Definitions

  • the present invention relates to a method of treatment, and more particularly of filling the medullary canal with natural fibers used in toothbrushes.
  • the natural fibers used for making toothbrushes such as boar or Tchunking pig bristles, have a general appearance that looks like a mini pipe.
  • the object of the present invention is to propose a method for treating the end of the natural fibers, making it possible in particular to obstruct the free end of the medullary canal of these fibers in order to prevent any foreign body from entering it.
  • the process for treating natural fibers used for making toothbrushes consists in applying the free end of the fibers, to a grinding wheel, in a combined movement.
  • This combined movement is composed of a rocking back and forth of the fibers above a grinding wheel on either side of a plane perpendicular to the grinding plane, said grinding wheel being driven in rotation about its axis, arranged parallel to the grinding plane, accompanied simultaneously by a rotation between the grinding wheel and the fibers, about an axis substantially perpendicular to the grinding plane, that is to say the plane tangential to the grinding wheel corresponding to the mean contact plane fiber ends with the surface of the grinding wheel.
  • the rotation between the fibers and the grinding wheel, around an axis substantially perpendicular to the grinding plane, is advantageously carried out around an axis passing through the axis of rotation of the grinding wheel and situated in the plane of the latter.
  • the method consists in applying the fibers a first time on the grinding wheel according to the combined movement previously defined, then in spreading the end of the fibers away from the surface of the grinding wheel, and in reapplying the fibers on it, in the same combined movement.
  • the method consists in applying the end of the fibers to a grinding wheel according to the previously defined combined movement, then in moving and applying the fibers over a second grinding wheel in the same movement combined.
  • the combined movement schematically shown in Figure 1 is composed of a rocking back and forth 14, 14 'of the fibers above the grinding wheel 10 on either side of a plane perpendicular to the grinding plane, said grinding wheel 10 being driven in rotation (N) about its axis 12, parallel to the grinding plane, accompanied simultaneously by a rotation (n) between the grinding wheel 10 and the fibers, substantially in the grinding plane, around an axis 13 substantially perpendicular thereto.
  • the grinding wheel 10 is rotated about its axis 12 according to a movement represented schematically by the arrows referenced N in the figures, using a shaft, partially shown.
  • the rotary drive shaft is, moreover and simultaneously, driven by a relative movement of rotation, with respect to the natural fibers, rotation represented by the arrows references n in the figures, around an axis 13 passing through l 'axis of rotation 12 of the grinding wheel 10 and located in the plane thereof, while being substantially perpendicular to the grinding plane.
  • This second movement (n) causes rotation between the fibers and the grinding wheel 10, substantially in the grinding plane.
  • the end of the fibers is, moreover, applied to the grinding wheel 10 animated by the double movement described above, according to a back and forth movement, between two extreme positions illustrated at 14 and 14 'in FIG. 1; this pendulum movement is carried out on either side of a longitudinal plane perpendicular to the mean plane of the end of the fibers.
  • the fibers thus applied to the grinding wheel can be united by bundles according to any assembly or be previously arranged on the support of a toothbrush.
  • FIG. 2 shows a device used for implementing a variant of the method according to the present invention consisting in applying the ends of the fibers to the grinding wheel 10 for the first time according to the combined movement described above, then moving and apply the fibers over a second grinding wheel 20 in the same combined movement.
  • the device consists of two grinding wheels 10, 20, the drive shafts of which are coplanar.
  • Each of these grinding wheels 10 and 20 is animated by the double movement previously described, respectively represented by arrows N and n.
  • Each grinding wheel rotates at a speed (N) comprised for a grinding wheel of approximately 20 cm in diameter between 1000 and 5000 revolutions per minute, and preferably at a speed of 2000 revolutions per minute, or at a tangential speed comprised between 1250 m by minute and 6250 m per minute while the rotation of each drive shaft of the grinding wheels around the axes 13 and 23 which are perpendicular to them is carried out at a speed (n) of between 50 and 250 revolutions per minute and preferably at a speed of 120 revolutions per minute.
  • N a speed comprised for a grinding wheel of approximately 20 cm in diameter between 1000 and 5000 revolutions per minute, and preferably at a speed of 2000 revolutions per minute, or at a tangential speed comprised between 1250 m by minute and 6250 m per minute while the rotation of each drive shaft of the grinding wheels around the axes 13 and 23 which are perpendicular to them is carried out at a speed (n) of between 50 and 250 revolutions per minute and preferably at a speed of
  • the method of treatment and obturation of the medullary canal of each fiber then consists, firstly, in applying the end of the fibers to the grinding wheel 10 in a pendulum movement between two extreme positions 14 and 14 ′, then in moving in a second step the fibers above the second grinding wheel 20 and to apply thereto, in a third step, the end of these in a pendulum movement between two extreme positions 24 and 24 ', the toothbrush then being removed from the grinding station, as shown by the reference arrow A in FIG. 2.
  • the duration of a rocking back and forth of the fibers above each grinding wheel corresponds substantially to the duration of a complete rotation between the fibers and the grinding wheel, in the grinding plane.
  • each of the three times previously defined may last approximately half a second.
  • the process which is the subject of the present invention is well suited to all fiber diameters, whether these are extra hard, hard, medium or flexible.
  • the implementation of the process causes friction which, without burning the keratin, causes it to penetrate into micro-particles in the medullary canal.
  • a phenomenon of torsion printed at the end of the fibers this phenomenon changes the texture of the fibers which tends to tighten and makes the fibers more resistant to brushing.
  • the implementation of the method on the other hand has the advantage of properly rounding the end of the fibers and thereby making them non-aggressive for the gums.
  • the present invention is not limited to the embodiment which has just been described, from which other forms and other embodiments may be provided, without thereby departing from the scope of the invention , it is possible, for example, to obtain a rotation between the fibers and the grinding wheel, in the grinding plane, by rotation of said fibers and no longer of the grinding wheel.
