Abstract
A method and apparatus for dealing with small areas such as defects in a web of material provide that pre-prepared marking plates with metal inserts are associated with each of the areas to be dealt with, the marking plates being joined to the web of material in such a way that the metal insert covers the area to identify same. The metal insert can be subsequently detected to permit the marked location to be removed from the web or otherwise processed.
