ABSTRACT:
Laminates are tested for the presence of small holes. For example, when a laminate is moving through a processing machine in a direction along a length of the laminate, a vacuum is applied to a surface of the laminate and the surface of the laminate is inspected to detect liquid that has penetrated from another surface of the laminate through small holes to the inspected surface.
