1. A fiber application head for the production of composite material parts by application of bands formed of several continuous fibers arranged edge to edge, the fiber application head comprising:
a functional module for each fiber of the several continuous fibers, the functional module including cutting means and rerouting means, wherein each functional module is mounted so as to be movable in translation along a compaction direction on a support element of the fiber application head;
a plurality of independent compaction rollers, each compaction roller mounted on one or more adjacent functional modules; and
a compaction cylinder associated with the one or more functional modules associated with a compaction roller for the displacement in translation of the one or more functional modules,
wherein the plurality of independent compaction rollers are arranged in a single row, side by side without contact with each other, wherein a rotation axis of each compaction roller is arranged in a same compaction plane, parallel to the compaction direction, and
wherein the functional module for each fiber of the several continuous fibers includes at least one first functional module and at least one second functional module arranged alternately side by side, each first functional module comprising guiding means able to guide a first fiber towards a compaction roller along a first guiding plane and each second functional module comprising guiding means able to guide a second fiber towards a compaction roller along a second guiding plane, so as to form at the level of the plurality of independent compaction rollers a fiber band formed by first and second fibers arranged alternately edge to edge.
