Description

The present invention relates to a carrier for a circular comb of a combing machine, and a circular comb with such a carrier.

Such supports for circular combs are used for combing machines for combing out a submitted fiber mass (cotton, wool, etc.), the submission of the fiber mass being in the form of wadding webs wound on sleeves or in the form of individual slivers. The numbers of nips (nips/minute) have increased significantly in recent years, which also brings with it an increase in productivity.

The circular combs used for the combing machine in practice consist of a circular comb carrier, which is provided with a clamping hub with which it is non-rotatably attached to a driven circular comb shaft. A combing segment is fastened to a partial circumference of the circular comb carrier, with which the end of the fiber mass (also called fiber tuft) presented by a nipper unit is combed out. In an alternative embodiment, circular comb carriers are used, which are applied to a support body, the support body in turn being held on a driven circular comb shaft.

The requirements for such a circular comb and thus for the wearer have been increased, e.g. B. when the circular comb no longer has a continuous speed, but is driven with a discontinuous rotary motion in order to better adapt the system to the combing process. This discontinuous movement places high demands on the drive of the circular comb and the construction of the carrier, particularly when the relatively large mass of the circular comb has to be accelerated or decelerated.

In the EP-2 426 239 A1 an embodiment of a circular comb has been proposed which improves known solutions and the circular comb has a lower mass moment of inertia than previously known solutions. It is suggested that the carrier consists of a hollow profile, which has an outer circular arc-shaped section for accommodating the combing set and with an inner section opposite this, with a semicircular trough open in the direction of the shaft, which extends in the longitudinal direction of the hollow profile and over which the carrier extends supported on a shaft. In this way, the mass and thus the mass moment of inertia of the carrier can be kept low.

However, it has been shown that with the in the EP-2 426 239 A1 The solution shown, the arc-shaped trough with which the hollow profile is supported on the circular comb shaft is complex to process, so that a perfect support of the hollow profile is guaranteed on the circular comb shaft and it does not lead to tension. In addition, it is difficult with this embodiment to vary or adjust the distance between the enveloping circle of the combing assembly and the circular comb axis. With such an adjustment, the distance between the lower nipper plate of the nipper and the enveloping circle of the combing assembly of the circular comb can be adjusted in order to ensure optimum combing. Such adjustability through the use of an arcuate spacer element z. B. in the DE 297 20 656 U1 shown and described. However, an exact adjustment option down to the smallest increments is not possible with such a curved element. If, for example, to change the radius of the enveloping circle of the combing of the circular comb, in which DE 297 20 656 U1 If the arcuate spacer element shown is exchanged for another arcuate spacer element with a different thickness, the outer radius of the spacer element projecting in the direction of the carrier changes, while the inner radius of the carrier with which it rests on the spacer element remains constant. As a result, tension can arise between the carrier and the spacer element.

Next revealed the EP 2 789 716 A1 a circular comb with a carrier, which is provided with an inner section protruding towards the shaft, which has a depression which is open towards the shaft and extends in the longitudinal direction of the hollow profile, in which a support element is accommodated, which extends on the one hand via a first Support surface on a base of the recess and on the other hand supported on a second support surface on the outer circumference of the shaft. Here are between the support element and the base of the recess provided interchangeable spacer elements. This should make it possible to set the radius of the enveloping circle of the combing clothing exactly by simply inserting precise spacer elements between the base body and the support element. The disadvantage, however, is that an adjustment of the distance between the lower nipper plate of the nipper and the enveloping circle of the combing assembly of the circular comb can only be changed step by step depending on the existing spacer elements. In addition, the circular comb must be removed from the combing device for readjustment of the distance in order to be able to exchange the spacer elements.

The object of the present invention is therefore to create a support for a circular comb which enables continuous adjustment of the distance between the lower nipper plate of the nipper and the enveloping circle of the combing assembly of the circular comb, with the setting being able to be changed without removing the circular comb.

The object is solved by the devices with the features of the independent patent claims.

Proposed is a carrier for a circular comb of a certain length of a combing machine with a clothing support surface and at least one support surface opposite the clothing support surface, the clothing support surface and the support surface being arranged in a concentric circular shape around a circular comb axis in a cross-section viewed perpendicular to the length. The support surface is formed on a central profile and the clothing support surface is connected to the central profile. At least one first pair of spring ribs is arranged on the central profile to support the carrier on a circular comb shaft or on a support body, with the spring ribs of the first spring rib pair each having a support facing the circular comb axis at an end facing away from the central profile, so that the spring ribs when the carrier is mounted on the Round comb shaft or on a support body are correspondingly deflected.

