Description

Technical Field

[0001] This utility model relates to a cutting device for cutting strip-shaped materials, particularly an adhesive rope, comprising a lower strip-shaped blade and an upper strip-shaped blade, wherein the upper blade moves vertically relative to the fixed lower blade for cutting. The lower blade is mounted on a blade holder, which is linearly and horizontally movable on a device frame and can be linearly moved by an adjustment device to change the position of the lower blade relative to the upper blade and to adjust a given cutting gap between them. The device also includes a means for detecting the horizontal movement of the lower blade relative to the upper blade. Background Technology

[0002] Cutting equipment of this type is used, for example, in tire production. They are used to cut strip materials, especially adhesive cords, whether steel wire rope or textile cord. The term "cutting equipment" refers to different types of machines. These are broadly categorized as shears and slitting machines. The shears used here are, for example, gilotis shears, i.e., impact shears with a strip-shaped, vertically movable upper blade and a strip-shaped, fixed lower blade; circular or roller shears with rotatable, horizontally movable circular blades and positioning blade shanks, as considered in this example; or shears with a rapidly rotating saw blade. These shears are used to cut individual strips from an annular conveyor belt. Various types of such shears are described, for example, in DE 20 2013 103 082 U. Slitting machines are used to longitudinally divide an annular belt into two or more partial belts. In most cases, two circular blades are used to separate the material and interact with each other.

[0003] Regardless of the type of cutting equipment, the corresponding tooling system will experience a certain amount of wear. Therefore, appropriate maintenance or adjustments must be made based on the stress and wear conditions.

[0004] In this case, a paper-cutting device in the form of a strip-shaped lower blade and a vertically movable strip-shaped upper blade is considered. During operation, both blades experience wear. Depending on the wear and stress, the initially set cutting gap between the two blades changes. This cutting gap separates the lower blade from the upper blade, which passes perpendicularly through it, causing the strip to be cut to be drawn into the cutting gap during the cutting process. If the width of the cutting gap changes from an ideal width set relative to the strip to be cut, the cutting quality is affected, resulting in waste.

[0005] Therefore, if the width of the cutting gap changes due to wear, the cutting gap must be readjusted. In the case of known cutting equipment, this is done manually by a maintenance personnel after visually inspecting the width of the cutting gap beforehand. For this test, the personnel use an optical measuring device (also known as an inspector) to check and measure the cutting gap, thereby determining the specific gap width. To achieve gap adjustment, the lower blade is arranged horizontally, meaning it can be adjusted horizontally relative to the upper blade, which is fixed in the horizontal direction. For example, in DE 20 2013 103 082 U1, the lower blade is typically firmly located on one side of the table used to support the strip, so the table and the lower blade are adjustable. For this purpose, the table is horizontally mounted in the equipment frame and can be locked, for example, clamped, at the corresponding positions in the axial direction or against the direction of belt transport. On the side of the table opposite the lower blade, there are usually two fully rotatable adjustment devices, one on the left and one on the right, which allow for fine-tuning of axial movement. By using these adjustment devices on the corresponding sides, the longitudinal position of the table can be adjusted and corrected, thereby adjusting the cutting gap and the path from the lower blade to the upper blade. The adjusting nut is preloaded by a spring element or spring pack, which applies a specified reaction force between the table and the equipment frame. Depending on the direction of rotation of the adjusting screw, the cutter depth can be finely adjusted by adjusting the table, and the cut or cut gap can be widened or narrowed. The variation in cut gap width within this adjustment or range is typically very small, usually within the range of approximately 0.002-0.2 mm.

[0006] To detect this short movement distance, a suitable mechanical measuring device in the form of a dial indicator is used. This device has a stylus and a mechanical display, with the measuring device fixed in place on the equipment frame and the stylus positioned on the table. The corresponding table movement is detected by the probe and displayed on the dial indicator's mechanical (i.e., analog) display for maintenance personnel to read. This type of recording and continuous verification of positioning movements using a measuring device is very time-consuming and sometimes even difficult because the compactness and width of the cutting device in this area often prevent easy access to the measuring device to read the displayed values. Therefore, this type of maintenance requires considerable effort and careful planning.

