<p>@ A self-adhesive label (32) on a release backing material (17) comprising a sheet (4) which has been folded so that an upper sheet portion (5) covers, and extends over an edge (19) of, a lower sheet portion (6), the upper surface (8) of the upper sheet portion (5) bearing a desired lithographically printed image and the two opposed inner surfaces (9, 10) of the sheet portions (5, 6) bearing a second desired printed image, a support web (13) comprising a self-adhesive backed material (16) carried on a release backing material (17), the lower surface (11) of the lower sheet portion (6) and the lower surface (12) of the extending part of the upper sheet portion (5) being adhered to the upper surface of the adhesive-backed material (16), and a weakened tear line (38) which extends across that part of the upper sheet portion (5) which covers the lower sheet portion (6) whereby the tear line (38) can be torn thereby to unfold the label (32) and reveal the two opposed inner surfaces (9, 10). The invention also provides a method and apparatus for producing such labels in succession on a length of release backing material.</p> |
