitudinal and transverse direction;b. supplying a pair of adhesive transfer layers comprising a lower peel strip, a nonwoven carrier, a body attachment adhesive, and an upper peel strip;c. intermittently activating a portion of the web of shell material in the longitudinal direction to create activated and nonactivated portions of the web of shell material in the transverse direction;d. attaching at least one of the pair of adhesive transfer layers to at least one nonactivated portion of the web of shell material;e. attaching at least one component to at least one nonactivated portion of the web of shell material to form a composite web material; andf. cutting the composite web material to form a body adhering absorbent article having a predetermined size and shape. 5. The method of claim 4 wherein the at least one component is selected from the group consisting of an adhesive transfer layer, an absorbent structure, a barrier layer, a body adhering adhesive, an absorbent and containment flaps. 6. The method of claim 4 wherein the activatable web of shell material is a mechanically activatable web of shell material. 7. The method of claim 6 wherein the mechanically activatable web of shell material is a composite comprising at least one inelastic material and at least one elastic material. 8. The method of claim 4 wherein the activatable web of shell material is a mechanically activatable web of shell material and the step of activating comprises mechanically activating the web of shell material by passing the web of shell material through a pair of interconnecting grooved rolls. 9. The method of claim 4 wherein the activatable web of shell material is a heat activatable web of shell material. 10. The method of claim 9 wherein the activatable web of shell material is a heat activatable web of shell material and the step of activating comprises intermittently heating the web of shell material. 11. The method of claim 9 wherein the step of activating comprises passing the web of shell material through an apparatus configured for zoned heated compression of the web of shell material. 12. The method of claim 4 wherein the step of attaching comprises laminating, adhesive attachment, thermal bonding, pressure bonding or ultrasonic bonding. 13. A method of manufacturing a body adhering absorbent article orientated in the cross-machine direction comprising the steps of: a. supplying a web of shell material having elastic and inelastic zones;b, supplying a pair of adhesive transfer layers comprising a lower peel strip, a nonwoven carrier, a body attachment adhesive, and an upper peel strip;c, attaching at least one of the pair of adhesive transfer layers to at least one of the inelastic zones of the web of shell material;d. attaching at least one component to the inelastic zone of the web of shell material to form a composite web material; ande. cutting the composite web material to form a body adhering absorbent article having a predetermined size and shape. 14. The method of claim 13 wherein the at least one component is selected from the group consisting of an absorbent structure, an adhesive transfer layer, a barrier layer, a body adhering adhesive, an absorbent and containment flaps. 15. The method of claim 13 wherein the step of attaching comprises laminating, adhesive attachment, thermal bonding, pressure bonding or ultrasonic bonding. 16. A method of manufacturing a segmented body adhering absorbent article comprising the steps of: a. supplying two webs of activatable shell material;b. activating the two webs of shell material;c. attaching a web comprising an adhesive transfer layer comprising a lower peel strip, a nonwoven carrier, a body attachment adhesive, and an upper peel strip to the two activated webs of shell material;d. attaching an absorbent component to the two webs of shell material to form a composite web material; ande. cutting the composite web material to form a segmented body adhering absorbent article having a predetermined size and shape. 17. The method of claim 16 wherein the absorbent component is selected from the group consisting of an absorbent structure, an adhesive transfer layer, a barrier layer, a body adhering adhesive, an absorbent and containment flaps. 18. The method of claim 16 wherein the activatable web of shell material is a mechanically activatable web of shell material and the step of activating comprises mechanically activating the web of shell material by passing the web of shell material through a pair of interconnecting grooved rolls. 19. The method of claim 16 wherein the activatable web of shell material is a heat activatable web of shell material and the step of activating comprises intermittently heating the web of shell material. 20. The method of claim 16 wherein the step of attaching the absorbent component comprises laminating, adhesive attachment, thermal bonding, pressure bonding or ultrasonic bonding.
