Abstract

The roller which is fixed over the balance axis, has a peripheral flat surface and is provided with a matt nickel coating. The end of the spiral spring is secured to the flat surface by laser welding it at two points, lying adjacent one another along a line at an angle to the end of the spring. The laser welding is carried out using two synchronised laser sources, or by using one source with means for dividing the laser beam into two so as to provide the two welding beams. The roller has an axial slit through it at the opposite side to the flat surface, providing the roller with enough give to allow it to be located over the balance axis.
