Open the CIPO recordAbstract From the Canadian patent
A method and apparatus of labeling cylindrical articles feeds labels onto a label drum. The labels have a formed curl such that the leading edge tends to curl away from the surface of the label drum. The article is fed onto the label drum and wrapped by engaging the article with the leading edge of the label and then wrapping the article. An uncut label web can be fed over an edge to impart the desired curl to the label web. The label web is then cut into labels, which are fed onto the label drum. Also the tension of the label , over the edge can be varied so as to vary the amount of curl imparted to the label.

Why it's free to use
- Filed August 13, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 13, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 13, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
