Description

Technical Field

[0001] This application relates to the field of fabric cutting technology, and in particular to a sunshade fabric cutting machine. Background Technology

[0002] Shading fabric cutting is an indispensable and crucial step in the production process of sunshades. Precise cutting ensures a perfect fit between the fabric and the sunshade, avoiding problems such as wrinkles and incomplete shading caused by fabric that is too large, or insufficient shading due to fabric that is too small. This ensures the proper functioning of the shading system. Ordinary cutting equipment cannot meet the cutting needs of various fabrics, affecting the overall performance and lifespan of the sunshade. Therefore, developing a shading fabric cutting machine has become a pressing technical challenge for the industry.

[0003] The existing technology still has the following problems: 1. Existing cutting machines are prone to problems such as fabric deviation and insufficient tension during the fabric output process. Fabric deviation can lead to skewed feeding, cutting size deviation, and uneven edges, resulting in material waste and affecting subsequent processing and the assembly effect of the sunshade. If the fabric lacks effective stress, it is prone to loosening, wrinkling, and stacking, resulting in rough edges, gaps, and inconsistent sizes during cutting, reducing the yield rate. Excessive stress can cause the fabric to be overstretched, leading to continuous cutting misalignment, increasing waste and rework costs.

[0004] 2. Problems such as insufficient positioning accuracy of the cutting distance of the cutting machine and easy deviation of the clamping and cutting mechanisms. Inaccurate cutting positioning will directly lead to the length not matching the design size, causing batch quality defects; continuous cutting error accumulation will cause material layout disorder, increase scrap rate, and increase production costs; long-term use of the clamping and cutting mechanisms will cause deviations that cannot be detected in time, which will lead to skewed feeding, uneven force, and asymmetrical clamping, further increasing scrap rate and rework costs, and seriously restricting production efficiency and pass rate. Summary of the Invention

[0005] To overcome the problems of fabric offset and insufficient tension that often occur during the fabric output process in cutting machines, this invention aims to provide a sunshade fabric cutting machine to address these shortcomings. Fabric offset can lead to skewed feeding, cutting size deviation, and uneven edges, resulting in material waste and affecting subsequent processing and awning assembly. Insufficient fabric stress can cause loosening, wrinkling, and stacking, leading to rough edges, gaps, and inconsistent dimensions during cutting, reducing yield. Insufficient cutting distance positioning accuracy and the tendency for clamping and cutting mechanisms to offset can also cause problems. Inaccurate cutting positioning directly results in length discrepancies with design dimensions, causing batch quality defects. Accumulated continuous cutting errors can cause disordered material output, increased scrap rate, and higher production costs. Long-term use of the clamping and cutting mechanisms can lead to undetected offsets, resulting in skewed feeding, uneven force, and asymmetrical clamping, further increasing scrap rate and rework costs, severely restricting production efficiency and yield.

[0016] The technical solution provided in this application has at least the following technical effects or advantages: 1. By employing a correction component, this invention effectively solves the problems of fabric misalignment and insufficient tension that often occur during the fabric output process in traditional cutting machines. Fabric misalignment can lead to skewed feeding, cutting size deviations, and uneven edges, resulting in material waste and affecting subsequent processing and awning assembly. Insufficient fabric stress can cause loosening, wrinkling, and stacking, leading to rough edges, gaps, and inconsistent dimensions, reducing yield. Excessive stress, on the other hand, can cause overstretching of the fabric, resulting in continuous cutting misalignment, increasing waste and rework costs. This invention uses a correction component to correct the fabric position in real time during output, preventing misalignment that causes size deviations and edge defects, ensuring accurate cutting lengths, saving raw materials, and simultaneously stabilizing the output tension to keep the fabric flat and taut, ensuring neat cuts and improving yield. An automatic alarm can be triggered when excessive tension occurs in the fabric roll, facilitating timely stress adjustment and ensuring continuous and stable output.

