Definitions

  • the invention relates to a method for connecting bristle bundles to a plastic bristle carrier, by melting the bristles of each bundle at their fastening-side ends to form a thickening, providing the bristle carrier with holes on the bristle receiving side and / or at least in the thickening receiving areas is melted, the bristle bundle with the thickening is pressed into the holes or in the melted areas of the bristle carrier with thermal deformation, and then the mass rising as it is pressed in is reshaped.
  • bristle bundles are connected to bristle carriers, both of which are made of plastic.
  • the bristle bundle is provided with a thickening, inserted into prepared holes on the bristle carrier and one of the two joining partners is connected to it by melting or hot forming, and the solid connection when the melt solidifies or is molecular Reorientation of the thermoformed areas is obtained.
  • Connecting bristles and bristle carriers made of the same or different plastics in the molten state is a kind of thermal joining process. It is known (EP-A-149 996) to melt the bristle ends into a thickening and to form the bristle bundle into preformed holes on the bristle carrier while the thickening is still plastic. The plastic thickening should fill the holes with undercuts. The irregularities on the surface caused by the ascending melt should be remedied, among other things, by initially forming the holes without undercuts, introducing the thickenings into the holes and then molding the surrounding material onto the thickenings.
  • the bristle carrier has ring-like elevations in the region of the holes, which are then molded on by plasticizing the bristle carrier material.
  • the flatness or unevenness of the bristle carrier surface in turn largely depends on the behavior of the melt in the holes.
  • the bristles are fused together within the bundle at their fastening-side end to form a thickened portion, and in a preferably solidified state these are pressed into the bristle carrier, which in turn is melted locally, for example in the form of holes, until the melt of the bristle carrier flows together again behind the thickening due to molecular reorientation.
  • the melt rises and forms a bead of melt which is then leveled by a smoothing or post-forming tool or to a concrete Er elevation is formed.
  • this method too cannot be completely satisfactory.
  • the invention has for its object to improve the method mentioned in such a way that a flawless, flat surface on the bristle carrier is obtained while ensuring a firm integration of the bristle bundles in the bristle carrier.
  • This object is achieved in that the space above the bristle receiving side and between the bristle bundles is sealed in a ring surrounding the bristle field formed by them against the bristle carrier, and that the mass rising when the bristle bundles are pressed in is displaced and compressed to fill the sealed space using pressure .
  • the space immediately above the bristle carrier between the bristle bundles on the one hand and the bristle carrier outside the bristle field on the other hand is sealed and the mass that has risen between the bristle bundles used, e.g. the melt during a molten work or the thermo-elastically displaced mass during hot forming, displaced into this defined space and at the same time compressed.
  • the mass that has risen between the bristle bundles used e.g. the melt during a molten work or the thermo-elastically displaced mass during hot forming
  • the space is preferably elastically sealed at the edge.
  • the measure serves the same purpose in that the pressure which displaces and compresses the rising mass is applied elastically.
  • Sealing the bristle field and displacing the rising mass with simultaneous compression can take place immediately after the joining process and the plasticity or thermoelasticity still present can be used for the forming process.
  • the plasticity or thermoelasticity still present can be used for the forming process.
  • the bristle carrier on the bristle receiving side is provided with a depression which extends over the entire bristle field and into which the ascended mass is displaced when the pressure is applied.
  • the depression provided on the bristle receiving side and extending over the entire bristle field which can also be partially interrupted by elevations, for example in the area of the bristle bundle, is also able to absorb a larger melt mass without causing a contour change on the bristle carrier surface to lead.
  • the extent of the deepening can depend on the specific application, e.g. The size or extension of the melting pool or pools, the melt volume displaced by the thickening or the bristle bundles, etc., are adapted.
  • the bristle carrier on the bristle receiving side is provided with elevations surrounding the holes or a part thereof, that the elevations are melted at least to a certain depth and are ring-shaped together with the rising mass in the outside of the elevations sealed space is displaced.
  • cross-sections and height-defined elevations are provided on the bristle receiving side, which are completely or partially leveled during the subsequent compression process.
  • a further variant of the method is provided in that the bristle carrier is provided with individual small depressions next to the holes receiving the bundle, which serve as deforming displacement spaces when the bristle bundles are pressed in and the rising mass is displaced.
