Abstract
A stapler for driving staples (12) into a sheaf of papers comprises two guide elements (17, 17', 17'; 18, 18', 18') for internal guidance of the legs (12a) of the staple (12) during the driving of the staple into the object. Each guide element (17, 17', 17'; 18, 18', 18') consists of at least two substantially identical, separate guide parts (17, 17', 17'; 18, 18', 18') successively arranged seen in the driving direction of the staple (12). Each guide part (17, 17', 17'; 18, 18', 18') is movable between a first position, in which it extends into the driving path of the staple (12) to abut against the inside of the respective leg (12a) during the driving of the staple, and a second position, in which it is removed against spring action from the driving path of the staple (12). Each of the guide parts (17, 17', 17'; 18, 18', 18') has a ramp portion (23, 23', 23', 24, 24', 24') for such cooperation with the web portion (12b) of the staple (12) that it is removed by the web portion against spring action as the driving of the staple (12) proceeds.
