Abstract From the Canadian patent

A sleeve for a print cylinder comprising a fiber reinforced thin-walled material and having a seamless surface ready to be covered with a surface material. The sleeve may be used in flexographic printing either as a support for photo-polymerized printing plates or rubber layers. The sleeve has the advantages of having low manufacturing cost and providing the necessary heat resistance to withstand rubber vulcanization temperatures. The sleeve is also airtight and remains properly positioned during printing operations.

Why it's free to use

  • Filed January 17, 2003 and granted July 19, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 17, 2023.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 17, 2025.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
