Definitions
- the invention concerns to an apparatus for a brushing device, which brushing device is intended for brush rings and which includes a shaft arranged for the said brush rings, and an axial locking profile fitted to the shaft to prevent the rotation of the brush rings.
- the invention also concerns an arrangement in a brushing device using brush rings, a set of brushes for the brushing device, and a method for changing the brushing mode in a brushing device.
- the user of the brushing device has typically their own set of device for the brush rings. It includes a shaft adapted to the brush rings, on which the brush rings are set axially. The setting takes place in such a way that the locking members of each brush ring, such as, for example a radial pin arranged on the inner circumference of the base part of the ring, coincides with a locking groove or similar locking profile of the shaft. As a result, the brush ring is not able to rotate relative to the shaft.
- the brushing device's user can also have a separate strip brush system, in addition to the brush ring.
- the brushing device's shaft is grooved, being often made as an aluminium profile, for example by extrusion.
- the strips are placed axially in the grooves formed in the shaft's circumference.
- end-locks are attached to both shaft ends. They hold the strips in place axially.
- the present invention is intended to create an apparatus, arrangement, set of brushes, and method, by which it is simple to change from one type of brush to the other, and in addition to create cost-effective brushing readiness for both brush types.
- the characteristic features of the apparatus, arrangement, set of brushes, and method according to the invention are stated in the accompanying Claims 1, 11, 14, and 15.
- the apparatus according to the invention is an adapter for arranging brush strips on a shaft intended for brush rings.
- the adapter includes an annular base part.
- the base part is arranged to be locked in circumferential direction from its inner circumference to the axial locking profile fitted to the shaft.
- the base part belonging to the adapter is equipped from its outer circumference with fits shaped like the base of the brush strip to receive the brush strips and to arrange them on a shaft intended for brush rings, using the adapter.
- the adapter can also be called an adapter ring. Its inner circumference is arranged to lock in circumferential direction to the shaft and the outer circumference has a fit corresponding to the brush strip's base, in order to receive brush strips. Together with several similar adapters, the adapters form an elongated attachment arrangement on the shaft, for example in the form of a groove space. A brush strip is to be fitted into it by threading it axially by its base.
- At least some of the adapters can alternate axially to extend in both directions, so that the effective length of the attachment points formed by them for strip brush element increases considerably when placing the adapters on the shaft opposite to the axially oriented protrusions. This lightens the construction. In addition, fewer adapters are needed.
- the adapters include opposing axial locking members as circumferentially oriented catch, to prevent the adapters' mutual rotation on the shaft.
- the invention also relates to an arrangement, which includes several adapters, and also a set of brushes, which includes a shaft and a group of strip brushes in addition to several adapters.
- the arrangement includes ends arranged to be attached to the shaft, to prevent the adapters, and thus also the brush strips attached to them, from coming off the shaft axially.
- Figures 1a - 1c show one example of the apparatus 10' according to the invention, for the brushing device 33, and even more particularly the brush 43 of the brushing device 33.
- Figure 9 shows an example of one brushing device 33.
- the brushing device 33 is intended for brush rings 31. It includes a shaft 20 arranged for the brush rings 31 ( Figures 8a and 8b ).
- an axial A locking profile 22 is fitted to the shaft 20 to prevent the brush rings 31 from rotating on the shaft 20.
- a brush ring 31 there is in turn one or more radial locking members 13'. It can be arranged to lock to the locking profile 22 formed for it on the shaft 20. These are shown, for example, in Figure 8a .
- FIGs 1a, 1b, and 1c show an example of an individual apparatus 10'.
- the apparatus 10' is more particularly an adapter 10 for arranging brush strips 50, 50' on the shaft 20 intended, i.e. adapted for brush rings 31.
- a schematic example of the brush strips 50, 50' is shown in Figures 3a, 3b , 7 , 8a , and 8b .
- An annular base part 12 can be said to belong to the adapter 10. Its side profile forms a closed circular ring.
- the base part 12 can be said to have an inner circumference 17 and an outer circumference 18.
- the adapter 10 can be arranged to lock by the inner circumference 17 of its annular base part 12 in the circumferential direction to axial A locking profile 22 fitted to the shaft 20.
- Figures 2b - 4a show an example of this locking and its creation.
- the adapter 10 is on the outer circumference 18 of its annular base part 12 equipped with fits 14 arranged in the shape of the base 54 of the brush strip 50, 50'.
