Abstract
Description
Technical Field
[0001] This invention relates to a top comb retainer for securing a top comb carrier in a combing machine, and a top comb carrier. The top comb retainer has: a guide portion having a guide groove for receiving the top comb carrier; a fastening portion for securing the top comb retainer to the combing machine; a retaining portion; and a clamping lever connected to the fastening portion via a rotating shaft and connected to the retaining portion via a locking coupling. Background Technology
[0002] The top comb carrier, inserted into the top comb holder, performs an approximately elliptical motion within the combing machine, and is thus subjected to a constantly varying acceleration force due to its engagement with the sliver to be combed. Overall, this results in high mechanical loads on the connection and mounting surfaces of the top comb carrier in the receiving section of the top comb holder due to the weight of the top comb itself. These connections are designed such that the top comb holder has a receiving section into which the top comb is inserted and secured in place by means of fastening devices. The fastening devices are movably fitted onto the holder, which takes the form of a spring-shaped retaining clamp made of sheet metal. In the closed state, the retaining clamp, made of sheet metal, engages around the top comb and holds it in its position relative to the top comb holder.
[0003] In conventional designs, the top comb carrier is typically made of aluminum, thus possessing a precisely dimensional fastening area. In contrast, retaining clamps made of sheet metal or steel become less precise in size due to the hardening process. This results in linear loads between the fastening area of the top comb carrier and the retaining clamps, causing mechanical wear in the fastening area. This mechanical wear due to linear loads on the surface of the fastening area of the top comb carrier has the disadvantage that retaining clamps made of sheet metal no longer optimally engage around the fastening area altered by mechanical wear, causing the top comb carrier to move with clearance in the receiving portion of the top comb retainer due to elliptical motion. Consequently, the top comb no longer produces the desired combing performance, and combing quality deteriorates uncontrollably. Furthermore, the elliptical movement of the top comb carrier in the receiving section of the top comb holder causes the connection of the retaining clamp to the top comb holder to loosen during the operation of the combing machine, and thus the retaining clamp is only loosely fastened to the top comb holder, thereby greatly weakening the desired spring-like clamping force of the retaining clamp, which is used to fix the top comb carrier in the receiving section of the top comb holder.
[0004] Another drawback of known designs with retaining clamps is that the retaining clamps cannot close without being inserted into the top comb carrier, because they can only close when engaged with the fastening area on the top comb carrier. However, in many cases, the comber is equipped with a separate top comb carrier. If the clamp is now open, the back-and-forth movement of the jaws causes the clamp to move loosely with the comber during assembly. The retaining clamp will loosen when it is fastened to the top comb retainer, such that when the retaining clamp is later closed over the fastening area of the top comb carrier, the top comb carrier is held with clearance in the receiving portion of the top comb retainer.
[0005] DE 102 52 098 A1 attempts to remedy this situation and discloses a top comb retainer comprising a top comb carrier, wherein a wear protector (particularly a plastic material with good settling ability and good surface sliding properties) is disposed in the contact area between the fastening area of the top comb carrier and the retaining clamp of the top comb retainer. Furthermore, CH 707012 A2 discloses a top comb carrier comprising a fastening area around which the retaining clamp engages, the fastening area being made of a material with a hardness greater than or equal to that of the top comb carrier itself. The disadvantage of these developments is the use of complex manufacturing processes with specific material pairings, where the retaining clamp is used to maintain the fastening structure of the top comb carrier. Summary of the Invention
[0006] The problem solved by this invention is to allow the top comb retainer and top comb carrier to eliminate the disadvantages of the prior art and to allow the top comb retainer to be locked independently of the insertion of the top comb carrier.
[0007] This problem is solved by the features of the independent claims.
