[0013] The objective of this invention is to provide a brush tool of the type described at the beginning, which achieves a good cleaning effect, especially in the seams when removing weeds, while having a long service life, wherein a narrow structure is realized.

[0014] According to the present invention, the task is solved in the brush tool mentioned at the beginning by the following method: a plurality of ribs are provided on a first substrate and / or a second substrate, filaments are arranged in a portion of the area between the first substrate and the second substrate, and a filament assembly is positioned between the first rib and the adjacent second rib, the filament assembly abutting against the first rib and the second rib, wherein the filament assembly includes at least one filament.

[0015] These filaments form the brush of the brush tool. Because they are positioned between the first and second substrates, a narrow structure in the axial direction can be achieved in a structurally simple manner. This results in good seam versatility.

[0016] Due to its narrow structure, relatively coarse bristles (brushes) can be used. This results in good cleaning performance and a long service life.

[0017] Because the filament feeding assembly is equipped with a first rib and a second rib, with multiple ribs disposed on the first substrate and / or the second substrate, a relatively large number of filaments can be positioned on the brush tool. This again ensures good cleaning performance and a long service life during brush tool operation.

[0018] In principle, it is possible to arrange exactly one filament between the first rib and the second rib. In an advantageous embodiment, multiple filaments are arranged between the first rib and the second rib. For example, filament pairs are arranged.

[0019] The first and second substrates are functional regions of the retaining disc composite, between which the filament assembly is located, and they particularly ensure axial fixation of the filament assembly. It is possible that the retaining disc composite is constructed in one or more parts (e.g., two parts). The first and second retaining discs, or the first and second substrates, are, in principle, geometric regions on the retaining disc composite. In the case of a multi-part retaining disc composite, the first and second substrates can also be implemented on different components (and in particular, formed as different components), which are subsequently joined together during the manufacture of the brush tool. Alternatively (in the case of a one-piece retaining disc composite), it is also possible that the first and second substrates are implemented on the same component, which is manufactured, for example, in an injection molding process. In particular, it is desirable that the first and second substrates be integrally formed on the same component.

[0020] Advantageously, the filament assembly between the first rib and the second rib is connected to the first rib and / or the second rib, and the brush tool has at least one of the following:

[0021] - A connection is a connection where materials lock together;

[0022] - A connection is a shape-locking connection.

[0023] This results in the filament being reliably held on the first and second retaining discs. The filament is held on the retaining disc composite using a first portion region. The filament extends beyond the retaining disc composite using a second portion region and can be used for seam cleaning during operation. The filament is optimally secured to the retaining disc composite due to material-locking and / or form-locking connections with the first and / or second ribs. This enables a long service life. The material-locking connections are, for example, adhesive or welded connections. In the case of form-locking connections, in particular, at least one tab disposed on the first and / or second substrates is embedded into the material of the filament.

[0024] In particular, the brush tool is constructed as a rotatable tool having a center that mates with the axis of rotation (of the sewing machine's shaft), wherein a machine coupling part for coupling with the sewing machine is arranged at the center. In particular, the brush tool can be connected to the sewing machine in a simple (detachable) manner.

[0025] Advantageously, the retaining disc composite is provided with axial, circumferential, and radial directions, and the brush tool has at least one of the following:

[0026] - The first substrate and the second substrate form a contact portion in the axial direction for the wire assembly;

[0027] - The filament assembly is locked to the first matrix and / or the second matrix material;

[0028] - The first rib and the second rib are respectively formed in the circumferential direction for the wire assembly between the first rib and the second rib;

[0029] - The first substrate and / or the second substrate have a contact ring that provides a contact surface for the filament assembly in a radial direction toward the center;

[0030] - The wire assembly is connected to the abutment ring material in a locking manner in the radial direction;

[0031] - The filament assembly is oriented in the radial direction;

[0032] - The ribs are oriented in the radial direction.

[0033] Because the first and second substrates are constructed as axially abutting portions, a wire fastening portion with a simple structural configuration is provided. Material-locking connections (adhesive and / or welded connections) with the first and / or second substrates can also be achieved in a simple manner. Since the first and second ribs are constructed as abutting portions in the circumferential direction, the brush fastening portion can be achieved in a simple manner, thus enabling a long service life. The corresponding brush tool can be constructed relatively thin, yet relatively thick wires can be used. This achieves good seam versatility (also suitable for narrow seams), good cleaning performance, and a long service life. When the first and / or second substrates have abutting rings, the wires or wire assemblies can be additionally connected to, or at least supported via, the abutting rings. In particular, material-locking connections can be achieved through adhesive bonding or welding. When the wire assembly is oriented radially, a relatively large number of wires can be arranged on the brush tool. Relatively thick wires can be used. Therefore, a narrow structure with good seam versatility, good cleaning performance, and a long service life is obtained.

[0034] A structurally simple construction is obtained when at least one of the following is set:

[0035] - The ribs located on the first substrate are attached to the second substrate;

[0036] - The ribs located on the second substrate are attached to the first substrate;

[0037] - The ribs located on the first substrate are integrally formed with the first substrate;

[0038] - The ribs located on the second substrate are integrally formed with the second substrate;

[0039] - The ribs that abut against the second substrate are locked to the material of the second substrate;

[0040] - The ribs that rest against the first substrate are locked together with the material of the first substrate.

[0041] Therefore, the corresponding brush tool can be made from a small number of components. In principle, it is sufficient to only set up a first substrate, a second substrate, and bristles. For example, in manufacturing the brush tool, the bristles are firmly connected to a substrate. Subsequently, another substrate is connected to the substrate mentioned at the beginning as a cover, and then the bristles are placed between the first substrate and the second substrate. Thus, a brush tool with a simple structure and simple manufacturability can be provided, which has a long service life during operation and ensures good cleaning effect.

[0042] Advantageously, the first rib has a first contact surface for the filament assembly, and / or the second rib has a second contact surface for the filament assembly, the brush tool having at least one of the following:

[0043] - The first and second mating surfaces are parallel to each other and oriented.

[0044] - The first and / or second backing surfaces are flat;

[0045] - At least one tab is disposed on the first and / or second contact surfaces, the at least one tab being recessed into the wire assembly.

[0046] Therefore, a brush tool can be manufactured in a simple manner, which can be equipped with a relatively large number of relatively coarse filaments. This enables good cleaning performance while maintaining a long service life. The brush tool can be manufactured to be very narrow. The filaments can be reliably secured to the retaining disc composite. The filaments can be constructed in a simple manner (especially having a uniform cross-section). When at least one tab recessed into the filament assembly is additionally placed on the first and / or second contact surfaces, additional form-locking can be achieved, for example, in addition to the material-locking connection with the first and / or second ribs. This also contributes to a long service life.

[0047] In an advantageous embodiment, a receiving space for the filament assembly is provided between the first substrate, the second substrate, the first rib, and the second rib, and the brush tool has at least one of the following:

[0048] - The accommodating space extends toward the first rib and toward the second rib through the planar boundary;

[0049] - The space for accommodating the brush tool is defined by an arc-shaped boundary at the center of the brush tool;

[0050] - The accommodating space opens outwards radially away from the center of the brush tool;

[0051] - The containment space has a fan-shaped shape in cross-section.

