Description

Technical Field

[0001] This utility model relates to the field of material gripping, and in particular to a flexible material gripping device and an automatic glove blank loading mechanism. Background Technology

[0002] In traditional flexible material gripping mechanisms, needle-type suction cups are typically used for gripping. The bottom suction cup picks up the flexible material, and the needle tip at the top pierces into the flexible material to achieve gripping. However, in this method, the needle tip is prone to excessively piercing the plane, causing the needle tip to bend and be damaged, reducing the service life of the equipment. At the same time, the contact area between the needle-type suction cup and the flexible material is small, resulting in unreliable overall gripping and a low success rate.

[0003] Chinese patent CN107839934A discloses a tool for opening plastic bags in industrial production. It uses suction cups on two pressure plates to adhere to both sides of the plastic bag, thus opening the bag. However, the suction cups have a small gripping area, resulting in a weak gripping and a low success rate. Utility Model Content

[0035] 1. The solution of this utility model sets the bottom surface of the first clamping structure as a flat plane, and increases the contact area between the first clamping structure and the flexible material by increasing its gripping area, thereby improving gripping efficiency and stability.

[0036] 2. The present invention uses a first clamping structure to change the size of the first gap to grip the top side of the flexible material, and a second clamping structure to change the size of the second gap to grip the bottom side of the flexible material. This gripping method is more reliable than the traditional needle suction cup. Furthermore, by misaligning the first and second gaps, the plane of the first opening and closing component abuts against the second gap, and the plane of the second opening and closing component abuts against the first gap. This allows the flexible material to enter the first and second gaps to a certain extent, assisting the device in gripping and further improving the gripping success rate.

[0037] 3. With the solution of this utility model, the installation position of the fixing member and the first opening and closing component is adjustable, so that by changing the installation position of the fixing member, the size of the first gap on both sides can always be kept consistent, avoiding the situation where one side can grasp flexible materials while the other side fails to grasp them due to the gap being too large, thus improving the grasping stability.

[0038] 4. In the solution of this utility model, the first clamping member and the second clamping member are provided with a first anti-slip structure, and the third clamping member and the fourth clamping member are provided with a second anti-slip structure. The first anti-slip structure and the second anti-slip structure protrude from the surface, which can increase the friction between the clamping member and the flexible material and further improve the gripping success rate of the device.

[0039] 5. The present invention provides a first limiting structure on the side of the first opening and closing component and a second limiting structure on the side of the second opening and closing component. The first limiting structure and the second limiting structure can adjust the size of the first gap and the second gap, so that a larger gap is suitable for gripping a thicker glove blank and a smaller gap is suitable for gripping a thinner glove blank, thereby improving the overall applicability of the device.

[0050] Figure 1 This diagram illustrates the structure of a flexible material gripping device according to one embodiment of the present invention. Figure 2 This diagram schematically illustrates the structure of a first clamping structure according to one embodiment of the present invention. Figure 3 This schematic diagram illustrates the structure of the second clamping structure according to one embodiment of the present invention, as shown below. Figure 1-3 As shown, the flexible material gripping device of this utility model includes:

[0051] The first opening and closing component 10 has a first clamping structure 101 on the side facing the flexible material. The first clamping structure 101 includes a first clamping member 1012 and a second clamping member 1013 that are movably connected to the first opening and closing component 10. The first clamping member 1012 and the second clamping member 1013 are used to cooperate to grip or release the flexible material.

[0052] The area of ​​the orthographic projection of the bottom contact surface of the first clamping member 1012 and the second clamping member 1013 ranges from 0.5 cm2 to 20 cm2.

[0053] Specifically, the bottom contact surface of the first clamping member 1012 and the second clamping member 1013 is represented by the entire bottom surface of the first clamping member 1012 and the second clamping member 1013.

[0054] The first clamping structure 101 also includes a fastener 1014 and a first gap 1011;

[0055] The fixing member 1014 is connected to the first opening and closing assembly 10. The first clamping member 1012 and the second clamping member 1013 are movably connected to the first opening and closing assembly 10. The connection includes a sliding connection and a rotational connection. When the first clamping member 1012 and the second clamping member 1013 are slidably connected to the first opening and closing assembly 10, the first clamping member 1012 and the second clamping member 1013 can move laterally in the horizontal direction. When they are rotatably connected, the first clamping member 1012 and the second clamping member 1013 swing towards or away from the fixing member 1014 with one end as the axis.

