Open the CIPO recordAbstract From the Canadian patent
A novel method and installation are proposed for manufacturing rectangular enamelled magnet wire using an in-line rolling and enamelling system. The in-line rolling and enamelling of the magnet wire in a single continuous, operation provides many advantages and eliminates quality programs, inefficiencies and waste which are inherent in the manufacture of shaped magnet wire using separate rolling and enamelling operations. It is particularly suitable for use with the so called "mini" rolling mills which are small and flexible and modular in design.

Why it's free to use
- Filed October 28, 1992 and granted December 29, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 28, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 28, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