[0008] To address this problem, a top comb retainer for securing a top comb carrier in a combing machine is proposed. The top comb retainer includes: a fastening portion for securely attaching the top comb retainer to the combing machine; a guide portion having a guide groove for receiving the top comb carrier, the guide portion being connected to the fastening portion and the guide groove having a longitudinal axis; a retaining portion arranged on the fastening portion to point away from the fastening portion in the same direction as the longitudinal axis of the guide groove; and a clamping lever connected to the fastening portion via a rotating shaft and connected to the retaining portion via the guide portion in a gripping manner. The connection between the clamping lever and the retaining portion is designed as a locking connection, and the clamping lever has at least two pressure elements for securing the top comb carrier in place.
[0009] The proposed top comb retainer consists of three rigidly interconnected parts: a fastening part, a retaining part, and a guiding part. The fastening part is used to securely connect the top comb retainer to the combing machine. For this purpose, the fastening part has a slotted through-hole, for example, for screws. The top comb retainer is secured to a part of the combing machine by means of screws passing through the through-hole. The advantage of the slotted through-hole is that the position of the top comb retainer in the combing machine can be set according to the size of the slot.
[0010] The guide portion has a guide groove and is disposed adjacent to the fastening portion and / or the retaining portion. The guide groove is designed to open away from the fastening portion and close towards the fastening portion. The correspondingly shaped top comb carrier can be introduced into the guide groove towards the fastening portion along the longitudinal axis of the guide groove. The dimensions of the guide groove and the top comb carrier are matched to each other, such that the top comb carrier slides into the guide groove with a small amount of play. The guide groove, which is closed at the bottom, automatically causes the carrier to be correctly positioned after the top comb carrier has been introduced into the guide groove. Only after the clamping lever has been closed can the top comb carrier be installed in the guide groove without play and thus in the top comb retainer.
[0011] The retaining portion is disposed adjacent to the fastening portion, and the end of the retaining portion away from the fastening portion is used to form part of a locking coupling for clamping the lever. The locking coupling will be understood as a system consisting of two parts that are at least partially interlocked. The first part engages in another second part, which is adapted to the shape of the first part. The interlocking causes locking, as the interlocking is achieved through slight deformation during the locking process in which one part participates in the locking coupling. Due to the fact that the retaining portion is arranged on the fastening portion to point away from the fastening portion in the same direction as the longitudinal axis of the guide groove, the locking coupling is located above the open configuration of the guide groove, and the top comb carrier is introduced into the guide groove over the locking coupling.
[0012] A clamping lever is provided as another component of the top comb retainer. The clamping lever is connected to the retaining or fastening portion via a rotating shaft. The rotating shaft is held in the retaining portion, and the clamping lever is held on the rotating shaft so as to be pivotable about said shaft. For example, a steel pin on which the clamping lever is held can be provided as the rotating shaft. However, other types of rotating shafts are also conceivable, such as knobs provided in the retaining portion, which engage in corresponding recesses in the clamping lever and similarly allow the clamping lever to pivot about the rotating shaft. At the end of the clamping lever remote from the rotating shaft, the clamping lever is shaped such that it locks around a portion of the retaining portion designed as a locking coupling. To lock the clamping lever onto the retaining portion, the clamping lever is pivoted about the rotating shaft toward the retaining portion until it strikes the retaining portion. By applying force in the pivoting direction, the clamping lever is lifted over the portion of the retaining portion provided for the locking coupling. As a result, the end of the clamping lever is held in a closed position by extending over the retaining portion. With the aid of locking, the clamping lever is subjected to tension between the rotating shaft and the locking coupling, and can only be released from the closed position by releasing the engagement above the retaining portion. Due to the arrangement of the locking coupling, the clamping lever is also engaged around the top comb carrier located in the guide slot.
[0013] One advantage of this design is that the top comb retainer can close even without the top comb carrier inserted into the guide slot. This allows for trial runs of the combing machine for inspection and adjustment purposes without having to closely monitor the components that move freely and in an uncontrolled manner.