[0056] A first gap 1011 is provided between the first clamping member 1012 and the fixing member 1014, and between the second clamping member 1013 and the fixing member 1014. The first opening and closing assembly 10 is used to control the movement of the first clamping member 1012 and the second clamping member 1013 to change the size of the first gap 1011 to grip or release flexible materials.

[0057] When gripping flexible materials, the first clamping member 1012 and the second clamping member 1013 are controlled to move towards the fixing member 1014, so that the first gap 1011 on both sides of the fixing member 1014 gradually decreases, thereby realizing the gripping operation of flexible materials.

[0058] Furthermore, the first opening and closing component 10 of this solution can cooperate with the opening and closing device of the gripper-type or needle-type suction cup in the transmission technology. The first opening and closing component 10 is located on the top of the gripper-type or needle-type suction cup, and the two correspond to each other. The first opening and closing component 10 grips one side of the flexible material, and the gripper-type or needle-type suction cup opening and closing device grips the other side of the flexible material. The opening operation of the flexible material is realized by moving one of the two away from the other or by moving away from each other at the same time.

[0059] Furthermore, the flexible material gripping device of this utility model also includes a second opening and closing component 20, which has a second clamping structure 201 on the side facing the flexible material. The second clamping structure 201 includes a third clamping member 2012 and a fourth clamping member 2013 that are movably connected to the second opening and closing component 20. The third clamping member 2012 and the fourth clamping member 2013 are used to cooperate to grip or release the flexible material.

[0060] The projected area of ​​the bottom contact surfaces of the third clamping member 2012 and the fourth clamping member 2013 is 0.5 cm². 2 -20cm 2 .

[0061] Specifically, similarly, the bottom contact surfaces of the third clamping member 2012 and the fourth clamping member 2013 are also represented as the entire bottom plane of the third clamping member 2012 and the fourth clamping member 2013.

[0062] The second clamping structure 201 also includes a second gap 2011;

[0063] The third clamping member 2012 and the fourth clamping member 2013 are movably connected to the second opening and closing assembly 20. Similarly, they can be implemented in two ways: sliding connection and rotational connection.

[0064] A second gap 2011 is provided between the third clamping member 2012 and the fourth clamping member 2013. The second opening and closing assembly 20 is used to control the movement of the third clamping member 2012 and the fourth clamping member 2013 to change the size of the second gap to grip or release flexible materials.

[0065] With this configuration, the first opening and closing component 10 grips one side of the flexible material, and the second opening and closing component 20 grips the other side of the flexible material. The two components are far apart from each other, which enables the opening operation of the flexible material to be automated.

[0066] Meanwhile, the bottom of the first opening and closing component 10 and the top of the second opening and closing component 20 are set as planes, which can increase the contact area with the flexible material, making the gripping of both sides of the flexible material stable and reliable. At the same time, compared with the structure of the traditional needle suction cup, it can effectively avoid the equipment from colliding and being damaged.

[0067] Furthermore, the first gap 1011 and the second gap 2011 are staggered, and the second gap 2011 corresponds to the fixing member 1014. This ensures that the bottom surfaces of the first gap 1011 on the first opening and closing assembly 10 correspond to the bottom surfaces of the third clamping member 2012 and the fourth clamping member 2013 on the second opening and closing assembly 20, and the bottom surface of the second gap 2011 on the second opening and closing assembly 20 corresponds to the bottom surface of the fixing member 1014 on the first opening and closing assembly 10. This achieves a correspondence between the gap of one component and the surface of the other. When the two components approach and press against each other, the flexible material corresponding to the first gap 1011 and the second gap 2011 can further enter the gaps, increasing the contact area between the first clamping structure 101 and the second clamping structure 201 and the two sides of the flexible material, thereby enhancing the gripping effect and making the opening device grip more securely. Furthermore, as... Figure 2 As shown, the fixing member 1014 is installed in an adjustable position on the first opening and closing assembly 10, and the fixing member 1014 is used to ensure the size of the first gap 1011 on both sides.

