A nailer device for collated nails (S) comprises an elongated strip (E) almost flat shaped and provided with at least a plurality of first connections (P) projecting therefrom and each provided with a fixing end (F) opposite to the elongated strip (E) and assigned to the removable fixing of a respective nail (N). Said device (1) comprises at least a magazine (3) for at least one collated nails, said magazine (3) leads into a shot chamber (5) and it (3) is provided with a feeding mechanism (7) for feeding the shot chamber (5) with a nail (N) for a time. Said device (1) comprises at least a sliding seat (9) aligned with the magazine (3) and in communication with the shot chamber (5) from which it (9) receives the elongated strip (E) which it (9) puts forward up to a respective outlet for the elongate strip. Said device (1) further comprises at least an outlet duct (11), for the nail, aligned to the shot chamber (5) from which it (11) receives a nail (N) thrusted by a thrusting means (13), aligned with the outlet duct (11), during the stroke of such thrusting means (13) between its extreme internal condition (I) and its external extreme condition (B), through the shot chamber (5) and such outlet duct (11) to eject and fix the nail (N).
The thrusting means (13) is provided with a matching means (15) assigned to match with the fixing end (F) of the first connection (P) previously bearing the fired nail in the stroke of the thrusting means (13) from its external extreme condition to its extreme internal condition to align the first connection (P) of such fixing end (F) to the respective portion of the sliding seat.