[0014] At least two pressure elements are also disposed within the clamping lever. When the clamping lever is closed, these pressure elements hold the top comb carrier in the guide slot with zero play. These pressure elements may be integrally molded onto the clamping lever or at least held within the clamping lever. In particular, resilient plastic elements are suitable as pressure elements, and other designs of pressure elements, such as spring steel sheet, may also be used. When the clamping lever is closed, the pressure elements press against the surface of the top comb carrier and are slightly compressed. However, as an alternative, the pressure elements may also be designed as springs, which similarly apply a holding force to the top comb carrier when the clamping lever is closed. The pressure elements are fastened to the clamping lever such that they move with the clamping lever as the clamping lever pivots. For example, the pressure elements may be fixed to the clamping lever with screws or bonded to the clamping lever with adhesive. The pressure elements are advantageously held within the clamping lever so that they can be replaced if their flexibility becomes fatigued over time and the resulting clamping force is reduced.
[0015] The pressure element is advantageously arranged in the clamping lever such that the resulting component force is directed toward the guide slot from different directions, each of which is perpendicular to the axis of rotation. When the top comb carrier is inserted into the guide slot and the clamping lever is closed, the pressure element presses against the surface of the top comb carrier opposite to the pressure element, thereby generating a component force. Under applied force, the clamping lever presses against the retaining portion and locks into the locking coupling. Even under tension, the locking coupling holds the clamping lever in its closed position. The locking coupling can only be released and the clamping lever can only be pivoted by applying a force against the locking coupling. In order to hold the top comb carrier in the guide slot in a backlash-free manner, the component force generated by the pressure element is directed toward the top comb carrier from different directions. By orienting the component force perpendicular to the axis of rotation, it is prevented that the pressure element transfers force to the clamping lever, which could cause the clamping lever to shift on the axis of rotation and thus become unusable for holding the top comb carrier.
[0016] The first component force is preferably arranged along the longitudinal axis of the guide groove, and the second component force is arranged transversely to both the longitudinal axis of the guide groove and the axis of rotation. Therefore, the first component force ensures that the inserted top comb carrier slides completely into the guide groove and abuts the closed end of the guide groove. When the clamping lever closes, the first component force then presses the top comb carrier into the guide groove via the pressure element along the longitudinal axis of the guide groove. The second component force acts such that the top comb carrier presses against the side of the guide groove opposite to the pressure element. As a result, the play required to introduce the top comb carrier into the guide groove is eliminated, and the top comb carrier is fixed in place in the predefined position by the guide groove adjacent to the top comb retainer.
[0017] At least one of the pressure elements is advantageously made of a conductive plastic material. The conductive pressure element makes it possible to monitor the presence of the top comb carrier in the top comb holder. Since the top comb holder can also close without the inserted top comb carrier, it is possible to operate the comber without the top comb. To avoid this or to supplement operator visual inspection, when the top comb carrier is inserted, electrical contact is established via the pressure element through the closing clamping lever. The comber controller can easily monitor the electrical contact. The pressure element that generates the second component force is particularly preferably made of a conductive plastic material. The fact that the second pressure element presses the top comb carrier against the rear wall of the guide groove ensures greater reliability in establishing contact.
[0018] In an alternative embodiment of the conductive pressure element, a sheet metal element for conducting the measurement current is disposed on a clamping lever. The sheet metal element can, for example, consist of a spring steel sheet screwed to the clamping lever. Slight deformation of the spring steel sheet in the closed state of the top comb retainer establishes reliable contact between the sheet metal element and the top comb carrier. This separates the monitoring function from the fastening function. This means a wider range of material choices are available for the pressure element.