[0068] Specifically, in the first embodiment, a first mounting hole 10141 is provided on the fixing member 1014, and a second mounting hole 102 is provided on the first opening and closing assembly 10. The length of the first mounting hole 10141 along the moving direction of the first clamping structure 101 is greater than the length of the second mounting hole 102 along the moving direction of the first clamping structure 101. The first mounting hole 10141 and the second mounting hole 102 are used for inserting the mounting member so that the fixing member 1014 is fixedly connected to the first opening and closing assembly 10.

[0069] The mounting component is threaded into the second mounting hole 102. The mounting component can be a screw. By controlling the fixing component 1014 to move a certain distance to the left or right, different positions of the first mounting hole 10141 correspond to the second mounting hole 102. Then, by passing the screw through the first mounting hole 10141 and the second mounting hole 102 in sequence, the fixing component 1014 is fixedly connected to the first opening and closing component 10. By changing the installation position of the fixing component 1014 and the first opening and closing component 10, the size of the first gap 1011 between the fixing component 1014 and the first clamping component 1012 and the second clamping component 1013 is kept consistent. This ensures that when the first opening and closing component 10 grips the flexible material through the first gap 1011, the gripping effect of the flexible material is uniform, improving the gripping effect and the opening effect of the flexible material when it is subsequently engaged with the second opening and closing component 20.

[0070] Meanwhile, in the second embodiment, the fixing member 1014 can also be movably connected to the first opening and closing component 10 through other structures that can control the movement of the fixing member 1014, such as setting a slide rail or a slider to realize the left and right sliding of the fixing member 1014.

[0071] Furthermore, two fasteners 1014 can be provided, which are parallel to each other and arranged side by side. One fastener 1014 is located near the first clamping member 1012 and can adjust the size of the first gap 1011 on that side. The other fastener 1014 is located near the second clamping member 1013 and can adjust the size of the first gap 1011 on that side, thus achieving individual adjustment.

[0072] Furthermore, a first limiting structure 103 is provided on one or both sides of the first opening and closing component 10, and the first limiting structure 103 is used to adjust the size of the first gap 1011.

[0073] A second limiting structure 202 is provided on one or both sides of the second opening and closing component 20. The second limiting structure 202 is used to adjust the size of the second gap 2011.

[0074] Specifically, the first limiting structure 103 includes a first mounting bracket 1031, a second mounting bracket 1032 and a first limiting member 1033. One end of the first mounting bracket 1031 is fixedly connected to the second mounting bracket 1032, and the other end is fixedly connected to the first opening and closing assembly 10. The second mounting bracket 1032 is parallel to and spaced apart from the side of the first opening and closing assembly 10.

[0075] The first mounting bracket 1031 is horizontally arranged, and the second mounting bracket 1032 is perpendicular to the first mounting bracket 1031 to form an "L" shaped plate. In another embodiment, the first mounting bracket 1031 and the second mounting bracket 1032 can be detachably connected. Similarly, the first mounting bracket 1031 and the first opening and closing component 10 can also be detachably connected.

[0076] The first limiting member 1033 is movably mounted on the second mounting bracket 1032. The size of the first gap 1011 can be adjusted by controlling the forward and backward movement of the first limiting member 1033 to control its extension length from the second mounting bracket 1032.

[0077] The first limiting member 1033 can be configured as a screw, which is threadedly connected to the second mounting bracket 1032. The forward and backward movement is achieved by rotating the first limiting member 1033, so that when the first clamping member 1012 or the second clamping member 1013 moves away from each other by a certain distance, they will abut against the first limiting member 1033, thereby limiting the further movement of the two, thus limiting the opening size of the first gap 1011.

[0078] When the first opening and closing assembly 10 grasps the thinner glove blank, by controlling the first limiting member 1033 to move forward, the first clamping member 1012 or the second clamping member 1013 moves closer to the fixing member 1014, thereby reducing the size of the first gap 1011. At this time, the first opening and closing assembly 10 can grasp the thinner glove blank. During the process of reducing the size of the first gap 1011, if the size of the fixing member 1014 is too large, the fixing member 1014 needs to be removed from the first opening and closing assembly 10, and a smaller fixing member 1014 needs to be installed simultaneously. Then, the first gaps 1011 on both sides are adjusted to ensure that the size of the first gaps 1011 on both sides is consistent.

[0079] When gripping a thicker glove blank, by controlling the first limiting member 1033 to move backward, the first clamping member 1012 or the second clamping member 1013 moves away from the fixing member 1014, thereby increasing the size of the first gap 1011, accommodating more glove blank fabric, and realizing the gripping of a thicker glove blank.

