It should be understood that the use of the directional terms should not limit the scope of protection requested in the present application.First Embodiment

[0066] As shown in FIG. 1 to FIG. 7, a first embodiment of the present application provides a method for manufacturing curtain bodies, which includes the following steps:

[0067] S1, providing at least one fabric layer 1; wherein the fabric layer 1 is a rectangular sheet-like structure, and the fabric layer 1 has a length direction L, a first width direction W, and a first thickness direction H, of which every two are perpendicular to each other.

[0068] S2, performing stacking processing for the fabric layer 1 along the first thickness direction H thereof to obtain a stacked body 6 having multiple stacking layers 10, wherein the multiple stacked layers 10 stack sequentially along the first thickness direction H; and performing compositing processing for adjacent stacking layers 10 of the stacked body 6 to make adjacent stacking layers 10 be connected together (as shown in FIG. 5g, adjacent stacking layers 10 refer to two stacking layers 10 stacked adjacently along the first thickness direction H).

[0069] Among them, each of the stacking layers 10 is provided with multiple first composite part 101 and multiple second composite parts 102, the first composite parts 101, the second composite parts 102, and the stacking layer 10 (the fabric layer 1) are an integrated structure; the first composite parts 101 and the second composite parts 102 continuously extend along the length direction L of the fabric layer 1 respectively (that is, the first composite parts 101 and the second composite parts 102 are all long strip structures extending along the length direction L), and the multiple first composite parts 101 and the multiple second composite parts 102 are set sequentially, alternately, and at intervals along the first width direction W of the fabric layer 1 (i.e., along the first width direction W, the first composite parts 101 and the second composite parts 102 are arranged in stagger); the multiple first composite parts 101 of every two adjacent stacking layers 10 are in one-to-one correspondence, and the multiple second composite parts 102 of every two adjacent stacking layers 10 are in one-to-one correspondence.

[0070] Along the first thickness direction H, in every three adjacent stacking layers 10, the multiple first composite parts 101 of two adjacent stacking layers 10 are interconnected (that is, the multiple first composite parts 101 of one of the stacking layers 10 are connected in one-to-one correspondence with the multiple first composite parts 101 of the other of the stacking layers 10), and the multiple second composite parts of other two adjacent stacking layers are interconnected (that is, the multiple second composite parts 102 of one of the stacking layers 10 are connected in one-to-one correspondence with the multiple second composite parts 102 of the other of the stacking layers 10); there is no connection between other parts of adjacent stacking layers 10.

[0071] S3, cutting the stacked body 6 to obtain multiple cut bodies 62, wherein the cut bodies 62 are curtain bodies 7 (multiple cut bodies 62 are multiple curtain bodies 7); moreover, the curtain bodies 7 can be unfolded and folded.

[0072] In the method for manufacturing curtain bodies provided by this embodiment of the present application, by performing stacking processing for the fabric layer 1 along the first thickness direction H thereof, a stacked body 6 having multiple stacking layers 10 is obtained; and compositing processing is performed for adjacent stacking layers 10 in the stacked body 6, so that in every three adjacent stacking layers 10, the multiple first composite parts 101 of two adjacent stacking layers 10 are interconnected, and the multiple second composite parts 102 of other two adjacent stacking layers 10 are interconnected; in this way, it is made that there are multiple curtain body structures in the stacked body 6; by the subsequent cutting step, the stacked body 6 can be divided into multiple cut bodies 62, thereby obtaining multiple curtain bodies 7. The method for manufacturing curtain bodies not only has simple process, simplifies the production process flow, and facilitates reducing production costs, but also manufactures to obtain curtain bodies 7 in stable and reliable structures; there will be no misalignment or positional deviation between adjacent folding units above and below in the curtain bodies 7, thereby improving the production efficiency, service life, and aesthetics of the curtain bodies 7.