[0052] This allows for the simple manufacture of brush tools. In particular, it enables the keeping of the number of basic components to be low. In one embodiment, only a first substrate, a second substrate, and filaments are required as basic components. The filaments can be secured to the retaining disc composite in a simple and reliable manner, and are easy to manufacture. The brush tool can have a large number of relatively coarse filaments. Therefore, good cleaning performance and a long service life can be achieved during operation. Furthermore, good seam versatility is also obtained.

[0053] Furthermore, it is advantageous to have at least one of the following features:

[0054] - The first matrix is ​​constructed as a disk;

[0055] - The second matrix is ​​constructed as a disk;

[0056] - The first and second substrates are arranged concentrically with each other;

[0057] - The first and second substrates have a uniform spacing;

[0058] - Ribs are located only on the first matrix.

[0059] This results in a structurally simple construction with easy manufacturability.

[0060] Advantageously, the first substrate has a first holding region for the filament assembly and a first fixing region for the machine coupling portion, and the brush tool has at least one of the following:

[0061] - A first recess is formed at the first holding region, and the wire assembly is positioned in the first recess;

[0062] - Ribs are arranged in the first holding area;

[0063] - The rib is arranged in the first recess at the first holding area;

[0064] - The first recess is defined in the radial direction by an abutment element, and the wire assembly abuts the abutment element at its end;

[0065] - The contact element is constructed as a tab, and in particular as a ring tab;

[0066] - The abutting element is recessed into the second recess on the second substrate, and in particular abuts against the bottom of the second recess on the second substrate;

[0067] - The abutting element abuts against an edge that limits a second recess in the second substrate in the radial direction;

[0068] - The first recess extends through a flat bottom boundary;

[0069] - A first shoulder is provided between the first holding region and the first fixing region, wherein, in particular, the first shoulder is arranged on the side opposite to the second substrate.

[0070] The first recess in the first retaining region provides a accommodating space for the wire assembly in a structurally simple manner. Connection can be achieved in a simple way, for example, by material locking and / or by form locking. Fixing can be achieved in both the axial and circumferential directions by arranging ribs in the first retaining region. A structurally simple construction is obtained when the ribs are arranged in the first recess in the first retaining region.

[0071] When the first recess is defined in the radial direction by an abutment element that abuts the filament assembly at its end, a structurally simple configuration and ease of manufacturability are achieved. The abutment element allows for easy radial fixation of the filament assembly during brush tool manufacturing. Furthermore, connection with the abutment element, especially a material-locking connection, is possible. This results in high stability and a correspondingly long service life for the brush tool. When the abutment element is constructed as a tab, and especially as an annular element, and is recessed into the second recess on the second substrate, preferably abutting the bottom of the second recess on the second substrate, the abutment element can alternatively or additionally be used for a stable connection between the first and second substrates. To a certain extent, the surface area where the first and second substrates, especially the material-locking connection, are joined together is increased via the abutment element. It is particularly advantageous that the abutment element abuts the edge of the second recess that defines the second substrate in the radial direction. Therefore, an additional connection between the first and second substrates can also be achieved in the radial direction via the abutment element.

[0072] When the first recess passes through the flat bottom boundary, a simple connection with the filament, for example, a material, can be achieved. The shoulder arranged between the first holding region and the fixing region on the first substrate allows for simple machine coupling and enables the brush tool to be constructed very thin.

[0073] For the same reason, it is advantageous that the second substrate has a second holding region for the filament assembly and a second fixing region for the machine coupling portion, and the brush tool has at least one of the following:

[0074] - A second recess is formed at the second holding area, and the wire assembly is positioned in the second recess;

[0075] - The second recess is opposite to the rib on the first substrate;

[0076] - The second recess is bounded by an edge in the radial direction;

[0077] - This edge is spaced apart from the end of a portion of the filament assembly, which is held on the retaining disc composite by means of this end;

[0078] - A splice, particularly an annular splice, is arranged between the edge and the wire assembly, the splice being located on the first substrate;

[0079] - The second recess on the second substrate has a flat bottom;

[0080] - A second shoulder exists between the second holding region and the second fixing region, wherein, in particular, the second shoulder is arranged on the side opposite to the first substrate.

[0081] For example, when the corresponding abutment element abutting the end of the wire assembly defines the second recess, a structurally simple and manufacturable construction of the first and second substrates is obtained. In particular, the rib is then arranged on the other substrate. An additional connection between the first and second substrates can be achieved radially via the edges. A connection, particularly a material-locking connection, between the first and second substrates can be established in the axial and / or radial directions via tabs, especially annular tabs on the first substrate. This results in a large connection surface.

[0082] Advantageously, the retaining disc composite has a composite retaining region formed by a first retaining region and a second retaining region, and a composite fixing region formed by a first fixing region and a second fixing region. In particular, a machine coupling part is arranged at the composite fixing region.

[0083] Furthermore, it is advantageous to have at least one of the following features:

[0084] - The composite holding region has a first thickness, which is uniform throughout the composite holding region;

[0085] - The composite fixing region has a second thickness, which is consistent throughout the composite fixing region;

[0086] - The first thickness is greater than the second thickness;

[0087] - The fixed region of the composite retracts relative to the holding region of the composite in the axial direction.

[0088] This allows for the provision of correspondingly thin brush tools. Sufficiently large space is provided for filament holding, ensuring secure filament fastening. Machine coupling on the composite fixing area can be achieved in a simple manner.

[0089] Advantageously, the filament assembly rests against the abutment element on its end side, and the brush tool has at least one of the following:

[0090] - The contact element is a ring-shaped element;

[0091] - The ribs are spaced apart from the abutting elements in the radial direction;

[0092] - The contact element is spaced apart from the machine coupling part in the radial direction;

[0093] - The abutment element is located on the second substrate, and the rib is located on the first substrate.

[0094] This results in a brush tool that can be manufactured in a simple manner. The number of parts used to manufacture the brush tool can be kept low. Reliable fastening of the filament assembly is achieved. This, in turn, results in a long service life.

[0095] In an advantageous embodiment, the wire feeding assembly is equipped with at least one tab, and the brush tool has at least one of the following:

[0096] - At least one tab has at least one contact surface that abuts against the wire assembly;

[0097] - The wire assembly is material-locked and / or shape-locked to at least one tab;

[0098] - At least one tab is recessed into the filament assembly, and in particular into and / or surrounded by the material of the filament assembly;

[0099] - At least one tab is configured as a push element for the material of the wire assembly.

[0100] By providing at least one tab, additional fastening possibilities are pre-defined for the filament assembly. This enables higher fastening stability and, in turn, increases the service life of the brush tool. In addition to the first or second rib and the direct contact surfaces on the first and / or second substrates, additional material-locking and / or form-locking connections can be achieved via at least one tab.

[0101] In an advantageous embodiment, at least one tab is arranged and configured to connect multiple filaments. The multiple filaments, particularly the first and second filaments, can abut against the tab to achieve additional fastening. This results in simple manufacturability and reliable fastening of the brush tool.

[0102] Alternatively or additionally, at least one tab may be arranged and configured for connection with a single wire. For example, such at least one tab may be configured as a shape-locking element recessed into the wire.