[0080] Meanwhile, in another embodiment, the first limiting member 1033 can also be fixedly connected to the second mounting bracket 1032, so that the first gap 1011 has a fixed size, but this method can only realize the gripping operation of a single size glove blank.

[0081] Furthermore, the second limiting structure 202 includes a third mounting bracket 2021, a fourth mounting bracket 2022, and a second limiting member 2023. One end of the third mounting bracket 2021 is fixedly connected to the fourth mounting bracket 2022, and the other end is fixedly connected to the second opening and closing assembly 20. The fourth mounting bracket 2022 is parallel to and spaced apart from the side of the second opening and closing assembly 20.

[0082] The second limiting structure 202 is configured the same as the first limiting structure 103. It can also be adjusted to move forward or backward to accommodate the gripping of glove blanks of different thicknesses.

[0083] With this configuration, the first limiting structure 103 and the second limiting structure 202 enable the device to adapt to glove blanks of different thicknesses, effectively improving the applicability of the device.

[0084] Furthermore, a first anti-slip structure 1015 is provided on the bottom plane of the first clamping member 1012 and the second clamping member 1013, and the first anti-slip structure 1015 protrudes or is recessed on the surface.

[0085] A second anti-slip structure 2014 is provided on the top plane of the third clamping member 2012 and the fourth clamping member 2013. The second anti-slip structure protrudes or is recessed on the surface.

[0086] Specifically, a first anti-slip structure 1015 is provided in the middle and on both sides of the first clamping member 1012 and the second clamping member 1013, and the first anti-slip structure 1015 is arranged parallel or perpendicular to the moving direction of the first clamping member 1012 and the second clamping member 1013. The first anti-slip structure 1015 is set in a strip shape or a wave shape. When the first opening and closing component 10 presses down on the flexible material, the first anti-slip structure 1015 can further extend into the flexible material, increase the friction with the flexible material, and make the gripping effect of the flexible material more reliable.

[0087] Second anti-slip structures 2014 are respectively provided in the middle and on both sides of the third clamping member 2012 and the fourth clamping member 2013. The second anti-slip structures 2014 are also parallel or perpendicular to the movement direction of the second clamping structure 201. When the third clamping member 2012 and the fourth clamping member 2013 are close to each other, the two second anti-slip structures 2014 are correspondingly provided with the fixing member 1014. The second anti-slip structures 2014 can be set as long strips or waves.

[0088] When the second opening and closing component 20 comes into contact with the flexible material, the second anti-slip structure 2014 can extend further into the flexible material, increasing the friction with the flexible material and thus improving the gripping effect.

[0089] Meanwhile, the first anti-slip structure 1015 and the second anti-slip structure 2014 can also be implemented using other anti-slip methods, such as adding texture to the surface or using a coating, to increase the friction between the first opening and closing component 10, the second opening and closing component 20 and the flexible material, prevent the material from sliding or detaching, and thus improve the gripping effect.

[0090] Furthermore, Figure 4 This schematic diagram illustrates the structure of the third anti-slip structure according to one embodiment of the present invention, as shown below. Figure 3 , 4 As shown:

[0091] A third anti-slip structure 1016 is provided on the surfaces of the first clamping member 1012 and the second clamping member 1013 facing each other. The third anti-slip structure 1016 protrudes or is recessed in the surface. A fourth anti-slip structure 2015 is provided on the surfaces of the third clamping member 2012 and the fourth clamping member 2013 facing each other. The fourth anti-slip structure 2015 protrudes or is recessed in the surface.

[0092] Specifically, the third anti-slip structure 1016 and the fourth anti-slip structure 2015 can also be configured as a strip or a wave shape. When the flexible material enters between the first gap 1011 and the second gap 2011, the first clamping member 1012 and the second clamping member 1013 move towards the fixing member 1014 respectively to clamp one side of the flexible material. The third anti-slip structure 1016 provided on its clamping surface can further increase the friction between it and the flexible material, making it easier to grasp.

[0093] Similarly, when the third clamping member 2012 and the fourth clamping member 2013 move close to each other to clamp the other side of the flexible material, the fourth anti-slip structure 2015 provided on their clamping surfaces can also increase the friction with the flexible material, making it easier to grip.

