Description

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

Such carriers for circular combs are used for combers for combing out a fiber mass (cotton, wool, etc.), it being possible for the fiber mass to be presented in the form of cotton webs wound on sleeves or in the form of individual fiber tapes. The comb play numbers (comb play / minute) have increased significantly in recent years, which also means an increase in productivity.

The round combs used in practice for the combing machine consist of a round comb carrier which is provided with a clamping hub with which it is fixed in a rotationally fixed manner on a driven round comb shaft. A comb segment is fastened on a partial circumference of the circular comb carrier, with which the end of the fiber mass (also called fiber beard), which is presented by a pair of pliers, is combed out. In an alternative embodiment, circular comb carriers are used, which are applied to a supporting body, the supporting body in turn being held on a driven circular comb shaft.

The requirements for such a round comb and thus for the carrier have been increased, for. B. when the circular comb no longer has a continuous speed, but is driven with a discontinuous rotary movement 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, especially 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 was proposed, which improves known solutions and the circular comb has a lower moment of inertia than previously known solutions. It is suggested that the carrier consists of a hollow profile which has an outer arcuate section for receiving the combing set and with an inner section opposite this, with an open in the direction of the shaft, semicircular trough which extends in the longitudinal direction of the hollow profile and over which the carrier supported on a shaft. The mass and thus the moment of inertia of the carrier can thus be kept low.

However, it has been shown that with the in the EP 2 426 239 A1 solution shown, the circular trough with which the hollow profile is supported on the round comb shaft is difficult to edit, so that a perfect support of the hollow profile is guaranteed on the round comb shaft and it does not lead to tension. In addition, it is difficult in this embodiment to vary or adjust the distance between the enveloping circle of the combing set and the circular comb axis. With such an adjustment, the distance between the lower pliers plate of the pliers and the enveloping circle of the combing set of the circular comb can be adjusted in order to ensure optimal combing. Such adjustability through the use of an arcuate spacer is such. B. in the DE 297 20 656 U1 shown and described. However, an exact setting option down to the smallest step sizes is not possible with such an arcuate element. For example, to change the envelope radius of the combing set of the round comb, the one in the DE 297 20 656 U1 shown arc-shaped spacer element is replaced by another, arc-shaped 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. This can cause tension between the carrier and the spacer.

Further discloses the EP 2 789 716 A1 a circular comb with a support, which is provided with an inner portion protruding toward the shaft, which has a recess which is open in the direction of the shaft and extends in the longitudinal direction of the hollow profile and in which a support element is accommodated which, on the one hand, extends over a first Support surface on a base of the recess and on the other hand on a second support surface on the outer circumference of the shaft. Here are between the support element and Interchangeable spacer elements are provided on the base of the depression. This is intended to make it possible, by simply inserting precise spacing elements between the base body and the support element, to precisely set the radius of the enveloping circle of the combing set. However, it is disadvantageous that an adjustment of the distance between the lower pliers plate of the pliers and the enveloping circle of the combing set 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 to readjust the distance in order to be able to replace the spacer elements.

The object of the present invention is therefore to provide a carrier for a circular comb, which enables a continuous adjustment of the distance between the lower pliers plate of the pliers and the enveloping circle of the combing set of the circular comb, it being possible to change the setting without removing the circular comb.

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

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 is proposed, the clothing support surface and the support surface being arranged in a concentric circular shape around a circular comb axis in a cross section 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 for supporting the carrier on a round comb shaft or on a support body, the spring ribs of the first pair of spring ribs each having a support facing the round comb axis at an end facing away from the central profile.

The carrier essentially consists of a central profile, a clothing support surface provided or attached to the central profile and also on the central profile spring ribs attached in pairs. The combing attachment is fastened to the clothing support surface with suitable means, for example with screws, by welding or gluing. Combing sets consisting of individual wire strips applied to the set bearing surface or also combing sets consisting of prefabricated combing elements which are applied to the set supporting surface are used. The clothing contact surface is arranged in the form 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, and this can be integrally 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 designed as ribs with an end directed freely into the space against the circular comb axis, or in the space below the support surface. At the ends of the spring ribs, supports are provided which are brought into contact with a maximum deflection when the support surface is in contact with a surface of a round comb shaft located in the round comb axis or on a surface of a support body held on the round comb shaft. The distance of the respective support from the circular comb axis is thus identical to a radius of the support surface. The spring ribs are deflected accordingly when the carrier is mounted on the round comb shaft through the surface of the round comb shaft. The supports provided on the spring ribs can be provided as actual straight or curved surfaces. Whereby a convex shape of the ends of the spring ribs is to be understood as a support in the sense of the application. In the case of a convex design of the ends of the spring ribs, a line-shaped contact of the spring rib on the surface of the round comb shaft occurs when it contacts the round comb shaft.