- the fits 14 are arranged to receive the brush strips 50, 50' and in this way to be attached to the adapter 10, and even more particularly to its annular base part 12.
- the fits 14 are also to arrange the brush strips 50, 50', using the adapter 10, on the shaft 20 intended for the brush rings 31. This diversifies considerably the possibilities of using the shaft 20 intended for the brush rings 31.
- the adapter 10 includes a radial, i.e. radially oriented R locking profile 38 fitted to the base part 12 in its inner circumference 17.
- the radial locking profile 38 is fitted to the inner circumference 17 to lock the adapter 10 in the circumferential direction to the axial A locking profile 22 fitted to the shaft 20.
- the radial locking profile 38 can form one or more radial protrusions 13 fitted to the inner circumference 17 of the base part 12 shown for example in the case according to the embodiment.
- the protrusion 13 of the locking profile 38 can also be termed a retainer. In the embodiment shown, there are two protrusions 13, these being now on opposite sides of the inner circumference 17.
- the protrusion 13, more generally the radial locking profile 38 can be, for example, like BEELINE® brush rings (FI and EP patent referred to in the description of the prior art).
- the axial A locking profile 22 fitted to the shaft 20 is shown, for example, in Figures 2b - 4b and especially in Figure 2c , which shows the brush-ring 31 shaft 20 shown in Figures 2a and 2b without an adapter 10, seen from the end.
- the axial A locking profile 22 is formed of two elongated locking formations fitted to the shaft's 20 outer circumference 28.
- the locking formation is now formed of an axial A groove strip 23 in the longitudinal direction of the shaft 20.
- the groove strip 23 has a U-profile opening outwards from the shaft 20.
- the protrusion 13 lies between the arms 29 forming the U-profile, being in the space 37 formed between them.
- the fit 14 arranged in the shape of the base 54 of the brush strip 50, 50' is arranged to form a group of radial protrusions 15.1, 15.2 arranged in the circumferential direction of the outer circumference 18 of the base part 12.
- the annular base part 12 can thus also be lightened in this way.
- the protrusions 15.1, 15.2 are arranged consecutively on the outer circumference 18.
- a space 26 is now arranged between the protrusions 15.1, 15.2.
- the space 26 forms, with several similar adapters 10, a strip groove 24 acting as a groove space 19' arranged for the shaft 20, more generally, an attachment arrangement 19.
- the space 26 is arranged in the shape of the cross-sectional profile of the base 54 of the brush strip 50, 50'.
- the radial protrusions 15.1, 15.2 forming the fits 14 are arranged in pairs in the circumferential direction of the outer circumference of the base part 12 in the adapter 10. Pair formations can be implemented in several different ways. One way to arranged the pairs is to form the base part 12 in such a way that the adapter 10 is of its base part 12 arranged to extend axially. In other words, the base part 12 then has a deformed structure. One example of this is an axially A angularly zig-zag shaped base part 12. Then, when the adapters 10 are set on the shaft 20, their circumferentially facing contacts surfaces 27 ( Fig. 1c ) are on both sides alternately in contact laterally with the adjacent adapters 10.
- the adapter 10 on the opposite side then is without contact. Then in the case of the exemplary zig-zag-shaped adapter 10, the adapters 10 can together form honeycomb open places (the openings 42 in Fig. 4a ) on the shaft 20.
- the adapter 10 can include axial A displacements arranged in its base part 12, oriented alternately on opposite sides of the adapter 10 in its axial direction A. Straight portions 39 then remain between the displacements. From the outer surfaces 27 of the straight portions 39 the adapters 10 can be arranged against each other when they are installed on the shaft 20.
- the base part 12 of the adapter 10 is formed regularly in a straight line into a laterally bent construction. Its base part 12 is then arranged to protrude laterally at an acute angle of, for example 45°, from its base level. Thanks to the aforementioned arrangement, it is first of all possible to assemble the adapters 10 on the shaft 20 by stacking the consecutive adapters 10 on the brushing device's 33 shaft 20 alternately the right way round and the wrong way round with a circumferential alignment. A honeycomb structure formed by consecutive base parts 12, for example according to Figures 4a and 4b is then created.
- FIGS 4a and 4b show clearly a construction arranged in the axial A displacement formed using the adapter 10 and the honeycomb construction arranged to be formed of the shaft 20 between two consecutive adapters 10.
