Abstract

A method for manufacturing absorbent articles comprises delivering a continuous web assembly including a backsheet material, a liquid permeable bodyside liner material, and an absorbent structure interposed between the backsheet material and the bodyside liner material, the web assembly having a body-facing side and a garment-facing side; attaching a discrete segment of first waist elastic material to the body-facing side of the web assembly; attaching a discrete segment of second waist elastic material to the garment-facing side of the web assembly such that the web assembly is interposed between the discrete segments of first and second waist elastic materials; and cutting the web assembly to form a plurality of absorbent articles.

Dependent claims

A method for manufacturing absorbent articles, the method comprising:

delivering a continuous web of liquid impermeable backsheet material in a machine direction;
delivering a continuous web of liquid permeable bodyside liner material in the machine direction;
providing a plurality of absorbent structures;
attaching the web of backsheet material to the web of bodyside liner material such that the absorbent structures are interposed between the web of backsheet material and the web of bodyside liner material;
delivering a continuous web of first waist elastic material in the cross-machine direction;
cutting the web of first waist elastic material to form a plurality of discrete first waist elastic members;
attaching the first waist elastic members to the web of bodyside liner material in the cross-machine direction;
delivering a continuous web of second waist elastic material in the cross-machine direction;
cutting the web of second waist elastic material to form a plurality of discrete second waist elastic members;
and
attaching the second waist elastic members to the web of backsheet material in the cross-machine direction such that the webs of backsheet material and bodyside liner material are interposed between one of the first waist elastic members and a respective one of the second waist elastic members.

A method for manufacturing absorbent articles, the method comprising:

providing an absorbent assembly including a liquid permeable bodyside liner, and an absorbent structure underlying the bodyside liner material;
delivering a continuous web of chassis material having a body-facing side and a garment-facing side;
attaching the absorbent assembly to the web of chassis material to form a continuous web assembly;
pre-tensioning a first waist elastic material;
attaching a discrete segment of the first waist elastic material while pre-tensioned to at least one of the body-facing side of the chassis material and the absorbent assembly such that the discrete segment is attached in an elongated state;
pre-tensioning a second waist elastic material;
attaching a discrete segment of the second waist elastic material while pre-tensioned to the garment-facing side of the chassis such that the chassis is interposed between the discrete segments of first and second waist elastic materials such that the discrete segment of the second waist elastic material is attached in an elongated state;
and
cutting the web assembly to form a plurality of absorbent articles.
