Open the CIPO recordAbstract From the Canadian patent
Individual sheets of a sheet material to be treated which arrive in an arrival sequence, are distributed on two or more adjacently located conveying tracks. The sheets are conveyed along the conveying tracks through a processing station and are sorted thereafter in accordance with their arrival sequence. The distribution of the sheets is based on evaluating utilization of the conveying tracks to minimize the distance between sheets following each other on the same transport track. A throughput for sheets with varying length that is approximately equal to the throughput for sheets of same length is achieved.

Why it's free to use
- Filed April 6, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 6, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 6, 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.