[0073] In the step S2, this embodiment performs stacking processing for the fabric layer 1 along the first thickness direction H, and performs compositing processing for the adjacent stacking layers 10 in the stacked body 6 at the same time. Of course, in other embodiments, it is also possible to first perform stacking processing for the fabric layer 1 along the first thickness direction H, and then perform compositing processing for the adjacent stacking layers 10 in the stacked body 6.

[0074] As an implementation, both the number of the first composite parts 101 and the number of the second composite parts 102 are greater than or equal to three.

[0075] As shown in FIG. 1 to FIG. 7, as an implementation, in the step S2, adjacent stacking layers 10 in the stacked body 6 are bonded and fixed through glue layers. Specifically, along the first thickness direction H, in every three adjacent stacking layers 10, the multiple first composite parts 101 of two adjacent stacking layers 10 are bonded through multiple first glue layers 3 respectively (that is, the multiple first composite parts 101 of one of the stacking layers 10 are respectively bonded through multiple first glue layers 3 in one-to-one correspondence with the multiple first composite parts 101 of the other of the stacking layers 10), and the multiple second composite parts 102 of other two adjacent stacking layers 10 are bonded through multiple second glue layers 4 respectively (that is, the multiple second composite parts 102 of one of the stacking layers 10 are respectively bonded through multiple second glue layers 4 in one-to-one correspondence with the multiple second composite parts 102 of the other of the stacking layers 10).

[0076] As shown in FIG. 1 to FIG. 7, as an implementation, in the step S1, the at least one fabric layer 1 includes a first fabric layer 11 and a second fabric layer 12, the first fabric layer 11 and the second fabric layer 12 are arranged spacedly and oppositely, from top to bottom, and the first fabric layer 11 is located above the second fabric layer 12; wherein both the first fabric layer 11 and the second fabric layer 12 are rectangular sheet-like structures, and shapes and length and width sizes of the first fabric layer 11 and the second fabric layer 12 are the same (thicknesses and colors may be the same and may also be different; preferably, thicknesses and colors of the two are the same).

[0077] The step S2 specifically includes:

[0078] setting multiple first glue layers 3 and multiple second glue layers 4 on the first fabric layer 11 and / or the second fabric layer 12; wherein the first glue layers 3 are set on a bottom surface of the first fabric layer 11 and / or a top surface of the second fabric layer 12 (that is, the first glue layers 3 are set on mutually close surfaces of the first fabric layer 11 and / or the second fabric layer 12), the second glue layers 4 are set on a top surface of the first fabric layer 11 and / or a bottom surface of the second fabric layer 12 (that is, the second glue layers 4 are set on mutually back-facing surfaces of the first fabric layer 11 and / or the second fabric layer 12); the multiple first glue layers 3 are in correspondence (one-to-one correspondence) with the multiple first composite parts 101 respectively, the multiple second glue layers 4 are in correspondence (one-to-one correspondence) with the multiple second composite parts 102 respectively; the first glue layers 3 and the second glue layers 4 continuous extend along the length direction L respectively (that is, the first glue layers 3 and the second glue layers 4 are all long strip structures extending along the length direction L), and the multiple first glue layers 3 and the multiple second glue layers 4 are set sequentially, alternately, and at intervals along the first width direction W (that is, along the first width direction W, the first glue layers 3 and the second glue layers 4 are arranged in stagger);

[0079] combining the first fabric layer 11 and the second fabric layer 12, so that the first fabric layer 11 and the second fabric layer 12 are bonded together through the multiple first glue layers 3, thereby making multiple first composite parts 101 of adjacent stacking layers 10 be respectively bonded through the multiple first glue layers 3 and form a bonded body 5 (since the first glue layers 3 are set on mutually close surfaces of the first fabric layer 11 and the second fabric layer 12, when the bottom surface of the first fabric layer 11 and the top surface of the second fabric layer 12 are in contact, the two can be bonded together through the first glue layers 3);

[0080] winding the bonded body 5 to obtain the stacked body 6 in a cylindrical structure, wherein the stacked body 6 includes multiple winding loops (not labeled in the drawings); during the winding process, bonding adjacent winding loops in the stacked body 6 are bonded together through the multiple second glue layers 4, so that multiple second composite parts 102 on adjacent stacked layers 10 are respectively bonded through the multiple second glue layers 4.

