Description

Technical Field

[0001] The invention relates to a cutting device for severing non-woven sections of threads or filaments woven into a textile strip. The invention also relates to a method for severing non-woven sections of threads or filaments woven into a textile strip. Background Art

[0002] In the textile industry, labels are used to identify clothing or other textiles. Therefore, labels are integrated into clothing (e.g., in standardized locations). The batch number, manufacturer's name, and some further information about the product are usually printed on the label and can similarly be written by a human. Since clothing or other textiles are mostly batch products, they are produced in highly automated batch production.

[0003] In modern, highly automated systems, radio frequency identification (RFID) enables manufacturers and retailers to process and / or track textiles digitally. Tiny antenna filaments woven into the tags are able to communicate via radio frequency. Consequently, storing the tags, including the antenna filaments, as quasi-annular textile strips wound around a tape reel is problematic. Therefore, each tag is cut from the quasi-annular textile strip into which the quasi-annular antenna filaments are woven and then integrated into the garment. This results in loose ends of the antenna filaments at each tag, which can negatively impact the sensitive RFID functionality. The prior art does not offer a solution for adequately severing the tags and antenna filaments from the quasi-annular textile strip.

[0004] Document WO 2005 / 071605 A2 discloses, for example, a textile material comprising a high-frequency transponder comprising a circuit module and an antenna connected to the circuit module and set to an operating frequency. Document DE 102011106648 A1 discloses a portable data device comprising a device for storing and processing data and an antenna for transmitting energy and data, the antenna being connected to the device. Summary of the Invention

[0005] Aspects of the present invention may provide a solution for severing non-woven segments of metallized threads or filaments that are alternately woven / non-woven in the fabric of a quasi-endless textile strip.

[0006] According to a first aspect of the present invention, a cutting device for cutting off non-woven sections of threads or filaments woven in a textile strip comprises: a strip conveying table configured to convey a textile strip having metallized threads or filaments woven / non-woven in a quasi-annular manner in the fabric of the strip; at least two cutting assemblies spaced apart from each other along the conveying direction of the textile strip, the at least two cutting assemblies configured to simultaneously perform a cutting action for cutting the non-woven sections of the metallized threads or filaments from the fabric of the strip; and at least two sliding spacers spaced apart from each other along the conveying direction of the textile strip, the at least two sliding spacers each connected to a corresponding cutting assembly of the at least two cutting assemblies, contacting the surface of the strip and configured to slidably move between the metallized threads or filaments and the fabric of the strip at the edge of the non-woven section to facilitate the cutting action of the at least two cutting assemblies.

[0007] According to a second aspect of the invention, a method for cutting a non-woven section of threads or filaments woven in a textile strip comprises the following steps: providing a cutting device, in particular a cutting device according to the first aspect of the invention, and a textile strip, wherein the textile strip has metallized threads or filaments woven / non-woven in a quasi-annular manner in the fabric of the strip; conveying the textile strip in the strip conveying table along the conveying direction; stopping the strip after conveying the strip a calculated travel amount; causing the cutting assembly and the sliding spacer to move from a first position to a second position, wherein the sliding spacer slides between the metallized threads or filaments and the fabric of the strip at the edge of the non-woven section, thereby lifting the metallized threads or filaments away from the fabric; and simultaneously performing a cutting action for cutting the non-woven section from the fabric of the strip at the edge of the non-woven section of the metallized threads or filaments.

[0008] According to a third aspect of the present invention, a cutting device for cutting non-woven sections of fibers woven in a fabric strip comprises: a strip conveying table, wherein the strip conveying table is configured to convey a fabric strip having conductive fibers woven / non-woven in a quasi-annular manner in the fabric strip; and at least two tool holding structures, each of the at least two tool holding structures having a scissors assembly and a fiber separator, wherein the tool holding structure is movably connected to the strip conveying table; wherein the scissors assemblies of the at least two tool holding structures are arranged parallel to the conveying direction of the fabric strip and are configured to simultaneously perform a cutting action for cutting the non-woven section of the conductive fiber from the fabric strip; wherein the fiber separator is configured to slidably separate the conductive fiber from the fabric strip at the edge of the non-woven section to facilitate the cutting action of the scissors assembly.