[0103] In an advantageous embodiment, at least one tab is positioned between respective first and second ribs. In principle, this tab can be used to establish a shape-locking with the wires. Alternatively or additionally, it is also possible for at least one tab to abut against the first and second wires, wherein the first wire abuts against the first rib and the second wire abuts against the second rib. This provides additional abutment surfaces in the circumferential direction.

[0104] Advantageously, at least one of the following is provided:

[0105] - At least one splice is centered between the first rib and the second rib;

[0106] - At least one tab is located on the same substrate where the first rib and the second rib are located;

[0107] - At least one tab is oriented in the radial direction;

[0108] - At least one patch is square;

[0109] - At least one filament is attached to at least one tab using its outer side;

[0110] - The first filament of the filament assembly rests on at least one tab, wherein the first filament rests on a first rib; and the second filament of the filament assembly rests on at least one tab, wherein the second filament rests on a second rib.

[0111] Since at least one tab is centrally located between the first and second ribs, an additional abutment surface is provided in the circumferential direction, which in particular has an extension length in the radial direction. When at least one tab is located on the same substrate as the first and second ribs, simple manufacturability, and especially overall manufacturability, is achieved. A large abutment surface is provided due to the radial orientation of the tab. In the case where at least one tab is squarely configured, two wire assemblies can be abutted on different sides of the at least one tab. When at least one wire abuts against at least one tab using its outer side, a corresponding connection can be obtained in a simple manner, which can also be material-locked. In a structurally advantageous embodiment, the tab is located between the first and second wires of the wire assembly, abutting against both the first and second wires, and is particularly material-locked to them. Therefore, the first and second wires can be supported outside the retaining disc composite in a simple manner, and here fixed to the retaining disc composite in a simple and reliable manner.

[0112] Alternatively or additionally, at least one tab may have at least one intrusion tip that penetrates into the material of the filament. This makes it possible to anchor at least one tab to the corresponding filament in a simple manner during manufacturing, so as to achieve a form-locking connection, in particular.

[0113] Advantageously, at least one tab having at least one penetrating tip is arranged on or beside the rib, and in particular, the brush tool has at least one of the following:

[0114] - At least one splice is submerged in the wire assembly;

[0115] - At least one tab is closer to the rib it is assigned to than to the adjacent rib;

[0116] - At least one tab is connected to a single wire;

[0117] - The ribs are fitted with multiple tabs, which are spaced apart and are specifically configured as legs on the ribs.

[0118] It enables additional shape-locking connections. This results in simple and reliable wire fastening. It also extends the lifespan of the brush tool. Furthermore, it improves the manufacturability of the brush tool.

[0119] Furthermore, it is advantageous that the first rib and the second rib are arranged on one of the first and second substrates, and at least one tab is arranged on the other substrate. The other substrate then forms a cover at least around the area surrounding the first and second ribs. When at least one tab is arranged on this cover, an additional connection between the wire assembly and the retaining disc composite can be achieved. This further improves service life.

[0120] Particularly advantageous is that at least one first-type tab is arranged between the first and second ribs, the first-type tab abutting against the outer side of the filament, and at least one second-type tab is arranged on or beside the rib, the second-type tab being recessed into the filament. This results in simple manufacturability. This results in high stability of the filament fastened to the retaining disc composite. This also results in a long service life. In particular, the components of the brush tool (and here preferably the first substrate as a component itself, the second substrate as a component itself, or a component comprising the first and second substrates, and the filament) are adhesively and / or joined by ultrasonic welding (and thus material-locked) and / or in an injection molding process (and thus material-locked).

[0121] Furthermore, it is particularly advantageous to provide at least one third-type tab arranged on the cover. The substrate without ribs forms, to a certain extent, a cover for the substrate with ribs. When at least one tab is arranged on the cover, additional connections to the filament assembly can be achieved. For example, the at least one tab on the cover is configured as a recessed element that is recessed to a certain extent into the filament assembly from above. For example, each filament of the filament assembly is thus assigned at least one tab, which is correspondingly recessed to the filament from above.

[0122] In an advantageous embodiment, the filament assembly includes a first filament and a second filament, and more particularly, exactly one filament pair. This makes it possible, at least in the initial state (unused state) of the brush tool, for the first and second filaments to support each other. This results in high stability. Effective seam cleaning is achieved. Furthermore, a large number of filaments can be positioned on the retaining disc composite.

[0123] Advantageously, the filaments of the filament assembly are arranged side-by-side in the circumferential direction and, particularly, do not stack in the axial direction. This allows for the construction of a brush tool with a relatively small thickness (in the axial direction). This results in high seam versatility. Specifically, all the filaments (under no load) are arranged in a plane perpendicular to the axis of rotation. During processing, exactly one filament acts on the processing area in the axial direction (while multiple filaments can act in the circumferential direction).

[0124] More advantageously, at least in the initial state, the filaments of the filament assembly are in contact with each other in at least a portion of the area, and particularly loosely. The corresponding portion, in particular, is the area where the filaments of the filament assembly extend beyond the retaining disc composite. Therefore, the filaments of the filament assembly can support each other. This results in an effective cleaning effect. The initial state is, in particular, the unused state of the brush tool. After cleaning operation, it is theoretically possible that the filaments permanently deform, to the point that they no longer support each other or are no longer fully supported within the respective filament assemblies.

[0125] Advantageously, the filaments are rectangular or square in cross-section, and in particular, the filaments are arranged in the filament assembly such that, at least initially and in at least a portion of the area, the planes of the filaments loosely touch. Therefore, the filaments of the filament assembly can support each other over a large area. This results in an effective cleaning effect. The initial state is especially the unused state. After the brush tool has been used, this support is at least partially eliminated.

[0126] Advantageously, at least one of the following is provided:

[0127] - It is set with at least forty filaments, and especially at least forty-six filaments, and especially at least fifty filaments, and especially at least fifty-six filaments;

[0128] - It is provided with at least twenty filament assemblies, and in particular at least twenty-three filament assemblies, and in particular at least twenty-five filament assemblies, and in particular at least twenty-eight filament assemblies, wherein, in particular, the filament assemblies have filament pairs;

[0129] - The wire components are evenly distributed in the circumferential direction.

[0130] A good cleaning effect and long service life were achieved by using a suitable number of filaments or filament assemblies. The number of filaments was maximized in the circumferential direction.

[0131] Even more advantageous is that the bending stiffness of the wire is at least 9000 N / mm. 2 And especially at least 10000 N / mm 2 And especially at least 13000 N / mm 2Therefore, it achieves effective cleaning and a long service life. Furthermore, it offers ease of use for the operator.

[0132] Furthermore, it is advantageous that the wire extends at least 3 cm beyond the retaining disc composite, and particularly at least 4 cm. This allows for both excellent cleaning performance and simple operability.

[0133] Furthermore, good cleaning results can be achieved when the wire probe extends at least 7 cm beyond the retaining disc composite, and especially at least 6 cm. This also results in simple operability. The operator can easily aim the brush tool at the seam to be cleaned.

[0134] Advantageously, the filament thickness is in the range of 2mm to 4mm, and especially in the range of 2.5mm to 3.5mm. Therefore, high cleaning efficiency is achieved in narrow structural situations.

