DETAILED DESCRIPTION

[0077] FIGS. 1 and 6 to 13 and 16 to 20 show at least parts of a bristle product manufacturing machine which as an entity is denoted with the reference sign 1 and which is specified for carrying out the method for manufacturing bristle products 2, explained hereunder. Individual steps of the method are shown in FIGS. 6 to 13. FIGS. 2 to 5 visualize a method of the prior art, in which bristle bundles 5 are fastened in bristle carriers 3 by means of fastening anchors 6 of metal.

[0078] In the method which makes use of the invention, a bristle carrier 3 of a bristle product 2 to be manufactured is provided, said bristle carrier 3 having at least one bundle receptacle bore 4. Subsequently, a bristle bundle 5 is incorporated, specifically pushed, conjointly with a fastening anchor 6 into the bundle receptacle bore 4 and anchored therein by means of the fastening anchor 6. During incorporation into the bundle receptacle bore 4, the fastening anchor 6 is plastically deformed while forming at least one end-proximal anchoring structure 7.

[0079] The fastening anchors 6 shown in FIGS. 6 to 13 have two end-proximal anchoring structures 7 which have been generated by a plastic deformation of the fastening anchor 6.

[0080] The anchoring structures 7 are created when incorporating the respective fastening anchor 6 into the bundle receptacle bore 4, due to contact between the fastening anchor 6 and a bore wall 8 of the bundle receptacle bore 4. The end-proximal anchoring structures 7 are end-proximal thickenings. In this way, the fastening anchor 6 which has been plastically deformed during incorporation into the bundle receptacle bore 4 obtains the approximately bone-shaped design shown, for example, in the righthand bundle receptacle bores 4 of the bristle carriers 3 of FIGS. 9 and 13.

[0081] In the exemplary embodiments of the method shown in FIGS. 6 to 13, the fastening anchors 6 are symmetrically deformed. Depending on the embodiment of the method, it is also possible for the fastening anchors 6 to be asymmetrically deformed during incorporation into the bundle receptacle bores 4.

[0082] Upon incorporation of the fastening anchors 6, the fastening anchors 6 can also be compressed in their respective bundle receptacle bore 4. This can take place, for example, by means of a thruster tongue 9, likewise shown in the Figures, of a stuffing tool 10 of the bristle product manufacturing machine 1. The fastening anchors 6 are also incorporated into the bundle receptacle bores 4 conjointly with the bristle bundles 5 by the thruster tongue 9. Upon incorporation into the bundle receptacle bores 4, the fastening anchors 6 can be compressed and, as a result, a filling level of the bristle bundle 5 placed in the respective bundle receptacle bore 4 can be increased. A filling level of at least 65% or else of at least 72% can be achieved in the process. Furthermore, the fastening anchors 6 upon incorporation into the respective bundle receptacle bore 4 can also be compressed and, as a result, an extraction force of the bristle bundle 5 fixed by the respective fastening anchor 6 can be increased. The extraction force of the bristle bundle 5 herein is the force that has to be applied in order to extract the bristle bundle 5 from the receptacle bore 4 counter to the retaining force of the fastening anchor 6.

[0083] In the variant of the method shown in FIGS. 10 to 13, it is moreover provided that, during incorporation of the fastening anchor 6 into the bundle receptacle bore 4, material of the bristle carrier 3 from a peripheral region of the bundle receptacle bore 4 is displaced into the bundle receptacle bore 4 and in the process is displaced over the fastening anchor 6 placed in the bundle receptacle bore 4 by the already mentioned thruster tongue 9 of the stuffing tool 10 of the bristle product manufacturing machine 1. In the process, the displaced material 19 makes its way over the anchoring structures 7 of the fastening anchor 6, as can be particularly readily seen by means of FIGS. 12 and 13, for example.

[0084] The fastening anchor 6 and the bristle carrier 3 during incorporation of the fastening anchor 6 into the bundle receptacle bore 4 are connected to one another in a materially integral manner, in particular adhesively bonded and/or welded to one another. To this end, it is advantageous when the fastening anchors 6 and the bristle carriers 3 are composed of correspondingly compatible materials which enable a materially integral connection between the fastening anchors 6 and the bristle carriers 3. In order to facilitate the materially integral connection between the bristle carriers 3 and the fastening anchors 6, the respective bristle carrier 3 can be heated prior to and/or upon incorporation of the fastening anchor 6.

