1. An application head for automated fiber placement, comprising at least:
an application roller that is intended to apply fibers to a shaping tool which application roller is rotatably movable on its axis for applying fibers to the shaping tool, and
a feed device comprising a winding of a strip of fibers having a predefined orientation, said strip of fibers being configured to be transferred by unwinding from the feed device onto the application roller with at least one portion of the fibers of the strip being oriented such that they are not perpendicular to the axis of the roller, the strip having a width measured along the axis of the roller,
wherein the head further comprises at least a second feed device capable of supplying one or more ribbons of fibers configured to be transferred from the second feed device to the application roller with the fibers of this or these ribbons oriented perpendicular to the axis of the roller, the width of the strip being greater than the width of each of the ribbons which is measured along the axis of the roller.
