(54) Rotary linear stapling machine


(57) A linear stapling machine (10) provided with a stapling fork (21) rotating around a first axis (13) and a die (15) counter-rotating around a second axis (13') that are arranged so that the branches (26) of a wire staple (25) that is carried by the stapling fork (21) can be forced through a product part (16) running through the rotary stapler (10) and be formed against the die (15), as well as that a first guide means (37) is arranged to turn the stapling fork by 90° during its motion to as well as during its motion from a staple pick-up zone (31) in relation to a stapling zone (32) so that the orientation of the stapling fork is parallel to the first axis (13) in the staple pick-up zone (31), but that the stapling fork is perpendicular to the first axis (13) in the stapling zone (32), so that the wire staple upon stapling through the product part (16) is parallel to the direction of motion of the product part, wherein at least one second stapling fork (21') rotating around the first axis (13) and training the first stapling fork (21) is arranged to roll off against a corresponding second die (15') counter-rotating around the second axis (13').
