Abstract
【解決手段】本発明のシート融着体の製造方法は、支持部材21上に支持されたシート積層体(おむつ連続体10)を加圧部材26を用いて加圧しながら搬送する加圧搬送工程と、照射ヘッド35から支持部材21上の加圧支持されたおむつ連続体10に対して支持部材側開口部27に沿ってレーザー光30を照射して溶断するレーザー光照射工程とを備える。本発明の製造方法は、加圧搬送工程の前に、おむつ連続体10の溶断予定部分10Cの構成を検出する構成検出工程を有する。構成検出工程で、溶断予定部分10Cの構成に不具合が検出された場合、レーザー光照射工程では、不具合が検出された溶断予定部分10Cにレーザー光を照射しないようになっている。
【選択図】図5
