Open the CIPO recordAbstract From the Canadian patent
A thermoplastic endless belt (100) has a smooth outer surface substantially free of discontinuities and an inner surface with a plurality of teeth (106) at a given belt pitch. The teeth are adapted to engage a pulley (102) with circumferentially spaced sheaves (104) at a pulley pitch greater than the belt pitch. The belt is slightly stretchable so that the pulley can drive the endless belt when engaging the teeth within a range of load on the belt. Means (132 136, 138) are provided to minimize friction between the belt and the drive pulley. Also a position limiter (200) ensures that the driven tooth stays engaged optimally with the drive sheave.

Why it's free to use
- Filed January 19, 2006 and granted April 12, 2016. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 19, 2026.
- Certificates of supplementary protection extend only drug patents, and it isn't classified as one.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