[0017] 2. By employing a positioning conveyor assembly, this invention effectively solves the problems of insufficient cutting distance positioning accuracy and easy misalignment between the clamping and cutting mechanisms in traditional cutting machines. Inaccurate cutting positioning directly leads to discrepancies between the length and the design dimensions, causing batch quality defects. Continuous accumulation of cutting errors causes disordered material feeding, increased scrap rate, and higher production costs. Long-term misalignment between the clamping and cutting mechanisms, which goes undetected, can lead to skewed feeding, uneven force, and asymmetrical clamping, further increasing scrap rate and rework costs, severely restricting production efficiency and pass rate. This invention, through its positioning conveyor assembly, can achieve precise cutting distance positioning as needed, ensuring that the fabric size meets production requirements. At the same time, it monitors the conveyor mechanism in real time to avoid misalignment during conveying, keeping the fabric flat and aligned, thereby significantly improving cutting accuracy, product pass rate, and production efficiency.

[0020] For issues such as misalignment and insufficient tension, this invention uses a correction component to correct the fabric position in real time during material output, preventing misalignment from causing dimensional deviations and edge defects, ensuring accurate cutting length, and saving raw materials. For insufficient positioning accuracy of cutting distance, this invention uses a positioning conveyor component to achieve precise positioning of cutting distance as needed, ensuring that the fabric size meets production requirements.

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods. Example

[0022] Please see Figure 1As shown, a sunshade fabric cutting machine includes a cutting machine body 1, a support table 2, a cutting mechanism 3, and a robotic arm 4. The support table 2 is fixedly installed on the outer surface of the cutting machine body 1. The cutting mechanism 3 is provided on the outer surface of the cutting machine body 1. The cutting mechanism 3 includes a second motor, a cutting blade, and a moving block. A third threaded rod is rotatably connected to the inner cavity of the cutting machine body 1. The moving block and the third threaded rod are connected by threads. The moving block and the cutting machine body 1 are slidably connected. A drive motor is provided in the inner cavity of the cutting machine body 1 to drive the third threaded rod to rotate. The second motor is located on the outer surface of the moving block, and the output end of the second motor is sleeved with the cutting blade. The cutting blade and the moving block are rotatably connected. The robotic arm 4 is provided on the outer surface of the cutting machine body 1. A straightening component 5 is provided on the outer surface of the cutting machine body 1. A fabric roll 6 is provided in the inner cavity of the straightening component 5. The outer surface of the main body 1 is equipped with a positioning conveying component 7, and the outer surface of the main body 1 of the cutting machine is equipped with a first motor 8. The fabric in the fabric roll 6 is passed through the straightening component 5. In this way, the position of the fabric is corrected by the straightening component 5 during the output, so as to ensure that the fabric output is neat. The operation of the first motor 8 drives the positioning conveying component 7 to move on the main body 1 of the cutting machine to the support table 2. At this time, the manipulator 4 places the fabric on the positioning conveying component 7 for clamping and fixing. The drive motor drives the third threaded rod to rotate, so that the moving block moves on the main body 1 of the cutting machine. In conjunction with the operation of the second motor, the cutting blade cuts the fabric. The positioning conveying component 7 can cut the fabric at a fixed distance. At the same time, it can ensure that the positioning conveying component 7 and the support table 2 always remain flush. This can evenly clamp and feed the fabric, thereby ensuring the integrity of the fabric cut.

[0023] Please see Figure 3 and Figure 4As shown, the corrective assembly 5 includes a connecting seat 51, with a retaining ring 52 slidably connected to the inner cavity of the connecting seat 51. The fabric roll 6 is rotatably connected to the retaining ring 52. A first connecting block 53 is fixedly installed on the outer surface of the connecting seat 51, and a stress rod 54 is rotatably connected to the outer surface of the first connecting block 53. The stress rod 54 is located directly above the support platform 2, and its bottom end is in contact with the support platform 2, allowing the fabric roll 6 to pass through the support platform 2 and the stress rod 54. An insertion hole 55 is provided on the outer surface of the connecting seat 51, and a corrective mechanism 56 is slidably connected to the outer surface of the connecting seat 51. The connecting seat 51 is fixedly connected to the outer surface of the cutting machine body 1. A limiting rod 57 is slidably connected to the outer surface of the connecting seat 51, and a limiting groove is provided on the upper surface of the retaining ring 52. One of the retaining rings 52 has two limiting grooves, and the limiting rod... 57 passes through the limiting groove of the connecting seat 51 and the retaining ring 52 and is inserted. The retaining ring 52 is limited by the limiting rod 57. When it is necessary to take out the fabric roll 6, the limiting rod 57 is disengaged from the limiting groove on the retaining ring 52, so that the retaining ring 52 moves into the inner cavity of the connecting seat 51. This allows the fabric roll 6 to fall out of the inner cavity of the retaining ring 52, making it easy to replace the fabric roll 6. The stress rod 54 on the first connecting block 53 is used to flatten the fabric. The straightening mechanism 56 is used to provide stress to the fabric and can correct the position of the fabric roll 6 to ensure uniform fabric output. At the same time, the position of the straightening mechanism 56 can be adjusted through the insertion hole 55. When the fabric wound on the fabric roll 6 changes, the position of the straightening mechanism 56 in the connecting seat 51 is adjusted to prevent insufficient or excessive stress when the fabric is output.