[0085] It is highlighted in particular by the top views of a bristle carrier 3, or else by the perspective illustrations of a bristle carrier 3 according to FIGS. 9 and 13, that a length of the respective fastening anchor 6 is larger than a diameter of the respective bundle receptacle bore 4. This facilitates the plastic deformation of the fastening anchors 6 while forming the anchoring structures 7 during incorporation of the fastening anchors 6 into the bundle receptacle bores 4.

[0086] In the method visualized in FIGS. 10 to 13, the fastening anchors 6 are incorporated into the respective bundle receptacle bore 4 by a thruster tongue 9 which on its front end 12 has a width larger than a diameter of the bundle receptacle bore 4 in the bristle carrier 3. This makes it possible that, during incorporation of the fastening anchors 6 into the bundle receptacle bores 4, material from the peripheral region of the bundle receptacle bores is peeled by the thruster tongue 9 and displaced into the bundle receptacle bores 4 so as to in the latter also fix the fastening anchors 6 in a form-fitting manner. The width of the thruster tongue 9 corresponds to a spacing between two narrow sides of a front end 12 of the thruster tongue 9.

[0087] The fastening anchors 6 and the bristle carriers 3 used when carrying out the method are composed of plastics material and preferably have at least some content of recycled plastics material. The fastening anchors 6 are composed of a plastics material which, depending on the specific application, can be softer or harder than a plastics material of which the used bristle carriers 3 are composed. It is advantageous when the fastening anchors 6 and the bristle carriers 3 are composed of materials from the same plastics material family, or even of the same plastics material. This can facilitate a materially integral connection between the fastening anchors 6 and the bristle carriers 3, as has been described above.

[0088] The plastics material of which the fastening anchors 6 and the bristle carriers 3 are composed, can have the hardnesses of at least 60 Shore D to 80 Shore D or 100 Shore D, or optionally even more, as mentioned earlier.

[0089] The plastics material of the fastening anchors 6 and/or of the bristle carriers 3 can have, for example, an E modulus of at least 1000 MPa or of at least 2000 MPa, in particular an E modulus between 1000 MPa and 2000 MPa and 10,000 MPa. The respective plastics material can have a tensile strength of, for example, at least 30 MPa or of at least 45 MPa, preferably a tensile strength between 30 MPa or 45 MPa and 110 MPa.

[0090] For example, polyamide 12 (PA12), polyamide 6 (PA6), polyamide 6.12(PA6.12), polystyrene (PS), polybutylene terephthalate (PBT), polycarbonate (PC), polyoxymethylene (POM), styrene acrylonitrile resin (SAN), acrylonitrile, polyethylene terephthalate (PET), or polypropylene (PP), in particular fiber-reinforced polypropylene, can be used as a plastics material for the bristle carriers 3 and/or the fastening anchors, for example.

[0091] FIG. 14 shows a sectional lateral view of a bristle carrier 3 which has bundle receptacle bores 4 of various geometries.

[0092] All of the bundle receptacle bores 4 herein are designed to be free of anchor tracks. The first two bundle receptacle bores of FIG. 14, when viewed from the left, have a bore wall 8 which in the first portion is initially cylindrical and then is conical and tapers toward the bore base.

[0093] The third bundle receptacle bore 4 from the left in FIG. 14 has an introduction chamfer which is then adjoined by a cylindrical portion of the bore wall 8. In the end portion, the bore wall 8 tapers conically toward the bore base of the bundle receptacle bore 4.

[0094] The third bundle receptacle bore 4 from the right of the bristle carrier 3 of FIG. 14 has a bore wall 8 which first has a conical design tapering toward the bore base, then transitioning into a portion which tapers even more conically toward the bore base. The double arrow plotted at the entry into the bundle receptacle bore 4 visualizes a cone angle which is presently at most 7.

[0095] The second bundle receptacle bore 4 when viewed from the right in FIG. 14 has a conical bore wall 8 which tapers toward the bore base of the bundle receptacle bore 4 and is moreover of stepped design. The stepped design serves as a retaining structure 13 and facilitates reliable fixing of a fasting anchor 6 in the bundle receptacle bore 4.

[0096] The bundle receptacle bore 4 on the extreme right of the total of six bundle receptacle bores 4 shown in FIG. 14 has a cylindrical bore wall 8 which transitions into a conically tapering end portion. A retaining structure 13 in the form of retaining grooves, which facilitate a form-fitting fixing of a fastening anchor 6 within the bundle receptacle bore 4, is formed in the cylindrical region of the bore wall 8 of this bundle receptacle bore 4.

[0097] When carrying out the method, the bristle bundles 5 conjointly with the fastening anchors 6 can be stuffed into the bundle receptacle bores 4 at a stuffing rate of at least 400 stuffing procedures per minute.

