Method of incorporating oscillating elastic into disposable garments

A method for manufacturing a plurality of pant-like disposable absorbent garments, the method defining a longitudinal machine direction and a transverse cross-machine direction, the method comprising:

• supplying an elastomeric laminate web traveling in the machine direction and comprising an elastomeric layer and at least one nonwoven layer, the laminate web defining first and second edges extending in the machine direction, and the laminate web defining a slit line extending in the machine direction and positioned transversely between the first and second edges;
• supplying a continuous first leg elastic member and a continuous second leg elastic member, both leg elastic members traveling in the machine direction;
• attaching the first leg elastic member to the laminate web in a first pattern;
• attaching the second leg elastic member to the laminate web in an oscillating second pattern, wherein the oscillating second pattern defines one period per product pitch;
• supplying a continuous leg elastic covering web traveling in the machine direction;
• attaching the leg elastic covering web to the laminate web so as to sandwich both the first and second leg elastic members between the laminate web and the covering web, thereby creating a composite chassis web;
• longitudinally slitting the composite chassis web with a slitter along the slit line to split the composite chassis web into a first body panel web and a second body panel web;
• moving the first body panel web transversely away from the second body panel web to define a gap therebetween;
• attaching a first end of an absorbent composite to the first body panel web and attaching a second end of the absorbent composite to the second body panel web such that the absorbent composite bridges the gap between the first and second body panel webs, thereby defining a composite garment web;
• folding the composite garment web along a centerline that extends in the machine direction, such that the first edge is brought into close proximity with the second edge;
• attaching the first body panel web to the second body panel web along a series of garment side seam bonds spaced apart in the machine direction;
• and
• cutting the composite garment web at a series of cut locations spaced apart in the machine direction to create the plurality of pant-like disposable absorbent garments.

A method for manufacturing a plurality of pant-like disposable absorbent garments, the method defining a longitudinal machine direction and a transverse cross-machine direction, the method comprising:

• supplying an elastomeric laminate web traveling in the machine direction and comprising an elastomeric film layer and at least one nonwoven layer, the laminate web defining first and second edges extending in the machine direction, and the laminate web defining a slit line extending in the machine direction and positioned transversely between the first and second edges;
• supplying a continuous first leg elastic member and a continuous second leg elastic member, both leg elastic members traveling in the machine direction;
• attaching the first leg elastic member to the laminate web in an oscillating first pattern, wherein the oscillating first pattern defines one-half of a period per product pitch, and wherein the first leg elastic member crosses the slit line once per product pitch;
• attaching the second leg elastic member to the laminate web in an oscillating second pattern, wherein the oscillating second pattern defines one-half of a period per product pitch, and wherein the second leg elastic member crosses the slit line once per product pitch;
• supplying a continuous leg elastic covering web traveling in the machine direction;
• attaching the leg elastic covering web to the laminate web so as to sandwich both the first and second leg elastic members between the laminate web and the covering web, thereby creating a composite chassis web;
• longitudinally slitting the composite chassis web along the slit line by a slitter to split the composite chassis web into a first body panel web and a second body panel web, wherein both the first and second leg elastic members are cut by the slitter at the slit line;
• moving the first body panel web transversely away from the second body panel web to define a gap therebetween;
• attaching a first end of an absorbent composite to the first body panel web and attaching a second end of the absorbent composite to the second body panel web such that the absorbent composite bridges the gap between the first and second body panel webs, thereby defining a composite garment web;