[0081] Specifically, during the winding process, since the bonded body 5 will be wound circle by circle and thereby form multiple winding loops arranged from inside to outside sequentially (each winding loop has two stacking layers 10), and at the same time, the second glue layers 4 are set on mutually back-facing surfaces of the first fabric layer 11 and the second fabric layer 12, adjacent winding loops will be bonded together through the multiple second glue layers 4 during the winding process; that is, as shown in FIG. 5g, adjacent stacking layers 10 are either bonded together by the multiple first glue layers 3 or bonded together by the multiple second glue layers 4, thereby obtaining the stacked body 6 in a cylindrical structure.

[0082] In other words, in this embodiment, aforesaid “performing stacking processing for the fabric layer 1 along the first thickness direction H thereof” is actually performing winding processing for the fabric layer 1 along the length direction L, thereby forming the stacked body 6 having multiple stacking layers 10 (of course, in other embodiments, it is also possible to form the multiple stacking layers 10 in other ways, such as folding the fabric layer 1 back and forth multiple times along the length direction L). Aforesaid “processing compositing processing for adjacent stacking layers 10 of the stacked body 6” is actually performing bonding processing between adjacent stacking layers 10 of the stacked body 6, so that adjacent stacking layers 10 are bonded together through glue layers.

[0083] As shown in FIG. 1 to FIG. 5c and FIG. 7, as an implementation, the first glue layers 3 are set on the bottom surface of the first fabric layer 11, and the second glue layers 4 are set on the top surface of the first fabric layer 11, that is, the first glue layers 3 and the second glue layers 4 are set on the first fabric layer 11 at the same time. As shown in FIG. 8, as another implementation, the first glue layers 3 are set on the top surface of the second fabric layer 12, and the second glue layers 4 are set on the top surface of the first fabric layer 11. As shown in FIG. 9, as another implementation, the first glue layers 3 are set on both the bottom surface of the first fabric layer11 and the top surface of the second fabric layer 12, and the second glue layers 4 are set on both the top surface of the first fabric layer 11 and the bottom surface of the second fabric layer 12.

[0084] Of course, in other embodiments, the first glue layers 3 and the second glue layers 4 can also be in other setting manners, such as setting both the first glue layers 3 and the second glue layers 4 on the second fabric layer 12, etc., as long as it is ensured that at least one of the bottom surface of the first fabric layer 11 and the top surface of the second fabric layer 12 is provided with the first glue layers 3, at least one of the top surface of the first fabric layer 11 and the bottom surface of the second fabric layer 12 is provided the second glue layers 4, and the first glue layers 3 and the second glue layers 4 are arranged alternately.

[0085] As an implementation, both the number of the first glue layers 3 and the number of the second glue layers 4 are greater than or equal to three.

[0086] As shown in FIG. 1 and FIG. 5a to FIG. 5c, as an implementation, in the step S2, it is possible to first set the multiple first glue layers 3 and the multiple second glue layers 4 on the first fabric layer 11 and / or the second fabric layer 12, and then performing combination for the first fabric layer 11 and the second fabric layer 12.

[0087] Of course, in other embodiments, it is also possible to first set the multiple first glue layers 3 on the first fabric layer 11 and / or the second fabric layer 12, perform combination for the first fabric layer 11 and the second fabric layer12, and then set the multiple second glue layers 4 on the first fabric layer 11 and / or the second fabric layer 12, as long as it is ensured that the glue applying step for the first glue layers 3 is before the combining step for the first fabric layer 11 and the second fabric layer 12, and the glue applying step for the second glue layers 4 is before the winding step.