[0007] Therefore, this invention provides a relatively improved cutting device based on this problem. Utility Model Content

[0008] To address the aforementioned problems, this invention provides a cutting device of the type mentioned at the beginning, comprising at least one sensor capable of detecting a sensor signal representing a measurement of the movement path of the tool holder caused by an adjustment device. The sensor signal is then transmitted to a processing device configured to determine path information values ​​indicating the movement distance based on the measurement. This path information can be displayed on a display device.

[0009] This invention therefore provides an arrangement of sensors that provide measurements in the form of electrical sensor signals. These signals represent the horizontal distance the lower blade has moved relative to the upper blade. The sensor signals are provided to a processing device connected to the sensors. This processing device processes the sensor signals using a suitable processing algorithm and, based on this, determines path information indicating the actual distance the lower blade has moved, where the lower blade is adjusted via an adjustment device. This path information describes the actual adjustment movement of the lower blade via the adjustment device. This value is then output to a display device that communicates with the processing device. Since this display device can be placed in any easily visible location where maintenance personnel can adjust the blade via the adjustment device, the adjustment process can be performed simply and efficiently.

[0010] Typically, the cutting gap is set to an ideal initial value at the factory, meaning the lower blade is placed in a defined starting position at the factory. This is done by adjusting the position of the table accordingly using an adjustment device. The table is then fixed in this starting position. If optical measuring equipment, such as the previously mentioned observation equipment, is used for optical inspection, the area of ​​the cutting gap can be seen and the gap can be measured. It will be found that the cutting gap no longer has the defined initial width, meaning the two blades are no longer in their starting positions, and maintenance personnel will make adjustments. Then, the sensor provides appropriate information for the adjustment movement, detecting the corresponding movement path starting from the given starting position of the lower blade or the table, which, from the sensor's perspective, is 0. This movement path reduces the cutting gap toward the upper blade or increases the cutting gap in the opposite direction. The actual gap width is not measured and displayed; instead, only the actual movement path of the lower blade or the position of the table at the start of the adjustment process is recorded, which is used as the sensor's 0 position. Because the adjustment is easier to monitor, this makes the adjustment process much easier for maintenance personnel, and the electronic or digital detection of the movement path by the sensor also increases accuracy, allowing for adjustments even at the micrometer level, and with high precision.

[0011] Imagine that sensor signals can be automatically recorded at the start of an adjustment movement initiated by the regulating device. If an adjustment is made, signal recording and path detection are initiated immediately upon the start of the movement, with corresponding sensor signals being continuously recorded in real time, and the processing device determining and outputting path information in real time. Alternatively, sensor signals can be recorded when a user issues a command through the processing device. The user enters a command on the processing device or a corresponding input device, such as a touchscreen display, indicating that they want to execute an adjustment process. This activates the sensors, providing the corresponding sensor signals and performing path measurement.

[0012] It is conceivable that each adjustment process can only be performed within a limited, predefined adjustment range. This is to prevent excessively large travel ranges from being accidentally set and damaging the blade system upon restart. For example, the maximum adjustment path during the adjustment process can be limited to a maximum of 0.06 mm. To avoid exceeding this maximum adjustment path, the processing device compares the sensor signal or determined path information with a reference signal or reference information and displays the comparison result on a display device. This maximum adjustment path can serve as a reference for continuous comparison of the actual adjustment path. For example, if the actual adjustment path matches the reference value, a corresponding alarm signal can be issued, indicating that further adjustment should be interrupted. The processing device can directly compare the sensor signal with the reference signal, or it can compare the determined path information with the reference value, i.e., the maximum permissible adjustment path.

