Definitions

  • the invention relates to a method for producing Bristle goods with a bristle holder and bristle trim from individually standing bristles made of plastic.
  • bristle goods are Brushes of all kinds, floor cleaning devices with bristles, Brushes of all kinds, as well as tapes, plates, mats or the like, which are covered with bristles, understood. It can in particular concern body care brushes, such as toothbrushes, Massage brushes, hair brushes or the like. or to Brush for applying coating agents, cosmetics, Drugs or the like or around floor mats, brush tapes, Trade polishing tapes or the like.
  • the bristles are usually in such bristle products combined into bundles or larger packages and in this shape attached to the bristle holder.
  • This type of attachment is complex and leads in some applications, especially with hygiene brushes, to undesirable side effects, because the necessary holes in the bristle holder for the accumulation of dirt and bacteria to lead.
  • bundles of larger diameters or bristle packs like they are necessary for brushes, the bundles or packages were in a putty or glue bed attached. Due to the advent of plastic bristles have other attachment options opened, namely the welding of the bundle with the Carrier or pouring the ends of the bundle into the molten Backing material.
  • the bristle holder usually also forms the handle or handle of the brush in the Usually be rigid and made of an inexpensive plastic consist while the bristles are made of a high quality Plastic with comparatively high wear resistance, good bendability and high fatigue strength must exist. Therefore come for the bristle holder primarily polyolefins, for the bristles themselves in contrast, polyamides in question.
  • Plastic pairings can not or only weld poorly.
  • the bundles must therefore be closed at their ends Thickenings are melted to an additional To generate adhesion in the carrier.
  • bristle products are known in which the bristle stock in addition to bundles of bristles, stand-alone bristles has or completely from such individual bristles consists.
  • EP 0 165 546 A1 describes a toothbrush, their trimmings partly from bundles of bristles, partly from Single bristles exist.
  • the individual bristles are nationwide arranged and - like the bundle by welding attached to the plastic bristle holder. This , as already indicated, sets certain material combinations advance and usually requires for the wearer in Adaptation to the bristles a much too expensive plastic.
  • Such storage spaces are common with brushes realized by deposits or the like (DE 92 06 072 U1, DE 30 25 010 A1), which is within the attachment zone are provided and the bristles in this area laterally oust to immediately following the Insert to create chamber-like free spaces that the Pick up the application medium and when pressing the brush and Release the bristles.
  • These chambers are essential Prerequisite for an even order, such as also sufficient for a brush stroke large area can be covered. This is with plastic bristles especially important because they are against natural bristles poorer holding power for the application medium have. It should also be borne in mind that with all brushes and brushes with which media on one Surface to be transferred, this order media have very different viscosities.
  • the invention has for its object a method propose with the bristle goods with single standing Bristles can be made of plastic at which the bristles have defined and predeterminable distances adapting to the respective order medium and the Show the intended use of the bristle goods.
  • the bristles individually supplied to the manufacturing process, in one such an arrangement to each other that their later positioning within the framework of the bristle trim.
  • the bristles are clamped so that they come out of the Can not shift position radially or axially.
  • at least on the fastening side Surface of the bristle carrier a bed from a prepared liquid, curable material.
  • the the Hole template protruding and immersed in the bed attachment-side ends of the bristles are individually and completely surrounded by the liquid bed material and firmly integrated after the bed has hardened.
  • the individual bristles can be defined Distance from each other and in a predetermined arrangement connect to the bristle holder. It is possible any desired distance of the bristles within the Bristle trim, as well as any desired assignment of Bristles to each other through appropriate perforated templates realize. This ensures that the bristles not tightly packed, but rather defined capillaries created. Each can any capillary shape by assigning the bristles and any capillary cross-section by distance of the bristles. This is an optimal adjustment to the intended use of the thus manufactured Bristle goods possible, in particular the aforementioned geometry also to the respective viscosity adapt the order medium to be processed. For low-viscosity application media, the distance becomes narrower choose than for more viscous media.
  • each bristle Furthermore better use of the properties of each bristle than in a bundle or package arrangement, where the inner bristles supported by the outer bristles are consequently not capable of bending at all can be exploited.
  • they are outside lying bristles more stressed with the result that it also deforms more quickly or is otherwise unusable be off while with a bristle trim individually standing, spaced bristles each bristle their Effect can develop and all bristles essentially are claimed in the same way, so that the life can be increased because it is not early for Failure of individual bristles comes.
  • the bristles are preferably made using the perforated template even immersed in the bed of the liquid material.
  • the bed can also be used the fixed hole template can be moved.
  • the individual bristles can be used as endless monofilaments Hole template fed and drawn into this. After fixing the endless monofilament in the hole template the bristles on the feed side of the hole template can be cut to length from the endless monofilament if desired. The cutting to length can of course only take place after curing of the bed.
  • the endless monofilaments can be used individually or in groups stored on a spool and subtracted from it become. Provided that several monofilaments are stored on one spool they will be fed to the punch template before feeding isolated. Instead, the bristles can also be from longer monofilament sections or also to length processed cut.
  • the invention thus also gives the possibility of bristles made of different material, with different Diameters and / or cross sections (circular, polygonal od. Like.), As well as different surface structure (smooth, roughened, flocked, etc.) easy to process. In particular structured or polygonal bristles bundles are very difficult to process or lead to uncontrolled capillary spaces in the bundle.
  • the invention defines Conditions created.