[0009] According to the fourth aspect of the present invention, a method for cutting a non-woven section of fibers woven in a fabric strip comprises the following steps: providing a cutting device, in particular a cutting device according to the first aspect of the present invention, and a fabric strip, wherein the fabric strip has conductive fibers woven / non-woven in a quasi-annular manner in the fabric strip; conveying the fabric strip in the strip conveying table along the conveying direction; stopping the fabric strip after conveying the fabric strip a calculated travel amount; causing the tool holding structure to move from a first position to a second position, wherein the fiber separator slides between the conductive fibers and the fabric strip at the edge of the non-woven section, thereby separating the conductive fibers from the fabric strip; and simultaneously performing a cutting action for cutting the non-woven section from the fabric strip at the edge of the non-woven section of the conductive fibers.

[0010] The basic concept of the present invention is to simultaneously cut metallized threads or filaments, such as antenna filaments, at the edges of their non-woven sections. Since the strips are typically manufactured in a quasi-annular manner, the metallized threads or filaments are also woven / non-woven into the strip and contact the fabric of the strip in the non-woven sections, which are transported on the strip conveyor table in the conveying direction. Therefore, the metallized threads or filaments need to be separated from the fabric to perform the cutting action, as the fabric of the strip should not be touched or even damaged by the cutting components. The separation of the metallized threads or filaments from the fabric of the strip in the non-woven sections is achieved by a sliding spacer that slides between the metallized threads or filaments and the fabric. The further the metallized threads or filaments are separated, the more the sliding spacer slides under the metallized threads or filaments. The metallized threads or filaments are fixed to the strips at the edges, with the sliding spacer sliding under the metallized threads or filaments anywhere between the edges, preferably close to the edges.

[0011] A particular advantage of the solution according to one aspect of the invention is that the non-woven sections of the metallized threads or filaments are severed from the strip, leaving only very short loose ends of the metallized threads or filaments at the edges of the woven sections. Since the metallized threads or filaments that remain in the fabric in the woven sections communicate via radio frequency, it is very important not to leave long loose ends, as undefined loose ends of the metallized threads or filaments could interfere with the radio frequency signal.

[0067] Figure 1 and Figure 2 A schematic illustration of a textile strip 4 is shown, which has metallized threads or filaments 5 woven / non-woven in a quasi-annular manner in the fabric of the strip 4 .

[0068] The textile strip 4 is produced in a quasi-annular shape. The metallized threads or filaments 5 are also produced in a quasi-annular shape and woven into the fabric of the strip 4, so that the metallized threads or filaments 5 are antennas or at least have the properties and functions of an antenna.

[0069] Specifically, Figure 2 A textile strip 4 is shown with cut non-woven segments 52 of metallized threads or filaments 5. The non-woven segments 52 are cut at their edges 50, where the woven segments 51 of the metallized threads or filaments 5 begin and end. The woven segments 51 of the metallized threads or filaments 5 are woven into the textile strip 4 in any pattern, preferably in a serpentine pattern. For example, the metallized threads or filaments 5 are woven into the textile strip 4 so that the non-woven segments 52 and the woven segments 51 alternate along the quasi-annular strip 4 for a predetermined length L, wherein the predetermined length L is the length in the longitudinal direction of the quasi-annular strip 4 between the edge 50 of the starting non-woven segment 52 and the edge 50 of the ending woven segment 51, as shown. Figure 2 Therefore, the predetermined length L includes the lengths of the woven section 51 and the non-woven section 52 in the longitudinal direction of the quasi-annular strip 4, and the predetermined length L is constant at the textile strip 4 according to the present embodiment.

[0070] exist Figures 3 to 5 , a cutting device 100 according to an embodiment of the present invention is schematically illustrated. Figures 3 to 5 The same components and features of the cutting device 100 are described only once with respect to one of the figures. Unless otherwise described, these components and features can be included and combined in every embodiment of the present invention.

[0071] Figure 3 An isometric illustration of a cutting device 100 for severing non-woven sections 52 of threads or filaments 5 woven into a textile strip 4 is shown according to one embodiment of the present invention.

[0072] The cutting apparatus 100 includes a strip transport table 1 , at least two cutting assemblies 2 and at least two sliding spacers 3 .