[0019] Another advantage is that the pressure elements are cylindrical, and each is held in a recess within the clamping lever, these pressure elements being enclosed by the associated recess for more than 180 degrees. The cylindrical pressure elements are arranged such that their cylindrical axis is parallel to the axis of rotation of the clamping lever. The pressure elements can be easily installed by pressing them into the recesses provided for them in the clamping lever. By enclosing them for more than 180 degrees, the pressure elements are captured in the recesses and will not fall out. Nevertheless, the pressure elements can be easily replaced in the event of signs of fatigue or aging. Due to the parallel arrangement of the cylindrical pressure elements relative to the axis of rotation, when the clamping lever is closed, the pressure elements initially act on the fixed carrier along the contact line. By means of the deformation of the elastic pressure elements when the clamping lever is locked into the retaining portion, surface contact is established between the top comb carrier and the associated pressure element, thereby allowing the component force acting in each case to act optimally against the surface of the top comb carrier.
[0020] The rotating shaft is preferably releasably held in the top comb retainer on the side of the guide groove opposite to the retaining portion. The rotating shaft is advantageously designed as a pin fixed in place within the clamping lever. As a result of the fact that the rotating shaft, or the clamping lever, is held together with the rotating shaft on the side of the guide groove opposite to the retaining portion, targeted force application of the pressure element in the guide groove region can be achieved. The releasable fastening of the rotating shaft allows for replacement of the clamping lever without having to remove the top comb retainer from its set position in the combing machine.
[0021] The guiding, fastening, and retaining portions are advantageously positioned as a single piece. The advantage of this one-piece design is the absence of connection points subject to tolerances. In this embodiment, for example, the part can be manufactured as an injection-molded part. Because connection points are unnecessary, a wider range of materials are available. For example, the part can be made of plastic or metal.
[0022] In a preferred embodiment, the locking coupling has a locking element that engages with and protrudes from a retaining portion, and a shaped portion that engages with a clamping lever, the shaped portion at least partially corresponding in shape to the locking element. During closure of the locking coupling, the locking element is received in the shaped portion. For example, the design of the shaped portion (which has the effect that the locking element must overcome resistance upon impact with the shaped portion in order to be received in the shaped portion) causes the locking element to be effectively locked into the shaped portion. This can be achieved by creating a narrow point on the shaped portion or a flange on the locking element. A characteristic feature of all forms and designs of locking couplings is that they can only be disengaged from the locked position by applying force.
[0023] The locking element is particularly preferably a bolt, and the forming portion surrounds the bolt by more than 180 degrees. In this embodiment, the forming portion in the clamping lever is a circular opening that matches the bolt and has a fan-shaped opening of less than 180 degrees when guided toward the bolt. As the clamping lever moves against the bolt, the opening expands with the corresponding force applied by the bolt upon impact with the forming portion, allowing the bolt to slide into the circular portion of the forming portion. Once the maximum diameter of the bolt has passed through the opening, the expansion is reversed by the elasticity of the material, and the bolt is retained in the forming portion. The distance between the axis of rotation and the center of the bolt is preferably less than the distance between the axis of rotation and the center of the forming portion in the clamping lever. This allows for the bolt to be mounted in the forming portion without play and, therefore, the clamping lever to be mounted in the retaining portion without play. The force required to release the locking coupling by pivoting the clamping lever outward is greater than the component force acting on the pressure element and therefore on the clamping lever.
[0024] A top comb carrier for fastening in a top comb retainer as described above is also proposed. The top comb carrier has a retainer plate and a reinforcing element mating on the retainer plate, the retainer plate having a longitudinal extension and a top comb fastening surface. At least at both ends of the longitudinal extension, the retainer plate has T-shaped or L-shaped areas. The reinforcing element mating on the retainer plate is used to make the retainer plate more torsional and flexurally rigid. The top comb fastening surface provided on the retainer plate is used to attach the top comb. In present designs, fastening holes for securing the top comb needle cloth with screws are provided in the top comb fastening surface. The longitudinal extension of the retainer plate corresponds to the width of a conventional combing point in a combing machine. The T-shaped or L-shaped areas at the respective ends of the top comb carrier are designed such that there is a long leg and at least one short leg projecting at a right angle from the longer leg. In the case of a preferred T-shaped design at the ends of the top comb carrier, the short leg is arranged such that it points away from the long leg at a right angle on both sides of the long leg. The dimensions of the T-shaped or L-shaped end of the top comb carrier match the dimensions of the guide groove of the top comb retainer. Therefore, the top comb carrier can be inserted into the guide groove of the top comb retainer.
