ABSTRACT:
A method of elongating and relaxing a stud having an axis and arranged in an object, includes the steps of connecting a stud with a first part which is movable only in an axial direction so as to pull the stud in the axial direction to elongate the stud and thereby to tension it in the object or to relax the stud, and moving the first part only in the axial direction by connecting the first part with a second part which is movable in a transverse direction, cooperating a friction element with at least one of the parts so as to change friction between the parts so that one of the parts has a higher friction than another of the parts and so that the second part is not connected with the friction element but instead is freely turnable relative to the friction element while freely abutting against the latter, and applying a force to at least one of the parts whereby the second part is moved in the transverse direction and the first part is moved only in the axial direction to move the stud in the axial direction so as to elongate the stud.