[0135] Furthermore, the filaments are made of plastic. This allows for effective cleaning of the seams and keeps the risk of damage to the materials forming the seams (such as paving stones or the like) low.

[0136] It is possible that the first retaining disc or first base and the second retaining disc or second base are separate components, or implemented on separate components that are subsequently connected to each other, or that the first retaining disc or first base and the second retaining disc or second base are implemented on a single component. In one embodiment, for example, the first base and the second base are manufactured separately and then connected to each other during the manufacture of the brush tool, wherein the filament assembly is positioned between the first base and the second base. In an alternative embodiment, a (one-piece) retaining disc composite is manufactured, which is in particular a single component and includes the area of ​​the first base and the second base as the single component. In particular, the retaining disc composite having the first base and the second base is one-piece and here especially integral. For example, it is manufactured as an injection-molded part. During manufacturing, the filament assemblies are encapsulated accordingly, for example, so that these filament assemblies are fixed together with the retaining disc composite having the first base and the second base.

[0137] In one embodiment, a first retaining disc composite, consisting of a first substrate and a second substrate, is provided with a plurality of openings, wherein at least one opening is located between a first rib and an adjacent second rib and is associated with a filament assembly. This at least one opening allows the associated filament assembly to be influenced during the manufacture of the retaining disc composite having the filament assembly. For example, when the retaining disc composite is integrally manufactured by an injection molding process (where the filament assembly has been placed into a corresponding injection mold), the filament assembly can be influenced via the opening through a portion of the mold, causing the filament assembly to deform and bulge (especially under heating). This improves the connection with the retaining disc composite and, in particular, allows for the creation of side recesses or shape-locking connections through material pushing in the corresponding areas (especially in addition to material-locking connections).

[0138] In this respect, it is advantageous to have at least one of the following features:

[0139] - The first matrix has a first ring comprising spaced-apart openings;

[0140] - The second matrix has a second ring containing spaced-apart openings;

[0141] - The openings of the first and second rings are aligned with each other;

[0142] - Between the first rib and the adjacent second rib, there is exactly one opening on the first substrate and / or the second substrate, and in particular, there is a filament assembly configured as a filament pair at the opening;

[0143] - The first matrix and the second matrix form an integrated retaining disk complex.

[0144] In principle, it is possible to configure a first substrate with a first ring containing spaced-apart openings, and a second substrate with a second ring containing spaced-apart openings. Specifically, at least one opening is then respectively assigned to both sides (relative to the axial direction) of the wire assembly. Thus, for example, it is possible to use a die portion and a mating die portion in a simple manner to achieve corresponding permanent deformation of the wire assembly via the openings.

[0145] Of particular advantage is that the openings of the first and second rings are aligned with each other so as to obtain corresponding influence from both sides in the axial direction.

[0146] In particular, there is exactly one opening between the first rib on the first substrate and / or the second substrate and the adjacent second rib, and preferably, the filament assembly configured as a filament pair is located in this opening. This results in simple manufacturability.

[0147] It is particularly advantageous that the first and second substrates form an integral retainer complex, which is made especially by injection molding.

[0148] More advantageously, the filament assembly positioned between the first rib and the adjacent second rib has at least one raised portion in the circumferential direction (relative to the axial direction of the brush tool) that mates with at least one corresponding opening, wherein, in particular, this at least one raised portion is assigned to an adjacent filament assembly. During the manufacture of the corresponding brush tool, the associated filament assembly can be influenced via the at least one opening. This allows the filament assembly to be permanently deformed by the corresponding mold or mold / mating mold, thereby forming the raised portion. This enables the realization of a side recess or shape-locking connection of the corresponding filament assembly on the retaining disc composite, which is particularly beneficial for material-locking connections. The corresponding opening is used as an auxiliary device during the manufacture of the brush tool to create the raised portion on the filament assembly.

[0149] More advantageously, at least one raised portion abuts against the rib and / or forms a side recess. This results in manufacturability with simple manufacturing technology, wherein an optimized connection of the filament assembly on the retaining disc composite is achieved. In particular, in the radial direction (in addition to the preferred material-locking connection), a side recess or shape-locking connection of the filament assembly on the retaining disc composite is also obtained. This side recess or shape-locking connection can be established via an opening, and thus can be constructed relatively simply by means of a mold or injection molding die.

[0150] According to the present invention, a seam cleaning machine of the type described at the beginning is provided, wherein a brush tool according to the present invention is arranged thereon, and in particular detachably arranged.

[0151] In particular, the corresponding seam cleaning machine used to remove weeds between seams has the advantages already explained in conjunction with the brush tool according to the invention.

[0152] Advantageously, the tool head is positioned on a retaining rod assembly, which is configured to allow a standing operator to perform the seam cleaning process. This results in simple operability.

[0153] In particular, the brush tool according to the invention is used to remove weeds from seams, or the seam cleaning machine according to the invention is used to remove weeds from seams, especially in outdoor areas. Attached Figure Description

[0171] The seam cleaning machine according to the present invention Figure 1 and Figure 2 The embodiment shown in the middle (partial view) and labeled 10 is particularly used for removing weeds from the joints between paving stones or the like.

[0172] The sewing machine 10 includes a tool head 12. The tool head 12 is located on a retaining rod assembly 14. The retaining rod assembly 14 is used to hold and guide the sewing machine 10 by a standing operator.

[0173] In one embodiment, the length of the retaining rod device 14 between the tool head 12 and the proximal end (relative to the operator) can be adjusted in a way that can be fixed.

[0174] For example, the retaining rod device 14 has a first rod 16 and a second rod 18. A coupling portion 20 is provided, for example, arranged on the second rod 18. The first rod 16 is telescopically guided within the second rod 18. The coupling portion 20 is used to fix the relative positioning of the first rod 16 relative to the second rod 18.

[0175] A handle unit 22 is mounted on the retaining rod assembly 14, particularly on the second rod 18. The handle unit 22 includes a bow-shaped handle 24. Furthermore, in one embodiment, a switch 26 for turning the sewing machine 10 on and off is also arranged on the handle unit 22.

[0176] It can be configured such that an electrical grid cable 28 for power supply is guided via the handle unit 22.

[0177] It is also possible that the sewing machine 10 is battery-powered. The corresponding battery unit is located, for example, on the handle unit 22, the retaining rod device 14, or the tool head 12. The battery unit can be securely mounted or removable.

[0178] In one embodiment, the bow-shaped handle 24 is aligned with the center plane 30 of the tool head 12. The center plane 30 also forms the center plane of the bow-shaped handle 24.

[0179] This makes it easy for the operator to align the tool head 12 with the seam to be cleaned.

[0180] The bow-shaped handle 24 is configured to be gripped by the operator's hand in order to hold and guide the sewing machine 10.

[0181] In addition, a separate handle unit 32 is disposed on the retaining rod assembly 14 at a distance from the handle unit 22. The handle unit 32 is configured such that the operator can hold the sewing machine 10 from above with the other hand, compared to the hand holding the bow-shaped handle 24. For this purpose, the handle unit 32 has a handle 34, which is oriented laterally to the central plane 30.