[0024] Please see Figure 4 , Figure 5 and Figure 6As shown, the correction mechanism 56 includes a correction frame 561. First insert rods 562 are threadedly connected to both ends of the correction frame 561. A buffer frame 563 is slidably connected to the outer surface of the correction frame 561. First slide rods 564 are fixedly installed at both ends of the buffer frame 563. A first spring 565 is sleeved on the outer surface of the first slide rods 564. A first threaded rod 566 is rotatably connected to the inner wall of the buffer frame 563. Adjustment blocks 567 are slidably connected to the inner cavities on both sides of the buffer frame 563. A buffer mechanism 568 is provided at one end of each adjustment block 567. The outer surfaces of the correction frame 561 and the connecting seat 51 are slidably connected. The first insert rods 562 are inserted into the insertion holes 55. The first slide rods 564 and the correction frame 561 are slidably connected. The first spring 565 is located between the buffer frame 563 and the correction frame. Between the inner walls of 561, the adjusting block 567 and the first threaded rod 566 are connected by threads, and the threads at both ends of the first threaded rod 566 are in opposite directions. The adjusting blocks 567 are symmetrically distributed about the middle part of the straightening frame 561. The buffer mechanism 568 includes a buffer rod 5681, a second connecting block 5682 is fixedly connected to the middle part of the buffer rod 5681, and second springs 5683 are sleeved at both ends of the buffer rod 5681. A straightening block 5684 is fixedly installed at the bottom end of the buffer rod 5681. Rotating rods 5685 are rotatably connected to the upper and lower inner walls of the straightening block 5684. A first fixing block 5686 is fixedly installed on the outer surface of the adjusting block 567, and an alarm block 5687 is fixedly installed on the inner wall of the first fixing block 5686. A spring rod 5688 is slidably connected to the cavity. One end of the spring rod 5688 is movably connected to a ball 5689. A first button 56810 is provided on the outer surface of the alarm block 5687. A compression block 56811 is fixedly installed on the outer surface of the spring rod 5688. The compression block 56811 and the alarm block 5687 are slidably connected. A third spring 56812 is sleeved on the end of the spring rod 5688 away from the ball 5689. A buffer rod 5681 and an adjusting block 567 are slidably connected. Each buffer rod 5681 has two second springs 5683, one located between the buffer rod 5681 and the adjusting block 567, and the other located between the adjusting block 567 and the corrective block 5684. The ball 5689 and the second connecting block 5682 are in close contact. The first button... Button 56810 and extrusion block 56811 are electrically connected, and pressing the first button 56810 controls the first alarm 56813 to sound an alarm. The third spring 56812 is located between the inner walls of extrusion block 56811 and alarm block 5687. The junction between the second connecting block 5682 and buffer rod 5681 is chamfered. When the fabric is being discharged, the spacing of the buffer mechanism 568 is adjusted according to the width of the fabric. By rotating the first threaded rod 566, the adjusting block 567 slides on the buffer frame 563, so that the fabric can pass between the two buffer mechanisms 568, that is, the fabric in the fabric roll 6 passes between the rotating rod 5685 in the inner cavity of the straightening block 5684. When the fabric deviates horizontally, it will squeeze the buffer mechanism 568.At this time, the buffer mechanism 568 drives the adjusting block 567 to move. The movement of the adjusting block 567 causes the buffer frame 563 to move on the outer surface of the straightening frame 561. The movement of the buffer frame 563 causes the first slide rod 564 to slide in the inner cavity of the straightening frame 561 and compress the first spring 565. The elastic force of the first spring 565 is used to make the buffer frame 563 quickly return to its original position, so that when the fabric is horizontally offset, it can be quickly corrected, thereby ensuring the stability of the fabric during output, preventing the offset from causing dimensional deviation and edge defects, ensuring accurate cutting length, saving raw materials, and so on. The tension of the material is stably controlled to keep the fabric flat and taut, ensuring clean cuts and improving the yield rate. The first insert 562 engages with insert holes 55 at different positions to provide stress when the fabric passes the rotating rod 5685. When the fabric moves up and down, the straightening block 5684 drives the buffer rod 5681 to slide within the adjusting block 567 and compress the second spring 5683. The elasticity of the second spring 5683 allows the fabric to quickly return to its original position, thus stabilizing the fabric. When adjusting the position of the straightening mechanism 56, the fabric passes the rotating rod 5685... Maintaining a certain stress at 85°C prevents fabric from piling up and wrinkling during cutting. When the fabric on the outer surface of fabric roll 6 is reduced, the pressure on the straightening block 5684 changes, causing the position of the buffer rod 5681 on the adjusting block 567 to change. When the change is significant, the second connecting block 5682 detaches and contacts the ball 5689, causing the ball 5689 to be squeezed at the junction of the buffer rod 5681 and the second connecting block 5682. At this time, the elastic rod 5688 slides in the inner cavity of the alarm block 5687, causing the squeezing block 56811 to be squeezed at the alarm block 5687. The sliding motion within the 687 cavity compresses the first button 56810, triggering the first alarm 56813. This alerts the operator that excessive stress is present, requiring adjustment of the position of the straightening mechanism 56 on the connecting seat 51. Specifically, as the fabric decreases during cutting, the straightening mechanism 56 adjusts its position based on the alarm from the first alarm 56813. This allows the straightening mechanism 56 to provide appropriate stress to the fabric while also offering cushioning when stress is high. The alarm prevents fabric breakage and ensures continuous and stable material output. Example

