soyé

I just wanted to add a word of thanks to everyone who has contributed here; it's been most interesting and enlightening, and I really appreciate your taking the time to contribute to my question.

But Didier's dialect sense has a long history (see P559 below). And "un soyer" is well-known but of doubtful etymology.

There seems to be general agreement that this comes from OF souage 'ornamental border' = ModF suage. But since I can find nothing on the etymology of soyer and I haven't got the requisite reference works at home, I don't know whether it's related or not.

From the discussion, it looks like the standard reference dictionaries like
http://www.dassault-aviation.com/fr/services/lexique-bilingu...
consider only one meaning of "soyage", the one called "double" or "en Z"
http://www.mate-france.fr/medias/files/pliage-trumpf-wila.pd...

so for the other type of "soyage" mentioned here we have to find a term that is not in dictionaries yet, or at least not in the ones I found, I like "swaged" that I saw most often in the meaning of "serti" but without more details or picture of the edges, we may consider "rolled", "bent", "rounded" as suggested by Charles

Well done! That one hadn't occurred to me, but the possible connection is nearly highlighted in this article, which mentions OF 'souage' — though I'm not entirely sure about the connections they make. HOWEVER, it does mention the notion of a 'decorative edge', which rather nicely brings together the 'rolled / beaded edge' and the notion of 'joggling' (in what I presume would have been its original sense of 'wiggly')

It may not be too much of a stretch to suggest an etymological link between "soyage" and "swage". In this particular case, on the basis of Charles' excellent refs. it certainly seems to refer to rolled edges (i.e. the latter meaning), which have the double advantage of providing a smooth surface for the protection of humans and cables, and additional stiffness for the tray.

The first kind, "double soyage", is called joggling, but not the second kind, which is the one we have here. This is why you won't find references to cable trays with joggled edges.

As your own Wikipedia reference says: "Joggling, also known as joggle bending, is an offset bending process in which the two opposite bends are each less than 90°."

Another definition of joggle applied to sheet metal: "A small offset near the edge of a piece of sheet metal. It allows one sheet of metal to overlap another sheet while maintaining a flush surface."

See page 14 of this thesis:

I had not read the discussion, just seen the answers, you had guessed right first, but "soyage" has two different meanings: parallel shifting of a sheet metal edge for welding (should be called "double soyage", sometimes "soyage en Z") and rolling or bending an edge at more than 90° (up to parallel back bending)

I don't believe so; for one thing, they are talking about the 'bords' (not the 'bouts'), and at the level of detail we are discussing in this document, I doubt they'd be going into quite that much detail about actual constructional techniques.
And for another, cable trays are rarely welded together, a simple fishplate join and bolting is often all that is needed.

19:07 Sep 28, 2016 

OK I see what you mean, I was reading it as the cable raceways being soldered together. They often are done side-by-side as well as lengthways - might that be your geometry?

19:00 Sep 28, 2016 

Thanks, yes, in welding, that's what it would be, indeed; but I fail to see how the same thing can be said of the 'bords' of these cable trays; had it been something about welding the lengths end-to-end, I might have understood it — but that doesn't seem to be what they are talking about here.

In metalworking, we used to talk about a 'safe edge' — but without knowing if this is simply machined to be rounded, or actually folded over, I'm a little worried about either under- or over-translating.

Isn't this a rebated or offset lap joint? Diagram at