[0073] The strip conveying station 1 is configured to convey a textile strip 4 having a quasi-annular woven / non-woven fabric on the strip 4 (particularly Figure 1 and Figure 2The metallized threads or filaments 5 in the fabric of the strip 4) of the textile strip 4 are provided. In order to convey the textile strip 4, the strip conveyor platform 1 can have a strip conveyor drive configured to convey the strip 4 along a conveying direction A. The strip conveyor drive can be configured as an electric motor, a fluid motor or an internal combustion engine that drives the strip 4 by a rotary or linear drive device, in particular as a conveyor belt system configured with a flat belt driven between at least two cylindrical rollers. In addition, the strip conveyor platform 1 can have a base that stands on the floor and supports at least some components of the strip conveyor platform 1.

[0074] The at least two cutting assemblies 2 are spaced apart from each other along the conveying direction A of the textile strip 4, and the at least two cutting assemblies 2 are configured to simultaneously perform a cutting action for severing the non-woven section 52 of the metallized thread or filament 5 from the fabric of the strip 4. The cutting assemblies 2 can be kinematically connected via a tool connection assembly 10, in particular a spindle or shaft, so that the position of the cutting assemblies 2 and / or the distance between them can be adjusted along an axis parallel to the conveying direction A of the strip 4. The tool connection assembly 10 is capable of manually or automatically adjusting the distance between the cutting assembly 2 and the edge 50 of the metallized thread or filament 5, wherein the cutting assembly 2 is used to cut the metallized thread or filament 5. Alternatively or in addition, the tool connection assembly 10 is configured to manually or automatically change the position of the cutting assembly 2 along an axis parallel to the conveying direction A of the strip 4. Thus, according to Figure 3 The embodiment shows a segmented threaded spindle, wherein each segment of the threaded spindle guides one of the at least two cutting assemblies 2, and wherein the threads of the two segments of the threaded spindle are arranged in opposite directions, so that by rotating the spindle, the cutting assemblies 2 are moved closer together or away from each other in the conveying direction A. In order to change the position of the cutting assemblies 2, the spindle can be supported movably in the conveying direction A as well as fixedly, for example in shaft bearings, which allow the spindle to be moved in its longitudinal direction.

[0075] The at least two sliding spacers 3 are spaced apart from each other along the conveying direction A of the textile strip 4, and the at least two sliding spacers 3 are each connected to a corresponding cutting assembly of the at least two cutting assemblies 2, contact the surface of the strip 4 and are configured to be slidably movable between the metallized wires or filaments 5 and the fabric of the strip 4 at the edge 50 of the non-woven section 52 to facilitate the cutting action of the at least two cutting assemblies 2. Similar to the cutting assembly 2, the sliding spacers 3 can be kinematically connected via a tool connecting assembly 10, in particular a spindle or shaft, so that the position of and / or the distance between the sliding spacers 3 can be adjusted along an axis parallel to the conveying direction A of the strip 4. Optionally, the sliding spacers 3 can be kinematically connected via a second tool connecting assembly that is kinematically independent of the tool connecting assembly 10, which second tool connecting assembly can be connected to the cutting assembly 2. In Figure 3 In the embodiment, the cutting device 100 further includes a support structure 11 in which the cutting assembly 2 and the sliding spacer 3 are supported, wherein each support structure 11 supports one of the at least two cutting assemblies 2 and one of the at least two sliding spacers 3. The support structure 11 can be directly or indirectly connected to the tool connection assembly 10.

[0076] like Figure 3 As shown, the cutting device 100 can further include a sensor 7 configured to sense a reference position of the metallized thread or filament 5 in the fabric. The sensor 7 is in particular configured as a capacitive sensor, an inductive sensor, a magnetic field sensor or an optical sensor. The sensor 7 is preferably located upstream of the cutting assembly 2 and the sliding spacer 3 relative to the conveying direction A of the strip 4. The sensor 7 can be designed to sense a specific point in the structure of the metallized thread or filament 5. The specific point in the structure of the metallized thread or filament 5 can be a starting point for calculating the amount of travel required to make the textile strip 4 move along the conveying direction A until the strip 4 stops in a certain position along the conveying direction A relative to the cutting assembly 2 and the sliding spacer 3, where the non-woven segment 52 can be severed from the fabric of the strip 4.

[0077] Furthermore, the cutting device 100 may include a strip transport drive configured to transport the strip 4 in a transport direction A by an amount based on a sensed reference position of the metallized threads or filaments 5 in the fabric and a predetermined length L of the woven / non-woven section of the metallized threads or filaments 5 in the fabric of the strip 4. The predetermined length L may be as follows: Figure 2 The length of the non-woven section 52, the length of the woven section 51 only, or any other length that serves as a characteristic for positioning the edges 50 of the sections 51, 52 of the metallized wire or filament 5 of the textile strip 4 along the conveying direction A relative to the above-mentioned cutting assembly 2 and sliding spacer 3.