[0013] The determined path information is then output as a numerical value to the display device. Because the sensor continuously records the adjustment movement, the displayed value is constantly updated in real time, allowing maintenance personnel to accurately detect the degree of adjustment and whether the adjustment target has been met. As mentioned earlier, the adjustment path is typically very small, sometimes within the micrometer range. The numerical value can also be associated with color-coded indications. For example, if the maximum adjustment limit is set to 0.06 mm, the display can be highlighted in green as long as the actual adjustment path remains less than 0.06 mm. For example, when the adjustment limit of 0.06 mm is reached, the display can switch to a red background. Furthermore, when the adjustment path reaches 0.05 mm, the display can also switch to yellow to immediately warn maintenance personnel before the adjustment limit is reached. Therefore, a traffic light system with additional color coding can be provided.

[0014] As an alternative to displaying specific numerical values, path information can also be represented graphically, for example as a bar chart with scales ranging from 0.0 mm to 0.06 mm, and labeled with indicators to adjust the scale values. Of course, other charts for displaying variable path information can also be considered.

[0015] Alternatively, the processing device can determine and display the required cutter movement length to modify the cutting gap. The device can also use a suitable processing algorithm to determine the precise adjustment path to adjust the cutting gap to the ideal width for cutting the strip. Before the adjustment process begins, maintenance personnel input the determined actual cutting gap width into the input device via optical inspection and measurement. The processing device then calculates the optimal cutting gap width, taking into account material parameters such as strip type (textile cord or steel cord), strip thickness, and strip condition. Based on the input actual width value and the target width value, the required adjustment path is determined and displayed. Maintenance personnel can then make adjustments under continuous sensor monitoring to ensure the desired target value is achieved.

[0016] In this improvement, the adjustment mechanism may include two independent adjustment devices coupled to the tool holder at their side ends and capable of operating independently. As previously mentioned, a lateral adjustment device with two adjusting nuts is typically used for manual operation, allowing linear movement of the tool holder and the lower tool. In this case, it is useful to assign a separate sensor to almost each mechanical adjustment device via an adjusting nut, enabling precise measurement of the adjustment path at both locations. This allows for high-precision, individual adjustments at both end regions, as well as the setting or correction of a defined tilt around the vertical axis via two independent adjustment devices with slightly different adjustments.

[0017] The adjustment device itself can be a spindle with a manually operated adjusting nut, or it can be driven by a spindle driven by an adjustment motor. In the manual operation case, the adjusting nut is manually operated using appropriate tools. The adjusting nut is connected to the spindle via a fine thread, thus enabling high-precision positioning. Alternatively, a spindle drive with a spindle and a spindle nut, driven by an adjustment motor, can also be used, also with a fine thread to allow for precise adjustment. Therefore, different designs of suitable adjustment devices can be considered, designed to achieve high-precision adjustment paths within the micrometer range.

[0018] As mentioned earlier, it is advantageous to have two sensors that are horizontally spaced apart from each other. These sensors are positioned along the tool holder and horizontally spaced apart from each other along its sides. Each sensor provides a separate sensor signal and is evaluated independently, thus allowing for precise path adjustment in both positions. This also makes it possible to achieve high-precision individual adjustments on both sides, for example, moving one adjustment by 0.02 mm and the other by 0.03 mm, thus allowing the lower tool to be placed simultaneously on both sides in a horizontal manner, or, if necessary, with minimal tilt around the vertical axis.

[0019] Each sensor is preferably designed as a contact pin, comprising a housing and a pin movable relative to the housing. Thus, the pin can move in and out of the housing, depending on the direction of displacement. Each slight relative movement of the pin with the housing generates a position-specific sensor signal, i.e., appropriate measuring or position detection components within the housing precisely determine the actual position of the pin relative to the housing. The sensor signal is then transmitted to a processing device for further processing.