- the displacements in the base part 12 and the following subsequent straight portions 39 alternating from one side to the other are arranged to form a hexagon on the shaft 20 between the base parts 12 of the consecutively arranged adapters 10.
- radial protrusions 15.1, 15.2 are arranged opposite each other on the outer circumference 18 of the base part 12.
- the protrusions 15.1, 15.2 can then be in the circumferential direction of the base part 12 described above on each of its straight portions 39.
- the pairing of the protrusions 15.1, 15.2 is then implemented in such a way that each straight portion 39 has two protrusions.
- a space 26 is then formed between the paired protrusions 15.1, 15.2 arranged in the shape of the cross-sectional profile of the brush strip's 50, 50' base 54.
- the radial protrusions 15.1, 15.2 are arranged divergently also axially A in the circumferential direction of the base part's 12 outer circumference 18. This is caused by the lateral displacement in the base part 12. Then the protrusions 15.1, 15.2, which are in the base part 12 on consecutive straight portions 39, separate from each other circumferentially, are on slightly different lines relative to each other axially A. On the other hand, then too the protrusions 15.1, 15.2 can be said to be paired, but now also axially A.
- a circumferential space 26 forms between the protrusions 15.1, 15.2 on the consecutive straight portions 39, arranged in the shape of the cross-sectional profile of the brush strip's 50, 50' base 54.
- the protrusions 15.1, 15.2 delimiting the space are slightly displaced axially A due to the alternating shape of the base part 12.
- a circumferential semi-profile 40 of the base 54 is then arranged, relative to the space 26 arranged in the shape of the base 54 of the brush strip 50, 50' on the opposite side of the base part 12, in the radial protrusions 15.1, 15.2 to form the space 26 formed in the base 54 with the second protrusions 15.1', 15.2'.
- the second protrusions 15.1', 15.2' can thus be, for example, radially divergent.
- the formations 41 are circumferential claws 41.1, 41.2 fitted to the protrusions 15.1, 15.2. They permit the brush strips 50, 50' to be threaded axially A into the spaces 26 formed between the protrusions 15.1, 15.2.
- the formations 41 can vary greatly between different manufacturers of the brush strips 50, 50' and even between the same manufacturer's different brush-strip models.
- the adapter 10 includes axial locking members 16, 11 fitted to opposite sides of the base part 12, now as a circumferential safety catch. According to one embodiment, this can be implemented with the aid of axial pins 16 arranged in the adapter 10 and corresponding holes 11 fitting to the pins 16, when the adapters 10 are assembled consecutively on the shaft 20, for example according to Figures 2a , 4a , and 4b .
- the adapters 10 axially in a cluster are firmly secured on each other against rotation.
- the adapters 10 to be handle in clusters of several adapters 10.
- the locations of the pins 16 and holes 11 in the flat surfaces 27 facing the sides of the adapter 10 provide a guide to the correct orientation and support of the adapters 10 when they are installed on the brushing device's 33 shaft 20.
- the invention also relates to an arrangement in a brushing device 33 using brush rings 31.
- the arrangement is described in greater detail with reference to Figures 2a - 4b . This will also clarify the arrangement of the adapter 10 and the shaft 20 relative to each other.
- the arrangement includes a shaft 20 for brush rings 31, which shaft 20 includes an axial A locking profile 22 to prevent the rotation of the brush rings 31.
- the arrangement includes several apparatuses 10', i.e. adapters 10 according to the invention.
- the adapters' 10 inner circumference 17 is arranged to lock onto the shaft 20 in the circumferential direction and on the outer circumference 18 there is in turn a fit 14 corresponding to the brush strip's 50, 50' base 54 for receiving the brush strips 50, 50' in an elongated attachment arrangement 19 formed of several adapter rings 10, which can be, for example, the described elongated groove space 19'.
- the adapters 10 are arranged to form together an elongated groove space 19' to receive the brush strips 50, 50' by their base parts 54.
- the attachment arrangement 19 can equally also be an elongated attachment rail (not shown) formed by a radial protrusion of the adapter 10.
- the axial A cross-sectional profile of the radial protrusion is then adapted to the shape of the brush strip's base.
- a shape-locking male-female joint pair between the brush strips and the adapter's 10 outer circumference 18 can be formed both towards the base 54 and the adapter 10.
