DETECTION OF SMALL HOLES IN LAMINATES |
摘要 |
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 smal l holes to the inspected surface.