[0098] Even higher stuffing rates of, for example, 600, 800, 1000 or 1200 up to, for example, 1500 stuffing procedures per minute, can be applied when carrying out the method.

[0099] The thruster tongue 9 by which a bristle bundle 5 is incorporated conjointly with a fastening anchor 6 into a bundle receptacle bore 4 can strike the bundle receptacle bore 4 at a speed between, for example, 1.2 m/s and 4.0 m/s, preferably between 1.8 m/s and 3.5 m/s, particularly preferably between 2.2 m/s and 2.8 m/s. It is ensured in this way that the fastening anchor 6 penetrates the bundle receptacle bore 4 with sufficient kinetic energy in order to achieve the desired targeted deformation of the fastening anchor 6 while forming the previously explained anchoring structures 7.

[0100] For carrying out the method, the bristle manufacturing machine 1 thus has the stuffing tool 10 having the thruster tongue 9 in order to incorporate the bristle bundles 5 conjointly with the fastening anchors 6 into the bundle receptacle bores 4 of offered-up bristle carriers 3. FIGS. 16 to 20 show that the thruster tongues 9 depicted therein have on their respective front end 12 on narrow sides that face away from one another in each case at least one peeling edge 14.

[0101] With the aid of the peeling edges 14, material from the peripheral regions of the bundle receptacle bores 4 of the respective bristle carrier 3 can be peeled, and ultimately be displaced into the bundle receptacle bores 4 for the form-fitting fixing of the fastening anchors 6 in the bundle receptacle bores 4, as highlighted in FIGS. 10 to 13. The thruster tongue 9 which is shown in FIG. 17 has on its front end 12, adjacent to the narrow sides of the front end 12, a clearance 15 having material-guiding faces 16. The material-guiding faces 16 are aligned obliquely to a longitudinal axis of the thruster tongue 9, and face the longitudinal axis and also face one another. The material-guiding faces 16 serve to direct material of bristle carriers 3 that has been peeled from the peeling edges 14 into bundle receptacle bores 4. The thruster tongue 9 shown in FIG. 18 has on its front end 12 two clearances 15. The clearances 15 are in each case formed adjacent to one of the peeling edges 14 of this thruster tongue 9 in the front end 12 of the thruster tongue 9, and likewise provide material-guiding faces which enable peeled material of a bristle carrier 3 to be directed in the direction of a bundle receptacle bore 4.

[0102] A planar contact face 17 for a fastening anchor 6 is formed between the two clearances 15 of the thruster tongue 9 shown in FIG. 18. This contact face 17 facilitates the precise introduction of fastening anchors 6 into bundle receptacle bores 4.

[0103] Similar to the thruster tongue 9 shown in FIG. 18, the thruster tongue 9 shown in FIG. 19 likewise has two clearances 15 having material-guiding faces 16 in the front end 12 of the thruster tongue 9. In comparison to the clearances 15 shown in FIG. 18, which penetrate the thruster tongue 9 across its entire thickness from one flat side to the other flat side, thus connect the two flat sides of the thruster tongue to one another, the clearances 15 of the thruster tongue 9 shown in FIG. 19 are laterally closed.

[0104] The thruster tongue 9 shown in FIG. 20 has on its front end 12 a V-shaped longitudinal groove 18. The longitudinal groove 18 is disposed between narrow sides of the thruster tongue 9 that face away from one another, and connects said narrow sides. The V-shaped longitudinal groove 18 enables a filling level of a bristle bundle 5 fixed in the bundle receptacle bore 4 by a fastening anchor 6 to be increased by a targeted compression and further deformation of the fastening anchor 6.

[0105] In this way, a bristle product 2 which comprises a bristle carrier 3 having at least one bundle receptacle bore 4 can be manufactured by the method. A bristle bundle 5 having a fastening anchor 6 of plastics material, which is plastically deformed during incorporation into the bundle receptacle bore 4, is fastened in the bundle receptacle bore 4. The fastening anchor 6 has anchoring structures 7 which have been generated by the plastics deformation and which can be at least partially covered by material of the bristle carrier 3 that has been displaced into the bundle receptacle bore 4, as is highlighted in FIG. 13, for example.

[0106] A subject matter of the method visualized in particular in FIGS. 6 to 13 is the use of a fastening anchor 6 which has been deformed during incorporation into a bundle receptacle bore 4 of a bristle carrier 3 of a bristle product 2 and which is preferably composed of plastics material, for anchoring a bristle bundle 5 in the bundle receptacle bore 4.
