Open the CIPO recordAbstract From the Canadian patent
Used plastic strapping is recycled by feeding successive lengths of strapping to a cutter station that cuts off leading and trailing end portions of the strapping to provide "clean" ends and cuts out any old , lap-joints. The resulting sections of strapping are heat-sealed together to form, "new" continuous strapping that is wound onto a spool for re-use. A single cutter head having upstream and downstream cutters is used to perform all cutting operations. The two cutters move downwardly together and either cut out a lap-joint or a leading or trailing end portion of a length of strapping, depending on what portion of strapping is positioned below the cutter head.

Why it's free to use
- Filed March 31, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 31, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 31, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