- an adapter element 30 is created that is arranged to receive and attach a brush strip 50, 50' in connection with the shaft 20.
- the adapter element 30 is preferably assembled by placing the axial extending, i.e. protruding base parts (34, 34 and correspondingly 32, 32) against each other. Using this light, but quite sturdy construction the entire axial A length required to attach the brush strip 50, 50' is created. In other words, the axial A length of a single adapter 10 is only a fraction (a few centimetres) of the axial A length (about one metre) of the entire brush strip 50.
- the adapter's 10 axial A effective or the width covered on the shaft 20 can be, for example, 2 - 15 %, more particularly 2 - 10 %, and even more particularly 2 - 5 % of the brush strip's 50 axial A length. This facilitates the handling of the adapters 10 and lightens the construction.
- FIG. 11 shows this arranging of the adapters 10 against each other when assembling them.
- the adapter elements 30 are quite light to handle even when equipped with brush strips 50. For example, their length can be 1 m.
- Several adapter elements 30 can be made ready for brushing operations. They then only need to be installed when required on the shaft 20. The assembled adapter element 30 together with the installed brush strips 50 is easily threaded onto the shaft 20.
- the adapter 10 being fitted by its base part 12 to extend axially, its effective length also increases as a brush strip 50, 50' attaching element. This is realized if when installing the adapters 10 they are arranged axially A in such a way that the adapters' 10 protrusions 32, 34 are opposite each other.
- the arrangement includes end stops 36.
- the end stops 36 are arranged to be attached to the shaft 20.
- the end stops 36 are arranged to prevent the adapters 10 and also the brush strips 50, 50' arranged on them from moving axially A, i.e. coming off the shaft 20.
- Figure 2a shows the end stop 36 at the left-hand end of the shaft 20. In this way, the brush strip 50, 50' and also the adapters 10 are made to remain in place axially A.
- the end stop 36 also presses the adapter clusters against each other.
- the adapters 10 are installed on the shaft 20.
- shaft 20 there is an external groove strip 23 on its outer circumference 28 on the opposite sides of the shaft 20 and also end plates 36, in which is a centre hole 35 for the brushing device's 33 shaft pin. Through it the brush 43 is rotated.
- Figures 3a and 3b show the attachment of brush strips 50 to an adapter element 30 formed of adapter rings.
- the brush strips 50 there are radial bristles 52 set in an as such known manner, which are attached to a base part 54.
- the base part 54 is a strip profile shaped in a chosen manner. It can equally also be a groove profile.
- the adapters 10 are always adapted to a specific strip profile or to a groove profile. Of course, in some cases there could also be a universal fit 14 in the adapter 10. Several strip profiles could then be used in it. It would even be possible to function without a radial protrusion in some cases.
- the base part 12 of the adapter 10, in which a fit 14 for the brush strip 50 is formed, can then be utilized directly.
- Figure 3b shows especially clearly the setting of an end stop 36 into the bases 54 of the brush strips 50.
- Another feature is the positioning of the axial A element belonging to a U-rail 23 fitted to the outer circumference of the shaft 20, more generally to the locking profile 22, to the inner circumference 17 of the adapters 10 and to the protrusion 13 acting as a radial retainer fitted to it.
- Figures 4a and 4b show the assembly of adapter rings 10 on the shaft 20.
- Figure 4b also shows the radial direction R.
- the formation of the groove space 19' in the circumferential direction of the shaft 20 can vary, for example, alternately.
- Every second groove space 19.1 is then arranged to be formed radial protrusions 15.1, 15.2 arranged opposite each other on their outer circumferences 18 axially A in the apparatuses 10'.
- Every second groove space 19.2 is arranged to be formed of radial protrusions 15.1, 15.2', 15.1', 15.2 arranged to differ axially A on the outer circumferences 18 of the apparatuses 10'.
- the groove space 19' can be implemented using a very light structural solution, for example compared to the groove space forming continuously a strip groove 24 on both sides in the axial direction A.
- Figures 5a - 5c show a second embodiment of the adapter 10.
- the adapter 10 is a planar, i.e. straight circular ring in the axial A direction of the base 12. This can be clearly seen, especially in Figures 6a and 6b .
- the radial locking profile 38 fitted to the adapter's 10 base part 12 includes at least two radial protrusions 13.1, 13.2 arranged to act as locking members to be fitted to the shaft's 20 locking profile 22.