[0078] The cutting device 100 may further include at least two textile strip reels 8, which are configured to tighten the textile strip 4, wherein at least one of the at least two textile strip reels 8 is positioned before the cutting assembly 2 and the sliding spacer 3 and at least one of the at least two textile strip reels 8 is positioned after the cutting assembly and the sliding spacer relative to the conveying direction A of the strip 4. The textile strip reel 8 can be configured in the form of a cardboard sleeve, a spool or a cylinder. The textile strip reel can be pivotally mounted to the strip conveying table 1, wherein the rotation axis of the strip reel 8 is perpendicular to the conveying direction A.

[0079] Optionally, the cutting device 100 may include a quality assurance device 9 for ensuring that the non-woven section 52 of the metallized thread or filament 5 is completely severed from the fabric, the quality assurance device 9 being positioned downstream of the cutting assembly 2 and the sliding spacer 3 with respect to the conveying direction A of the strip 4. The quality assurance device 9 may be configured to visually inspect the surface of the textile strip 4 after the cutting action to find defects in the strip 4. The defect may be that the non-woven section 52 of the metallized thread or filament 5 has not been severed from the strip 4 but is still attached to the strip 4, or that the woven section 51 of the metallized thread or filament 5 is incorrect.

[0080] Furthermore, the cutting device 100 may have an air flow generator 12 configured to generate an air flow through the strip conveying table 1. Thus, the air flow generator 12 may be configured as an extraction system (e.g. Figure 3 ), and is arranged adjacent to the strip conveying table 1 with respect to the conveying direction A and opposite to the cutting assembly 2 and the sliding spacer 3 relative to the textile strip 4.

[0081] Figure 4 A further embodiment of the present invention is shown Figure 3 A top view of the cutting device 100 is shown.

[0082] according to Figure 4 , along the conveying direction A of the web 4, the sliding spacers 3 can be positioned closer to each other than the distance at which the cutting assemblies 2 can be positioned relative to each other. Thus, the maximum distance between the two illustrated cutting assemblies 2 along the conveying direction A is the length of the non-woven segment 52. Furthermore, the cutting assemblies 2 and the sliding spacers 3 can be arranged parallel to each other and transverse to the conveying direction A of the web 4.

[0083] The cutting assembly 2 and the sliding spacer 3 can have a first position in which the strip 4 can be transported along the transport direction A. In this first position, when the strip 4 is transported along the transport direction A, the sliding spacer 3 contacts the fabric of the strip 4 at a line of the strip 4 that is laterally displaced from the metallized threads or filaments 5 relative to the transport direction A, in particular by about 2 mm, said alignment substantially corresponding to the transport direction A of the non-woven section 52.

[0084] The cutting assembly 2 and the sliding spacer 3 can further have a second position in which the cutting action is performed by the cutting assembly 2. Preferably, in the second position, the sliding spacer 3 can also contact the fabric of the strip 4, but is not limited thereto and can also be positioned laterally to the strip 4 so as not to contact the fabric of the strip 4. In this second position, the strip 4 is stopped and the sliding spacer 3 is positioned between the non-woven section 52 of the metallized thread or filament 5 and the fabric of the strip 4, wherein the metallized thread or filament is vertically displaced from the strip 4 so as to be cut by the cutting assembly 2 without the cutting assembly 2 contacting the fabric of the strip 4.

[0085] The travel of the cutting assembly 2 and / or the sliding spacer 3 from the first position to the second position is substantially linear and transverse to the conveying direction A of the strip 4. Therefore, the cutting device 100 can have a travel drive 6, in particular a pneumatic cylinder, a hydraulic cylinder or an electromechanical cylinder, which is coupled to the cutting assembly 2 and is configured to drive at least one or each of the cutting assemblies 2 along the travel path by an oscillating motion. Alternatively or additionally, the travel drive 6 can be coupled to the sliding spacer 3 and configured to drive at least one or each of the sliding spacers 3 along the travel path by an oscillating motion. In addition, a plurality of travel drives 6 can be provided to allow each or multiple groups of cutting assemblies 2 and sliding spacers 3 to travel kinematically and / or in time independently of one another.

