comment représentez-vous une doublure d'ourlet ?

Probably That's certainly literally what it means: a form of lining used inside a hem to stiffen it, particularly (but not exclusively) in tailored garments. So the literal, word-for-word meaning would be correct — but we should maybe be wary of the fact that a specific technical term may exist in FR.

There are a number of good bilingual sewing glossaries out there, and you may even be able to figure it out by looking at some of the excellent FR monolingual glossaries that are also to be found.