- the protrusions 13.1, 13.2 are now consecutively adjacent in the circumferential direction. They can said to be in pairs. Here they are mainly in the form of radial pins.
- the radial protrusions 13.1, 13.2 are thus used to arrange, an optional, i.e. changing, circumferential position to attach the adapter 10 to the shaft 20.
- the protrusion arrangement is dimensioned in such a way that the U-rail 23 of the shaft 20 lies tightly against either protrusion 13.1, 13.2.
- the protrusions 13.1, 13.2 can be inside the U-rail 23 in turns. They can then lean on, for example, the inner edge of the edge 29 delimiting the space 37 of the rail 23.
- one of the protrusions 13.1, 13.2, for example the second can also lean on the outer edge of the edge 29 of the U-rail 23.
- Both of the protrusions 13.1, 13.2 now also have counter-pairs 47.
- the counter-pairs 47 are in edges of the pairs formed by the protrusions 13.1, 13.2 in the circumferential direction. In the embodiment described the protrusions 13.1, 13.2 remain between them.
- the counter-pairs 47 ensure that the protrusions 13.1, 13.2 remain in the U-rail 23, more generally, in the locking profile 22.
- the distance between the protrusion 13.1, 13.2 and the counter-pair 47 arranged for it is arranged in such a way that a small groove, into which the edge 29 fits, remains between them. This further ensures the locking.
- the counter-pair 47 which is on the side of the protrusion, which is not locked to the groove, can for its part lean on the outer circumference 28 of the shaft 20, as shown in Figures 5b and 5c . This too reduces the strain acting on the adapter 10.
- Figures 6a and 6b show two possible positions of the adapter 10 around the shaft 20, which is shown in Figures 5a - 5c .
- this embodiment diversifies the arrangement created, in that by using the same adapter 10 and brush strips 50, for example, from a strip brush 43 formed of six strips in the axial direction A, either six strips in the same axial line, or then overlapping are obtained. By overlapping, six different sectors are obtained. This increases the bushiness of the strip brush.
- the adapter 10 includes axial locking members 16' fitted on opposite sides of the base part 12. They can act, once again, for example, as a circumferential check, but now also in addition to, or instead of a gap being arranged between the adapters 10.
- the base 12 of the adapter 10 is a straight ring.
- pins 16' on its laterally oriented contact surfaces 27, by which not only the locking can be ensured, but now also the distance between the adapters 10.
- the structure is thus lightened.
- the protrusions 15.1, 15.2 in the base 12 are now circumferentially consecutive. Spaces 26 are formed between them for the brush strip's 50 base 54. Thus, the spaces 26 are formed by the protrusions 15.1, 15.2 in pairs on both sides of the outer circumference of the base 12.
- the adapters 10 form partial elements, unlike what is shown in Figures 4a and 4b .
- the partial elements are installed on the brush's 43 shaft 20 being formed axially A on a slightly different line to each other.
- Figure 7a shows the assembly of the partial elements on the shaft 20.
- One way to achieve this is to first of all arranged the adapter rings in partial assemblies 30.1 - 30.3, ..., 30.n. Then the partial assemblies formed 30.1 - 30.3, ..., 30.n are installed mutually so that the middle one is turned by 11.25° relative to the others. This describes how "bushiness" is created for the brush totality through the partial assemblies.
- the number of strips in the circumferential direction of the shaft 20 can be other that described in this case (16).
- the mutual angle of the partial assemblies then also changes.
- the adapter 10 is a complete integral piece. In other words, the fits 14 for the brush strips 50 and the locking profile 38 are both in the same annular base part 12.
- the adapter 10 is typically of a single material and is made, for example, from plastic, composite, or metal (e.g. aluminium).
- One example of a way of making the adapter 10 is moulding, such as, for example injection moulding.
- An aluminium adapter 10 can be made, for example by die-casting.
- the adapter 10 has the properties of a hard and also rigid piece.
- the adapter 10 is also a low structure in the radial direction R. In other words it does not significantly increase the shaft's 20 diameter.
- the shaft's 20 diameter can be 7 - 10 inches.
- the adapter 10 only increases the diameter by a few tens of millimetres, such as, for example 50 mm.
- the same brushing device's 33 shaft 20, in which brush rings 31 are used can, with the aid of adapters 10 be converted to use a brush strip 50, 50'.
