Abstract (en)
[origin: US5335572A] The invention relates to a method, an apparatus and sheets of materials for producing marked security threads as are used to increase the protection of documents and papers of value against forgery. The inventive method is for processing, in particular cutting, security threads out of sheets of material in register, the sheets of material being fed to the processing units in exact alignment. The feed principal is based on guiding the sheet of material on at least one edge of the sheet, determining the position relative to one of the edges of the sheet, producing a signal from the determination of position, and positioning the feeding device relative to the processing unit so that the sheet of material runs into the latter in a predetermined position.
