Method of making diaper side panels
View Patent ↗A method of making a plurality of diaper side panels ( 10, 12 ) from a continuous strip ( 40 ). The strip ( 40 ) comprises a central region ( 42 ), a first lateral region ( 44 ), a second lateral region ( 46 ), a first set of fasteners ( 36 ) anchored to the first lateral region ( 44 ), and a second set of fasteners ( 38 ) anchored to the second lateral region ( 46 ). The strip ( 40 ) is separated in the machine direction (M) to form a first set of the side panels ( 10 ) and a second set of the side panels ( 12 ), so that the side panels ( 10 ) each include a fastener ( 36 ) from the first set and the side panels ( 12 ) each include a fastener ( 38 ) from the second set.
1. A continuous strip for making a plurality of diaper side panels, said strip comprising a central region, a first lateral region, a second lateral region, a first set of fasteners anchored to the first lateral region, and a second set of fasteners anchored to the second lateral region;
the central region, the first lateral region, and the second lateral region each running the length of strip in the machine direction (M);
the first lateral region being located on one longitudinal side of the central region and the second lateral region being located on the other longitudinal side of the central region; and
the first set of fasteners being spaced from each other in the machine direction (M), the second set for fasteners being spaced from each other in the machine direction (M);
wherein the central region is an elastic region and is made of a different material, and/or has different properties, than the lateral regions;
wherein the central region occupies between 20% and 90% of the width of the strip in the cross direction (C), with the lateral regions occupying the remaining territory on either side thereof; and
wherein the fasteners are anchored to the longitudinal edge of the respective lateral region and the fasteners extend outwardly away from the central region past the longitudinal edge to which they are anchored.
2. A continuous strip as set forth in claim 1 , wherein the first and second set of fasteners are staggered in the cross direction (C) relative to each other.
3. A continuous strip as set forth in claim 1 , wherein the distal longitudinal edge of the first lateral region and the distal longitudinal edge of the second lateral region defines the width of the strip in the cross direction (C).
4. A continuous strip as set forth in claim 1 , comprising one or more layers coextensive across the central region, the first lateral region, and the second lateral region;
and/or one or more layers non-coextensive across the central region, the first lateral region, and the second lateral region.
5. A continuous strip as set forth in claim 1 , wherein the fasteners in the first set are the same as the fasteners in the second set.
6. A continuous strip for making a plurality of diaper side panels, said strip comprising a central region, a first lateral region, a second lateral region, a first set of fasteners anchored to the first lateral region, and a second set of fasteners anchored to the second lateral region.;
the central region, the first lateral region, and the second lateral region each running the length of strip in the machine direction (M);
the first lateral region being located on one longitudinal side of the central region and the second lateral region being located on the other longitudinal side of the central region; and
the first set of fasteners being spaced from each other in the machine direction (M), the second set for fasteners being spaced from each other in the machine direction (M);
wherein the central region is an elastic region and is made of a different material, and/or has different properties, than the lateral regions; and
wherein the central region occupies between 20% and 90% of the width of the strip in the cross direction (C), with the lateral regions occupying the remaining territory on either side thereof; and
said strip further comprising partial separations dividing the strip into a first set of side panel shapes and a second set of side panel shapes, said partial separations following along a substantially linear path,
the first set of side panel shapes each including a first lateral region with a first fastener anchored thereto and a second lateral region without a second fastener anchored thereto;
the second set of side panel shapes each including a first lateral region without a first fastener anchored thereto and a second lateral region with a second fastener anchored thereto;
the side panel shapes in the first set alternating with the side panel shapes in the second set in the machine direction (M), and
wherein fasteners extend outwardly away from the central region past their respective longitudinal edges.
7. A continuous strip as set forth in claim 6 , wherein the span of each side panel shape is coextensive with the width of the strip in the cross direction (C); wherein the side panel shapes are situated in a no-waste pattern; and wherein the side panel shapes in the first set are the same geometry as the side panel shapes in the second set.
8. A continuous strip as set forth in claim 6 , wherein the substantially linear path extends substantially an entire width of the strip in the cross direction (C).
9. A continuous strip as set forth in claim 6 , wherein the substantially linear path extends substantially an entire width of the strip from a first longitudinal edge of the strip to a second opposing longitudinal edge of the strip.
10. A roll of the continuous strip set forth in claim 6 .
