Abstract

Apparatus for inspecting the surface of objects such as band-like running material, which may be metal, paper, or textile, without stopping or reducing the speed of the inspection line, to determine the occurrence of defects. The inspected object surface image and defect data are recorded so that at a desirable later time, the defect data may be reviewed to make a judgement of acceptance or rejection of the object. The apparatus provides an effective control on production.
