Description

Paper pad and forming method thereof Technical Field

[0001] The invention relates to a paper pad and a forming method thereof. Background Art

[0002] Some fragile items may break during transportation due to the vibration and bumps of the vehicle. Currently, fragile items are usually wrapped with paper pads to protect them from collision and shock.

[0003] However, some fragile items have irregular appearances, and after being wrapped with paper pads, the gaps in the packaging box cannot be filled, so the items can still move inside the box, and there is still a risk of damage. In addition, a large amount of paper pads will be consumed, resulting in high costs. Alternatively, when small fragile items are wrapped with paper pads, they are usually wrapped many times, resulting in a large amount of paper pads consumed and high packaging costs.

[0004] Therefore, how to overcome the above technical deficiencies is a technical problem that needs to be solved urgently by those skilled in the art.

[0005] Summary of the Invention

[0006] The purpose of the present invention is to provide a paper pad and a forming method thereof.

[0007] According to one aspect of the present invention, there is provided a paper pad, comprising a pad material,

[0008] The mat material is uneven.

[0009] The cushion material is provided with a shrinkage portion, and the shrinkage portion is provided with a locking structure for preventing the shrinkage portion from loosening.

[0010] The locking structure on the wrinkled portion of the paper pad of the present invention can prevent the wrinkled portion on the pad material from loosening, ensuring that the paper pad always remains compact, thereby improving the cushioning effect of uneven pad materials. The paper pad of the present invention can be used to fill the corner space of packaging boxes in logistics to ensure that items will not move in the packaging box. It is also suitable for wrapping and shock-absorbing small-volume items, with a small usage amount and cost savings. In addition, the paper pad can be divided into different specifications according to the needs of the scene, and can also be used in the packaging cushioning of other larger-volume objects.

[0011] In some embodiments, the two sides of the cushion material located at the wrinkled portion can form a first body and a second body respectively.

[0012] The locking structure may include a first extension and a perforation provided on the crimped portion,

[0013] One end of the first extension portion is provided on either the first body or the second body.

[0014] The other end of the first extension portion is arranged obliquely after passing through the through hole, or the other end of the first extension portion is attached to the other of the first body and the second body after passing through the through hole.

[0015] Therefore, after passing through the perforation, the first extension portion is arranged at an angle or attached to one of the first body and the second body. In this way, the first extension portion can lock the wrinkled portion to prevent the wrinkled portion on the pad material from loosening, ensuring that the paper pad always remains compact, thereby improving the cushioning effect of the pad material.

[0016] In some embodiments, the two sides of the cushion material located at the wrinkled portion can form a first body and a second body respectively.

[0017] The locking structure may include a second extension portion, one end of the second extension portion is arranged on either the first body or the second body, the second extension portion is overlapped on the wrinkled portion, and the other end of the second extension portion is arranged at an acute angle to the other of the first body and the second body or the other end of the second extension portion is attached to the other of the first body and the second body.

[0018] Therefore, after the second extension portion is overlapped on the wrinkled portion, its free end is arranged at an acute angle to one of the first body and the second body or attached to one of the first body and the second body. In this way, the second extension portion can lock the wrinkled portion to prevent the wrinkled portion on the pad material from loosening, ensuring that the paper pad always remains compact, thereby improving the cushioning effect of the pad material.

[0019] In some embodiments, the two sides of the cushion material located at the wrinkled portion can form a first body and a second body respectively.

[0020] The locking structure may include a second extension portion and a through-slot portion provided on the wrinkled portion, one end of the second extension portion is provided on either the first body or the second body, the second extension portion is accommodated in the through-slot portion, the other end of the second extension portion is arranged at an acute angle to the other of the first body and the second body or the other end of the second extension portion is attached to the other of the first body and the second body.

[0021] Thus, after the second extension portion is accommodated in the through groove portion on the wrinkled portion, its free end is arranged at an acute angle to one of the first body and the second body or attached to one of the first body and the second body. In this way, the second extension portion can lock the wrinkled portion to prevent the wrinkled portion on the cushion material from loosening, ensuring that the paper cushion always remains compact, thereby improving the cushioning effect of the cushion material.

[0022] In some embodiments, the locking structure can be formed by folding the wrinkled portion at least twice. Thus, after folding the wrinkled portion at least twice, the wrinkled portion on the mat material is less likely to loosen, ensuring that the paper mat remains compact, thereby improving the cushioning effect of the mat material.

