  Nous donnons un procede explicite de determination du rang d'un d-tissu non
singulier du plan quelconque a l'aide de sa connexion associee. Une etude de
quelques invariants du tissu est egalement proposee.
  We give an explicit process of determination of the rank of any non singular
planar d-web thanks to its associated connection. A study of some invariants of
the web is also proposed.