[0088] Moreover, the glue applying step for the first glue layers 3 and the glue applying step for the second glue layers 4 do not need to be distinguished before and after. It is possible to first perform the glue applying step for the first glue layers 3 and then perform the glue applying step for the second glue layers 4, and it is also possible to first perform the glue applying step for the second glue layers 4 and then perform the glue applying step for the first glue layers 3, or perform the glue applying step for the first glue layers 3 and the glue applying step for the second glue layers 4 at the same time.

[0089] As shown in FIG. 1 to FIG. 5c, as an implementation, in the step S2, the multiple first glue layers 3 and the multiple second glue layers 4 are respectively formed by rolling using a first dandy roll 821 and a second dandy roll 822 on the first fabric layer 11 and / or the second fabric layer 22.

The glue applying device 82 includes aforesaid first dandy roll 821, aforesaid second dandy roll 822, a glue guide roll 823, and a glue storage trough 824. The first dandy roll 821, the second dandy roll 822, and the glue guide roll 823 can rotate, the glue storage trough 824 stores liquid glue material (i.e., liquid adhesive) therein, the glue guide roll 823 is partially dipped in the glue material in the glue storage trough 824, and the glue guide roll 823, when rotating, can adhere the glue material in the glue storage trough 824 onto a surface of the glue guide roll 823. The multiple first circular protrusions 8212 are in one-to-one correspondence with the multiple first glue layers 3 respectively, and the multiple second circular protrusions 8222 are in one-to-one correspondence with the multiple second glue layers 4 respectively.

[0093] When applying glue, the multiple first circular protrusions 8212 of the first dandy roll 821 contact the bottom surface of the first fabric layer 11 and the outside surface of the glue guide roll 823 respectively, and the multiple second circular protrusions 8222 of the second dandy roll 822 contact the top surface of the first fabric layer 11 and the outside surface of the glue guide roll 823 respectively (FIG. 4 does not show the glue guide roll 823 in contact with the second dandy roll 822); at the same time, the first dandy roll 821, the second dandy roll 822, and the glue guide roll 823 rotate, and the first fabric layer 1 flows backwards. When the multiple first circular protrusions 8212 of the first dandy roll 821 contact the outside surface of the glue guide roll 823, the glue material on the surface of the glue guide roll 823 adheres to the multiple first circular protrusions 8212; when the multiple first circular protrusions 8212 contact the bottom surface of the first fabric layer 11, the glue material on the multiple first circular protrusions 8212 is imprinted (rolled-in) onto the bottom surface of the first fabric layer 11 respectively, thereby forming the multiple continuous first glue layers 3 respectively. When the multiple second circular protrusions 8212 of the second dandy roll 822 contact the outside surface of the glue guide roll 823, the glue material on the surface of the glue guide roll 823 adheres to the multiple second circular protrusions 8222; when the multiple second circular protrusions 8222 contact the top surface of the first fabric layer 11, the glue material on the multiple second circular protrusions 8222 is imprinted (rolled-in) onto the top surface of the first fabric layer 11 respectively, thereby forming the multiple continuous second glue layers 4 respectively. Among them, this embodiment adopts the way of first using the glue guide roll 823 to adhere the glue material and then adhering the glue material onto the first circular protrusions 8212 or the second circular protrusions 8222, which is intended to avoid the first circular protrusions 8212 or the second circular protrusions 8222 from being in direct contact with the glue material in the glue storage trough 84 and being prone to cause problems that the glue material on the first circular protrusions 8212 or the second circular protrusions 8222 may drip or distribute unevenly, etc., thereby improving uniformity of glue applying. Among them, the drawings of this embodiment show that the first dandy roll 821 is provided with four first circular protrusions 8212, and the second dandy roll 822 is provided with three second circular protrusions 8222, thereby forming four first glue layers 3 and three second glue layers 4 on the first fabric layer 11 respectively. In fact, the numbers of the first circular protrusions 8212 and of the second circular protrusions 8222 may be more, generally more than ten, thereby obtaining more first glue layers 3 and second glue layers 4; the numbers of the first glue layers 3 and of the second glue layers 4 are generally more than ten.

