Definitions

  • the invention relates to a method for producing bristle fields for brushes, tufts of plastic bristles inserted into perforations in a holding plate and the ends facing away from their later free working ends fused together and thereby fixed to the holding plate.
  • the invention further relates to a device for producing bristle fields for brushes with a holding plate and this opposite protruding tufts of plastic bristles.
  • the invention relates to a bristle field with a holding plate and this opposite protruding tufts of plastic bristles for a brush, produced according to the aforementioned method and / or by means of the aforementioned device.
  • a method of the type mentioned at the outset, a device for carrying it out and a corresponding bristle field for brushes, in particular for toothbrushes, is known from EP-B-0 405 204 and has proven itself.
  • bristle fields can be formed in a simple and rational manner from individual bristles and tufts of bristles, in which the tufts of bristles and the bristle field can have any geometrical arrangements of the free working ends of the individual bristles and the attachment to a holding plate avoids anchoring with anchor plates.
  • the holding plate allows the formation of interchangeably attachable bristle fields on a brush body, which promotes hygiene in toothbrushes without causing too much waste, because the brush bodies with a handle can be reused several times.
  • the invention is therefore based on the object of providing a method and a device of the type mentioned at the outset, which makes it possible to manufacture the holding plate and the plastic bristles from different materials and to select a different material for the material of the holding plate than for the bristles, for example, a cheaper material or a material with more favorable properties for a holding plate. Furthermore, there is the task of creating a bristle field of the type mentioned at the beginning, in which the plastic bristles and the holding plate can consist of different materials.
  • the holding plate provided with bristles can be inserted into an injection mold in order to attach a handle or other fastening elements by injection molding.
  • a holding plate according to FIG. 8 of EP-B-0 405 204 equipped with the bristles in accordance with the invention could be inserted into an already manufactured brush body with a handle or handle and fastened there, which is also an exchangeable holding plate, for example according to DE B-19600767 or act according to DE-U-91 09 625.
  • the holding plate is part of the brush body from the outset, roughly analogously to the embodiment according to FIG. 9 of EP-B-0 405204, that is to say it forms it and itself has a handle or handle.
  • a particularly expedient embodiment of the method according to the invention can consist in the fact that a holding plate with perforations for the tufts of bristles is produced by the injection molding process, with projections, in particular pin-like, strip-shaped, cross-sectionally polygonal and / or cross-section on intermediate webs and spaces between the perforations or annular projections, with circular or polygonal shape, and these Protrusions are then compressed, in particular under the action of heat, so that a head exceeding their cross-section, a widening or the like protrusion is formed at its end facing away from the holding plate.
  • a holding plate can be made from practically any material, in particular plastic, in which suitable projections are arranged adjacent to the perforations and can be provided with the desired undercuts by upsetting.
  • the cross section of the projections is chosen to have a smaller dimension than the spacing of the perforations in the holding plate. This results in an undercut which is effective in both directions between the heads or the like widenings formed by the upsetting and the top of the perforated edges, so that bristles can be fixed both in the pressure and in the pulling direction by their fusion and the filling of this undercut.
  • the holding plate with its projections can be injection molded from a plastic that has a higher melting temperature than the plastic of the plastic bristles. This makes it possible to choose a correspondingly resistant and possibly also inexpensive plastic for the holding plate, in which the undercuts can be created by upsetting correspondingly dimensioned projections without these being caused by the simultaneous or subsequent fusion of the plastic bristles protruding into the area of the undercuts are melted and possibly destroyed.
  • the invention also allows the holding plate to be made of metal or sheet metal, for example punched out, and for the perforations to be pressed in from the side on which the bristles protrude in the use position such that the perforation edges protrude at the top and at least in some areas away from the respective perforation, forming an undercut. If necessary, it can already be ensured when the perforations are pushed through that the sheet metal parts bent up onto the top of such a metal holding plate bend in such a way that the desired undercut is created from the outset.
  • a preferred procedure, especially when the holding plate is manufactured from a plastic, can be that the bristle tufts are first introduced and filled into the perforations of the holding plate - for example according to EP-B-0 405 204 B1 or also according to EP-B-0 346 646 or in another way - that then the protrusions protruding from the top of the holding plate are melted and / or compressed by the action of heat and at the same time or thereafter the protruding ends of the protruding protrusions from the upper side of the holding plate and the protruding protrusions or at least up to the area of these protrusions Bristles are melted.
  • This enables production in a continuous process in which the individual process steps can be carried out one after the other, one or more heating stations for melting first being able to pass through the projections and then the bristles.