- This is an economical solution to use, on the same shaft 20, either brush rings 31 or brush strips 50, or even simultaneously, as shown in Figure 8b , brush rings 31 and brush strips 50. It also does not demand changes to the brushing device 33 itself. Changing the brush elements 25 is also quick, so that it saves time and bother.
- the invention also further relates to a set of brushes for a brushing device 33.
- Figure 8a shows an example of this.
- the set of brushes 21 includes brush elements 25 and a shaft 20 equipped with a locking profile 22 for brush rings 31.
- the brush elements 25 are exchangeably to be assembled on the shaft 20.
- the set of brushes 21 includes several brush strips 50, 50'.
- the set of brushes 21 also includes several apparatuses 10' according to the invention for arranging brush strips 50, 50' on the shaft 20 of a brushing device 33 adapted for brush rings 31.
- Figure 8a also shows an example of a radial locking member 13' fitted to the base part of a brush ring 31.
- the adapter 10 and an element 30 assembled of them on a shaft 20 is product that can be used for a long time.
- the brush strips 50 are worn out, they are detached from the element 30 formed of adapters 10 by opening the end flange 36. After this, the worn brush strips 50 are pulled off the element 30 and thus also the shaft 20, to which they are rotatably attached through the element 30 and new brush strips 50 are pushed in their place.
- the end flange 36 is reattached and brushing can continue with the strip brush thus formed.
- Figure 9 shows an example of a brushing device 33, in which the invention can be applied.
- the brushing device 33 is attached, for example, to the lifting mechanism 44 of a work machine 45.
- the brushing device 33 can then be used to brush the surface 46 on which the work machine 45 moves, such as, for example, streets and areas.
- the adapters 10 and the one or more elements 30 to be formed from them on the shaft 20 are used, for example, as follows:
- the adapters 10 according to the invention can be implemented for all brushing devices 33 and even more particularly for all of their shafts 20.
- the sizes of the adapters 10 can cover all the shaft sizes and models.
- the number of brush strips 50 can vary of shafts 20 of different sizes.
- the model and shape of the brush strip 50 also affect the number of brush strips 50.
- One example of the base's 54 profile appears in Figure 8a .
- the invention need not of course be restricted to the base-profile example shown.
- the adapter elements 30 there are claws 16, 16', which attach them to each other. However, the elements 30 can be detached from each other if necessary. The claws 16, 16' also position them at the correct alignment to each other. The brush strips 50 can then be easily set in the grooves 24 in them. The locking claws 16, 16' also permit the adapter elements 30 to be handled as a totality / partial totality.
- planar surfaces 27 there are also planar surfaces 27 in the adapter elements 30. Thanks to the planar surfaces 27 the elements 30 lie parallel to each other on the shaft 20.
- the adapter's 10 inner circumference 17 has a locking profile 38, such as, for example a protrusion 13, which can also be called a rivet.
- the locking profile 38 can be used to set the adapters 10 in the same attitude on the shaft 20.
- the adapter elements 30 have various rivet alternatives. They then fit different shafts 20.
- the shape of the adapters 10 permits then to be packed in a small space for transportation. This reduces their transport costs and thus also their carbon footprint.
- the adapters' 10 shape also reduces the number of them on the brushing device's 33 shaft 20, which brings savings in many different ways.
- the adapters 10 can be set on the shaft 20 at two or more different angles, when the brush strips 50 are "overlapping". This means that, for example, 0.5-m long brush strips 50 are in two different attitudes over the entire length of the shaft 20. In this way it is possible to imitate brush strips in a spiral shape, but it also permits softer operation during brushing.
- the invention also relates to a method for changing from one brushing mode to another using the brushing device 33.
- the brushing modes are brushing performed using a brush assembled from brush rings 31 on a shaft 20, i.e. ring brushing, and brushing performed using a brush 43 assembled from brush strips 50 on a shaft 20, i.e. strip brushing.
- the brush 43 can also be called a brush roll.
- a set of brushes 21 according to the invention is used in the method.
- both brushing modes are performed using the same shaft 20 intended for brush rings 31.
- the solution according to the invention also creates a low threshold to seek experience of brushing using a strip brush, if it is compared, for example, to the acquisition cost of a separate special strip-brush shaft, which can be as much as € 1000 - 2000.