The surfaces are fixedly connected, and the first cylinder 771 and the moving frame 71 do not contact each other. When the positioning and conveying assembly 7 conveys and cuts the fabric at a fixed distance, the operation of the first motor 8 drives the second threaded rod to rotate, causing the moving frame 71 to move on the outer surface of the cutting machine body 1. The moving frame 71 moves to the support platform 2, and the operation of the robot arm 4 places the fabric on the connecting frame 73. The operation of the first cylinder 771 drives the first piston rod 772 to slide in the inner cavity of the first cylinder 771. At this time, the drive rod on the drive block 773 slides in the inner cavity of the drive groove 775, causing the clamping plate 774 to slide in the inner cavity of the connecting frame 73, so that the fabric is clamped and fixed between the clamping plate 774 and the connecting frame 73. The first motor 8 drives the moving frame 71 to move. When it reaches the designated position, the second cylinder 78 drives the second piston rod 79 to lift the positioning wheel 710, so that the positioning wheel 710 squeezes the positioning mechanism 72 to position the positioning mechanism 72, thereby positioning the connecting frame 73 and ensuring the accuracy of the cutting spacing. This ensures that the cutting spacing meets the requirements each time. The horizontal detection mechanism 74 is used to detect whether the connecting frame 73 and the support platform 2 are always flush, thereby preventing the fabric from remaining neat when stretched. The anti-offset mechanism 76 on the second fixed block 75 is used to detect whether there is any offset between the connecting frame 73 and the support platform 2, thereby further improving the cutting accuracy of the fabric.