  • the invention also gives the possibility that within the bristle trimmings bristeless free spaces generated that bristles only in those holes of the Hole template are introduced, which are congruent with Bristle positions in the bristle are.
  • bristle trim with a single hole template with different bristle distances, as long as they in the spacing grid in the hole pattern of the template, to manufacture.
  • the invention also gives the possibility of a Bristle trimmings made of individually standing bristles and in bundles Arrange arranged bristles by the individual Bristles and the bristles combined into bundles at the same time in a perforated template, the perforated pattern of which Positioning the individual bristles and the bristle bundles within the bristle trim, if introduced be that the attachment-side ends of the Single bristles and the bundle on the opposite Extend the side of the hole template. Then it will be the Single bristles and the bundles at the same time in the bed immersed and otherwise proceed as before. To this Bristle goods can be defined differently create effective brush surfaces.
  • the bed on the bristle holder can be a liquid adhesive, a cold or polymerizing at moderate temperature Plastic or from the melted bristle carrier itself or its melted surface formed become. Depending on the material combination of bristle and bed there is a non-positive and / or material bond.
  • the pull-out strength of the individual bristles can still be increased by the fact that the individual bristles after Insertion into the hole template at its protruding, attachment-side ends structured or thermally or mechanically deformed and then in the bed can be immersed, so that in addition a kind Form closure is given.
  • the bristles after insertion into the hole template or in an upstream similar one Hole template clamped and on its the fastening side Cut ends opposite ends flat and then these ends into one of theirs flat cut surface processed different shape, e.g. be rounded. Only then do the bristles come with the attachment-side ends using the hole template immersed in the bed.
  • the Machining the ends of the bristles on the usage side optimally, mechanically, for example by grinding, by chemical treatment or by thermal treatment e.g. using laser beams.
  • the advantages of the spaced arrangement of the individual bristles in a special way Laser processing the bristle ends for the purpose of rounding is true known.
  • the method fails with bundles arranged bristles because the bristle ends within the Bundles have different distances and therefore cannot be controlled exactly with the result that part of the bristles welded together.
  • the bristle ends in the method according to the invention is the control of the bristle ends with the laser source exactly possible.
  • the brush points a handle 1 on his head with a so-called Brush clamp 2 is provided, which is a kind of sleeve forms and the outer outline of the bristle trim of the Brushes determined.
  • a Bed 3 made of a liquid or liquefiable material locked in.
  • the handle 1, the brush clamp 2 and that Bed 3 together form the bristle carrier.
  • the handle 1 of the brush is in the manufacturing plant in positioned in a manner not shown.
  • the bristles 4 stand individually on the bristle carrier to fix.
  • the bristles are the bristles as endless monofilaments 5 from fed to a coil 6.
  • the leading end of the endless monofilament 5 is referred to a total of 7 Hole template inserted and drawn into this.
  • the perforated template is made in several parts. It consists of three congruent template parts 8, 9 and 10 and clamping plates 11, 12 arranged between them which are movable according to the horizontal directional arrows are.
  • the hole template 7 points in all of them Components holes 13, the diameter of which is slightly larger is as the cross section of the individual bristles 4.
  • perforated template 7 has a perforated pattern that is congruent with the positioning and arrangement of the individual bristles 4 is inside the brush bristle trim. This can also be seen in Figure la, where the template part 8 shown broken off and the one below Clamping plate 11 can be seen.
  • the endless monofilaments 5 are with their leading end retracted or inserted into the hole template 7 until the leading ends of the hole template 7 on the opposite Tower over the side. They then form the fastening side Ends 14 of the individual bristles 4.
  • the clamping plate 11 and the clamping plate 12 in the clamping position moved so that the bristles axially and radially are clamped.
  • the hole template 9 with the clamped bristles towards the bristle carrier moves until the fastening-side ends 14 Immerse in the liquid bed 3.
  • diving the front template part 10 and one of the clamping plates into the brush clamp 2 so that it is centering acts while the template part 9 on the free end face the brush clamp 2 is seated and thus the immersion depth the attachment-side ends 14 in bed 3 predetermined.
  • the hole template 7 can of course also on another Position filled with the bristles and with the complete prepared bristle trim in the position according to FIG. 2 be transported. Instead of the perforated template, too the bristle holder against the stationary template be moved.
  • FIG 3 is an embodiment of a brush-like Bristleware shown.
  • 4a shows the bristle carrier 15 recognizable by its surface on the fastening side has the hardening bedding material.
  • the single bristles 16 are arranged and embedded equidistantly, but have, as Figure 3c shows, different lengths so that the bristles also move towards their free ends show different bending behavior and also between the shorter and longer bristle ends Storage spaces are created, like this in particular can be seen from Figure 1c.
  • the bristle ends are therefore in a curved envelope.
  • Figure 4 shows a modified embodiment in which in the longitudinal median plane of the bristle trimmings Holes of the hole template are not loaded or the hole template is closed there, so that inside the bristle trimmings create chamber-like free spaces 18, which can serve as storage space for the order medium.
  • Figure 5 shows a toothbrush with a bristle holder forming brush head 19.
  • the entire bristle trim is formed from individually standing bristles 20 with the same Distance from each other and the surface of the brush head 19 attached to the brush head 19 largely filling are.
  • the ends 21 of the individual bristles 20 are again rounded like a cathedral.
  • the bristle ends are 21 on an envelope surface with a kind of wave profile, being continuous in the transverse direction (perpendicular to the plane of the drawing) Wave valleys and wave peaks emerge.
