  • the marking stick 5 could be transparent and manufactured from polycarbonate.
  • the holder 3 may be displaced in the longitudinal direction of the metal strip 1, this stepless displacement being indicated by the arrows Pl and P2. Since the holder 3 is equipped with a magnetic mat 4 the holder 3 may be placed in an arbitrary position on the metal strip 1.
  • the marking stick 5 is displaceable in its longitudinal direction relative to the holder 3. This is indicated by the double arrow P3 in figures 1 and 3.
  • the magnetic force of the magnetic mat 4 must be of such power that it fixes the position of the holder 3 relative to the metal strip 1, even if the marking stick 5 is displaced at its maximum relative to the holder 3, i.e. the holder 3 engages one end of the marking stick 5.
  • FIG 3 further movement possibilities for the holder 3 relative to the metal strip 1 is shown. It is thus indicated in figure 3, by means of the double arrows P4 and P5, that the holder 3 may be rotated relative to the metal strip 1. If the holder 3 is given such a rotation of a half revolution, from the position shown in figure 1, the ends of the marking stick 5 will exchange places. In such a case “Dx" has assumed the position of "Sin” without ceasing the engagement between the holder 3 and the marking stick 5.