[0026] Please see Figure 7 , Figure 9 and Figure 11As shown, the positioning mechanism 72 includes a positioning block 721. Second slide rods 722 are fixedly installed at both ends of the positioning block 721. A fourth spring 723 is sleeved on the outer surface of the second slide rod 722. A positioning groove 724 is formed at the bottom end of the fourth spring 723. The second slide rod 722 is slidably connected to the inner cavity of the moving frame 71. The fourth spring 723 is located between the inner wall of the moving frame 71 and the positioning block 721. The positioning groove 724 is formed at the bottom end of the positioning block 721, and the two sides of the positioning groove 724 are chamfered. The operation of the second cylinder 78 drives the top of the positioning wheel 710 to engage with the positioning groove 724. The lower surface of the positioning block 721 is fixedly connected to the upper surface of the connecting frame 73. When positioning the fabric, the position of the second cylinder 78 on the main body 1 of the cutting machine is first adjusted. At this time, the moving frame 71 moves... After the set distance is reached, the second cylinder 78 drives the positioning wheel 710 to press the positioning groove 724, making the positioning groove 724 and the positioning wheel 710 fit tightly. When the position of the moving frame 71 deviates, the positioning wheel 710 will press the chamfer of the positioning groove 724, thereby causing the positioning block 721 to change its position in the inner cavity of the moving frame 71. At the same time, it causes the second slide rod 722 to slide in the inner cavity of the moving frame 71 and press the fourth spring 723. The change in the position of the positioning block 721 causes the position of the connecting frame 73 to change relative to the moving frame 71. This allows for secondary positioning when the position of the moving frame 71 is not accurate enough, so that the fabric cutting distance can meet the design requirements, which facilitates subsequent reprocessing and avoids material waste.

[0027] Please see Figure 12 , Figure 13 , Figure 14 and Figure 15As shown, the horizontal detection mechanism 74 includes a detection block 741. A slide block 742 is slidably connected to the inner cavity of the detection block 741. A fifth spring 743 is sleeved on one end of the slide block 742. The fifth spring 743 is located between the slide block 742 and the inner wall of the detection block 741. An elastic ring 744 is rotatably connected to the inner cavity of the slide block 742. A balance block 745 is rotatably connected to the inner cavity of the detection block 741. A balance plate 746 is fixedly installed on the outer surface of the balance block 745. Contact blocks 747 are rotatably connected to both ends of the balance plate 746. Second buttons 748 are provided at both ends of the balance plate 746. A second alarm 749 is fixedly installed on the outer surface of the balance plate 746. The detection block 741 and the connecting frame 73 are fixedly connected. The balance blocks 745 are symmetrically distributed about the elastic ring 744. The second button 748 is attached to the second fixing block 75, and the second button 748 is electrically connected to the second alarm 749. Pressing the second button 748 controls the second alarm 749 to sound an alarm. The anti-deviation mechanism 76 includes a fixing ring 761, a groove 762 on the outer surface of the fixing ring 761, a positioning rod 763 in the middle of the fixing ring 761, a third slide rod 764 fixedly mounted on the outer surface of the positioning rod 763, a sixth spring 765 sleeved on the outer surface of the third slide rod 764, and a washer 766 slidably connected to the outer surface of the third slide rod 764. The third button 767 is provided on the outer surface of the second fixing block 75, and the third alarm 768 is fixedly mounted on the outer surface of the second fixing block 75. The outer surface of the support platform 2 is fixedly mounted with... The second insert rod 769, the third slide rod 764, and the slide groove 762 are slidably connected. The sixth spring 765 is located between the positioning rod 763 and the washer 766. The washer 766 is slidably connected to the inner wall of the fixing ring 761. The outer surfaces of the fixing ring 761 and the second fixing block 75 are fixedly connected. Both ends of the positioning rod 763 are chamfered. The end of the third button 767 near the positioning rod 763 is chamfered. The inner wall of one end of the third button 767 is in contact with the positioning rod 763. The third button 767 is electrically connected to the third alarm 768, and pressing the third button 767 controls the third alarm 768 to sound an alarm. The axes of the positioning rod 763 and the second insert rod 769 are aligned. When the moving frame 71 moves, it causes the contact block 747 to make tight contact with the outer surface of the support platform 2. The second insertion rod 769 and the positioning rod 763 are engaged, and the second insertion rod 769 and the third button 767 are not in contact. During the process of the connecting frame 73 moving to the support platform 2 to clamp the fabric, the contact block 747 contacts the outer surface of the support platform 2 to detect whether the connecting frame 73 and the support platform 2 are flush. When the connecting frame 73 tilts, it causes the balance plate 746 to tilt. At this time, one end of the contact block 747 first contacts the outer surface of the support platform 2 and generates pressure, so that the balance plate 746 presses against the detection block 741. At this time, the balance block 745 rotates in the inner cavity of the detection block 741 and presses against the elastic ring 744. The pressing of the elastic ring 744 causes the slide 742 to slide in the inner cavity of the detection block 741 and press against the fifth spring 743.At this time, during the contact process between the contact block 747 and the support platform 2, the balance plate 746 is restored to horizontal, thereby causing the second button 748 and the second fixing block 75 to contact and generate pressure, causing the second alarm 749 to sound an alarm, reminding the staff that the relative tilt between the connecting frame 73 and the support platform 2 affects the flatness of the fabric output, requiring equipment maintenance. In addition, when the connecting frame 73 moves to the support platform 2, the second insert rod 769 and the positioning rod 763 are engaged. When the position of the connecting frame 73 shifts, the second insert rod 769 will press against the chamfer of the positioning rod 763. At this time, the positioning rod 763 shifts in the inner cavity of the fixing ring 761, causing the third slide rod 764 to slide in the inner cavity of the slide groove 762 and generate pressure on the sixth spring 765. The compression causes the pad 766 to slide within the cavity of the fixing ring 761, while the positioning rod 763 presses the third button 767, triggering the third alarm 768 to sound. This alerts the operator that the connecting frame 73 has shifted relative to the support platform 2, requiring timely maintenance. The alarm sounds of the third alarm 768, the second alarm 749, and the first alarm 56813 are different, facilitating problem differentiation and rapid maintenance. This allows for precise positioning of the fabric cutting distance as needed, ensuring the fabric size meets production requirements. Simultaneously, real-time monitoring of the connecting frame 73 prevents shifting or tilting during fabric transport, keeping the fabric flat and aligned, thus significantly improving cutting accuracy, product qualification rate, and production efficiency.