[0025] In the installed state, two component forces caused by the pressure element in the clamping lever act on the two legs at the T-shaped or L-shaped ends of the retainer plate. The pressure element arranged in the clamping lever presses the top comb carrier into a defined position in the guide groove of the top comb retainer. The component forces acting on the top comb retainer do not simultaneously fix the retainer, as is the case in the original design with retaining clamps. The retainer is secured by a locking coupling between the clamping lever and the retaining portion and is not integrated into the actual fastening of the top comb carrier.
[0026] The top comb fastening surface is preferably inclined at 5 to 20 degrees relative to the retainer plate. In the installed state, the orientation of the retainer plate corresponds to the arrangement of the long legs at the end of the top comb carrier, and thus, the orientation of the retainer plate corresponds to the longitudinal axis of the guide groove of the top comb retainer. When the top comb carrier is installed in the top comb retainer or removed from the top comb retainer, the top comb carrier moves in the direction of the longitudinal axis of the guide groove of the top comb retainer. Due to the inclination of the top comb fastening surface, the top comb carrier does not move along the orientation of the top comb card cloth, but moves in a different manner. As a result, the top comb carrier can be introduced or extended into the top comb retainer in a plane inclined relative to the top comb fastening surface. The limited space available in the top comb card cloth area of the combing machine can be better utilized. With the corresponding inclination, the top comb carrier can also be separated from the top comb retainer, regardless of the position of the combing unit.
[0027] The top comb carrier is advantageously at least partially covered with a conductive coating, preferably a chemically plated nickel coating. This coating makes it easier to maintain contact between the conductive pressure element and the surface of the retainer plate. This can be electrically determined as soon as the top comb carrier is inserted into the top comb retainer and the clamping lever of the top comb retainer is closed. This prevents the combing unit from being put into operation without the top comb carrier being inserted.
[0028] A method for securing and monitoring a top comb carrier in a combing machine is also proposed. The combing machine includes a top comb retainer and a top comb carrier. The top comb retainer has: a guide portion having a guide groove for receiving the top comb; a fastening portion for securely attaching the top comb retainer to the combing machine; and a retaining portion and a clamping lever connected to the retaining portion via the guide portion in a gripping manner by means of a locking coupling. The combing machine includes a top comb carrier having a longitudinal extension, at each of its two ends as viewed in the longitudinal extension, the top comb carrier having a T-shaped or L-shaped region. At least two pressure elements are disposed in the clamping lever. The top comb carrier is introduced into the guide groove of the guide portion, and the clamping lever is locked to the retaining portion via the locking coupling, the pressure elements pressing against the T-shaped or L-shaped region of the top comb carrier by a locking movement.
[0029] Advantageously, when the clamping lever is locked, a conductive connection is established between the top comb carrier and the top comb retainer. The presence of the top comb carrier in the top comb retainer can be monitored via this closed electrical connection. By means of monitoring, it is possible to prevent the combing operation from starting without inserting the top comb carrier and therefore without inserting the top comb card cloth. Operation is also impossible in the event of incorrect closure of the clamping lever. Attached Figure Description

[0037] Figure 1 This is a schematic diagram of a top comb fastener according to the prior art, wherein a top comb retainer 1 is fastened in a combing machine. The top comb retainer 1 has a fastening portion 4, a guide portion 5, and a retaining portion 6. In the guide portion 5, a guide groove 7 is provided, which has a longitudinal axis 8 and is intended for receiving the top comb carrier 2. In the retaining portion 6, a shaft 9 is provided, on which a retaining clamp 3 is rotatably mounted. The retaining clamp 3 is shown in its closed position and is indicated by a dashed line to be in its open position. The top comb carrier 2 has a fastening area 10, a retainer plate 27, and a top comb fastening surface 30. On the top comb fastening surface 30, the top comb card cloth 11 is held on the top comb carrier 2 by means of fasteners 12 (e.g., screws). The top comb carrier 2 is inserted into the guide groove 7 along the longitudinal axis 8 and is fixed in place in the guide groove 7 and thus in the top comb retainer 1 via the fastening area 10 and the retaining clamp 3. The retainer 3 moves above the fastening area 10 and bends slightly in the process. Due to this tension in the retainer 3, the top comb carrier 2 is secured in place in the top comb holder 1.
