In a method and apparatus for making and inspecting pre-fastened articles, such
as disposable training pants, having at least two generally flexible elements capable
of connection with each other during initial assembly of the article, the elements
are arranged in overlapping relationship with each other and connected together
to define an engagement seam of the article. The article is arranged to define
an interior space thereof whereby the interior space is bounded in part by the
engagement seam. The elements are irradiated at the engagement seam by a radiation
source within the interior space of the article and an image of the irradiated
engagement seam is captured by an image capturing device. In one embodiment, the
image capturing device is positioned within the interior space of the article and
the radiation source is either within the interior space or exterior of the article.
