d'anglaisage means spliced, and plaited means something similar to spliced, so I think this is it. 9Assuming you mean baguette and not baquette)

This might be wild and wacky, but in the context of furniture, "anglaisage" can mean "selvedge" which is a non-fraying fabric edge (usually woven but can also be glued).
I am taking "baquette" as a diminutive of "bac". ????
Hence: a trough for the purpose of creating glued selvedge edges.

Having said that, more context would be useful!

Lexis defines:
angléser - Agrafer du tissu mural dans un angle au moyen de bandes de carton.
anglésage - 'Des bandes d'anglésage'

Which is what you see on video, on what looks like a bedhead, if you Google "anglaisage".

Of "anglaiser", Lexis says:
"Sectionner les muscles abaisseurs de la queue d'un cheval pour qu'elle se tienne horizontale".

(And it's the FRENCH that have a reputation as great lovers!)

Still working on the translation.

I reckon someone's got "chipboard" in their uncritical and uncriticized translation memory :
nommément cartons de bois bruts, enduits et plaqués, panneaux d’isorel, CARTONS A ANGLESER, panneaux laminés et contreplaqués, et contreplaqué à âme en bois sous forme travaillée et non travaillée;

namely raw, coated and veneered woodboards, hardboards, CHIPBOARDS, laminated and plywood boards and wood-core plywood in processed and non-processed form;

Now this is more like it:

Fixing device for a covering (9), especially a covering of a seat, comprising on the one hand a profiled section (1) having longitudinal slots (15), and on the other hand an EDGING WIRE (17, 17a) bent at at least two places to form fasteners (19, 19a) intended to cooperate with the slots, the fasteners (19, 19a) lying generally in a plane inclined to the axis of the EDGING WIRE (17, 17a)
L'invention a pour objet un dispositif de fixation de revêtement qui comporte d'une part un profilé muni de fentes longitudinales et, d'autre part, un FIL D'ANGLESAGE replié en au moins deux points pour former des agrafes de fixation destinées à coopérer avec les fentes, chaque agrafe étant située de manière générale dans un plan incliné par rapport à l'axe du FIL D'ANGLESAGE
