The present invention provides a spreader assembly (2) suitable for opening and spreading a fiber strand into smaller strands or individual filaments. The spreader assembly (2) comprises at least one passageway (21) having an inlet opening (211) for receiving said fiber strand and having an outlet opening (232) through which said fiber strand exits said passageway (21), a divergent zone (23) within the passageway (21) having an entrance end (231) and an exit end (232), and at least one through hole (242) connected to the passageway (21) at an angle and suitable for introducing the air flow thereto. In order to increase the efficacy of opening a fiber strand, the angle of through hole (242) is substantially perpendicular with respect to the longitudinal direction of the passageway (21). In order to increase efficacy of spreading the opened fibers, the divergent zone has a flat cross-section and the area of said exit end (232) is larger than the one of the entrance end (231).
