Abstract
A method of applying a film to a handrail of an escalator or moving walkway is provided. The film can be a single or double layered film. Printed matter, e.g. advertising, can be applied to or between the films. A method of removing the film is also provided. The two methods can be effected using a suitable apparatus, that relies on the motion of the handrail to unroll a supply of the film, with one or more rollers pressing the film onto the handrail, or takes off the film from the handrail.
