A method of producing a succession of self-adhesive labels on a length of release material, which method comprises the steps of: (a) applying a layer of pressure- sensitive adhesive to a surface of a length of release material; (b) applying a succession of individual folded sheets to the layer of pressure-sensitive adhesive so as to adhere the folded sheets to the release material, each folded sheet having an upper panel and a lower panel; (c) applying to the succession of folded sheets on the release material a web of a self-adhesive laminar material whereby the laminar material is adhered by the self-adhesive surface thereof over the succession of folded sheets; (d) cutting through the laminar material, the folded sheets and the pressure- sensitive adhesive as far as the release material thereby to form the self-adhesive labels, the cutting step being carried out whereby the upper panel of the folded sheet with the laminar material adhered thereto can be pulled away from the lower panel thereby to open the label; and (e) removing from the release material waste portions of the laminar material, of the folded sheets and of the pressure-sensitive adhesive which surround the self-adhesive labels. The invention also relates to self-adhesive labels.