[0020] Alternatively, each sensor can be an optional sensor comprising a housing with a unit that emits a scanning beam and detects reflected light. While the contact pin performs a mechanical scan, the photo-optical sensor performs a non-contact scan to determine the path. The sensor has a transmitter and receiver within the housing through which it emits a scanning beam directed at the component to be moved and detects the reflected radiation, generating an actual sensor signal based on this, which is then processed by a processing device.

[0021] The housing can be attached to the tool holder, the pin can rest against the device frame, or the scanning beam can be aligned with the device frame. In this case, the housing will move when the pin is securely positioned on the device frame, or the scanning beam will align with and position the device frame. Of course, the setup can also be reversed.

[0022] After adjustment, the tool holder, i.e., the table, must be secured back to the assumed end position, thus fixing the assumed position for the tool drop. For this purpose, suitable mechanically or hydraulically operated clamping devices are provided. These devices must be easily released to accommodate the adjustment process, and also easily re-clamped to ensure a sufficiently secure lock.

[0023] In addition to the cutting device itself, this utility model also relates to a method for adjusting the cutting gap between the upper and lower blades of a cutting device for cutting strip-shaped materials, particularly an adhesive cord, wherein the cutting device includes a strip-shaped lower blade and a strip-shaped upper blade, the upper blade moving vertically relative to a fixed-position lower blade, wherein the lower blade is connected to a blade holder, the blade holder being supported linearly and horizontally on a device frame and linearly movable by an adjustment device, such that the position of the lower blade relative to the upper blade can be changed, and a given cutting gap between them can be adjusted. A device for detecting the horizontal movement of the lower blade relative to the upper blade is also provided. The method is characterized by the device including at least one sensor that detects a sensor signal representing a measurement of the blade holder's movement path implemented by the adjustment device; the sensor signal can be transmitted to a processing device that determines path information indicating the movement path based on the measured value, wherein the path information can be output to a display device.

[0024] The system can provide sensor signals that are automatically detected by the adjusting device at the start of the adjustment; that is, the detection process starts automatically and immediately when the adjustment begins. Alternatively, the system can provide sensor signals detected when the user issues a detection command through the processing device. In this case, the start of signal detection is triggered by the command input.

[0025] In addition, the processing device can compare sensor signals or determined path information with reference signals or reference information and display the comparison results on a display device.

[0026] The path information displayed to maintenance personnel is best output as a numerical value on the display device. This value can also be correlated with color information to indicate whether an effective adjustment path is within defined allowable control limits. Alternatively, the path information can be output as a graphical representation.

[0027] In addition, the processing equipment can determine the required movement length through an adjustment device to adjust the cutting gap and adjust the cutting depth, which is then output at the display device.

[0028] The sensor may also include a contact pin, including a housing and a pin movable relative to the housing, or an optical sensor including a housing with a scanning beam emitter and a reflecting light receiver. Attached Figure Description

[0036] Figure 9 A partial view of the cutting device with a blade holder is shown, along with the fixing device assigned to it and the adjustment device of the second embodiment. Detailed Implementation

[0037] Figure 1 A cutting device 1 in the form of a paper cutter according to the present invention is shown. The cutting device 1 is used to cut strips of material, such as textile cord or steel cord, from a feedstock. The cutting device 1 includes a frame 2, also referred to as a machine frame, on which a blade holder 3 in the form of a table 4 is mounted. The blade holder 3 can float or move horizontally, as indicated by double arrow P1. A strip-shaped lower blade 5 is mounted on the blade holder 3. Furthermore, an upper blade 6 is provided, mounted on another blade holder 7, which can be guided on the frame 2 by a guide device (not shown in detail) and can move vertically, as indicated by double arrow P2. A cutting gap S is formed between the upper blade 6 and the lower blade 5. The width of the cutting gap S can be adjusted by horizontally moving the blade holder 3 (i.e., the table 4) to change the position of the lower blade 5. For this purpose, an adjustment device 8 is provided, which will be described in more detail below. These adjustment devices 8 can be operated manually by screwing together the corresponding adjustment nuts running on the fine-threaded spindle, or by adjusting the motor-driven lead screw, which also has fine threads.