The carrier essentially consists of a central profile, a clothing support surface provided on or attached to the central profile and also on the central profile spring ribs attached in pairs. The combing clothing is attached to the clothing support surface with suitable means, for example with screws, by welding or gluing. Comb sets consisting of individual wire strips applied to the clothing support surface or also comb sets consisting of prefabricated combing elements which are applied to the clothing support surface are used here. The clothing support surface is arranged in the shape of a segment of a circle around a circular comb axis. The at least one support surface is provided on the side of the central profile facing away from the clothing support surface; this can be formed on the central profile. The support surface is designed as an arcuate depression with a radius of 25 mm to 90 mm, corresponding to a conventional round comb shaft. In an alternative form, the support surface is designed as an arcuate depression with the radius of 80 to 150 mm corresponding to a conventional support body.

The spring ribs are embodied as ribs with one end pointing freely into the space against the circular comb axis or into the space below the support surface. At the ends of the spring ribs there are supports which are brought into contact with a maximum deflection when the support surface rests on a surface of a circular comb shaft located in the circular comb axis or on a surface of a support body held on the circular comb shaft. The distance of the respective support from the circular comb axis is therefore identical to a radius of the support surface. When the carrier is mounted on the crested shaft, the spring ribs are correspondingly deflected by the surface of the crested shaft. The intended supports on the spring ribs can be provided as actual straight or arcuate surfaces. A convex shape of the ends of the spring ribs is also to be understood as a support within the meaning of the application. With a convex design of the ends of the spring ribs, the spring rib rests linearly on the surface of the crested shaft when it rests against the crested shaft.

In an advantageous embodiment, the clothing support surface is attached to the central profile or is part of the central profile. This has the advantage of being low and compact design of the carrier results and this can be attached to conventional support bodies.

In an alternative advantageous embodiment, the clothing support surface is connected to the central profile via at least two struts. Up to six struts are preferably provided, as a result of which greater stability can be achieved. With such a design of the carrier, the distance between the support surface and the clothing support surface can be chosen such that no support body is required between the carrier and the circular comb shaft and the carrier can be attached directly to the circular comb shaft. The number of struts between the clothing support surface and the central profile is dependent on the size of the circle segment which must be occupied by the combing clothing.

The struts and the spring ribs advantageously have a first common section, starting from the central profile. This results in a more stable support of the outer areas of the clothing bearing surface on the circular comb shaft with a large circumferential angle of the clothing bearing surface. Accordingly, the central profile can be made narrower, which has further advantages in reducing the mass of the carrier.

The spring ribs are preferably divided by at least one bend into a first element section and a second element section in their course from the central profile to the support, with the first element section and the second element section enclosing a spring angle of 50 to 90 angular degrees. As a result of this design, the spring rib is not deformed as a whole by forces applied to the support surface, but is mainly changed in its spring angle. The spring ribs can also be bent several times at an angle between the central profile and the support, with the entire change in direction always being seen as the spring angle. As an alternative to a kink, the spring ribs can also be bent at a specific radius. Particular advantages result from this construction of the spring rib if a first element section is also used as part of a strut between the clothing support surface and the central profile. Is that the case A deformation of this element section is to be avoided in order not to transfer a deformation of the spring rib to the clothing support surface.

It is also advantageous if the clothing support surface is connected to the central profile by two to six struts. If several struts are provided between the clothing bearing surface and the central profile, this results in a more rigid construction and dimensional stability of the clothing bearing surface can be guaranteed even with high acceleration forces. Influencing the dimensional stability of the clothing contact surface through the deformation of the spring ribs is also ruled out.

Up to six spring ribs are preferably arranged in pairs on the central profile and are arranged symmetrically in relation to the support surface to support the carrier. This allows the spring load to be distributed over several spring ribs. In addition, there are a corresponding number of support surfaces on the circular comb shaft or the support body, which result in lower surface pressure on the circular comb shaft or the support body and also a more stable mounting of the carrier.

The spring ribs arranged on one side of the central profile preferably have a common connection point on the central profile in an embodiment of the carrier with direct bearing on the circular comb shaft. The various spring ribs can also be connected to the struts via common element sections. The common connection point on the central profile results in an even load on all spring ribs.

