  • This angle formed by the convergent branches of the single cutting wire F around the respective tension pulley has thus a limited width, with the result that to short displacements of the tension pulley 117 or 119 in the direction D corresponds a significant change in the length of the cutting wire and therefore in the cutting wire tension.
  • the beam 129 is stationary with respect to the frame 105 and may be integral with it. This allows a significantly simpler structure of the machine.

As it is shown in the diagram of figure 2, for instance, the diameter of the tension pulleys 117, 119 may be nearly the same as that of the idle guide drum 111. A greater diameter of the tension pulleys reduces the shear stress of the cutting wire due to bending in the guide area.
  • the beam 129 is not fixed with respect to the frame 105, and is provided with a pre-tensioning movement according to the double arrow fl29.
