в сечении вдоль направления, ортогонального к направлению, в котором простираются герметично скрепленные краевые части, наружный край каждой из герметично скрепленных краевых частей, образованных разрезанием/разделением, имеет дугообразную форму, которая выступает по направлению к внутренней стороне скрепленного сплавлением листового изделия; скрепленная сплавлением часть, в которой листы, образующие скрепленное сплавлением листовое изделие, скреплены сплавлением, образована так, что скрепленная сплавлением часть включает в себя наружный край герметично скрепленной краевой части и расположена внутри скрепленного сплавлением листового изделия по отношению к наружному краю, и в направлении толщины скрепленного сплавлением листового изделия ширина части, скрепленной сплавлением, больше на ее центральном участке, чем на ее обоих концевых участках.
11. Способ изготовления поглощающего изделия, при этом способ включат этап изготовления скрепленного сплавлением листового изделия способом изготовления по п. 1.
12. Способ изготовления поглощающего изделия по п. 11, в котором:
поглощающее изделие представляет собой натягиваемый подгузник одноразового использования, включающий в себя поглощающий комплект и наружный покрывающий элемент, который расположен со стороны не контактирующей с кожей поверхности поглощающего комплекта и к которому поглощающий комплект прикреплен, при этом две части, представляющие собой боковые швы, образованы посредством соединения обеих боковых краевых частей наружного покрывающего элемента в части, размещаемой со стороны живота, и обеих боковых краевых частей наружного покрывающего элемента в части, размещаемой со стороны спины; и
скрепленное сплавлением листовое изделие изготавливают посредством сгибания лентообразного наружного покрывающего элемента в направлении его ширины и облучения заданной части сложенного наружного покрывающего элемента лазерным лучом, и, таким образом, разрезания и разделения лентообразного наружного покрывающего элемента и одновременного образования части, представляющей собой боковой шов.
13. Способ изготовления поглощающего изделия по п. 11, в котором поглощающее изделие представляет собой изделие, в котором верхний лист, образующий контактирующую с кожей поверхность поглощающего изделия, и задний лист, образующий не контактирующую с кожей поверхность поглощающего изделия, соединяют вместе в частях, выступающих наружу от периферийного
края поглощающей сердцевины.
14. Способ изготовления поглощающего изделия по п. 11, в котором поглощающее изделие представляет собой гигиеническую прокладку, и его образуют посредством скрепления сплавлением: верхнего листа и листа гигиенической прокладки, который образует часть в виде крылышка, или листа, образующего часть в виде крылышка, и заднего листа, или верхнего листа, листа, образующего часть в виде крылышка, и заднего листа.
15. Устройство для изготовления скрепленных сплавлением листовых изделий, которое обеспечивает непрерывное изготовление множества скрепленных сплавлением листовых изделий, каждое из которых имеет герметично скрепленные краевые части, посредством облучения лазерным лучом лентообразного листового ламината, в котором множество листов ламинированы, и разрезания и разделения листового ламината, и скрепления разрезанных краевых частей сплавлением, при этом указанные разрезанные краевые части образованы посредством разрезания/разделения в множестве листов, при этом устройство для изготовления содержит:
опорный элемент, который перемещается в заданном направлении в состоянии, в котором листовой ламинат расположен на наружной поверхности опорного элемента, и который имеет часть для прохождения света, через которую может проходить лазерный луч; облучающую головку, которая расположена со стороны внутренней поверхности опорного элемента и которая излучает лазерный луч по направлению к опорному элементу; и средство для приложения давления, которое обеспечивает приложение давления со стороны, противоположной по отношению к опорному элементу, к листовому ламинату, который расположен на наружной поверхности опорного элемента,
при этом опорный элемент включает в себя зону начального удерживания, используемую для удерживания листового ламината перед его облучением лазерным лучом, зону удерживания, используемую для удерживания листового ламината во время облучения лазерным лучом, и зону последующего удерживания, используемую для удерживания листового ламината после его облучения лазерным лучом.