As is known from the prior art, the carrier can be provided as a disc with a specific length, the length being seen in the direction of the circular comb axis. The length of the carrier corresponds to only a fraction of the length of the circular comb, with several such short carriers being used to fasten the combing set. The use of several carriers for a combing set has the disadvantage that an alignment of the carrier is complex in order to achieve a concentric arrangement of the combing set with respect to the circular comb shaft. The length of the carrier therefore advantageously corresponds to a length of the circular comb. This has additional the advantage that the circular comb can be pre-assembled with the combing set before it is installed in a combing machine. In order to obtain the lowest possible mass of the carrier with an extremely simple construction, the carrier is produced as a hollow profile by continuous casting. This makes it possible for the struts and the spring ribs to have a longitudinal extent corresponding to the length of the circular comb, as a result of which greater spring forces can be absorbed via the spring ribs. The supporting surface as well as the supports of the spring ribs or the clothing support surface do not have to be guided over the entire length. The surfaces can be alternately interrupted and formed, for example, over 50 percent of the length of the circular comb. In a particularly preferred manner, however, the support surface as well as the supports of the spring ribs and the clothing support surface are formed over the entire length of the carrier.

Advantageously, the supports of the spring ribs are arranged concentrically to the support surface, with an enveloping circle of the supports having a smaller radius than the support surface. As a result, the spring ribs are deflected during assembly on the circular comb shaft or the supporting body and the carrier is pressed away from the circular comb shaft or the supporting body under the bending force of the spring ribs. In order to achieve such tension, it would also be conceivable to correspondingly shape the surface of the circular comb shaft or the support body at the point at which the supports of the spring ribs rest.

Furthermore, a combing device with a circular comb and a balancing weight is proposed, the circular comb having a carrier with a clothing support surface. The carrier and the counterweight are mutually arranged on a crested shaft and clamped together with fastening elements through the crested shaft. The carrier has a central profile with a support surface opposite the clothing support surface and at least a first pair of spring ribs consisting of one spring rib each on both sides of the support surface, with the spring ribs each having a support at an end facing away from the central profile to support the carrier on the circular comb shaft. The design of the supports can be adapted to the surface of the comb shaft. Basically is However, a support is not to be understood as a surface in the sense of a plane, but rather as a defined shaping of the end of the spring rib. A flat as well as a circular, concave or convex shape can be selected. It is important that the support is designed in such a way that the spring rib rests evenly on the surface of the circular comb shaft over the length of the spring rib. Due to the spring ribs of the carrier resting on the circular comb shaft, a stable attachment of the carrier is made possible even with a narrow support surface on the central profile.

In an alternative embodiment, a combing device with a circular comb and a balancing weight is proposed, the circular comb having a carrier with a clothing support surface and a support body. The support body and the counterweight are mutually arranged on a crested shaft and clamped together with fastening elements through the crested shaft. In this case, the carrier is fastened to the support body with fastening elements. The carrier has a central profile with a support surface opposite the clothing support surface and at least one first pair of spring ribs, the spring ribs each having a support at an end facing away from the central profile to support the carrier on the support body. The advantage of this design is that existing designs of combing devices that have a support body in their design can be retrofitted with an advantageous carrier as described above without having to replace the existing combination of support body and compensation element.

Advantageously, when the support surface rests on a surface of the circular comb shaft or a surface of the support body, the spring ribs with their supports on the surface of the circular comb shaft or the surface of the support body are brought into contact under maximum tension. When the carrier is fastened to the circular comb shaft or the support body, the support surface of the carrier serves as a stop, as a result of which the approach of the carrier to the circular comb shaft or the support body is stopped when this stop is reached. Thus, when the stop is reached, further deformation of the spring ribs is no longer possible and due to the Contact between the supports and the surface prevents overstretching of the spring ribs. The fastening of the carrier also corresponds to a setting of the maximum distance between the lower nipper plate and the enveloping circle of the comb clothing located on the carrier when the support surface rests on the circular comb shaft. If the fastening is now released by unscrewing the fastening screws, the carrier and thus the circular comb are lifted off the circular comb shaft or the supporting body by the spring ribs and a gap forms between the supporting surface and the surface of the circular comb shaft or the supporting body. At the same time, the distance between the lower gripper plate and the enveloping circle of the combing clothing is reduced. However, the spring ribs continue to ensure a stable attachment of the carrier and thus of the circular comb on the circular comb shaft or the support body.