[0182] To hold the handle unit 22, the operator's hand is oriented substantially parallel to the center plane 30. The operator's other hand, which is holding the handle unit 32, is oriented laterally to the center plane 30.

[0183] The tool head 12 includes a housing 36. A motor, particularly an electric motor, is arranged in the housing 36. (It is also possible, in principle, that the sewing machine 10 includes, for example, an internal combustion engine).

[0184] The housing 36 includes a tab 38.

[0185] A tool shaft 40 is arranged on the connecting piece 38. A tool coupling part 42 is mounted on the tool shaft 40. The brush tool 44 can be detachably connected to the tool shaft 40 via the tool coupling part 42. The tool shaft 40 has a rotation axis 46. During the operation of the sewing machine 10, the brush tool 44, which is fixed by the tool shaft 40 via the tool coupling part 42, rotates around the rotation axis 46.

[0186] The axis of rotation 46 is oriented perpendicular to the central plane 30.

[0187] The tool spindle 40 is spaced apart from the housing 36. A torque transmission device is guided within the tab 38 to transmit torque from the corresponding motor to the tool spindle 40.

[0188] The housing 36 has a notch 48 that is defined to one side by a tab 38 and by a vessel wall 50. The vessel wall 50 is an end-side vessel wall that is oriented transversely to, for example, perpendicular to, the central plane 30.

[0189] The brush tool 44 is located in gap 48.

[0190] The brush tool 44 is equipped with a protective cover 52, which covers the brush tool 44 in the non-operational area.

[0191] The brush tool 44 is located at least approximately on the center plane 30.

[0192] The protective cover 52 is provided with an arrow-shaped marking 54, which is located on the same plane as the brush tool 44, and in particular on the same plane as the bristles (brush) of the brush tool 44.

[0193] In particular, the sign 54 is located on the central plane 30.

[0194] The label section 54 displays the effective range of the brush tool 44 to the standing operator, making it easier for the operator to "find" the seams for cleaning.

[0195] In one embodiment, the protective cover 52 is fixed to the tab 38.

[0196] An embodiment of the corresponding seam cleaning machine is disclosed in DE 10 2017 121 154 A1, which is explicitly and fully referenced herein.

[0197] According to the present invention, the brush tool 44 is as follows Figures 3 to 12 One embodiment shown includes a first retaining disc 56, a second retaining disc 58, and a plurality of wires 60.

[0198] In one embodiment, the brush tool 44 is made of only three basic components: (i) a first retaining disc 56, (ii) a second retaining disc 58, and (iii) a filament 60.

[0199] The first holding disc 56 and the second holding disc 58 form a holding disc complex 62.

[0200] The first holding disc 56 and the second holding disc 58 are, in principle, the regions of the holding disc complex 62.

[0201] In the illustrated embodiment, the first retaining disc 56, the second retaining disc 58, and the filament 60 are separate components that are connected to each other during the manufacture of the brush tool.

[0202] In an alternative embodiment, the first retaining disc 56 and the second retaining disc 58 are configured together to form a single component, which is thus a one-piece and, in particular, integral component. Therefore, the retaining disc composite 62 is a single piece.

[0203] The following describes an embodiment in which the first retaining disc 56 and the second retaining disc 58 are separate components that are connected to each other during manufacturing.

[0204] The first retaining disc 56 includes a first substrate 64. The second retaining disc 58 includes a second substrate 66. The second substrate forms a cover over the first substrate 64.

[0205] The first retaining disc 56 is concentric with the first base 64 and the second retaining disc 58 is concentric with the second base 66. The retaining disc composite 62 is provided with an axial direction 68, which is oriented transversely to the bases 64 and 66. When the brush tool 44 is mounted on the sewing machine 10, the axial direction 68 is parallel to or coincides with the axis of rotation 46.

[0206] The first substrate 64 and the second substrate 66 are constructed in a circular shape; they are constructed as disks.

[0207] The retaining disk composite 62 is equipped with a radial direction 70 that is transverse to the axial direction 68, and a circumferential direction 72 that is transverse to both the axial and radial directions 70 (see...). Figure 3 Axial direction 68, radial direction 70, and circumferential direction 72 are the corresponding fundamental vector directions in the cylindrical coordinate system.

[0208] The brush tool 44 has a center 74. A machine coupling part 76 is mounted on the center 74. The brush tool 44 can be connected to the sewing machine 10 at the tool coupling part 42 via the machine coupling part 76. A connecting part that resists relative rotation is provided, so that the brush tool 44, which is fixed thereto, can rotate together with the tool shaft 40.

[0209] In order to form center 74, first substrate 64 has first center 78, and second substrate 66 has second center 80.

[0210] On the first center 78 and the second center 80, the first base 64 and the second base 66 each have through openings 82, wherein the corresponding openings 82 are aligned. The tool shaft 40 can extend through these openings for fixation against relative rotation.

[0211] The sewing machine 10 includes a securing element 84 ( Figure 2 The brush tool 44, placed on the tool coupling part 42 via the machine coupling part 76, can be secured in the axial direction 68 by the securing element 84. It is possible that the securing element 84 also ensures a secure fixation against relative rotation, or that the tool coupling part 42 and the machine coupling part 76 are configured accordingly to provide a fixation against relative rotation.

[0212] The brush tool 44 has a retaining area 86 and a fixing area 88 (see, for example, see...) Figure 10 The wire 60 is held in the holding region 86. A machine coupling part 76 and an opening 82 are arranged in the fixed region 88. Referring to the radial direction 70, the holding region 86 is arranged outward, while the fixed region 88 is arranged inward. The holding region 86 surrounds the fixed region 88 in a ring shape.

[0213] The holding region 86 includes a first holding region 86a on the first substrate 64 and a second holding region 86b on the second substrate 66. The fixing region 88 includes a first fixing region 88a on the first substrate 64 and a second fixing region 88b on the second substrate 66.

[0214] The first substrate 64 includes a first recess 90 (see...) Figure 11The first recess 90 is located on the first holding region 86a. The first recess 90 is defined by a first bottom 92. The first bottom 92 is particularly flat. In the radial direction toward the first center 78, the first recess 90 is defined by an annular tab 94.

[0215] The annular tab 94 is circular and forms an annular surface as the edge boundary of the first recess 90. It also forms an abutment ring, which will be described in detail below.

[0216] The first recess 90 is open in the radial direction away from the first center 78 and opens toward the second substrate 66.

[0217] The second substrate 66 has a second recess 96 at the holding region 86. The second recess 96 is defined by a second bottom 98 in the axial direction 68. The second bottom 98 is particularly flat.

[0218] Towards the second center 80, in the radial direction 70, the second recess 96 is bounded by the edge 100.

[0219] The second recess 96 is open in the radial direction 70 away from the second center 80 and in the axial direction 68 toward the first base 64.

[0220] The first recess 90 and the second recess 96 each have the shape of a (hollow) ring.

[0221] The first substrate 64 and the second substrate 66 are matched to each other such that the annular tab 94 of the first substrate 64 is located in the second recess 96 and abuts against the second bottom 98, particularly at the end side (referring to the axial direction 68). Furthermore, the annular tab 94 abuts against the edge 100 of the second recess 96 of the second substrate 66 via the first side 102.