  • a favorable simplification of the method can be achieved in that the projections and the protrusion of the bristles protruding into their area are simultaneously heated or melted at the same time.
  • the projections can be compressed and the bristles can be practically simultaneously positively connected to the undercuts thereby formed, so that in this way two process steps can be carried out simultaneously or essentially simultaneously.
  • the device mentioned at the outset is characterized in that the object is characterized in that it has at least one heating element for melting the projecting ends of the bristles located on the upper side of the holding plate and / or the projections arranged on the upper side, that a holder or tensioning device for the holding plate is provided and that an infeed device for a relative movement between the heating element and the holder for the holding plate for carrying out a pressing movement is provided.
  • the holding plate provided with the initially unattached bristles can be brought into the area of the heating element where the bristles protruding from the upper side of the holding plate can be fused together so that they can fill in undercuts previously arranged or melted at the same time.
  • At least two work stations with heating elements are provided and at least one heating element equipped with projections is arranged in a first work station, the projections of which are movable relative to the projections of the holding plate and can be pressed against the end faces thereof, and if at least in the second work station a further heating element for loading and melting the protruding bristle ends is provided.
  • a heating element can be matched to the melting temperature of the holding plate, which also has a corresponding shape in order to be able to melt and / or to compress the projections provided on the holding plate in a suitable manner to form heads, protrusions or widenings.
  • the heating element of this first work station can be designed so that it does not touch the ends of the bristles that protrude from the holding plate and does not impair them. These can then be melted in the second work station so that they can fill in the undercuts previously formed and / or enclose the heads or widenings.
  • the protrusions on the one hand and the protrusions of the bristles on the other hand can also be melted at the same time, even if the melting temperatures of the materials differ somewhat, because a higher-melting material of the projections of the holding plate with the melting temperature for the bristles at least so far can be softened that it can be compressed to form the undercuts.
  • a bristle field according to the invention produced by the above-described method and / or with the above-described device with a holding plate and this in relation to protruding tufts of plastic bristles for a brush is characterized in accordance with the invention in that the holding plate on its upper side facing away from the protruding bristles has protrusions with undercuts and has these forming widenings and cross-sectional reductions located underneath, and that the holding ends of the plastic bristles which pass through the holding plate are fused together in the region of the undercuts in such a way that the fused part of the tufts of bristles completely overlaps the undercuts or partially and fills the spaces between the bristles and between the bristles and the edges of the perforations.
  • positive locking between the bristles or tufts of bristles and the holding plate and tightness at the passage of the bristles through the holding plate is effected at the same time.
  • the melted ends of the tufts of plastic bristles can enclose the projections provided with undercuts and widenings in the area of the undercuts and projections, and the widenings can be embedded in the fused part of the bristle tufts. This results in a particularly intimate connection of the bristles to the holding plate, although the materials thereof are not fused together.
  • the holding plate can thus even be formed from metal, punched or possibly also injection-molded.
  • a bristle field with a holding plate made of metal or sheet metal with perforations for receiving the tufts or bundles of bristles can, according to the invention, be characterized in that the perforations are pressed in and pierced from the side on which the bristles protrude with their working ends, and in that way form undercuts on the top of the holding plate shaped perforation edges for receiving the melt of the melted plastic bristles and are wholly or partially enclosed by this melt.
  • the protruding bristle ends are fused and, with the possibly jagged, serrated and curved edges of the perforations in the metal plate, solidify in the solidified state with a simultaneous seal in the perforation area.
  • the seal not only has the advantage of preventing the ingress of moisture during later use, but also enables subsequent encapsulation even with high injection pressure without injection molding compound being able to flow through the brush element in such a further production.

However, it is also conceivable and possible to provide different areas of the upper side 8 of the holding plate 1 with different projections 9.
  • these projections 9 can be pin-shaped, strip-shaped, cross-shaped in cross-section or polygonal or even ring-shaped, such a ring not only being circular but also polygonal.

It can be seen above all in FIG. 4 that s ch forms the desired undercut 10 already mentioned between the top 8 of the holding plate 1 located directly at the level of the perforations 2 and these widenings 11.
  • This undercut is not only provided between the widening 11 and the projection 9, which could be sufficient under certain circumstances, because as a result the bristles 4 are positively fixed after their fusion in one direction, which extends from their working ends 6 to their opposite and fused ends 7 is directed, but the undercut 10 is also formed opposite the starting point of these projections 9, because the projections 9 are chosen with a smaller dimension than the distance between the perforations 2 of the holding plate 1 which are adjacent in FIGS. 3 and 4.
