Open the CIPO recordAbstract From the Canadian patent
A pinch welt for trimming a flange formed on a vehicle body panel is disclosed. The welt includes a rigid insert made of a thermoplastic or synthetic rubber material that is compatible with the material of an outer decorative layer of the welt so as to allow the pinch welt to be readily recyclable as a single unit after use. The material of the insert has a resilience that allows the welt to be readily secured to the flange in a resilient manner. The insert is shaped by cooperating continuous forming rolls in an extrusion process that provides oppositely extending tines in which a thin webbing is formed between the tines.

Why it's free to use
- Filed February 6, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 6, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 6, 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.