[0222] Furthermore, the first substrate 64 and the second substrate 66 are abutted against each other at a fixed region 88 via corresponding planes 104 (of the first substrate 64) and 106 (of the second substrate 66).

[0223] In an advantageous embodiment, a connection to the mating surface is provided. This connection is particularly a material-locking connection. This material-locking connection is established, for example, by an adhesive material or by welding, such as ultrasonic welding. In an alternative embodiment, the corresponding connection is established by encapsulation in an injection molding process.

[0224] To provide a recessed area for the second recess 96, the annular tab 94 is configured to extend beyond the plane 104 of the first substrate 64. The corresponding height by which the annular tab 94 extends beyond the plane 104 in the axial direction 68 is substantially the same as the depth of the second recess 96 relative to the surface 106 in the axial direction 68.

[0225] The first recess 90 and the second recess 96 form a receiving space 108 in the holding region 86 between the first substrate 64 and the second substrate 66 on the holding disc composite 62. The filament 60 is positioned in this receiving space.

[0226] The retaining disc composite 62 has a first thickness 110 at the retaining region 86 (in the axial direction 68). It has a second thickness 112 at the fixing region 88 (outside the machine coupling portion 76). Figure 11 ).

[0227] The first thickness 110 is greater than the second thickness 112.

[0228] At the transition from the holding region 86 to the fixing region 88 (from the first holding region 86a to the first fixing region 88a), a first shoulder 114 is formed on the first base 64. Correspondingly, a second shoulder 116 is formed on the second base 66 (at the transition from the second holding region 86b to the second fixing region 88b).

[0229] At the first shoulder 114 and the second shoulder 116, the transition from the first thickness 110 to the second thickness 112 on the retaining disc complex 62 occurs in a particularly abrupt manner.

[0230] The first shoulder 114 and the second shoulder 116 have the same radial spacing with the center 74.

[0231] The abutting side 118 of the first side 102 of the edge 100, on which the annular tab 94 is attached, is spaced apart from the second shoulder 116 in the radial direction 70. This spacing is... Figure 11 The figure is denoted by reference numeral 120.

[0232] The first side 102 of the annular tab 94 is spaced apart from the first shoulder 114, wherein the corresponding spacing in the radial direction corresponds to the spacing 120.

[0233] The wire 60 is attached to the second side 103 of the annular connector 94, which is opposite to the first side 102.

[0234] Thus, a region 122 is formed on the retaining disc composite 62 at the transition between the retaining region 86 and the fixing region 88. This region has a large first thickness 110 and an extension length in the radial direction 70 (corresponding to the spacing 120).

[0235] Despite the presence of the first shoulder 114 and the second shoulder 116, the stability of the retaining disk complex 62 is still increased.

[0236] Planes 104 and 106 are located on a central plane 124, which is perpendicular to the axial direction 68. The retaining disk complex 62 is configured to be at least approximately mirror-symmetrical about the central plane 124 in terms of its external shape.

[0237] The fixed region 88 retracts relative to the holding region 86 in a mirror-symmetric manner with respect to the central plane 124.

[0238] A plurality of ribs 126 are disposed on the first substrate 64. Adjacent ribs are spaced apart from each other in the circumferential direction 72. The ribs 126 are evenly distributed in the circumferential direction 72.

[0239] Ribs 126 are arranged in the first recess 90 on the first base 64. These ribs are spaced apart from the annular tab 94 in the radial direction 70.

[0240] In the illustrated embodiment, all the ribs 126 are arranged on the first substrate 64, and the annular tab 94 is also located on the first substrate.

[0241] In particular, the first substrate 64 is integrally formed with the annular tab 94 and the rib 126.

[0242] This embodiment achieves simple manufacturability in terms of the positioning of the wire 60, which will be explained in detail below.

[0243] In principle, it is also possible that the ribs are located only on the second substrate 66, or that some of the ribs are located on the first substrate 64 and some of the ribs are located on the second substrate 66.

[0244] Specifically, the ribs 126 are configured with a height in the axial direction 68, such that these ribs abut against the second substrate 66 and therein against the second bottom 98 of the second recess 96 of the second substrate 66. Therein, in particular, a material-locking connection is provided between the ribs 126 and the second substrate 66. This material-locking connection is, for example, an adhesive connection or a welded connection, such as an ultrasonic welded connection.

[0245] Rib 126 is oriented in the radial direction with reference to the central plane 127.

[0246] Each rib 126 includes a first abutment surface 128 and an opposite second abutment surface 130 on its lateral side. A wire assembly can be abutted on the first abutment surface 128 and the second abutment surface 130, wherein the wire assembly abutting on the first abutment surface 128 is different from the wire assembly abutting on the second abutment surface 130.

[0247] The wedge-shaped rib 126 is configured such that the first abutment surface 128 of the first rib 132 and the second abutment surface 130 of the adjacent second rib 134 are at least substantially parallel.

[0248] This allows filaments that can be made in a simple manner and have, in particular, square or rectangular cross-sections to be positioned and fixed between the first rib 132 and the corresponding second rib 134 in a simple manner.

[0249] A receiving space 136 for the filament assembly 138 is formed between adjacent first ribs 132 and adjacent second ribs 134. The receiving space 136 is bounded in the circumferential direction by the first ribs 132 and the second ribs 134, and here bounded by the corresponding first contact surface 128 of the first rib and by the corresponding second contact surface 130 of the other rib.

[0250] In the axial direction, the corresponding receiving space 136 is bounded by the first bottom 92 of the first base 64 and the second bottom 98 of the second base 66. In the radial direction toward the center 74, the corresponding receiving space 136 is bounded by the annular tab 94.

[0251] The receiving space 108 is divided into multiple separate receiving spaces 136 by ribs 126. The receiving spaces 136 open outward on the edge side, that is, open away from the center 74 in the radial direction 70.

[0252] Each filament assembly 138 is positioned in its respective receiving space 136. The filament assembly 138 can be composed of a single filament 60 or multiple filaments.

[0253] In the illustrated embodiment, the filament assembly 138 is composed of a first filament 140 and a second filament 142, i.e., it is composed of filament pairs.

[0254] The wire assembly 138 is positioned on the receiving space 136, and thereon, on the end side, it is abutted against the annular tab 94 and connected thereto, in particular, in a material locking manner.

[0255] In the circumferential direction, the wire assembly 138 abuts against the first rib 132 and the second rib 134 and is connected thereto, in particular, in a material locking manner.

[0256] In the axial direction, the wire assembly 138 rests against the first bottom 92 and against the second bottom 98, and is particularly connected to it in a material-locking manner.

[0257] Here, the wires 60 are not stacked in the axial direction 68 (see [reference]). Figure 6 That is, there is only one row of wire assemblies 138 in the axial direction 68, wherein the wire assemblies 138 are distributed on the retaining disc composite 62 in the circumferential direction 72.

[0258] Advantageously, the first substrate 64 and the second substrate 66 are made of a plastic material, such as PA6. The filament 60 is preferably made of a plastic material, such as PA612. This prevents surface scratches during effective seam cleaning.