With a corresponding design of the spring ribs, these are brought into contact with their supports on the surface of the circular comb shaft or the support body under such high tension that an adjustment of the distance between the lower nipper plate and the enveloping circle of the comb set located on the carrier or the Gap between the support surface and the surface of the circular comb shaft or the support body of 0 mm to 1.5 mm can be achieved. Preferably, the gap should be adjusted to 0.8 mm when using the circular comb in high-performance combing machines. By loosening or tightening the fastening of the carrier on the circular comb shaft or on the support body, the distance between the lower nipper plate and the enveloping circle of the combing set on the carrier can be easily adjusted without the circular comb having to be removed from the combing device when the setting is changed . A setting can thus also be checked directly in the installed state by measuring the distance between the lower gripper plate and the enveloping circle of the combing set on the carrier. For this purpose, the combing device can be rotated into a measuring position in the installed state, in which the distance can be adjusted and measured.

Furthermore, it is advantageous if the counterweight is held non-rotatably on the circular comb shaft with fastening elements, independently of the carrier. This makes it possible to replace the carrier without having to remove the counterweight from the circular comb shaft.

It is also advantageous if, independently of the fastening elements for bracing the carrier with the balancing weight, a force transmission element is provided between the carrier and the comb shaft for transmitting the acceleration forces from the comb shaft to the carrier. An additional force transmission element is provided in order to avoid a high load on the fastening elements or the spring ribs caused by the acceleration forces that occur. The acceleration forces are created by superimposing a base speed with a sinusoidally increasing and decreasing speed. This type of movement is necessary to optimize the entire combing process. The forces which occur as a result of the acceleration of the rotational speed of the circular comb shaft with each revolution are transmitted by the force transmission element from the circular comb shaft to the carrier, as a result of which the spring ribs are correspondingly relieved.

Advantageously, the power transmission element is designed as a bolt which has an internal thread and has a surface formed on the circular comb shaft in an end region. The bolt is braced against the circular comb shaft with a threaded bolt that extends through the circular comb shaft. In addition, the bolt is provided with an O-ring for fixing the bolt in a hole in the carrier. Such a bolt contributes nothing to the bracing of the carrier on the circular comb shaft but is only intended to take over the acceleration forces. The carrier is freely movable in the direction of a longitudinal axis of the bolt. As a result, the spring ribs and the fastening elements of the carrier are largely relieved of transverse forces that occur. This relief allows a reduction in the number of fasteners provided today. To brace a round comb, only two fastening screws can be used instead of four fastening screws. This leads to an easier assembly and to a user-friendly setting of the circular comb. The use of O-rings allows the bolts to be used without play, which counteracts wear and tear on the spring ribs due to the occurring acceleration forces due to a reversal of the direction of the occurring forces. The bolts also do not fall out of the bores when dismantling the round comb thanks to the use of O-rings. Another positive aspect is that when the carrier is dismantled, the bolts can remain on the round comb shaft, which means that the carrier can be correctly positioned when it is inserted.

A combing machine with at least one combing device according to the above description is also proposed.

figure 1 shows a schematic side view of a combing head 1 of a combing machine according to the prior art. In known combers z. B. eight such combing heads 1 arranged side by side. The combing head 1, of which only a part of the elements is shown, has a nipper unit, which is mounted on the swivel arms 3 and 4 about the nipper shaft 5 and the circular comb axis 6 and can be swiveled back and forth in the frame of the combing machine. The tong shaft 5 is driven by a drive, not shown in detail, in order to give the tong unit a reciprocating movement. In the circular comb axis 6, the circular comb shaft 8 is arranged, on which a circular comb 7 is fixed in a rotationally fixed manner. The circular comb shaft 8 with its circular comb axis 6 is also driven continuously or discontinuously in the direction of rotation 23 by a drive (not shown). In the known solution shown, the circular comb 7 fastened below the pliers unit on the circular comb shaft 8 consists of two hubs 9 fixed fixedly to the circular comb shaft 6 at a distance from one another, on the outer circumference of which a base body 10 on the one hand and a counterweight 11 on the other are fastened. As shown schematically, the counterweight 11 is attached by means of the screws 12, by means of which the counterweight 11 is attached to the hubs 9. The base body 10 is also firmly connected to the hubs 9 by means of screws shown schematically. Above the base body 10, which, like the counterweight 11, extends over the entire length L (see FIG. 4) of the circular comb 7, a combing set 13 is attached. The circumferential angle of the combing clothing 13 is about 90 degrees in known combing machines and is also referred to as the "combing angle".