[0086] The cutting device 100 may further comprise pins 13 configured to guide the strip 4 on the strip transport table 1 . Figure 4 A plurality of pins 13 are shown detachably connected to the strip conveyor table 1 , wherein the pins 13 are configured to be inserted into corresponding slots positioned in series along the conveying direction A. Specifically, the pins 13 are inserted into these slots upstream and / or downstream of the cutting assembly 2 and the sliding spacer 3 along the conveying direction A, such that the cutting assembly 2 and the sliding spacer 3 cannot collide with the pins 13 when the second position of the cutting assembly 2 and the sliding spacer 3 positions the pins outside the strip 4 .

[0087] Figure 5 1 shows a further embodiment of the present invention, viewed along the conveying direction A of the textile strip 4. Figure 3 100 is a side view of the cutting device 100.

[0088] The travel drive 6 may also be coupled to the support structure 11 for traveling the support structure 11 supporting the cutting assembly 2 and the sliding spacer 3 between the first position and the second position.

[0089] according to Figure 5In an embodiment, the air flow generator 12 is configured as a nozzle arranged above the cutting assembly 2 and the sliding spacer 3, wherein the head of the nozzle 12 is designed and oriented to generate an air flow that flows through the strip conveying table 1 to blow away the sections of the metallized wire or filament 5 severed during the cutting action.

[0090] Furthermore, the support structure 11 can be configured to mechanically support the cutting assembly 2 and the sliding spacer 3 and be mounted to the strip conveyor table 1, preferably pivotably mounted to the strip conveyor table 1 about an axis W parallel to the conveying direction A of the strip 4. The support structure 11 can be arranged in a construction, for example in a section of the strip conveyor table 1, so that the section pivots about the pivot axis W relative to the base of the strip conveyor table 1. The pivot axis W can be designed as a pivot joint that pivotally connects the section of the strip conveyor table 1 (including at least the support structure 11 with the cutting assembly 2 and the sliding spacer 3 and the stroke drive 6) and the base of the strip conveyor table 1. Pivoting the cutting assembly 2 and the sliding spacer 3 about the pivot axis W is beneficial for applying the textile strip 4 because the cutting assembly and the sliding spacer 3 are lifted from the conveying plane of the strip conveyor table 1. Furthermore, when the cutting assembly 2 and the sliding spacer 3 are in an upright position, operations at the cutting assembly 2 or the sliding spacer 3 (such as maintenance or repair) are easier to perform.

[0091] Figure 6 The cutting assembly 2 and the sliding spacer 3 according to a further embodiment of the present invention are shown in FIG. Figure 5 Excerpt of details on the construction of a section of the strip conveyor table 1.

[0092] The construction may include a stroke drive 6, a tool connection assembly 10, two support structures 11 each having a cutting assembly 2 and a sliding spacer 3, a connecting rod 14, a first guide rail 16, a second guide rail 15, and a sliding body 17. The first guide rail 16 and the tool connection assembly 10, in particular the divided spindle, are arranged parallel to each other and connected to a plate pivotally mounted to the base of the strip conveyor table 1 around the axis W. The sliding body 17 is connected to the tool connection assembly 10 and guided in the first guide rail 16. On the sliding value, a second guide rail 15 is provided and arranged perpendicular to the tool connection assembly 10 and the first guide rail 16. The support structure 11 is guided by the second guide rail 15. The two support structures 11 are slidably connected via a connecting rod 14, which is parallel to the tool connection assembly 10 and the first guide rail 16. The connecting rod 14 is configured to allow the two support members 11 to slide along the first guide rail 16, wherein the two support structures 11 are driven by the tool connection assembly 10. Independently of the movement along the first guide rail 16, the travel drive 6 drives the support structure 11 along the second guide rail 15, wherein the travel drive 6 can be further fixed to the housing of the plate or segment of the strip conveyor table. The first guide rail 16 and the second guide rail 15 can be configured as a carriage guide system made of metal, light metal, plastic or a combination thereof.

[0093] Figure 7 and Figure 8 Shown is a schematic illustration of a support structure 11 with a cutting assembly 2 and a sliding spacer 3 according to a further embodiment of the invention.

[0094] The sliding spacer 3 may have a distal portion 30 which contacts the fabric when conveying the textile strip 4. The edges of the sliding spacer 3, in particular the distal portion 30, may provide a radius of less than 1 mm.

