Open the CIPO recordAbstract From the Canadian patent
There is disclosed a composite label web having feed apertures in its carrier web which enable the composite label web to be advanced in a labeler. The feed apertures are preferably arranged in pairs and each, pair has two equally and oppositely transversely and longitudinally inclined feed faces. The feed faces are engageable by a toothed driver. The feed apertures are spaced from the side edges of the carrier web and are spaced apart to avoid tearing out between the feed apertures. Flap portions of the carrier web resulting from making the feed apertures extend in other than the leading direction. The feed faces assist in keeping the carrier web transversely centered in the labeler.

Why it's free to use
- Filed June 9, 1997 and granted April 24, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 9, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 9, 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.
