Abstract:
1. A fiber application head, intended to be mounted at an end of a displacement system in order to apply to a surface a wide strip formed of a number of fibers, comprising: an application roller for applying the fibers in the form of a strip; means for guiding fibers on said roller; cutting means adapted to cut the fibers upstream of the application roller, said cutting means including blades activated by activation systems between a rest position and an active cutting position; and rerouting means placed upstream of the cutting means, said rerouting means including kicking rollers activated by activation systems between a rest position and an active position so as to flatten the fibers against at least one drive roller, the kicking rollers and their associated activation systems being placed on the side of the roller relative to the fibers, wherein said blades and associated activation systems are all placed on the side of the roller relative to said fibers, such that the blades are placed facing the surface of the fibers coming against the roller, and wherein the guide means include first and second guide means arranged in staggered rows along two guide planes that grow closer to each other from upstream to downstream in order to guide the fibers towards the roller in the form of two layers of fibers, and in that the and wherein the cutting means include first and second cutting means, the blades of the first cutting means being able to cut individually the fibers of the first layer guided by the first guide means, and the blades of the second cutting means being able to cut individually the fibers of the second layer guided by the second guide means while passing between the first guide means.
