The invention concerns a crimping unit comprising a blade-holding flap (3) equipped with a crimping blade (32) and a pre-crimping blade (32), a frame (5), a carriage (4) whereon is mounted the blade-holding flap, and at least a motor (m1, m2). The carriage is guided in its movements by at least a rectilinear guiding means (50), thereby ensuring a rectilinear movement of the blade-holder during crimping and pre-crimping.
