Claims (27)
1. Способ формирования растягивающейся структуры для впитывающего изделия, согласно которому: во время вращения первого валика с соединяющими выпуклыми частями, выполненными с интервалами в направлении вдоль окружности на наружной периферийной поверхности, и второго валика, противоположного по отношению к первому валику, в противоположных направлениях вокруг их центральных осей пропускают первый слой из листового материала, второй слой из листового материала и удлиненные упругие и эластичные элементы, расположенные непрерывно в направлении (МD) обработки между этими слоями из листовых материалов, между первым валиком и вторым валиком и сдавливают и нагревают первый слой из листового материала и второй слой из листового материала, помещенные между соединяющими выпуклыми частями первого валика и вторым валиком, для образования соединенных частей листов посредством сварки первого слоя из листового материала и второго слоя из листового материала таким образом, чтобы соединяющие части листов перекрещивались с упругими и эластичными элементами и чтобы между ними были интервалы в направлении (MD) обработки, при этом
формируют канавки, непрерывные в направлении вдоль окружности, на сдавливающей поверхности, по меньшей мере, одного из первого валика и второго валика для приложения давления в, по меньшей мере, зонах, представляющих собой части поверхностей, соответствующих полным оборотам при вращении первого валика и второго валика, и
при этом при сдавливании и нагреве участки, на которых проходят упругие и эластичные элементы, сдавливают и нагревают в местах, включающих в себя канавки, и участки, на которых не проходят упругие и эластичные элементы, сдавливают и нагревают в местах без канавок.
2. Способ по п.1, согласно которому
соединяющие выпуклые части являются удлиненными и проходят в направлении, пересекающем упругие и эластичные элементы, и имеют первые части, сравнительно длинные в направлении вдоль окружности, и вторые части, сравнительно короткие в направлении вдоль окружности, при этом
первые части располагают на участках, включающих в себя участки, на которых проходят упругие и эластичные элементы, и
вторые части располагают на участках, не включающих в себя участки, на которых проходят упругие и эластичные элементы.
3. Способ по п.1, согласно которому соединяющие выпуклые части являются удлиненными и проходят в направлении, пересекающем упругие и эластичные элементы, и имеют выступающие части, выступающие в направлении вращения от обеих определяемых в направлении (CD), поперечном к направлению обработки, сторон участков, перекрещивающихся с упругими и эластичными элементами.
4. Способ по п.1, согласно которому
формируют канавки в зонах, представляющих собой части поверхности, соответствующей полным оборотам при вращении первого валика и второго валика, не формируя никакой канавки в остальных зонах, и
разрезают упругие и эластичные элементы за счет сдавливания и нагрева в зонах без канавок, и во время сдавливания и нагрева не разрезают упругие и эластичные элементы в зонах с канавками.
5. Растягивающаяся структура для впитывающего изделия, содержащая:
первый слой из листового материала;
второй слой из листового материала, противоположный одной поверхности первого слоя из листового материала; и
множество удлиненных упругих и эластичных элементов, предусмотренных между первым слоем из листового материала и вторым слоем из листового материала вдоль направления растягивания с интервалами между ними, при этом
первый слой из листового материала и второй слой из листового материала соединены вместе посредством процесса сварки, который является прерывистым в направлении растягивания и непрерывным в направлении, пересекающем направление растягивания, для образования соединенных частей листов,
упругие и эластичные элементы прикреплены к первому слою из листового материала и второму слою из листового материала посредством процесса сварки для образования соединенных частей листов в местах, перекрещивающихся с соединенными частями листов,
участки первого слоя из листового материала и второго слоя из листового материала, расположенные между соединенными частями листов выпучены в противоположных направлениях для образования складок, когда первый слой из листового материала и второй слой из листового материала стянуты при стягивании упругих и эластичных элементов, и
в одном из первого слоя из листового материала и второго слоя из листового материала в соединенных частях листов в состоянии естественной длины видимая толщина частей, перекрывающих центры упругих и эластичных элементов, составляет 80-100% от видимой толщины частей без упругих и эластичных элементов.
6. Растягивающаяся структура по п.5, в которой
соединенные части листов являются удлиненными и проходят в направлении, пересекающем упругие и эластичные элементы, и имеют первые части, сравнительно длинные в направлении ширины, и вторые части, сравнительно короткие в направлении ширины, причем
первые части расположены на участках, включающих в себя участки, на которых проходят упругие и эластичные элементы, и
вторые части расположены на участках, не включающих в себя участки, на которых проходят упругие и эластичные элементы.
7. Растягивающаяся структура по п.5, в которой соединенные части листов являются удлиненными и проходят в направлении, пересекающем упругие и эластичные элементы, и имеют на участках, перекрещивающихся с упругими и эластичными элементами, выступающие части, которые выступают из обеих сторон в направлении, пересекающем упругие и эластичные элементы, к одной стороне в направлении ширины.
8. Растягивающаяся структура по любому из пп.5-7, для впитывающего изделия, которое представляет собой одноразовый подгузник типа трусов, включающий в себя наружный элемент, образующий переднюю панель и заднюю панель, и внутренний элемент, который прикреплен к внутренней поверхности наружного элемента и включает в себя впитывающий компонент,
при этом передняя панель наружного элемента и задняя панель наружного элемента соединены вместе на обеих боковых сторонах для образования частей с боковыми швами, в результате чего образуются поясной участок, имеющий кольцеобразную форму, участок отверстия для талии, и два отверстия для правой и левой ног, причем
растягивающаяся структура предусмотрена в зоне наружного элемента, включающей в себя, по меньшей мере, обе в направлении ширины, боковые стороны внутреннего элемента, так, что упругие и эластичные элементы размещены в направлении ширины.
