Abstract: A roller hemming tool having a main hollow body including a first end for fastening to a robot and a second end having a secondary body which, in turn, includes at least one roller. The tool also includes the following elements which are axially distributed therein: a load cell on the first end; a die in contact with the load cell; a first cylinder in contact with the die; a second cylinder to which the secondary body is fastened; an elastic means in contact with the first cylinder and the second cylinder; and a cap limiting the axial movement of the second cylinder. When in use, the roller continuously exerts pressure in an axial direction, said pressure being successively transmitted to the secondary body, the second cylinder, the elastic means, the first cylinder, the die and up to the load cell.