In an advantageous embodiment, the clothing support surface is attached to the central profile or 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 selected such that no support body is necessary between the carrier and the round comb shaft and the carrier can be attached directly to the round comb shaft. The number of struts between the clothing support surface and the central profile depends on the size of the segment of the circle 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. With a large circumferential angle of the clothing support surface, this results in a more stable support of the outer areas of the clothing support surface on the round comb shaft. 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 in their course from the central profile to support by at least one kink into a first element section and a second element section, the first element section and the second element section including a spring angle of 50 to 90 degrees. As a result of this design, the spring rib is not deformed as a whole by forces applied to the supporting 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, the entire change in direction always being seen as a spring angle. As an alternative to a kink, the spring ribs can also be curved under a certain radius. Special advantages from this construction of the spring rib result 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 must 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 via two to six struts. If several struts are provided between the clothing support surface and the central profile, this results in a more rigid construction and dimensional stability of the clothing support surface can also be guaranteed with high acceleration forces. An influence on the dimensional stability of the clothing support surface by the deformation of the spring ribs is also excluded.

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

Preferably, the spring ribs each arranged on one side of the central profile have a common connection point on the central profile in a version of the carrier with direct mounting on the round 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 disk with a certain length, the length being visible in the direction of the circular comb axis. The length of the carrier corresponds to only a fraction of the length of the round comb, and several such short carriers are used to fasten the combing set. The use of several carriers for a combing set has the disadvantage that it is expensive to align the carriers in order to achieve a concentric arrangement of the combing set with the round comb shaft. The length of the carrier therefore advantageously corresponds to a length of the round comb. This has additional the advantage that the round comb with the combing set can be preassembled before it is installed in a comber. 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 enables the struts as well as the spring ribs to have a longitudinal extension corresponding to the length of the round comb, as a result of which greater spring forces can be absorbed by the spring ribs. The support 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 interrupted alternately and, for example, can be formed over 50 percent of the length of the circular comb. However, the support surface as well as the supports of the spring ribs and the clothing support surface are particularly preferably formed over the entire length of the carrier.

The supports of the spring ribs are advantageously arranged concentrically to the support surface, 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 round comb shaft or the support body and the support is pressed away from the round comb shaft or the support body under the bending force of the spring ribs. In order to achieve such a tension, it would also be conceivable to appropriately shape the surface of the round comb shaft or of 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 counterweight is proposed, the circular comb having a carrier with a clothing contact surface. The carrier and the counterweight are mutually arranged on a round comb shaft and clamped together with fastening elements by the round comb 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, each consisting of a spring rib on both sides of the support surface, the spring ribs each having a support on an end facing away from the central profile to support the carrier. The design of the supports can be adapted to the surface of the round comb shaft. Basically is however, a support does not mean a surface in the sense of a plane, but rather a defined shape 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 round comb shaft over the length of the spring rib. The support of the support ribs on the round comb shaft enables stable support of the support even with a narrow support surface on the central profile.

In an alternative embodiment, a combing device with a circular comb and a counterweight is proposed, the circular comb having a carrier with a clothing contact surface and a support body. The support body and the counterweight are mutually arranged on a round comb shaft and clamped together with fastening elements by the round comb shaft. 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, which have a support body in their design, can be retrofitted with an advantageous support as described above without having to replace the existing combination of support body and compensating element.