[0259] The wire 60 is configured to have a bending stiffness of at least 9000 N / mm². 2 And advantageously at least 10000 Nmm 2 And especially at least 13000 Nmm 2 .

[0260] In one embodiment, the wires 60 have a square or rectangular cross-section. Thus, they have at least a generally hexagonal shape.

[0261] The filaments 60 or filament assemblies 138 have a first portion region 144 by which they are located on the retaining disc composite 62 and between adjacent ribs 126. They also have a second portion region 146 by which they extend beyond the retaining disc composite.

[0262] The ends 148 of the filament 60 are formed on the second region 146. In particular, these ends 148 are used to achieve the effect of the butt joint during the cleaning process. The ends 148 are the processed ends.

[0263] Specifically, the second region 146 is configured to have a radial length of at least 3 cm, and more particularly at least 4 cm.

[0264] Furthermore, the length of the second part region 146 is at most 7 cm, and more specifically at most 6 cm.

[0265] In a specific embodiment, the length of the second region 146 is approximately 4.75 cm.

[0266] In a specific embodiment, the total length of the filament 60 (as a combination of the length of the first part region 144 and the second part region 146) is approximately 6 cm.

[0267] In a specific embodiment, the diameter of the retaining disk composite 62 in the radial direction 70 is approximately 8.5 cm.

[0268] In an advantageous embodiment, as described above, the filament 60 has a square or rectangular cross-section.

[0269] In particular, the corresponding side length is between 2mm and 4mm, and especially between 2.5mm and 3.5mm.

[0270] In a specific embodiment, the wire 60 has a square cross-section with a side length of 3 mm.

[0271] In the wire assembly 138, the respective first wire 140 and second wire 142 are secured to the retaining disc composite 62 via a first portion region 144. Here, the securing includes material locking connections, such as adhesive connections or as welded connections (which are established, for example, by ultrasonic welding).

[0272] As will be discussed in detail below, it is also possible to add or alternatively install material locking connections.

[0273] In the second region 146, the first filament 140 and the second filament 142 are loosely abutted together by their respective facing planes 150. There is contact, but no "permanent" connection. The first filament 140 and the second filament 142 of the filament assembly 138 are supported by each other via the surfaces 150. In the first region 144, the filament assembly 138 is supported on the ribs 126 in the circumferential direction. Here, the corresponding abutments are additionally secured by a material-locked connection (and, as will be explained below, also by a form-locked connection).

[0274] In the second part of region 146, loose support is provided for the filaments 140 and 142 of the filament assembly 138.

[0275] This support is especially important in the initial state of the brush tool 44. After cleaning operation, permanent deformation of the filament 60 may also occur, so that the filaments 140 and 142 of the filament assembly 138 no longer support each other, or only support each other in some areas.

[0276] A tab 152 is arranged between adjacent ribs 126 (between the first rib 132 and the second rib 134). In particular, when the filament assembly 138 includes filament pairs, the tab 152 is centrally located between the first rib 132 and the second rib 134. The tab 152 is spaced apart from the annular tab 94.

[0277] When the wire assembly 138 includes two or more wires, a plurality of tabs are positioned between the first rib 132 and the second rib 134. In particular, when the wire assembly includes n ribs, (n-1) tabs 152 are arranged between the ribs 132 and 134.

[0278] The splice 152 is inserted into the filament assembly 138 and is positioned between the first filament 140 and the second filament 142 of the respective filament assembly 138.

[0279] Specifically, the corresponding tabs 152 are arranged on the same substrate, on which ribs 126 are also disposed. In the illustrated embodiment, the tabs 152 are located on the first substrate 64. The tabs 152 are formed between adjacent ribs 132, 134 as abutment surfaces for the first wire 140 and the second wire 142. Thus, in the circumferential direction, an additional abutment element can be provided between the first rib 132 and the second rib 134.

[0280] In particular, the wires 140, 142 of the wire assembly 138 are also material-locked (e.g., adhesively or via a welded connection) to the same tab 152 to which they are attached.

[0281] The tabs 152 are of the first type. In particular, they provide additional contact surfaces. In principle, it is also possible here that the tabs 152 are configured such that they accordingly push or sink into the material of the filament 60.

[0282] Rib 126 also mates with the second type of splice 154 (see...) Figure 9 ).

[0283] The first type of splice 152 is used in particular to fix two adjacent wires 140, 142.

[0284] The second type of splice 154 is used in particular to additionally fix the wire in the area of ​​rib 126.

[0285] The tab is configured such that it sinks into the wire 60 and thereby provides a shape-locking connection.

[0286] In particular, a form-locking connection is provided relative to the circumferential direction 72 and relative to the radial direction 70.

[0287] In one embodiment, two second-type tabs 154 are arranged spaced apart on the ribs toward their respective receiving spaces 136. These tabs form, to some extent, legs on their respective ribs 126.

[0288] Since a single rib 126 defines two receiving spaces 136, four such second-type tabs 154 are arranged.

[0289] It is also possible that this second type of patch 154 is located on the corresponding first bottom 92.

[0290] In the manufacture of the brush tool, to a certain extent, a first substrate 64 having ribs 126 and annular tabs 94 is used as a substrate. Additionally, a first type of tab 152 is also present.

[0291] Wires 140 and 142 are inserted. They are then pressed onto the second type of tab 154. The second type of tab 154 is thus able to sink into the material of the wire 60, or sink into or subsequently completely penetrate the material of the wire 60 during the heating or welding process.

[0292] In this process, the wire 60 is placed between the respective tab 152 and the adjacent rib 126, wherein the adjacent wires are supported by each other via their surfaces 150.

[0293] What can be configured here is that the second type of splice 154 has an intrusion tip so as to be properly inserted into the material of the filament 60.

[0294] In addition, there is a third type of splice 156 (see Figure 11 These third-type tabs 156 are arranged on the second base 66, which serves as a cover. When the second base 66 is placed on the first base 64 and positioned accordingly, the tabs 156, especially those with penetrating tips 158, can sink into the material of the filament 60 (or sink when heated). This provides an additional form-locking connection, especially in the circumferential direction 72 and the radial direction 70.

[0295] The arrangement includes at least forty filaments 60, and more particularly at least forty-six filaments 60, and more particularly at least fifty filaments 60, and more particularly at least fifty-six filaments 60. This results in a high brush count and enables effective seam cleaning with a long service life.

[0296] In the illustrated embodiment, at least twenty filament assemblies 138 are provided, and more particularly at least twenty-three filament assemblies 138, and more particularly at least twenty-five filament assemblies 138, and preferably at least twenty-eight filament assemblies 138. In particular, each filament assembly 138 includes a filament pair consisting of a first filament 140 and a second filament 142.

[0297] The brush tool 44 provided according to the invention, when used in conjunction with the seam cleaning machine 10, is particularly effective in removing weeds from seams. In particular, the brush tool 44 is used outdoors.

[0298] The brush tool 44 can be achieved with a relatively small thickness in the axial direction 68. This thickness is particularly less than 12 mm, preferably less than 11 mm, and especially less than 10 mm.

[0299] This results in greater versatility for seams, and it is also able to clean narrow seams, especially removing weeds.

[0300] It can use filaments with relatively large thickness (e.g., 3mm). This results in effective cleaning and a long service life.