[0038] To accurately capture such adjustment movements, at least one sensor 9, preferably in the form of a touch pin 10, is provided. This sensor detects an electrical sensor signal representing a measurement of the movement path of the tool holder 3 obtained through the adjustment device 8, thereby representing a measurement of the movement path of the down-cutting tool 5 obtained through the adjustment device 8. This sensor signal is transmitted to a processing device 11 connected to the sensor 9 or the touch pin 10. Based on the sensor signal, the processing device 11 uses an appropriate evaluation algorithm to determine path information indicating the movement path, wherein the path information is output on a display device 12, such as a monitor. The person making the adjustment can monitor the display device 12 in an optimal and convenient manner while making adjustments via the adjustment device 8. This ensures not only accurate capture of the movement path electronically or digitally, but also comfortable operation and path control.

[0039] To determine whether the lower blade 5 needs adjustment and thus the width of the cutting gap S, the cutting gap S is typically optically inspected, i.e., optically measured, by a person. For this purpose, the cutting gap S is optically observed and measured by a person with suitable optical measuring instruments (hence also called an inspector). This is used to determine whether and, if so, to what extent the cutting gap S should be corrected, and therefore, by which path the lower blade 5 should be adjusted. If the cutting gap S is too large, the adjustment moves the lower blade 5 closer to the upper blade 6, while if the cutting gap S is too small, the adjustment deviates the lower blade 5 from the upper blade 6, even to the point of edge overlap between the upper blade 6 and the lower blade 5. Once the need for adjustment is determined, the fixing device 13, preferably a mechanically or hydraulically operated clamping device, is released. The fixing device 13 secures the blade holder 3 in a fixed position on the equipment frame 2. After release, the lower blade 5 is adjusted by the adjusting device 8. Thus, the movement path of the blade holder 3 is continuously recorded by the sensor 9 and the actual movement path or adjustment process is displayed in real time on the display device 12, allowing the operator to control the adjustment process very precisely and determine when the desired target position of the lower blade 5 is reached. Then the adjustment process is completed, and the tool holder 3 is fixed again by the fixing device 13, thereby fixing the relative position of the lower tool 5 and the upper tool 6.

[0040] Figure 2 A top view of the cutting device 1 is shown, which includes the device frame 2, the knife holder 3 in the form of a table 4, and the lower knife 5. The upper knife 6 is also indicated, and the fixing devices 13 provided on both sides are also marked.

[0041] Adjustment devices 8 are also shown, implemented as two independent adjustment devices 14. The adjustment devices 14 are arranged on both sides of the tool holder 3 and are manually operated in the initial example shown. Each adjustment device provides a fine-threaded spindle 15, and each spindle has an adjusting nut 16, which must be manually operated to move the tool holder 3 linearly and horizontally. The direction of movement (as shown by arrows P5 and P6) changes depending on the direction of rotation (which can be clockwise or counterclockwise, as indicated by arrows P3 and P4).

[0042] Since each adjustment device 14 can be operated independently, individual bilateral adjustments can be made. This allows the tool holder 3 to tilt slightly around the vertical axis so that the angle between the two cutting edges of the lower tool 5 and the upper tool 6 (within a few arcseconds or minutes) can be precisely set or compensated, thus allowing the edges to be aligned parallel again.

[0043] Each adjustment device 14 is assigned a sensor 9 in the form of a contact pin 10 so that the motion path can be captured or the corresponding sensor signal can be detected at both adjustment positions. Both sensor signals are transmitted to a common processing device 11 to determine path information. In this case, the processing device 11 preferably calculates and outputs two separate path values ​​corresponding to each adjustment device 14.

