Open the CIPO recordAbstract From the Canadian patent
An apparatus is provided for improved retention of steel rule dies inserted into slots of a retaining board. A plurality of chambers are oriented substantially perpendicularly to the direction of insertion and have open faces to permit communication with the slots. A spring is located within each chamber and is connected to a ball shaped member located at the open face. Upon initial insertion of the die the ball shaped, member causes the spring to compress. Once the die is completely inserted, the ball/spring assembly exerts a normal force against the die in the direction of the slot wall opposite the open face. Accordingly the inserted steel rule dies are securely held within the slots.

Why it's free to use
- Filed February 7, 1991 and granted August 19, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 7, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 7, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