  • the additional depressions create free displacement spaces into which the mass displaced during leveling and compaction can escape.
  • the depressions can be designed as holes with a small diameter, which are closed and deformed, in particular reduced, when the holes for the bundles are thermally formed and / or when the ascending melt is leveled.
  • the holes receiving the bundles in the bristle carrier are provided with a profile which is formed, for example, from webs, ribs or the like and which is leveled when the hole walls are melted.
  • This embodiment also offers the possibility of not only minimizing the melting mass, but also re, by melting the profile and the near-surface hole wall fix producible.
  • the ribs, webs should be thin-walled, so that they melt and collapse even with a small amount of heat, without the surrounding material of the bristle carrier being melted.
  • the cause of the irregularities in the formation of the melt should be, among other things, that in the known clamping method, in which all bundles of bristles are acted upon by a single clamping plate, different clamping forces are present on the individual bundles of bristles, with the result that individual bundles yield more during the joining process or retreat than others.
  • the cause is to be assumed in different bundle cross-sections and different bristle packs within the bundle due to the inevitable diameter tolerances in the bristle monofilaments.
  • each bristle bundle by fluid pressure or spring force provided according to the invention, it is ensured that an equal clamping force acts on each bristle bundle regardless of cross-section and bristle pack, with the result that none of the bristle bundles or individual bristles within a bundle can move backwards.
  • This ensures that the bristle protrusion above the guide plate when melting the bristle ends is always the same and also ensures during the joining process that all bristle bundles are inserted into the melt on the bristle carrier with the same pressure or the same immersion depth due to the lack of possibility of evasion. This in turn minimizes the melt rising during the joining process, on the other hand it is evened out during successive joining processes.
  • the aforementioned negative effect can also be largely eliminated by clamping the bundles of bristles between the spaced-apart guide plates under the action of a plate-parallel clamping force acting in the intermediate space according to the principle of rope friction.
  • the inventive deflection of the bristle bundle according to the principle of rope friction can exert such a clamping force that the frictional forces between the bristles of a bundle to prevent individual bristles from evading.
  • the invention is based on a known device (for example EP 0 149 996) which has a receptacle for the bristle carrier, at least two guide plates arranged at a distance from one another and parallel to one another with aligned channels with aligned channels for feeding the bristle bundles, at least one Bristle bundle at least during the connection to the bristle carrier in the channels fixing clamping device and at least one of the bristle protruding beyond the channels and the bristle body on the bristle receiving side melting device.
  • a known device for example EP 0 149 996 which has a receptacle for the bristle carrier, at least two guide plates arranged at a distance from one another and parallel to one another with aligned channels with aligned channels for feeding the bristle bundles, at least one Bristle bundle at least during the connection to the bristle carrier in the channels fixing clamping device and at least one of the bristle protruding beyond the channels and the bristle body on the bristle receiving side
  • Such a known device is characterized according to the invention in that the guide plate facing the receptacle or a form plate placed in front of it has a sealing zone which surrounds the bristle field in an annular manner and which has a corresponding annular sealing zone on the bristle carrier or on its receptacle when the guide plate or the form plate is moved together and the recording interacts.
  • the sealing zone becomes effective when the bristle carrier receptacle and guide plate or mold plate are moved together and forms a closed space above the bristle side, enclosing the bristle field, into which the melt that has risen during the joining process is displaced during further moving together.
  • the annular sealing zone is formed by a groove and a rib engaging in it, one of which on the guide or molded plate, the other is arranged on the bristle carrier or on its holder.
  • the annular sealing zone can be formed by interlocking steps on the guide or form plate on the one hand and on the bristle carrier or its receptacle on the other hand.

  • the sealing itself can again take place via a step or the like, while the forming pressure when the melt is displaced always remains the same even with different melt volumes due to the elasticity of the pressure surface, or the available space automatically adjusts to the volume of the mass to be displaced adjusts.
  • the guide plate or the molding plate can be heated in order to ensure a constant viscosity in the area to be formed.
  • a further embodiment of the device according to the invention is characterized in that at least one of the guide plates has a cavity or a cavity is formed between two adjacent guide plates, and that channels which pass through the cavity are provided for guiding the bundles of bristles, the walls of which are wholly or partly under the action of a Fluid pressure in the cavity against the bristle bundles are deformable.