When the support surface is in contact with a surface of the round comb shaft or a surface of the support body, the spring ribs with their supports are advantageously brought into contact with a maximum tension on the surface of the round comb shaft or the surface of the support body. When the carrier is fastened to the round comb shaft or the support body, the support surface of the carrier serves as a stop, whereby the approach of the carrier to the round comb shaft or the support body is stopped when this stop is reached. A further deformation of the spring ribs is therefore no longer possible when the stop is reached and because of the Touching the supports and the surface prevents the spring ribs from being overstretched. Also, the attachment of the carrier corresponds to a setting of the maximum distance between the lower pliers plate and the enveloping circle of the comb set located on the carrier when the support surface is in contact with the circular comb shaft. If the fastening is now loosened by unscrewing the fastening screws, the support and thus the round comb are lifted off the round comb shaft or the support body by the spring ribs and a gap is formed between the support surface and the surface of the round comb shaft or the support body. At the same time, the distance between the lower pliers plate and the enveloping circle of the combing set is reduced. However, the spring ribs continue to ensure stable attachment of the carrier and thus of the circular comb to the circular comb shaft or the support body.

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

It is also advantageous if the counterweight is held in a rotationally fixed manner on the round comb shaft with fastening elements, regardless of the carrier. This makes it possible to replace the carrier without having to remove the counterweight from the round comb shaft.

It is also advantageous if, independently of the fastening elements for bracing the carrier with the counterweight, a force transmission element is provided between the carrier and the round comb shaft for transmitting the acceleration forces from the round comb shaft to the carrier. In order to avoid a high load on the fastening elements or the spring ribs due to the acceleration forces occurring, an additional force transmission element is provided. The acceleration forces arise from a superposition of a basic speed with a sinusoidally increasing and decreasing speed. This type of movement is necessary to optimize the entire combing process. The forces which occur due to the acceleration of the rotational speed of the round comb shaft with each revolution are transmitted from the round comb shaft to the carrier by the force transmission element, as a result of which the spring ribs are relieved accordingly.

Advantageously, the force transmission element is designed as a bolt which has an internal thread and in one end area has a surface molded onto the round comb shaft. The bolt is braced against the circular comb shaft with a threaded bolt which extends through the round 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 does not contribute to the bracing of the carrier on the round 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 as well as the fastening elements of the carrier are largely relieved of transverse forces. This relief enables a reduction in the number of fastening elements provided today. For bracing a round comb, only two fastening screws can be used instead of four fastening screws. This leads to an easier assembly and for a user-friendly setting of the round comb. The use of O-rings enables the bolts to be used without play, which counteracts wear of the spring ribs when the acceleration forces occur due to a reversal of direction of the forces occurring. The bolts also do not fall out of the holes when the round comb is removed by using O-rings. Another positive aspect is that when the carrier is disassembled, the bolts can remain on the round comb shaft, which means that the carrier is positioned correctly when the carrier 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 combing machines, for. 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 pliers unit, which is pivotally mounted on the swivel arms 3 and 4 around the pliers shaft 5 and the circular comb axis 6 back and forth in the comber. The pliers shaft 5 is driven by a drive (not shown in more detail) in order to give the pliers unit a back and forth movement. In the round comb axis 6, the round comb shaft 8 is arranged on which a round comb 7 is fastened in a rotationally fixed manner. The round comb shaft 8 with its round comb axis 6 is also driven continuously or discontinuously by a drive, not shown, in the direction of rotation 23. The circular comb 7 fastened below the pliers unit on the round comb shaft 8 in the known solution shown consists of two hubs 9 fixedly spaced apart from one another on the round comb shaft 6, on the outer circumference of which on the one hand a base body 10 and on the other hand a counterweight 11 are fastened. The counterweight 11 is attached, as shown schematically, 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 schematically illustrated screws. A combing attachment 13 is fastened above the base body 10, which, like the counterweight 11, extends over the entire length L (see FIG. 4) of the circular comb 7. The circumferential angle of the combing set 13 is approximately 90 degrees in known combing machines and is also referred to as the "combing angle".