[0023] In some embodiments, the locking structure can be formed by folding the wrinkled portion in half. Thus, after the wrinkled portion is folded in half, the wrinkled portion on the mat material is not easy to loosen, ensuring that the paper mat remains compact, thereby improving the cushioning effect of the mat material.

[0024] In some embodiments, the locking structure can be formed by bending the wrinkled portion. Thus, after the wrinkled portion is bent, the wrinkled portion on the mat material is not easy to loosen, ensuring that the paper mat remains compact, thereby improving the cushioning effect of the mat material.

[0025] In some embodiments, the locking structure can be formed by bonding the cushioning materials within the crumpled portion together. Thus, the cushioning materials within the crumpled portion can be bonded together to lock the crumpled portion, preventing the crumpled portion on the cushioning material from loosening, ensuring that the paper cushioning material always remains compact, and thus improving the cushioning effect of the cushioning material.

[0026] In some embodiments, the third body and the fourth body are formed on both sides of the mat material, respectively.

[0027] The locking structure can be formed by the third body being in a V shape or by folding the third body in half.

[0028] Therefore, when the third body is in a V-shape or the third body is folded in half, the wrinkled portion on the cushion material is not easy to loosen, ensuring that the paper cushion remains compact, thereby improving the cushioning effect of the cushion material.

[0029] In some embodiments, the third body and the fourth body may be formed on both sides of the mat material, respectively.

[0030] The locking structure may be formed by the fourth body being in a V shape or by the fourth body being folded in half.

[0031] Therefore, when the fourth body is in a V-shape or the fourth body is folded in half, the wrinkled portion on the cushion material is not easy to loosen, ensuring that the paper cushion remains compact, thereby improving the cushioning effect of the cushion material.

[0032] In some embodiments, the third body and the fourth body are formed on both sides of the mat material, respectively.

[0033] The locking structure can be formed by the third body being planar and the fourth body being V-shaped, or by the third body being planar and the fourth body being folded in half.

[0034] Therefore, the third body is planar and the fourth body is V-shaped or the third body is planar and the fourth body is folded in half, which can prevent the wrinkled part on the pad from loosening, ensure that the paper pad remains compact, and thus improve the cushioning effect of the pad.

[0035] In some embodiments, the third body and the fourth body may be formed on both sides of the mat material, respectively.

[0036] The locking structure can be formed by the fourth body being planar and the third body being V-shaped, or by the fourth body being planar and the third body being folded in half.

[0037] Therefore, the fourth body is planar and the third body is V-shaped or the fourth body is planar and the third body is folded in half, which can prevent the wrinkled part on the cushion material from loosening, ensure that the paper cushion remains compact, and thus improve the cushioning effect of the cushion material.

[0038] In some embodiments, the mat material may be wrinkled, or the surface of the mat material may be serrated, or the surface of the mat material may be wavy, or the surface of the mat material may be ridged. Thus, the wrinkled, serrated, wavy, or ridged surface mat material can ensure the cushioning effect of the mat material.

[0039] In some embodiments, the wrinkle direction of the wrinkle portion can be along the width or length of the mat material. Thus, when the wrinkle direction of the wrinkle portion is along the width of the mat material, the wrinkle portion can be formed by squeezing the middle area of ​​the mat material from both sides and clamping, squeezing, or compressing the middle area of ​​the mat material. When the wrinkle direction of the wrinkle portion is along the length of the mat material, the mat material can be first cut into a plurality of sub-mats of a certain length along the length direction, and then the middle area of ​​each sub-mat can be clamped, squeezed, or compressed along the length direction of the mat material to form the wrinkle on the sub-mat.

[0040] According to another aspect of the present invention, there is also provided a method for forming a paper pad, comprising the following steps:

[0041] a. Conveying mat materials;

[0042] b. Wrinkle the mat material;

[0043] c. Extruding the mat material to form a wrinkle to increase the wrinkle density in the area where the wrinkle is located;

[0044] d. Separate the extruded mat material into paper mats of required length.

[0045] The forming method of the present invention can ensure that the wrinkled part formed by extruding the cushion material can ensure that the paper cushion remains compact, thereby improving the cushioning effect of the uneven cushion material. The formed paper cushion can be used to fill the corner space of the packaging box in logistics, ensuring that the items will not move in the packaging box. It is also suitable for wrapping and shock-absorbing small-volume items, with small usage and cost savings. In addition, the paper cushion can be divided into different specifications according to the needs of the scene, and can also be used in the packaging cushioning of other larger-volume objects.