The tong unit is formed from a tong frame 14 to which a lower tong plate 15 and an upper tong plate 16 is attached. In the embodiment shown, the nipper unit is closed, with the fiber tuft 17 protruding from the clamping point of the nipper unit being seized and combed out by the combing set 13 . The combing out is essentially determined by the distance C between the lower gripper plate 15 and an enveloping circle 2 of the combing clothing 13 . Also in the tong frame 14 a feed roller 18 is rotatably mounted above the lower tong plate 15, which z. B. is driven step by step by a ratchet drive, not shown. A batting 19 (or individual slivers) fed to the combing device 1 is fed to the clamping point of the gripper unit via this feed roller 18 . After the tuft 17 has been combed out, the nipper unit is pivoted in the direction of a subsequent pair of detaching rollers 20 . During this pivoting process, the gripper unit opens and the combed-out end of the wadding 19 or the fiber tuft 17 is placed on the end of a previously formed fiber fleece 21 and soldered to it under the action of the clamping point of the detaching rollers 20 and transported away in the conveying direction 22.

figure 2 shows a schematic representation of a first embodiment of a carrier 24 according to the invention in cross section. The carrier 24 has a central profile 28 and a granite bearing surface 26 . The clothing support surface 26 is adapted to the nature of the combing clothing (not shown) to be fastened thereon. In the present example, the clothing support surface 26 extends over a combing angle α in an arc around a circular comb axis 6. The circular comb axis 6 serves as a reference point for the entire carrier 24. On a side of the central profile 28 opposite the clothing support surface 26, there is a support surface on the central profile 28 27 trained. The support surface 27 is designed concentrically to the clothing support surface 26 with a radius adapted to the circular comb shaft (shown in broken lines).

The clothing support surface 26 is supported on the central profile 28 via first struts 29 and second struts 30 . A pair of spring ribs 31 is provided to support the carrier 24 on a crested shaft. The struts 29 and 30 and the spring ribs of the pair of spring ribs 31 are each arranged in pairs and symmetrically to the central profile 28 . The first struts 29 each have a section 34 that is common to a spring rib 31 . The spring ribs 31 are formed on the central profile 28 via the common section 34 . In the further course, the spring ribs 31 are divided into a first element section 35 and a second element section 36, with the first element section 35 and the second element section 36 enclosing a spring angle β. The formation of the spring ribs 31 in their course of the element sections 35 and 36 can have further bends and radii. For example shows figure 2 an additional bend in the element section 35. However, this is not decisive for the determination of the spring angle β. Due to their length, the spring ribs 31 are placed under a certain tension when the carrier 24 is mounted on the comb shaft. The spring angle β is reduced in the process, so that the carrier 24 cannot be attached to the comb shaft by the spring ribs 31 is pressed upwards or away from a surface of the circular comb shaft. The spring ribs 31 have supports 33 at their ends. The supports 33 shown as examples are shown as convex roundings. Shapes of the supports 33 adapted to a surface of the comb shaft are also conceivable, however.

figure 3 shows a schematic representation of a further embodiment of a carrier 24 according to the invention in cross section. The carrier 24 has a central profile 28 and a granite bearing surface 26 arranged in an arc around a circular comb axis 6 . A support surface 27 arranged concentrically to the clothing support surface 26 is also provided on the central profile 28 . The clothing support surface 26 is supported on the central profile 28 via a first strut 29 and a double second strut 30 . In addition to a first pair of spring ribs 31 , a second pair of spring ribs 32 is arranged between the central profile 28 and the first spring rib 31 . The first spring rib 31 and the second spring rib 32 are each formed at a common connection point 37 on the central profile 28 . The first and the second spring ribs 31 and 32 are each provided with a support 33 at their ends. When the carrier 24 is not installed in a combing device, an enveloping circle 45 inserted into the supports 33 of the spring ribs 31 and 32 has a smaller radius than a radius of the support surface 27 . As a result, the spring ribs 31 and 32 are deformed when the carrier 24 is fastened to a crested shaft, with maximum deformation occurring as a result of the support surface 27 resting on the crested shaft.

figure 4 shows a schematic representation of a combing device according to the invention in a longitudinal section. The combing device comprises a circular comb 7 and a compensating element 25, the circular comb 7 essentially being formed by a carrier 24 and a combing set (not shown) attached thereto. The carrier 24 has a clothing support surface 26 which is connected to a central profile 28 via a strut 30 . The central profile 28 rests with a molded support surface 27 on a comb shaft 8 .

