Abstract
A device for depositing in contact roving of pre-impregnated fibers in which at least one roving (F) is, in the course of a deposition sequence, unrolled from a spool (19) or the like, pressed and deposited on the surface (9) to be covered with the help of a deposition roller (11) or the like, then cut when the desired length of roving is deposited. Substantially from beginning to end of each deposition sequence the roving (F) is maintained in contact with the roller (11), the roving being unrolled substantially under only the tension of the roller and deposited and held, at least at the beginning and at the end of the deposition path, pressed against the surface to be covered, and, at the end of the deposition sequence, spacing the deposition roller (11) from the surface (9), then cutting the roving in its portion between the roller and the surface. Useful in the production of structures of composite material.