[0301] Furthermore, a relatively large number of bristles 60 (e.g., fifty-six bristles 60) can be arranged on the brush tool 44. This effectively promotes good cleaning results and a long service life.

[0302] The provided brush tool 44 can be manufactured in a simple manner. The filament 60 is reliably held on the retaining disc composite 62 in a technically simple and efficient manner. This results in a long service life and simple manufacturability.

[0303] The brush tool 44 according to the invention can be made from a relatively small number of basic components. As mentioned above, it only requires three basic components: a first substrate 64, a second substrate 66, and a filament 60.

[0304] In one embodiment, for example, a first substrate 64 is provided with ribs 126 and tabs 152. Corresponding wires 60 are placed on the first substrate 64 between adjacent ribs 132, 134. Then, a second substrate 66 is placed as a cover.

[0305] Material-locking connections are established, especially by ultrasonic welding. (Alternatively or additionally, adhesive connections can also be used.)

[0306] In the circumferential direction, rib 126 and first-type tab 152 provide abutment surfaces for wire 60, and a material-locking connection is also possible therewith. In the axial direction, first bottom 92 and second bottom 98 provide abutment surfaces, and a material-locking connection is also provided therewith.

[0307] In the radial direction toward the center 74, the annular tab 94 provides a mating surface, wherein, in particular, the wire assembly 138 is materially locked to the annular tab 94 at its respective end (which is opposite to end 148).

[0308] The second type of tab 154, which is recessed into the wire 60, provides an additional shape-locking connection in the region of the rib 126.

[0309] The third type of tab 156 provides an additional shape-locking connection in the area of ​​the second base 66, which serves as a cover.

[0310] The “multiple fastening” of the wire 60 and the retaining disc composite 62 results in a long service life with simple manufacturability.

[0311] Brush tool 44 can be made in a simple way.

[0312] As described, a basic structure is manufactured, and ultrasonic welding enables a connection to be established to a certain extent "globally" between the first substrate 64 and the second substrate 66, as well as between the wire 60 and the substrates 64 and 66.

[0313] Alternatively or additionally, a material-locking connection can be achieved through adhesive bonding. For example, in injection molding processes, it is also possible to achieve the corresponding connection, particularly through encapsulation.

[0314] As described, additional shape-locking connections can be established by sinking into the material of the corresponding filament via the second type of splice 154 and via the third type of splice 156.

[0315] In the illustrated embodiment, the first retaining disc 56 and the second retaining disc 58, or the first base 64 and the second base 66, are separately manufactured components, and then connected to each other during the manufacture of the brush tool 44 (where the filament 60 is also connected).

[0316] Alternatively, the retaining disc composite may be a one-piece, and especially integral, component comprising a first retaining disc 56 and a second retaining disc 58 as regions, or a first base 64 and a second base 66. Such a retaining disc composite holding the filament 60 is, for example, manufactured in an injection molding process and hereby particularly integrally formed.

[0317] Figures 13 to 16 A corresponding embodiment of the brush tool 160 is shown in the figure.

[0318] The brush tool 160 includes a retaining disc composite 162, which is integrally formed and, in particular, manufactured by an injection molding process. Therefore, the retaining disc composite 162 is an injection-molded part.

[0319] The retaining disk complex 162 has a first substrate 164 (first retaining disk) and a second substrate 166 (second retaining disk) as regions.

[0320] The retaining disk composite 162 has recesses 170 spaced apart in the circumferential direction on an end side 168 (which has a columnar circumferential shape). These recesses 170 are oriented in the radial direction.

[0321] The filament assembly, particularly the filament pair 172, is arranged in the recess 170. This arrangement is, in principle, the same as that described above in conjunction with the first filament 140 and the second filament 142.

[0322] Ribs exist between adjacent filament assemblies (between adjacent filament pairs 172). Filament pair 172 has a first rib 174a and an adjacent second rib 174b (see...). Figure 16 The recesses 170 are positioned close to each other between the first rib 174a and the second rib 174b.

[0323] Rib 174 is integrally arranged on retaining disc composite 162.

[0324] The retaining disc composite 162 is provided with openings 176 located between adjacent ribs 174 and mating with respective filament assemblies (filament pairs 172). These openings 176 enable action on the respective filament assemblies through these openings during the manufacture of the brush tool 160. This will be described in detail below.

[0325] In the illustrated embodiment, the first substrate 164 has a first ring 178 including openings 176. These openings 176 are spaced apart from each other in the circumferential direction. As described above, at least one opening is arranged between adjacent ribs 174a, 174b, and in particular exactly one opening is located on the respective filament assembly.

[0326] Accordingly, the second substrate 166 is provided with a second ring 180 including an opening 176 (see Figure 15 ).

[0327] The openings 176 of the first ring 178 and the second ring 180 are aligned with each other in the axial direction 182.

[0328] The wires of the wire assembly between adjacent ribs 174 are provided with (at least one) raised portion 184 (see Figure 16 The raised portion extends in a circumferential direction transverse to the axial direction 162.

[0329] In particular, each filament of the filament pair 172 has a raised portion 184 facing the adjacent filament pair. Therefore, the raised portions 184 of the filament pair 172 point outward in the circumferential direction.

[0330] The ridges 184 are permanent. They are established via openings 176, which will be explained in more detail below.

[0331] In particular, the raised portion 184 abuts against the corresponding rib 174 as a side recess. This creates a shape-locking connection in the radial direction (transverse to the circumferential direction and transverse to the axial direction 182). This provides a shape-locking connection for the corresponding wire pair 172 on the retaining disc composite 162, which in particular serves as a supplement to the material-locking connection.

[0332] In the manufacture of the brush tool 160, in particular the retaining disc composite 162 is made by injection molding. For this purpose, a corresponding mold is used, which is shaped accordingly to the structure of the retaining disc composite 162.

[0333] The filament assembly (filament pair 172) is formed on the mold.

[0334] Then, the retaining disc composite 162 is produced in the injection molding process.

[0335] During the manufacturing process, the filament assembly (filament pair 172) is acted upon through the opening 176 via the corresponding part of the mold or via an additional mold, and permanent deformation of the filament can be performed, especially under heating, so as to produce the bulge 184 accordingly.

[0336] In particular, the mold element and the mating mold element act on their respective filament assemblies via the openings 176 of the first ring 178 and the second ring 180 to create permanent ridges 184 in the finished brush tool.

[0337] In one embodiment, the opening 176 has a funnel-shaped structure relative to the axial direction 182 and narrows toward the anchoring assembly 138. This facilitates, in particular, the insertion or removal of the aforementioned mold element / fitting mold element during manufacturing.

[0338] It is possible, through opening 176, to create a side recess for the wire assembly 138 on the retaining disc complex 162 and especially on the rib 174.

[0339] In the illustrated embodiment of brush tool 160, openings 176 are open and visible after brush tool 160 is manufactured. It is also possible, in principle, that these openings 176 may be closed.

[0340] In other respects, brush tool 160 has the basic structure and advantages described above in conjunction with brush tool 44.

[0341] It is also possible that the brush tool 44 has openings 176 through which ridges 184 are formed on the silk assembly 138.
