However, it also results in a frictional force of the coil wire at the outlet of the wire guide tube, which adds to the determined by the wire tension regulator traction. If an exit angle of the coil wire from the wire guide tube with respect to its longitudinal axis known, it can be determined by a trigonometric calculation of this angle and the measured radial component of the force acting on the wire guide tube force acting on the coil wire after the outlet of the wire guide tube tensile force.
