ABSTRACT:
A method and apparatus are disclosed for detecting the continuity of nonconductive coatings on conductive web materials, such as rolls of metallic foils. The coated side of the sheet material web contacts a conductive surface and electrical resistance of the coating is measured. The apparatus for measuring the resistance of the coating may be adjusted to permit small gaps in the coating to be bypassed while being triggered by major gaps in the coating.