[0094] Furthermore, a fifth anti-slip structure (not shown in the figure) can also be provided on the two surfaces of the fixing member 1014 facing the first clamping member 1012 and the second clamping member 1013. The fifth anti-slip structure is also set to be raised or recessed on the setting surface, which can further enhance the friction between the fixed member 1014 and the flexible material and improve the gripping effect.

[0095] It is understandable that the first anti-slip structure 1015, the second anti-slip structure 2014, the third anti-slip structure 1016, the fourth anti-slip structure 2015, and the fifth anti-slip structure can also be other shapes, as long as they can increase the friction force. No specific limitations are made here.

[0096] Furthermore, Figure 5 This schematic diagram illustrates the structure of a flexible material gripping device according to another embodiment of the present invention, as shown below. Figure 1 , 5 As shown:

[0097] In the present invention, the first opening and closing component 10 and the second opening and closing component 20 can be interchanged. The first opening and closing component 10 can be located above the second opening and closing component 20, so that the first opening and closing component 10 grasps the flexible material and moves towards the second opening and closing component 20. Alternatively, the second opening and closing component 20 can be located above the first opening and closing component 10, so that the second opening and closing component 20 grasps the flexible material and moves towards the first opening and closing component 10.

[0098] like Figure 1As shown, in the first embodiment, the first opening and closing component 10 is located above the second opening and closing component 20, and the second anti-slip structure 2014 protrudes from the setting surface. When the first opening and closing component 10 moves down and fits against the second opening and closing component 20, the second anti-slip structure 2014 protruding on the second opening and closing component 20 can contact the bottom surface of the fixing member 1014, thereby achieving the clamping of the flexible material, enabling the third clamping member 2012 and the fourth clamping member 2013 to grasp the flexible material.

[0099] like Figure 5 As shown, in the second embodiment, the second opening and closing component 20 is located above the first opening and closing component 10. Since the second anti-slip structure 2014 protrudes from the setting surface, when the second opening and closing component 20 moves down and fits against the first opening and closing component 10, the second anti-slip structure 2014 abuts against the fixing member 1014, which will cause the first clamping member 1012 and the second clamping member 1013 to be unable to abut against the bottom surfaces of the third clamping member 2012 and the fourth clamping member 2013, thus failing to clamp the flexible material. Consequently, when the first clamping member 1012 and the second clamping member 1013 move towards the fixing member 1014, the gripping effect on the flexible material is poor.

[0100] Therefore, in this method, a first groove 10142 is provided on the surface of the fastener 1014 that contacts the flexible material. The first groove 10142 is located at the center of the fastener 1014, and two second anti-slip structures 2014 are provided corresponding to the first groove 10142.

[0101] When the first opening and closing component 10 is in contact with the second opening and closing component 20, the second anti-slip structure 2014 extends into the first groove 10142 so that the first anti-slip structure 1015 abuts against the surfaces of the third clamping member 2012 and the fourth clamping member 2013.

[0102] With this configuration, the second anti-slip structure 2014 located at the top extends further into and sinks into the first groove 10142 at the bottom, so that the first anti-slip structure 1015 on the first clamping member 1012 and the second clamping member 1013 at the bottom can abut against the surfaces of the third clamping member 2012 and the fourth clamping member 2013 at the top, thereby achieving the clamping of flexible materials and ensuring that the first opening and closing component 10 can grasp flexible materials.

[0103] It is understandable that providing a first groove 10142 on the fixing member 1014 can also be applied to the first embodiment to further improve the gripping effect on flexible materials.

[0104] Furthermore, the top of the first opening and closing assembly 10 is provided with one or more optical axes 30, and an elastic element 40 is sleeved on the outside of the optical axis 30. The optical axis 30 is used to control the vertical movement of the first opening and closing assembly 10.

[0105] Specifically, the elastic element 40 is elastic. When the optical axis 30 is set to one, and it controls the first opening and closing component 10 to move downward, the elastic element 40 can adjust the pressure applied by the first opening and closing component 10.

[0106] When multiple optical axes 30 are set, the elastic element 40 can make the pressure surface of the first opening and closing component 10 adapt to the contact surface of the glove blank, so that the pressure of the first opening and closing component 10 is uniform, and the two pressing surfaces of the first opening and closing component 10 and the second opening and closing component 20 are parallel to each other, avoiding the situation that some glove blanks with poor flatness cannot be picked up, and realizing automatic plane correction when pressing down and grabbing.

