Developpantes,

[invite286face9]

Hello,
The translation from French to English of the following terms is a problem to me to be sure of the exact correspondance:

(1) Les Developpantes d'un arc,
(2) Les Developpées d'un arc,
(3)La Developpable des tangentes,

The English terms "Involute", "Evolute", Evolvent" or also "anti-clothoid" seem to be involved but I look for the appropriate english termonology,

Is there someone to help me?
Thanks in advance for your skills and help.
Thierry
