Open the CIPO recordAbstract From the Canadian patent
A bale bagging method and apparatus are disclosed. Bales are passed through a collapsible tunnel, preferably formed of panels of flexible yet, self-supporting plastic material. A plastic film tube is supported on the tunnel as the bales are passed through. The tube has the same circumference as the bales so that the tunnel is held tightly against the bales. At the rear end of the tunnel is a retaining hoop over which the tube is stretched. Once the tube passes over the hoop, it contracts onto the bale to fit very tightly onto the bale, thus minimizing wind fatigue in the bag.

Why it's free to use
- Filed May 27, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 27, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 27, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
