A stapler comprising a spool (6) with a (metallic) wire stock (21) wound thereon, which is formed by a continuous wire. The (metallic) wire is forced to displace forwards by an advancement mechanism (9, 18; 8, 10, 11; 23; 12, 16, 27, 33) and is cut to form a fixed length portion (L) each time the stapler is used. This portion of predetermined length (L) is then bent in an U-shape and stapled on the sheets. The cutting, U-shaping and stapling is performed by a device comprising several interacting parts (40, 41, 42, 43, 45, 46, 54, 58, 70). |