[0038] Figure 2 and 3 The top comb retainer 1 according to the invention is now shown in the closed position. Figure 2 ) and in the open position ( Figure 3 A schematic diagram of the top comb retainer 1 is shown. The top comb retainer 1 has a fastening portion 4, a guide portion 5, and a retaining portion 6. In the view shown, the fastening portion 4, the retaining portion 6, and the guide portion 5 are shown as single parts. However, it is also conceivable to design these three parts as separate elements and connect them together to form the top comb retainer 1, for example, by fixing with screws or bonding with adhesive. In the fastening portion 4 of the top comb retainer 1, a through opening in the form of a fastening hole 18 is provided, through which the top comb retainer 1 can be fastened to the combing machine, for example, by means of a screw (not shown). The fastening hole 18 is designed as an elongated hole to have a certain amount of play that can be adjusted during fastening. A guide groove 7 having a longitudinal axis 8 is provided in the guide portion 5. The guide groove 7 closes towards the bottom of the fastening portion 4 and is designed to open in the other direction (at the top).
[0039] A rotating shaft 14 is also disposed in the guide portion 5. A clamping lever 13 is held at or on the rotating shaft 14. In the illustrated embodiment, the rotating shaft 14 is held in the clamping lever 13 and clamped into a corresponding groove in the guide portion 5. This allows the clamping lever 13, together with the rotating shaft, to be removed from the guide portion 5 and thus from the top comb holder 1 if replacement is necessary due to signs of wear or material fatigue.
[0040] In the closed position ( Figure 2 In the top comb retainer 1, the clamping lever 13 is connected to the guide portion 5 via a rotating shaft 14 and to the retaining portion 6 via a locking coupling 15. Figure 2 The closed position shown and Figure 3 The difference between the open positions shown is the position of the clamping lever 13. The clamping lever 13 can be opened or closed with movement 23. When the clamping lever 13 is closed, the locking coupling 15 is locked. The locking coupling 15 consists of a locking element 16 (e.g., a bolt) mating on the retaining portion and a corresponding formed portion 17 in the clamping lever 13. The formed portion 17 thus adapts to the locking element such that in the locked (closed) state, the locking element 16 is surrounded by the formed portion 17, resulting in locking. The lever 19 is integrally formed on the end of the clamping lever away from the axis of rotation 14. This lever 19 makes it easier to manually move the clamping lever into or out of the locked position.
[0041] Pressure elements 20, 21, and 22 are disposed in the clamping lever 13. In the illustrated embodiment, pressure elements 20, 21, and 22 are shown as cylindrical elements made of a resilient plastic material. Each pressure element 20, 21, and 22 is held in a corresponding recess 26 within the clamping lever 13. The recess 26 is adapted to the geometry of the pressure elements 20, 21, and 22 such that the pressure elements 20, 21, and 22 are surrounded by the clamping lever 13 by more than 180 degrees. Therefore, it is impossible for pressure elements 20, 21, and 22 to fall out of their corresponding recesses 26. The first pressure element 20 is positioned on the clamping lever 13 such that, in the closed position of the clamping lever 13, the element is guided toward the open side of the guide groove 7. The second pressure element 21 and the third pressure element 22 are positioned on the clamping lever 13 such that, in the closed position of the clamping lever 13, the element is guided toward one long side of the guide groove 7. When the clamping lever 13 closes and is inserted into the top comb carrier 2, pressure elements 20, 21, and 23 generate component forces 24 and 25, which therefore act on the top comb carrier 2 (see...). Figure 6 However, with the help of the locking connector 15, the clamping lever 13 can also be held in a fixed closed position without inserting the top comb carrier 2.
