A method of producing a succession of self-adhesive labels carried on a backing of release material, which method comprises cutting a laminar material which comprises a web coated on its reverse side with a pressure-sensitive adhesive and having a backing of a release material, the cutting being performed in such a manner that all the layers of the laminar material other than the backing layer are cut and so as to cut a succession of spaced label base portions on the backing; applying an adhesive either across the whole of the upper surface of the web or to an area within each label base portion; removing from the backing waste portions of the web outside the label base portions; applying either a folded sheet and envelope, a multiple-ply label or an envelope containing an article to cover that area of each of the label base portions which has been coated with adhesive. |
