Sinar Norma: How ro replace light seals?

I have a Sinar Norma which needs new light seals in the front an rear standards. Has anyone experience in how to replace them, suitable material, etc?

Philip Morgan has a 35$ DVD movie on a complete CLA for the Norma. He regularly lists on Ebay under Sinar. I have the same light Gasket issue on my Normas, however, they are used daily for copy work with a Betterlight and 900 watt Northlights. I must have the right lens boards I did not get any image fogging even with the old gasket material removed. I will contact Philip to see if he has any answers. The original seals are a black braided cord glued into place. I will need to go through my records to see where black flocking paper can be sourced.

Hello !
I had luck replacing light traps on old cameras (same vintage as SINAR Norma) using a large cotton thread used to knit.
Use as little glue as you can otherwise the thred gets hard. And this reduce it's properties.

You glue in black wool or knitting cotton yearn !

Yes. I tend to favor a very heavy gage of cotton thread because it produce less lint.
This method is used in the Agfa's Isolette I and II to seal the back from light leaks.

I wish to thank everybody who has clarified this question

I recently replaced the light seals in my 5x7 and 8x10 Sinar Norma Rear Standards, both sides were replaced. I used the adhesive-backed black foam, of the appropriate thickness. Cut the material with my rotary trimmer in my darkroom. Took a while to do, but a very straightforward procedure. Cleaning and preparing the standards to accept the modern foam strips took the most time. I would not be in a hurry on this.

Came out great, good as new. The 4x5 used a braided black cotton cord, and probably white glue to hold it in it's channel.