[0044] Figure 3 A similar cutting device 1 is shown, as before. Figure 2 As shown and explained. The only difference is that the regulating devices 8 (i.e., the two regulating devices 14) are electrically powered, i.e., automatically operated. Each regulating device 14 includes a separately controllable regulating motor 17 with a distributed gearbox 18. The regulating devices 14 also include a screw drive 19 for each threaded rod, wherein the spindle nut or the spindle itself is driven via the regulating device 17 and the gearbox 18. Depending on the direction of rotation of each motor (again shown by arrows P3 and P4), the movement is also performed in the direction of the belt conveyor (see arrow P5) or against the direction of the belt conveyor (see arrow P6).

[0045] Figure 4 A partial view of the cutting device 1 is shown, including a portion of the tool holder 3 (such as the table 4) and the device frame 2. As indicated by double arrow P1, the tool holder 3 is horizontally movable relative to the fixed device frame 2, and either the tool holder 3 or the table 4 is guided by suitable guide rails. A sensor 9, in the form of a contact pin 10, is also shown, comprising a housing 20 and a pin 21 that can be moved in and out of the housing 20. Two such sensors 9 can be used, as described above. A suitable detection device for capturing the position or movement of the pin 21 is integrated in the housing 20, providing a sensor signal describing the path of movement. This signal is transmitted to the processing device 11 via communication line 22. The housing 20 is connected to the tool holder 4 (in this example, the table 4) via a mounting bracket 23, while the tip of the pin 21 rests against the bearing surface 24 of the device frame 2. If the table 4 is displaced relative to the fixed device frame, the pin 21 is pushed into the housing 20, or, since it is spring-loaded, pushed out according to the direction of movement, for example by a spring provided in the housing. Any pin movement, however minute, is detected and transmitted to the processing device 11 via a corresponding sensor signal. The processing device 11 then determines the corresponding path information, which is output to the display device 12.

[0046] Figure 5-7 An example of the cutting device 1 is shown, which includes a blade holder 3 or a table 4 comprising a lower blade 5, a device frame 2, an additional blade holder 7 and an upper blade 6, and a cutting gap S. A display device 12 is also shown, on which the corresponding path information 25 determined by the processing device 11 is reproduced in graphical form.

[0047] exist Figure 5 In the positioning configuration shown, the cutting gap S is given, meaning that the upper blade 6 moves laterally next to the lower blade 5, and is separated by the cutting gap S during lowering. The sensor 9 is shown, also represented as a contact pin 10. Figure 5-7 The position adjustment process is shown, where, from Figure 5 The cutting gap shown begins with the lower blade 5 moving to overlap with the upper blade 6, which is obviously not the case in actual operation. This is only to explain the adjustment process itself and the changes in position-related path information shown in graphical representation 25.

[0048] As mentioned above, Figure 5 The initial state of the given cutting clearance S is displayed. If adjustment begins now, sensor 9 will either automatically activate immediately at the start of the first infinitesimal motion or immediately and continuously provide corresponding sensor signals, resulting in the determination of path information, which is displayed as a graphical representation 25. Alternatively, the measurement operation can be initiated by inputting a corresponding command, which can be issued by the user, for example, through a display device 12 designed as a touchscreen.

[0049] For example, a bar representation 26 is shown, continuously displaying the actual movement path. Bar representation 26 has scales 27, where the lowest scale value 28 is the zero point, and the highest scale value 29 is the maximum movement value. Assuming the maximum movement path is 0.06 mm, then in this case, the lowest scale value 28 is 0.0 mm, and the highest scale value 29 is 0.06 mm. The scales can be increased in increments of 0.01 mm. A marker 30 is also shown, indicating the actual movement path. Here, marker 30 is displayed as an arrow because the sorting process has just begun, and it eventually points to the zero point, i.e., the lowest scale value 28.

[0050] Assume the tool holder 3 moves to the left, meaning the lower tool 5 moves to the upper tool 6. This reduces the cutting gap S, or as... Figure 6 As shown, the final setting is 0, meaning there is almost no clearance when the upper cutter 6 moves past the lower cutter 5. This adjustment movement is shown in graphic representation 25. Marker 30 has moved upwards and now, due to the 0.03 mm adjustment, finally points to the middle of scale 27. Pin 21 is clearly being gently pushed into housing 20.