[0046] In some embodiments, the following steps may be further included after step c:

[0047] c '. The shrinkage portion is locked by piercing the shrinkage portion with teeth or a needle, and the tongue formed is fitted on one side of the shrinkage portion or arranged at an acute angle to the shrinkage portion.

[0048] Therefore, in this way, the wrinkled portion can be locked to prevent the wrinkled portion on the mat material from loosening, ensuring that the paper pad always remains compact, thereby improving the cushioning effect of the mat material.

[0049] In some embodiments, the following steps may be further included after step c:

[0050] c '. The shrinkage portion is locked, and the locking method is: folding the shrinkage portion, and the shrinkage portion is folded at least twice.

[0051] Thus, after the wrinkled portion is folded at least twice, the wrinkled portion on the mat material is not easy to become loose, ensuring that the paper mat remains compact, thereby improving the cushioning effect of the mat material.

[0052] In some embodiments, the following steps may be further included after step c:

[0053] c'. Lock the wrinkled portion by folding the wrinkled portion in half.

[0054] Thus, after the wrinkled portion is folded in half, the wrinkled portion on the cushion material is not easy to become loose, thereby ensuring that the paper cushion remains compact, thereby improving the cushioning effect of the cushion material.

[0055] In some embodiments, the following steps may be further included after step c:

[0056] c'. Lock the wrinkled portion by squeezing the wrinkled portion into a V shape.

[0057] Therefore, after the wrinkled portion is squeezed into a V shape, the wrinkled portion on the mat material is not easy to loosen, ensuring that the paper mat remains compact, thereby improving the cushioning effect of the mat material.

[0058] In some embodiments, the following steps may be further included after step c:

[0059] c'. Lock the wrinkled portion by folding one side of the wrinkled portion in half.

[0060] Thus, by folding one side of the wrinkled portion in half, the wrinkled portion on the mat material can be prevented from becoming loose, thereby ensuring that the paper mat remains compact, thereby improving the cushioning effect of the mat material.

[0061] In some embodiments, the following steps may be further included after step c:

[0062] c'. Lock the wrinkled portion by keeping one side of the wrinkled portion flat and the other side in a V shape or folded in half.

[0063] Therefore, by keeping one side of the wrinkled portion flat and the other side V-shaped or folded in half, the wrinkled portion on the mat material is not easy to loosen, ensuring that the paper mat remains compact, thereby improving the cushioning effect of the mat material.

[0064] In some embodiments, the following steps may be further included after step c:

[0065] c'. Lock the wrinkled portion by providing a buckling portion on the wrinkled portion, wherein one end of the buckling portion is fixed to one side of the wrinkled portion, the buckling portion is buckled to the wrinkled portion, and the other end of the buckling portion is arranged at an acute angle to the other side of the wrinkled portion or attached to the other side of the wrinkled portion.

[0066] Thus, the buckling portion can lock the wrinkled portion, preventing the wrinkled portion on the cushion material from loosening, ensuring that the paper cushion always remains compact, thereby improving the cushioning effect of the cushion material.

[0067] In some embodiments, the following steps may be further included after step c:

[0068] c '. The wrinkled portion is locked by tearing off a portion of the wrinkled portion, folding the torn portion so that it is arranged at an acute angle to one side of the wrinkled portion or attaching it to one side of the wrinkled portion.

[0069] Thus, the torn portion of the wrinkled portion can lock the wrinkled portion, preventing the wrinkled portion on the mat material from loosening, ensuring that the paper mat always remains compact, thereby improving the cushioning effect of the mat material.

[0070] In some embodiments, the following steps may be further included after step c:

[0071] c'. Lock the wrinkled portion by taping the wrinkled portion.

[0072] Thus, the wrinkled portion can be locked after being bound by the adhesive tape, thereby preventing the wrinkled portion on the mat material from becoming loose and ensuring that the paper mat always remains compact, thereby improving the cushioning effect of the mat material.

[0073] In some embodiments, the method may further include the following steps after step b:

[0074] b'. Apply glue to the trough of the wrinkles in the middle area of ​​the mat.

[0075] In step c, when the middle area of ​​the mat material is squeezed, the wrinkles in the middle area of ​​the mat material adhere to each other to form a wrinkled portion.

[0076] Thus, the wrinkles in the middle area of ​​the mat material are bonded together to form a wrinkled portion, which can prevent the mat material from becoming loose at the wrinkled portion, ensuring that the paper pad always remains compact, thereby improving the cushioning effect of the mat material.

