Definitions

  • the invention relates to a method for producing a bristle field of a toothbrush formed from a plurality of folded bristle bundles made of plastic bristles, in which the bristle bundle is first separated from a bristle pack with a predetermined length of the bristles, folded by means of a flat plunger and an anchor and successively into blind holes through these of the bristle field of the toothbrush are pressed in and firmly anchored there.
  • toothbrushes have required for dental reasons that they should ensure, in addition to optimal cleaning of the teeth, gentle treatment of the gums.
  • the bristles made of plastic must not have any sharp edges, fissures or the like at their free ends on the use side, since this can lead to injury to the gums.
  • the typical feature of a high quality toothbrush is that the ends of the individual bristles are rounded. This prevents injury to the gums and the desired massaging effect of the rounded bristle ends comes into its own on the gums.
  • the ends of the bristles on the usage side are preferably rounded off by a type of grinding process, it should always be ensured that all bristles of a bundle or an entire bristle field are rounded evenly.
  • the bristle bundles having a greater length are first all cut to the same length and only then are the free bristle ends rounded off.
  • the individual bristles of a bristle bundle are rounded off at the ends on the usage side before they are inserted into the toothbrush.
  • the aim today is that the individual bristle bundles and / or the individual bristles in the bristle bundles have a different length. This should increase the cleaning effect and improve the massage effect, especially in the critical interdental spaces.
  • High / low cuts that can run lengthways or crossways, wave cuts, V cuts and saw cuts are known.
  • This different length of the bristles can be easily achieved in the process in which the individual bristle bundles are cut off from an endless bristle strand, rounded on the usage side and then, if necessary after a fusion of the fastening-side ends, inserted or poured into a toothbrush.
  • the lower-lying bristle ends are either not or only insufficiently grasped by the processing tool, so that the lower-lying bristle ends can still have sharp edges, fissures or the like. This means that in this manufacturing process, the desired quality of a high-quality toothbrush - the individual bristle ends are optimally rounded - cannot be achieved through the profiled cut when cutting the bristles or bundles of bristles of a bristle field. It should also be taken into account that when rounding off the bristle ends of a bristle field of a toothbrush, dust is produced which can become lodged in the bristle field and which can no longer be completely removed even with great effort.
  • the invention is therefore based on the object of disclosing a method for producing a bristle field of a toothbrush formed from a plurality of folded bristle bundles made of plastic bristles, in which, even with conventional production of the bristle field - separation, folding and fastening of the bristle bundles by means of an anchor - when the bristle field is profiled with different bristle lengths an optimal rounding of the Bristle ends is possible.
  • bristle bundle 1 of the drawing shows the free end region of a bristle bundle 1, which consists of a plurality of bristles 2 made of plastic.
  • bristle bundle 1 For better clarity of the bristle bundle 1, only eight bristles 2 are drawn on a much larger scale.
  • the bristle bundle 1 was now produced in a manner known per se in such a way that bundles with the same number of bristles 2 are separated from a bristle pack, the number of bristles 2 of these bundles being exactly half of the bristles 2 of the finished bundle 1.
  • the length of the individual bristles 2 of the bristle pack corresponds to a precisely specified length.
  • all bristles 2 of the bristle pack are optimally rounded at both ends, this rounding being carried out either at the manufacturer of the bristle pack or when dressing the bristle packs. This rounding of the ends of the bristles 2 can take place either in the entire bristle pack or in individual bundles. It is advantageous if the brushes of a bristle bundle are rounded off on the way from the separation from the bristle bundle to the corresponding blind hole.
  • the isolated bundles of bristles are then folded using an anchor made of metal, so that the finished bundles 1 are formed. These finished bundles 1 are then pressed or stuffed over the anchor into blind holes in the bristle field of the toothbrush, the respective bristle bundle 1 being firmly secured in the respective blind hole by the metallic anchor. Conventional bristle machines can therefore be used to produce the bristle field of the toothbrush.
  • the ends of the bristles 2 are not necessarily in one plane, as can be seen particularly clearly in FIG. 1.
  • the deviation of the individual bristle ends from an imaginary plane can be between 0.5 and 2.0 mm.
  • FIG. 2 shows six bristle bundles 1, 1 a, preferably lying one behind the other in one plane, which corresponds in part to the longitudinal section through the bristle field of a toothbrush.
  • the two inner, shorter bristle bundles 1 correspond to the bristle bundle 1 of FIG. 1, in which the aim is for the ends of all bristles 2 to be in one plane if possible.
  • the two outer and the two middle bristle bundles 1 a which originate from another bristle pack with a larger bristle length, have an outwardly or inwardly rising contour of the individual bristles 2.
  • This contour can be achieved in a simple manner in that the bundles formed by individualization and forming the individual bristle bundles 1 a are folded slightly outside the center with a plurality of bristles. This folding depends on the position of the bristle bundle 1a in the bristle field either above or below the center of the bristle bundle 1a.
  • the ends of the individual bristles 2 can deviate by a measure of approximately 0.5 to 2.0 mm from a predetermined level or a predetermined profile, which may be desirable for the massage and cleaning effect sought.
