Abstract:
A method of producing a succession of self-adhesive labels carried on a length of release backing material, the method comprising the steps of:(a) providing a laminar material which includes a release backing material as a lower layer and an upper layer comprised of a web of self-adhesive backed material or a layer of pressure-sensitive adhesive; (b) depositing a succession of pre-printed labels onto the upper layer of the laminar material and adhering the pre-printed labels thereto, the laminar material being conveyed past a label applying station; and (c) cutting through the upper layer of the laminar material as far as the release backing material thereby to form the required self-adhesive labels; wherein the rate of deposition of the pre-printed labels onto the upper layer is controlled by detecting the position of pre-printed labels, comparing the detected position with a desired position of the pre-printed labels and changing the said rate of deposition in response to that comparison, wherein the pre-printed labels are detected after they have been deposited onto the laminar material.