[0077] In some embodiments, in step a, the mat material may be corrugated, or the surface of the mat material may be serrated, or the surface of the mat material may be wavy, or the surface of the mat material may be ridged. Thus, a mat material having a corrugated, serrated, wavy, or ridged surface can ensure a cushioning effect.

[0078] In some embodiments, in step c, the wrinkle direction of the wrinkled portion can be along the width or length of the mat material. Thus, when the wrinkle direction of the wrinkled portion is along the width of the mat material, the wrinkle can be formed by squeezing the middle region of the mat material from both sides and clamping, squeezing, or compressing the middle region of the mat material. When the wrinkle direction of the wrinkle direction is along the length of the mat material, the mat material can be first cut into several sub-mats of a certain length along the length direction, and then the middle region of each sub-mat can be clamped, squeezed, or compressed along the length direction of the mat material to form the wrinkle on the sub-mat.

In addition, the paper pad can be divided into different specifications according to the needs of the scene, and can also be used in the packaging cushioning of other larger-volume objects.

[0129] Embodiment 5:

[0130] FIG6 schematically shows the structure of a paper pad according to a fifth embodiment of the present invention.

[0131] Reference 6, a paper pad includes a pad material 1.

[0132] In this embodiment, only the locking structure is different from that of the fourth embodiment, and the rest are the same and will not be described in detail.

[0133] Referring to Figure 6, in this embodiment, the locking structure can be formed by folding the wrinkled portion 11 in half. The formation process of the wrinkled portion 11 can refer to the style changes of Figure 1 → Figure 6; after the wrinkled portion 11 is folded in half, the wrinkled portion 11 on the pad material 1 can be prevented from loosening, ensuring that the paper pad remains compact, thereby improving the cushioning effect of the pad material 1.

[0134] In other embodiments, the locking structure can also be formed by bending the wrinkled portion 11. After the wrinkled portion 11 is bent, the wrinkled portion 11 on the pad material 1 is not easy to loosen, ensuring that the paper pad remains compact, thereby improving the cushioning effect of the pad material 1.

[0135] In other embodiments, the locking structure can also be formed by bonding the pad materials 1 located in the wrinkled portion 11 to each other. The locking structure can be formed by: dripping glue at the trough of the wrinkles in the middle area of ​​the pad material 1, and then squeezing the middle area of ​​the pad material 1. The wrinkles in the middle area of ​​the pad material 1 are bonded to each other to form a locking structure to lock the wrinkled portion 11. After the pad materials 1 in the wrinkled portion 11 are bonded to each other, the wrinkled portion 11 can be locked to prevent the wrinkled portion 11 on the pad material 1 from loosening, ensuring that the paper pad always remains compact, thereby improving the cushioning effect of the pad material 1.

[0136] The locking structure on the wrinkled portion 11 of the paper pad of the present invention can prevent the wrinkled portion 11 on the pad material 1 from loosening, ensuring that the paper pad always remains compact, thereby improving the cushioning effect of the uneven pad material 1. The paper pad of the present invention can be used to fill the corner space of the packaging box in logistics to ensure that the items will not move in the packaging box. It is also suitable for wrapping and shock-absorbing small-volume items, with a small usage amount and cost savings. In addition, the paper pad can be divided into different specifications according to the needs of the scene, and can also be used in the packaging cushioning of other larger-volume objects.

[0137] Example 6:

[0138] FIG. 7 schematically shows the structure of a paper pad according to a sixth embodiment of the present invention.

[0139] Reference 7, a paper pad includes a pad material 1.

[0140] The mat material 1 is uneven. Specifically, the style of the mat material 1 can be selected: the mat material 1 is wrinkled, or the surface of the mat material 1 is serrated, or the surface of the mat material 1 is wavy, or the surface of the mat material 1 is tile-edge-shaped. The mat material 1 with wrinkles, serrated surfaces, wavy surfaces, and tile-edge-shaped surfaces can ensure the cushioning effect of the mat material 1.

[0141] 7 , a shrinkage portion 11 is formed on the mat material 1 . The shrinkage portion 11 is in a gathered shape and can be formed by clamping, squeezing, or compressing the middle region of the mat material 1 .

[0142] Referring to Figure 7, the wrinkling direction of the shrinkage portion 11 can be along the width direction of the mat 1 or along the length direction of the mat 1. When the wrinkling direction of the shrinkage portion 11 is along the width direction of the mat 1 (the up and down direction shown in Figure 7), the middle area of ​​the mat 1 is squeezed from the upper and lower sides of the mat 1, and the middle area of ​​the mat 1 is clamped, squeezed / compressed to form the wrinkle portion 11. When the wrinkling direction of the shrinkage portion 11 is along the length direction of the mat 1 (the left and right direction shown in Figure 7), the mat 1 can be cut into several sub-mats of a certain length along the length direction, and then the middle area of ​​each sub-mat is clamped, squeezed / compressed along the length direction of the mat 1 to form the wrinkle portion 11 on the sub-mat.

