Open the CIPO recordAbstract From the Canadian patent
A transport device for planar sheets such as tickets comprises a drive roller (1) and a follower roller (3). The sheet (25) is inserted between the two rollers (1,3). The follower roller is able to pivot on its mountings to bring the sheet to a predetermined orientation by applying a tractive force to it. The mount comprises bracket means (19, 21), two lugs (11,13) and two apertures (15,17) for the lugs. One aperture is in the form of an elongate slot so as to permit transverse movement of the corresponding lug thereby allowing the axis of the follower roller to pivot whilst locating the roller at both ends.

Why it's free to use
- Filed February 19, 1990 and granted February 17, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 19, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 19, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