[0095] The sliding spacer 3 can further include an elongated body 31 extending from the distal portion 30 in a direction substantially perpendicular to the conveying direction A of the strip 4. Thus, the elongated body 31 includes an upper surface 32 that faces away from the fabric and extends from the fabric at an angle of between 10° and 80°, preferably between 35° and 55°, relative to the conveying plane of the strip conveyor table 1. The distal portion 30 and the elongated body 31 can be made of metal, light metal, plastic, or a combination thereof. Alternatively, the distal portion 30 and the elongated body 31 can be resiliently configured.

[0096] The cutting assembly 2 can be configured as a pair of scissors having a fixed scissor blade 20 and a movable scissor blade 21, wherein the movable scissor blade 21 is connected to an actuator 22, in particular a pneumatic cylinder, a hydraulic cylinder or an electromechanical cylinder. The actuator 22 is supported by the support structure 11. When transported in the strip conveyor table 1, the scissor blades 20, 21 can be arranged 0.2-0.5 mm above the textile strip 4. In addition, the scissor blades 20, 21 can be arranged parallel to the textile strip 4. Optionally, the scissor blades 20, 21 can be arranged at a certain angle, in particular 0° to 45°, around the longitudinal axis of the scissors relative to the textile strip 4, so that the cutting assembly 2 can more easily cut the raised metallized wire or filament 5 when the raised metallized wire or filament 5 extends essentially diagonally relative to the conveying plane of the strip conveyor table 1.

[0097] Preferably, the fixed scissors blade 20 is located below the movable scissors blade 21, but is not limited to the configuration and may also be located above the movable scissors blade 21. Figure 7 As can be seen in FIG, in the open position of the scissors, the movable scissors blade 21 can be closer to the sliding spacer 3 than the fixed scissors blade 20. Alternatively, in the open position of the scissors, the fixed scissors blade 20 can be closer to the sliding spacer 3 than the movable scissors blade 21. Each support structure 11 in the cutting device 100 that supports at least the cutting assembly 2, the sliding spacer 3 and the actuator 22 can have a separate configuration and does not necessarily have to be the same as the other support structures 11. Figure 4 and Figure 6 In some embodiments, one of the two support structures 11 supporting at least the cutting assembly 2 , the sliding spacer 3 and the actuator 22 is in an inverted configuration compared to the other of the two support structures 11 .

[0098] Specifically, Figure 7 The cutting assembly 2 and the sliding spacer 3 are shown in a second position ready to perform a cutting action to sever the metallized threads or filaments 5 from the fabric of the strip 4. The metallized threads or filaments 5 in the non-woven section 52 contact the upper surface 32 of the sliding spacer 3, which is positioned between the metallized threads or filaments 5 and the fabric of the strip 4. Figure 7 As shown, in the second position, the metallized lines or filaments 5 are lifted relative to the strip 4 by the gradient angle of the elongated body 31 of the sliding spacer 3 .

[0099] Further, Figure 8 Shown Figure 7 Schematic side view of the support structure 11.

[0100] The sliding spacer 3 may further include a solenoid 33 and may be magnetically connected via the solenoid 33 to an extension arm 34 that is pivotally fixed to the support structure 11 and has a corresponding counterpart to the solenoid 33 of the sliding spacer 3. In addition, a spring 35 is positioned at the proximal end of the extension arm 34 and supported in the support structure 11, wherein the spring 35 is configured to preload the sliding spacer 3 when the distal portion 30 is in contact with the fabric of the strip 4.

[0101] In order to adjust the distance of the cutting assembly 2 above the textile strip 4, the cutting assembly 2 and / or the sliding spacer 3 can be pivoted about the axis of a screw 36 in the support structure 11, the axis of the screw 36 being parallel to the conveying direction A of the strip 4. The screw 36 thus serves to loosen and re-secure it in the support structure 11.

[0102] Figure 9 A flow chart of a method M for severing a non-woven section 52 of threads or filaments 5 woven into a textile strip 4 according to a further embodiment of the invention is shown.

[0103] The method M comprises a step M1 of providing a cutting device 100 , in particular a cutting device 100 according to the first aspect of the invention, and a textile strip 4 having metallized threads or filaments 5 woven / non-woven quasi-annularly in the fabric of the strip 4 .