[0143] A locking structure is provided on the wrinkled portion 11, which can prevent the wrinkled portion 11 on the mat material 1 from becoming loose, ensuring that the paper pad always remains compact, thereby improving the cushioning effect of the uneven mat material 1.

[0144] 7 , a third body 103 and a fourth body 104 are formed on two sides of the mat material 1 .

[0145] 7 , in this embodiment, the locking structure is formed by a third body 103 in a V shape. The V shape of the third body 103 can prevent the wrinkled portion 11 on the mat material 1 from becoming loose, thereby ensuring that the paper pad remains compact and improving the cushioning effect of the mat material 1 .

[0146] In other embodiments, the locking structure can also be formed by folding the third body 103 in half. After the third body 103 is folded in half, the wrinkled portion 11 on the mat material 1 is not easy to loosen, ensuring that the paper pad remains compact, thereby improving the cushioning effect of the mat material 1.

[0147] In other embodiments, the locking structure can also be formed by the fourth body 104 being in a V shape, or the fourth body 104 being folded in half. The fourth body 104 being in a V shape or the fourth body 104 being folded in half can make the wrinkled portion 11 on the pad material 1 less likely to loosen, ensuring that the paper pad remains compact, thereby improving the cushioning effect of the pad material 1.

[0148] In other embodiments, the locking structure can also be formed by the third body 103 being planar and the fourth body 104 being V-shaped, or the third body 103 being planar and the fourth body 104 being folded in half, or the fourth body 104 being planar and the third body 103 being V-shaped, or the fourth body 104 being planar and the third body 103 being folded in half. In this way, the wrinkled portion 11 on the pad material 1 is not easy to loosen, ensuring that the paper pad remains compact, thereby improving the cushioning effect of the pad material 1.

[0149] The locking structure on the wrinkled portion 11 of the paper pad of the present invention can prevent the wrinkled portion 11 on the pad material 1 from loosening, ensuring that the paper pad always remains compact, thereby improving the cushioning effect of the uneven pad material 1. The paper pad of the present invention can be used to fill the corner space of the packaging box in logistics to ensure that the items will not move in the packaging box. It is also suitable for wrapping and shock-absorbing small-volume items, with a small usage amount and cost savings. In addition, the paper pad can be divided into different specifications according to the needs of the scene, and can also be used in the packaging cushioning of other larger-volume objects.

[0150] FIG8 schematically shows the process of a method for forming a paper pad according to an embodiment of the present invention.

[0151] Referring to FIG8 , the method for forming a paper pad includes the following steps:

[0152] S101: Conveying cushion materials.

[0153] S102: wrinkling the mat material;

[0154] The mat material can be wrinkled by passing the mat material through a wave-shaped forming channel, by pressing the mat material through upper and lower wave-shaped rollers or pressure plates, or by extrusion molding through front and rear differential wheels.

[0155] The direction of wrinkling the mat material can be along the width direction of the mat material, or along the length direction of the mat material. Of course, wrinkling can be along any other direction of the mat material without special limitation.

[0156] The wrinkled mat material is uneven. Specifically, the style of the wrinkled mat material can be selected as follows: the mat material is wrinkled, or the surface of the mat material is serrated, or the surface of the mat material is wavy, or the surface of the mat material is tile-edge-shaped. Mat materials with wrinkled, serrated, wavy, and tile-edge surfaces can ensure the cushioning effect of the mat material.

[0157] S103: compressing the mat material to form a wrinkled portion to increase the wrinkling density in the area where the wrinkled portion is located;

[0158] The middle area of ​​the mat material is clamped and squeezed / compressed. Preferably, the squeezing direction coincides with the wrinkling direction. A cylinder-driven clamping member can be used to squeeze the mat material. The squeezing direction can also not coincide with the wrinkling direction, but be inclined at a certain angle. During the process of squeezing the mat material to form a wrinkled portion, the wrinkling density in the area where the wrinkled portion is located increases, thereby ensuring the cushioning effect of the mat material.

