A wire or band strapping machine comprises a driven roll pair for feeding a wire or band toward a guide loop about an object to be strapped, a driven roll pair for reversing the direction of movement of the wire or band to draw the same out of the guide and about the object, and tension means for tightening the wire or band in that reversed direction. The tension means is disposed between the two roll pairs, with the feeding pair disposed closer to the loop than the reversing pair with respect to the direction of travel of the wire or band. The wire or band approaches the loop along a horizontal U-shaped path with the feeding and reversing roll pairs operating on the upper and lower horizontal legs of that path, respectively, and the tensioning means acting downwardly on the wire or band in the bend of its U-shaped path.