[0104] Furthermore, the method M comprises a transport step M2 of transporting the textile strip 4 in the strip transport station 1 along a transport direction A. During the transport step M2, the cutting assembly 2 and the sliding spacer 3 can be in a first position in which the distal end portion 30 of the sliding spacer 3 contacts the fabric. As a result, the distal end portion 30 can slide in the woven section 51 over the fabric of the textile strip 4 and the metallized threads or filaments 5 woven into the fabric of the textile strip without damaging the metallized threads or filaments 5 or the textile strip 4. In the event of a force being exerted on the sliding spacer 3, in particular on the distal end portion 30 or the elongated body 31, which force is above a defined threshold of the holding force of the solenoid 33, the sliding spacer 3 will be disconnected from the extension arm 34 at the solenoid 33.

[0105] Method M further includes a stopping step M3 of stopping the strip 4 after conveying the calculated travel distance. The calculated travel distance can be based on a reference position of the metallized thread or filament 5 in the fabric sensed by the sensor 7 and a predetermined length L of the woven / non-woven sections 51, 52 of the metallized thread or filament 5 in the fabric. The sensor 7 is particularly configured as a capacitive sensor, an inductive sensor, a magnetic field sensor, or an optical sensor. The sensor 7 can sense the reference position by being triggered to a characteristic point of the metallized thread or filament 5 passing through the sensor 7, such as the edge 50 of the non-woven section 52 or a specific inductive marker point of the strip 4 (for example, marked by a specific metallized member woven into the fabric of the strip 4 in addition to the metallized thread or filament 5 that triggers the sensor 7).

[0106] Furthermore, the method M comprises a moving step M4 of moving the cutting assembly 2 and the sliding spacer 3 from the first position to the second position, wherein the sliding spacer 3 slides between the metallized thread or filament 5 and the fabric of the strip 4 at the edge 50 of the non-woven section 52, thereby lifting the metallized thread or filament 5 from the fabric. In the moving step M4, the sliding spacer 3, with its distal end 30 in contact with the fabric, can slide substantially linearly transversely to the conveying direction A of the stopped strip 4, wherein the non-woven section 52 of the metallized thread or filament 5 can be lifted along the upper surface 32 of the sliding spacer 3, wherein the upper surface 32 faces away from the fabric and extends from the fabric at an angle of between 10° and 80°, preferably between 35° and 55°, relative to the conveying plane of the strip conveyor table 1.

[0107] Furthermore, method M includes simultaneously performing step M5 of simultaneously performing a cutting action for severing the non-woven section 52 of the metallized thread or filament 5 from the fabric of the strip 4 at the edge 50 of the non-woven section 52. The cutting action can be initiated by a control unit that can be electronically coupled to at least some components of the cutting device 100, particularly the stroke drive 6, the sensor 7, the strip transport drive, and the actuator 22. The cutting action can be performed in the second position of the cutting assembly 2 and the sliding spacer 3. For example, the actuator 22 simultaneously moves the movable scissor blade 21 while the metallized thread or filament 5 is lifted by the sliding spacer 3, and the portion of the metallized thread or filament extending between the sliding spacer 3 and the edge 50 is positioned within the fixed scissor blade 20 and the movable scissor blade 21, thereby cutting the metallized thread or filament 5 at the edge 50 of the non-woven section 52.

[0108] The method M may further comprise an adjustment step M6 of adjusting the distance between the cutting assemblies 2 along an axis parallel to the conveying direction A of the strip 4 via a tool connection assembly 10, in particular a spindle or an axis, to the length of the non-woven section 52 of the metallized thread or filament 5 in the fabric. Additionally or alternatively, the adjustment step M6 may further comprise adjusting M6 the distance between the sliding spacers 3 along an axis parallel to the conveying direction A of the strip 4 via a tool connection assembly 10, in particular a spindle or an axis, to the length of the non-woven section 52 of the metallized thread or filament 5 in the fabric.

[0109] Further, optionally or additionally, the adjustment step M6 may include: adjusting M6 the position of the cutting assembly 2 to the position of the edge 50 of the non-woven section 52 of the metallized line or filament 5 in the fabric via the tool connection assembly 10, in particular the spindle or shaft, along an axis parallel to the conveying direction A of the strip 4.

[0110] Optionally, the method M may further comprise a removal step M7 of removing the cut metallized wires or filaments 5 from the strip conveyor 1, wherein the removal action is performed by an air flow generated by the air flow generator 12 and flowing through the strip conveyor 1. The air flow may be generated continuously or again and again, in particular each time after the removal action has been performed.
