Abstract:
Tool for binding a belt around an object, which tool contains a tightening device (8) for performing a tightening operation on the belt (5) which is resistant to bending, which device comprises a tightening roller (10), which is provided with teeth, said tightening roller is continuously driven during the tightening operation and, on reaching a predetermined belt tension, continues to rotate with respect to the belt (5), and an abutment, which supports the belt (5) on the side opposite the tightening roller, characterized in that the abutment includes at least two support rollers (11) which are arranged at an angular spacing of 30.degree. to 70.degree. on the circumference of the tightening roller (10) and are clamped onto the tightening roller (10) by spring force (14), and the diameter of the tightening roller (10) and the distance between the support rollers in relation to the resistance to bending of the belt (5) are selected in such a way that the force acting per unit length between the belt (5) and the circumference of the tightening roller (10) is approximately the same at the support rollers as between the support rollers.