[0051] If further adjustments are made in this direction of movement, the lower blade 5 and the upper blade 6 overlap and push, as shown in Figure 31. The pin 21 is further pushed into the housing 20. This position is also precisely recorded and displayed in the graphic representation 25. Clearly, the mark 30 has moved further upwards, pointing to the highest scale value 29, indicating a maximum allowable adjustment of 0.06 mm. Therefore, the person making the adjustment can immediately and clearly understand that the maximum adjustment has been made and the adjustment process must be completed. The achievement of the maximum adjustment can also be associated with a corresponding color signal, for example, the display device 12 lighting up or flashing red, or the mark 30 lighting up or flashing red, thus issuing a warning signal indicating that the maximum adjustment has been reached. For example, a traffic light system displaying color information can also be envisioned. For example, when adjusting by 0.0 mm - 0.05 mm, the display device is green; when the movement exceeds 0.5 mm, it turns yellow; and when the maximum adjustment of 0.06 mm is reached, it turns red. This means that the operator will also receive a color signal.

[0052] Although the example described shows a graphical representation 25 to indicate path information, it is certainly conceivable to determine and display specific numerical values ​​indicating the actual movement path as path information. Therefore, instead of the bar representation 26, corresponding, continuously varying values ​​would be displayed, ultimately starting from 0.0 mm - 0.06 mm if this is the maximum path upper limit. Of course, corresponding color information as described above could also be provided here.

[0053] It is conceivable that the processing device 11 is also equipped with a tool for determining the motion path to be set to achieve the ideal width of the cutting gap S. This motion path can also be additionally displayed as a numerical value on the display device 12. As previously described, the operator pre-determines the current width of the cutting gap S using an optical measuring device. This value can be input into the processing device 11 by the user, for example, through the display device 12. The device then calculates the ideal gap width and the necessary movement path to achieve that ideal gap width using an appropriate algorithm, and then displays the value. In this way, the system can provide this information in addition to allowing the operator to manually determine the required motion path. Because the actual motion path is continuously recorded, the operator can now precisely see when the required movement is completed.

[0054] Figure 8 A side view of the cutting device 1 is shown, illustrating the first embodiment. The blade holder 3 is again shown in the form of a table 4, which is movable or floating and can be fixed or clamped in position by corresponding fixing devices 13. The lower blade 5, the upper blade 6, and the cutting gap S are also shown.

[0055] The device frame 3 and sensor 9, again in the form of contact pin 10, are also shown and connected to the tool holder 3 or table 4 via mounting bracket 23. An adjustment device 8, or one of two adjustment devices 14, is also shown in the figure; these are shown here as manual adjustment devices 8 with corresponding adjusting nuts 16. Each of the adjustment devices 14 includes a spring pack 32, which is supported on the device frame 3, and the table 4 can move against it. The spring pack 32 is used to generate a preload force opposite to the movement of the lower tool 5 along the direction of the upper tool 6; therefore, when the lower tool 5 moves closer to the upper tool 6, the system is preloaded by the adjusting nut 16 against the spring pack 32.

[0056] Figure 9 Another partial view of the cutting device 1 is shown, where the knife holder 3 in the form of a table 4 and the corresponding fixing device 13 for securing the table 4 to the device frame 3 are again shown. The lower knife 5, the upper knife 6, and the cutting gap S are also shown. In this embodiment, the sensor 9, again in the form of a contact pin, is arranged below the table 4 via a mounting bracket 23. It should be noted that fastening elements other than such threaded fasteners 23 can also be used independently in all embodiments for positioning and securing the corresponding sensor 9.

[0057] An adjustment device 8 is also provided here, wherein only one adjustment device 14 is shown again, which must be manually operated and has a corresponding adjustment nut 16.