[0028] In summary, the fabric in fabric roll 6 is passed through the straightening component 5. During discharge, the straightening component 5 corrects the position of the fabric, ensuring neat discharge. The first motor 8 drives the positioning conveying component 7 to move on the cutting machine body 1 to the support table 2. At this point, the robotic arm 4 places the fabric on the positioning conveying component 7 for clamping and fixing. The drive motor rotates the third threaded rod, causing the moving block to move on the cutting machine body 1. The second motor, in conjunction with the second motor, drives the cutting blade to cut the fabric. The positioning conveying component 7 allows for precise, distance-based cutting of the fabric, while simultaneously ensuring the alignment of the positioning conveying component 7 and the support table. The two platforms remain flush to ensure even fabric clamping and feeding, guaranteeing the integrity of the fabric cut. A limiting rod 57 limits the position of the retaining ring 52. When the fabric roll 6 needs to be removed, the limiting rod 57 disengages from the retaining ring 52 and engages with the limiting groove on the retaining ring 52, causing the retaining ring 52 to move into the inner cavity of the connecting seat 51. This allows the fabric roll 6 to fall out of the retaining ring 52, facilitating replacement. The stress rod 54 on the first connecting block 53 is used to flatten the fabric. The straightening mechanism 56 provides stress to the fabric and corrects the exit position of the fabric roll 6, ensuring even fabric output. Simultaneously, it can be inserted through the insertion hole... 55. Adjust the position of the straightening mechanism 56. When the fabric wound on the fabric roll 6 changes, adjust the position of the straightening mechanism 56 at the connecting seat 51 to prevent insufficient or excessive stress when the fabric is discharged. The positioning and conveying component 7 cuts the fabric at a fixed distance. The operation of the first motor 8 drives the second threaded rod to rotate, causing the moving frame 71 to move on the outer surface of the cutting machine body 1. The moving frame 71 moves to the support table 2. The operation of the robot arm 4 places the fabric on the connecting frame 73. The clamping mechanism 77 clamps and fixes the fabric on the connecting frame 73. The operation of the first motor 8 drives the moving frame 71 to move. When the designated position is reached, the operation of the second cylinder 78 drives the second piston rod 79 to lift the positioning wheel 710, so that the positioning wheel 710 squeezes the positioning mechanism 72 to position the positioning mechanism 72, thereby positioning the connecting frame 73 and ensuring the accuracy of the cutting spacing positioning, so that the spacing of each cut meets the requirements. The horizontal detection mechanism 74 is used to detect whether the connecting frame 73 and the support platform 2 are always kept flat, thereby preventing the fabric from remaining neat when stretched. The anti-offset mechanism 76 on the second fixing block 75 is used to detect whether there is an offset between the connecting frame 73 and the support platform 2, thereby further improving the cutting accuracy of the fabric.
