In a tire vulcanizer, a single long-stroke cylinder is mounted at the central position of a top frame and is, supported to a mounting frame fixedly mounted on the top frame rather than being fixed directly to the top frame. Furthermore a centering mechanism for a pressure plate is provided between the pressure plate and each of opposed side frames so as to adjust the levelness of the pressure plate with respect to both the longitudinal and transverse directions of the pressure plate.

Why it's free to use
- Filed November 29, 1989 and granted December 13, 1994. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 29, 2009.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 29, 2011.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