The compensating element 25 is fastened to the circular comb shaft 8 with fastening elements 39 . The carrier 24 and thus the circular comb 7 with the compensating element 25 are braced through the circular comb shaft 8 by means of fastening elements 38 that penetrate through the circular comb shaft 8 . In addition, a bolt 41 is inserted between the circular comb shaft 8 and the central profile 28 of the carrier 24 . The bolt 41 serves to protect the fastenings 38 from the loads caused by acceleration forces 42 (see figure 5 ) largely free. O-rings 43 are attached to the respective ends of the bolt 41 . The O-rings 43 enable the bolts 41 to be accommodated with a precise fit in the bores 44 provided in the central profile 28, while at the same time there is a certain elasticity in the transfer of force and thus a reduction in wear by averting impacts during a load change. At its end facing the circular comb shaft 8 , the bolt 41 has a surface 47 molded onto the surface 40 of the circular comb shaft 8 and an internal thread 46 that is open toward the circular comb shaft 8 . As a result, the bolt 41 can be clamped in a torque-proof manner on the circular comb shaft 8 with a threaded bolt 48 which extends through the compensating element 25 and the circular comb shaft 8 .

The circular comb 7 is shown with a length L along a circular comb axis 6, the length L corresponding to the extension of a combing device that is normally used. As indicated, however, a shortened length M of the carrier 24 is also possible, since a clothing support surface 26 that is continuous over the entire length L is not absolutely necessary. Advantageously, however, the length M of the carrier 24 corresponds to the length L of the circular comb 7, in particular when the carrier 24 is designed as a hollow profile as in FIGS Figures 2 and 3 shown.

figure 5 shows a schematic representation of a combing device according to the invention in a view X after FIG Figure 4 and Figure 6 shows an enlarged view of a detail figure 5 . The illustration shows the carrier 24 mounted on the circular comb shaft 8 and braced with the compensating element 25 via fastening elements 38. The acceleration forces 42 acting on the carrier 24 and the compensating element 25 are also shown. The enlarged representation shows the effect of the spring ribs 31 when the fastening elements 38 are not fully tensioned adjustable gap A between the support surface 27 of the central profile 28 and a surface 40 of the circular comb shaft 8 is shown. The gap A can be increased or decreased by tightening or loosening the fasteners 38 .

figure 7 shows a schematic representation of a second embodiment of a combing device in cross section. In the alternative embodiment of the combing device shown, a supporting body 53 is fastened on the round comb shaft 8 . A compensating element 25 and a carrier 49 are arranged opposite one another on this supporting body 53 and are clamped to one another via fastening elements 59 by the circular comb shaft axis 6 .

The carrier 49 has a central profile 51 and a granite bearing surface 26 . The clothing support surface 26 is adapted to the nature of the combing clothing (not shown) to be fastened thereon. In the present example, the clothing support surface 26 extends over a comb angle α in an arc around a circular comb axis 6. The circular comb axis 6 serves as a reference point for the entire carrier 24 as well as the support body 53. On a side of the central profile 51 opposite the clothing support surface 26 a support surface 50 is formed on the central profile 51 . The support surface 50 is designed concentrically to the clothing support surface 26 with a radius adapted to the support body 53 .

The clothing support surface 26 is supported on the central profile 51 via first struts 54 and a second strut 55 . Two pairs of spring ribs 52 and 57 are provided to support the carrier 49 on the support body 53 . The struts 54 and the spring ribs of the pairs of spring ribs 52 and 57 are each arranged in pairs and symmetrically to the central profile 55 . The first struts 54 each have a section 56 that is common to a spring rib 52 and 57 . The spring ribs 52 and 57 are formed on the central profile 55 at a common termination point 58 via the common section 56 . The spring ribs 52 and 57 have supports 33 at their ends. When the carrier 49 is fastened to the support body 53, the spring ribs 52 and 57 come to rest with their supports 33 on the surface of the support body 53 and are deformed when the fastening elements 59 are tightened.

A maximum deformation of the spring ribs 52 and 57 is limited by the support surface 27 resting on the support body 53 .

The present invention is not limited to the illustrated and described embodiments. Modifications within the scope of the patent claims are just as possible as a combination of the features, even if they are shown and described in different exemplary embodiments.