[0107] Furthermore, a first driving member 104 is provided in the first opening and closing assembly 10. The first driving member 104 is used to control the first clamping member 1012 and the second clamping member 1013 to move away from the fixing member 1014.

[0108] A second drive member 203 is provided in the second opening and closing assembly 20. The second drive member 203 is used to control the third clamping member 2012 and the fourth clamping member 2013 to move closer and further apart from each other.

[0109] Specifically, the first driving member 104 and the second driving member 203 can be configured as a cylinder or other driving device such as an electric one, and the elastic member 40 can be configured as an elastic element with elasticity such as a spring or a rubber pad.

[0110] When the first driving member 104 controls the movement, the first clamping member 1012 and the second clamping member 1013 can slide horizontally and approach each other, or they can rotate with one end as an axis and the other end making a circular motion. Similarly, when the second driving member 203 drives, the third clamping member 2012 and the fourth clamping member 2013 have the same movement mode.

[0111] To achieve the above objectives, this utility model also provides an automatic glove blank loading mechanism, which includes one of the above-mentioned flexible material gripping devices, as well as a sorting device and a blank loading device.

[0112] The sorting device is used to neatly place the glove blanks, so that the glove blanks are arranged in a neat manner and correspond to the position of the gripping parts, which facilitates the gripping parts to grasp them and improves the overall work efficiency.

[0113] The flexible material gripping device is used to grip and move the glove blank and open its opening to facilitate the subsequent fitting of the glove blank onto the blank fitting mechanism.

[0114] The preform insertion device is used to insert the opened glove preform, making it easier to retrieve in subsequent processes.

[0115] The working process of the automatic glove preform mounting mechanism is as follows:

[0116] The control and sorting device sorts multiple glove blanks to facilitate gripping by the flexible material gripping device;

[0117] The first opening and closing component 10 is controlled to move to the sorting device to grab the glove blank, and then moves to the second opening and closing component 20. The first opening and closing component 10 is controlled to move down so that the second opening and closing component 20 contacts and grabs the glove blank. The first opening and closing component 10 is controlled to move away from the second opening and closing component 20. At this time, one side of the glove blank is grabbed by the first opening and closing component 10 and the other side is grabbed by the second opening and closing component 20. As the first opening and closing component 10 moves, the opening of the glove blank is opened.

[0118] The first opening and closing component 10 controls the glove blank to move to the blank-fitting device, inserts the glove blank through the support plate to keep the glove blank open, and moves the support plate to fit the open glove blank onto the hand mold, thus completing the entire process.

[0119] When the automatic glove blank assembly needs to produce glove blanks of different sizes, such as producing thicker glove blanks, the first limiting member 1033 in the first opening and closing assembly 10 is controlled to move backward, increasing the size of the first gap 1011 between the first clamping member 1012 or the second clamping member 1013 and the fixing member 1014. The position of the fixing member 1014 is adjusted so that the size of the first gap 1011 on both sides is the same. At this time, the first gap 1011 can accommodate more glove blank fabric. When the first opening and closing assembly 10 grabs the thicker glove blank, it can clamp it more completely, more firmly and stably.

[0120] Similarly, the second limiting component 2023 needs to be controlled to move backward simultaneously to increase the size of the second gap 2011, so as to achieve a more stable grip on both sides of the glove blank and facilitate the subsequent opening operation.

[0121] When producing thinner glove blanks, the size of the first gap 1011 and the second gap 2011 can be appropriately reduced to avoid problems with the grip being too secure due to excessively large gaps.

[0122] In summary, the overall opening device of this utility model has a simple structure, reducing manufacturing costs. It grips flexible materials by clamping them together with planar surfaces, increasing the contact area and solving the problem of unreliable gripping in traditional suction cup technology. The staggered arrangement of the first gap 1011 and the second gap 2011 allows them to abut against the planar surface, enabling some of the flexible material to enter the gaps when pressure is applied, making gripping easier and more reliable. Furthermore, the inclusion of the first anti-slip structure 1015, the second anti-slip structure 2014, the third anti-slip structure 1016, and the fourth anti-slip structure 2015 increases the friction when clamping flexible materials, further improving gripping stability.