[0159] The wrinkling direction of the wrinkled portion can be along the width direction or the length direction of the mat. When the wrinkling direction of the wrinkled portion is along the width direction of the mat, the middle area of ​​the mat is squeezed from both sides of the mat, and the middle area of ​​the mat is clamped, squeezed / compressed to form the wrinkled portion. When the wrinkling direction of the wrinkled portion is along the length direction of the mat, the mat can be first cut into several sub-mats of a certain length along the length direction. The two adjacent sub-mats can be completely cut or incompletely cut. When they are incompletely cut, only the middle area between the two adjacent sub-mats is cut to facilitate extrusion to form the wrinkled portion. Then, the middle area of ​​each sub-mat is clamped, squeezed / compressed along the length direction of the mat to form the wrinkled portion on the sub-mat.

[0160] S104: separating the extruded mat material into paper mats of required lengths;

[0161] A tear line, an indentation or a tear line can be set on the mat material in advance, and the extruded mat material can be separated into paper mats of required length by tearing or cutting.

[0162] The forming method of the present invention can ensure that the wrinkled part formed by extruding the cushion material can ensure that the paper cushion remains compact, thereby improving the cushioning effect of the uneven cushion material. The formed paper cushion can be used to fill the corner space of the packaging box in logistics, ensuring that the items will not move in the packaging box. It is also suitable for wrapping and shock-absorbing small-volume items, with small usage and cost savings. In addition, the paper cushion can be divided into different specifications according to the needs of the scene, and can also be used in the packaging cushioning of other larger-volume objects.

[0163] FIG9 schematically shows the process of a method for forming a paper pad according to another embodiment of the present invention.

[0164] Referring to FIG9 , the method for forming a paper pad includes the following steps:

[0165] S201: Conveying cushion materials.

[0166] S202: wrinkling the mat material;

[0167] The mat material can be wrinkled by passing the mat material through a wave-shaped forming channel, by pressing the mat material through upper and lower wave-shaped rollers or pressure plates, or by extrusion molding through front and rear differential wheels.

[0168] The direction of wrinkling the mat material can be along the width direction of the mat material, or along the length direction of the mat material. Of course, wrinkling can be along any other direction of the mat material without special limitation.

[0169] The wrinkled mat material is uneven. Specifically, the style of the wrinkled mat material can be selected as follows: the mat material is wrinkled, or the surface of the mat material is serrated, or the surface of the mat material is wavy, or the surface of the mat material is tile-edge-shaped. Mat materials with wrinkled, serrated, wavy, and tile-edge surfaces can ensure the cushioning effect of the mat material.

[0170] S203: compressing the mat material to form a wrinkled portion to increase the wrinkling density in the area where the wrinkled portion is located;

[0171] The middle area of ​​the mat material is clamped and squeezed / compressed. Preferably, the squeezing direction coincides with the wrinkling direction. A cylinder-driven clamping member can be used to squeeze the mat material. The squeezing direction can also not coincide with the wrinkling direction, but be inclined at a certain angle. During the process of squeezing the mat material to form a wrinkled portion, the wrinkling density in the area where the wrinkled portion is located increases, thereby ensuring the cushioning effect of the mat material.

[0172] The wrinkling direction of the wrinkled portion can be along the width direction or the length direction of the mat. When the wrinkling direction of the wrinkled portion is along the width direction of the mat, the middle area of ​​the mat is squeezed from both sides of the mat, and the middle area of ​​the mat is clamped, squeezed / compressed to form the wrinkled portion. When the wrinkling direction of the wrinkled portion is along the length direction of the mat, the mat can be first cut into several sub-mats of a certain length along the length direction. The two adjacent sub-mats can be completely cut or incompletely cut. When they are incompletely cut, only the middle area between the two adjacent sub-mats is cut to facilitate extrusion to form the wrinkled portion. Then, the middle area of ​​each sub-mat is clamped, squeezed / compressed along the length direction of the mat to form the wrinkled portion on the sub-mat.

[0173] S204: Locking the shrinkage portion;

[0174] The locking mode can be:

[0190] or,

[0191] The wrinkled portion is bound with adhesive tape. Specifically, the adhesive tape may be applied to the trough of the wrinkles in the middle region of the mat material. Then, in step S203, when the middle region of the mat material is squeezed, the wrinkles in the middle region of the mat material are bonded to each other. The adhesive tape may be applied manually or by an apparatus.

[0192] After locking the wrinkled portion by the above method or other methods capable of locking the wrinkled portion, the wrinkled portion on the mat material can be prevented from loosening, ensuring that the paper mat always remains compact, thereby improving the cushioning effect of the mat material.
