  • Stripping flat cables
    Patent number: 7045739
    Abstract: The invention pertains to a process for stripping conductor traces (2) of extruded or laminated flat cables (1), so-called FFCs, using laser beams (4). The invention is characterized in that a beam of a CO2 laser or an Nd:YAG laser (4) is used in a first step, and an excimer laser or a frequency-multiplied Nd:YAG laser is used in a second step, in that the CO2 laser or Nd:YAG laser is allowed to act on the extrudate (3) of FFC (1) with an intensity and duration such that an extrudate layer (6) a few microns thick still remains in the area of the conductor trace(s) (2), said layer being removed in the second step by the beam of the excimer laser or frequency-multiplied Nd:YAG laser.

  • Stripping insulation from flat cables
    Patent number: 7026572
    Abstract: A method for stripping insulation from a region, a so-called window, of a flat cable, a so-called FFC, by means of a laser. The laser used to form the window, preferably a CO2 laser, operates only in the edge region of the window, and in a subsequent step the remaining insulation in the interior of the window is removed. This remaining insulation is preferably removed by means of a type of doctor blade or a brush.

  • Stripping of FFCs
    Patent number: 6936788
    Abstract: A method for stripping flat cables, so-called FFCs, particularly for extruded FFCs, by using laser beams and devices for performing the method. Two coaxial laser sources pointing toward each other are used for removing the extruded material, the flat cable being located essentially in the plane of symmetry between the two laser sources, and the two laser sources being activated in an alternating manner. Preferably, a laser beam-impervious cover is arranged between the flat cable and the inactive laser source at least during the activation of one of the laser sources.