The pliers assembly is formed from a pliers frame 14 to which a lower pliers plate 15 and an upper pliers plate 16 are attached. In the embodiment shown, the pliers unit is closed, the fiber beard 17 protruding from the clamping point of the pliers unit being gripped and combed out by the combing set 13. The combing is essentially determined by the distance C between the lower pliers plate 15 and an enveloping circle 2 of the combing set 13. Also in the tong frame 14, a feed roller 18 is rotatably mounted above the lower tong plate 15, which, for. B. is gradually driven by a ratchet drive, not shown. Via this feed roller 18, a cotton wool 19 (or individual slivers) fed to the combing device 1 is fed to the clamping point of the pliers unit. After the combing process of the fiber beard 17, the pliers unit is pivoted in the direction of a subsequent tear-off roller pair 20. During this swiveling process, the pliers unit opens and the combed end of the batting 19 or the fiber beard 17 is placed on the end of a previously formed nonwoven fabric 21 and soldered to it under the action of the clamping point of the tear-off 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 support 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. 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 round 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 for supporting the carrier 24 on a round comb shaft. The struts 29 and 30 and the spring ribs of the spring rib pair 31 are each arranged in pairs and symmetrically to the central profile 28. The first struts 29 each have a section 34 common to a spring rib 31. The spring ribs 31 are formed on the central section 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, the first element section 35 and the second element section 36 enclosing a spring angle β. The configuration of the spring ribs 31 in the 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. The spring ribs 31 are placed under a certain tension due to their length when mounting the carrier 24 on the round comb shaft. The spring angle β is reduced in this case, so that the carrier 24 is secured by the spring ribs 31 without being fastened to the round comb shaft is pushed upwards or away from a surface of the round comb shaft. The spring ribs 31 have supports 33 at their ends. The supports 33 shown as examples are shown as convex fillets. However, shapes of the supports 33 which are adapted to a surface of the round comb shaft are also conceivable.

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 support surface 26 arranged in an arc around a circular comb axis 6. Also provided on the central profile 28 is a support surface 27 arranged concentrically with the clothing support surface 26. The clothing support surface 26 is supported on the central profile 28 via a first strut 29 and a double strut 30. Next 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 on 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 round comb shaft, with a maximum deformation being provided by the support surface 27 abutting the round comb shaft.

Figure 4 shows a schematic representation of a combing device according to the invention in a longitudinal section. The combing device comprises a round comb 7 and a compensating element 25, wherein the round comb 7 is essentially formed by a carrier 24 and a combing set (not shown) attached to it. 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 lies with a molded support surface 27 on a round comb shaft 8.

The compensating element 25 is fastened to the round comb shaft 8 with fastening elements 39. Through the round comb shaft 8, the carrier 24 and thus the round comb 7 with the compensating element 25 are clamped on the round comb shaft 8 via penetrating fastening element 38. In addition, a pin 41 is inserted between the round comb shaft 8 and the central profile 28 of the carrier 24. The bolt 41 serves 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 allow the bolts 41 to be accommodated in the provided bores 44 in the central profile 28 with a precise fit, at the same time there is a certain elasticity in the force transmission and thereby a reduction in wear and tear due to the deflection of blows during a load change. At its end facing the round comb shaft 8, the bolt 41 has a surface 47 formed on the surface 40 of the round comb shaft 8 and an internal thread 46 open to the round comb shaft 8. As a result, the bolt 41 can be clamped in a rotationally fixed manner on the round comb shaft 8 with a threaded bolt 48 which passes through the compensating element 25 and the round 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 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 according to the Figure 4 and Figure 6 shows an enlarged view of a detail according to Figure 5 . The illustration shows the carrier 24 mounted on the round 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. In the enlarged representation, the fastening elements 38 that are not fully tensioned due to the action of the spring ribs 31 adjustable gap A between the support surface 27 of the central profile 28 and a surface 40 of the round comb shaft 8 is shown. The gap A can be enlarged or reduced by tightening or loosening the fastening elements 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 support 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 support body 53, which are clamped together by fastening elements 59 through the round comb shaft axis 6.

The carrier 49 has a central profile 51 and a granite support 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 and also the support body 53. On one 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 for supporting the carrier 49 on the support body 53. The struts 54 and the spring ribs of the spring rib pairs 52 and 57 are each arranged in pairs and symmetrically to the central profile 55. The first struts 54 each have a section 56 common to a spring rib 52 and 57. The spring ribs 52 and 57 are formed on the common section 56 in a common end point 58 on the central profile 55. The spring ribs 52 and 57 have supports 33 at their ends. When the carrier 49 is fastened on 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 bearing against the support body 53.

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