[0042] Figure 4 A schematic diagram of a top comb carrier 2 according to the invention is shown, the carrier having a longitudinal extension 29. The top comb carrier 2 has a retainer plate 27 and a reinforcing element 28 extending throughout the longitudinal extension 29. A top comb fastening surface 30 is integrally molded onto the retainer plate 27. In the view shown, the top comb fastening surface 30 is located on the rear side of the retainer plate 27. The top comb fastening surface 30 is arranged at an angle β relative to the retainer plate 27. In the retainer plate 27, in the region of the top comb fastening surface 30, fastening holes 31 for fastening top comb needle cloth (not shown) are provided. As seen in the longitudinal extension 29, T-shaped regions 32 are provided at corresponding ends of the retainer plate 27. The T-shaped regions 32 are integrally molded onto the retainer plate 27. Throughout the longitudinal extension 29, one leg of the T-shape transitions into the reinforcing element 28, and two other legs extend throughout the longitudinal extension 29. The T-shaped or L-shaped area 32 at the location of the top comb holder is necessary for securing the top comb carrier 2; however, the shaped portion of the holder plate 27 between areas 32 is not important for securing the top comb carrier in the top comb holder.
[0043] Figure 5 This is a schematic diagram of the top comb carrier 2 according to the present invention, in which the top comb needle cloth 11 is inserted. (And...) Figure 4Compared to the view shown in the diagram, the top comb carrier 27 is shown from the opposite side. The top comb needle cloth 11 is held on the retainer plate 27 by means of fasteners 12 on the top comb fastening surface 30, which is inclined relative to the retainer plate 27. The top comb needle cloth 11 fits below the reinforcing element 28. T-shaped regions 32 are provided at the corresponding ends of the retainer plate 27.
[0044] Figure 6 This is a schematic diagram of a top comb retainer 1 according to the present invention, wherein a top comb carrier 2 is inserted, and a top comb needle cloth 11 is fastened to the top comb carrier 2 on a top comb fastening surface 30 that fits onto a retainer plate 27. The top comb retainer 1 has a fastening portion 4, a guide portion 5, and a retaining portion 6, as well as a clamping lever 13. A fastening hole 18 is provided in the fastening portion 4. The guide portion 5 has a guide groove 7 having a longitudinal axis 8. The top comb fastening surface 30 is arranged at an angle β relative to the longitudinal axis 8 of the guide groove 7. The top comb carrier 2 is introduced into the guide groove 7 by means of a T-shaped region 32, which fits onto the end of the retainer plate 27 in the longitudinal extension 29 of the carrier. The clamping lever 13 enters a closed position about an axis 14 and locks into a locking coupling 15. Due to the first pressure element 20 located in the clamping lever 13, pressure is applied to the top comb carrier 2 and has a component force 24 in the direction of the longitudinal axis 8 of the guide groove 7, and the top comb carrier 2 is pressed into the guide groove 7. By means of additional second pressure elements 21 and third pressure elements 22 arranged in the clamping lever 13 (see... Figure 3 The clamping lever 13 closes, creating a component force 25 that, transverse to the longitudinal axis 8, pushes the top comb carrier 2 into a defined position within the guide groove 7. After the clamping lever 13 is opened, the top comb carrier 2 can move out of the guide groove 7 along the longitudinal axis 8 and separate from the top comb holder 1.
[0045] This invention is not limited to the embodiments shown and described. Within the scope of the claims, modifications and combinations of features may be made, even if the features are shown and described in different embodiments.
