A security or other image, for example a hologram is applied to a moving, stock (13), e.g. banknote sheets by carrying the images in the form of, transfers on a web (34) which is moved at the same speed as the stock during application but at a lower speed between application steps so as to allow, relatively close spacing of the images on the web. The web is retracted following each application to compensate for distance travelled during acceleration and deceleration during each cycle. The images are transferred by pressure cylinders (46,48) which press the images on to adhesive patches provided on the stock at predetermined positions by applicator rolls (22,26).

Why it's free to use
- Filed February 5, 1991 and granted December 11, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 5, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 5, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
