Open the CIPO recordAbstract From the Canadian patent
In a rolling mill, a reforming chamber is positioned to receive rings of hot rolled steel rod descending along a vertical path from the delivery end of a conveyor onto a support on an underlying carrier. The carrier has an upstanding stem around which the rings accumulate to form a cylindrical coil. First, interceptor elements operate above the carrier to interrupt the descent of rings, and second interceptor elements supported on the carrier beneath the first interceptor elements operate to subdivide the coil being formed around the stem into upper and lower segments, with a gap therebetween occupied by the second intercepting elements.

Why it's free to use
- Filed November 27, 1997 and granted August 28, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 27, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 27, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