[0094] Of course, in other embodiments, it is also possible to dispose the multiple first glue layers 3 and the multiple second glue layers 4 on the first fabric layer 11 and / or the second fabric layer 12 through glue applying devices 82 of other ways or other structural types.

[0095] As shown in FIG. 1 and FIG. 5b to FIG. 5c, as an implementation, in the step S2, the combining the first fabric layer 11 and the second fabric layer 12, so that the first fabric layer 11 and the second fabric layer 12 are bonded together through the multiple first glue layers 3 specifically includes:

[0096] using a roll pressing assembly 83 to perform roll pressing for the first fabric layer 11 and the second fabric layer 12, so that the bottom surface of the first fabric layer 11 is in contact with the top surface of the second fabric layer 12, and the bottom surface of the first fabric layer 11 and the top surface of the second fabric layer 12 are bonded together through the multiple first glue layers 3.

[0097] Specifically, in this embodiment, the roll pressing assembly 83 includes an upper roller (not labeled in the drawings) and a lower roller which are set oppositely from top to bottom, the upper roller is located above the lower roller, and rotating directions of the upper roller and the lower roller are reverse. The first fabric layer 11 and the second fabric layer 12 pass between the upper roller and the lower roller when flowing backwards, the upper roller and the lower roller apply certain pressure on the first fabric layer 11 and the second fabric layer 12, so that the bottom surface of the first fabric layer 11 is in contact with and bonded together through the multiple first glue layers 3 with the top surface of the second fabric layer 12, thereby forming the bonded body 5. Of course, in other embodiments, it is also possible to combine the first fabric layer 11 and the second fabric layer 12 through other methods or apparatuses.

[0098] As shown in FIG. 1 and FIG. 5c to FIG. 5d, as an implementation, in the step S2, a winding device 84 is specifically used to wind the bonded body 5. When winding, the winding device 84 rotates (the winding device 84 can not only rotate clockwise but also rotate counterclockwise), the bonded body 5 is sequentially wound on the winding device 84 along the length direction L to form multiple winding loops, and the winding loops are bonded together through the multiple second glue layer 4 to obtain the stacked body 6 in a cylindrical structure. In this embodiment, the winding device 84 is a cylindrical structure (may be a hollow cylindrical structure or a solid cylindrical structure), so that the stacked body 6 forms a cylindrical structure (i.e., a structure similar to a roll of toilet paper). Of course, in other embodiments, the winding device 84 can also be structures in other shapes, for example, be a multi-prism structure, at this time, the stacked body 6 forms a polygonal cylindrical structure (for example, the winding device 84 is a hexagonal prism structure, at this time, the stacked body 6 forms a hexagonal cylindrical structure). After winding is completed, the stacked body 6 is removed from the winding device 84.

[0099] As another implementation, in the step S2, adjacent stacking layers 10 in the stacked body 6 are connected through ultrasonic composition, specifically, an ultrasonic composite machine can be adopted to connect adjacent stacking layers 10 together. Specifically, along the first thickness direction H, in every three adjacent stacking layers 10, the multiple first composite parts 101 of two adjacent stacking layers 10 are connected through ultrasonic composition (that is, the multiple first composite parts 101 of one of the stacking layers 10 are respectively connected in one-to-one correspondence with the multiple first composite parts 101 of the other of the stacking layers 10 in the way of ultrasonic composition), and the multiple second composite parts 102 of other two adjacent stacking layers 10 are connected through ultrasonic composition (that is, the multiple second composite parts 102 of one of the stacking layers 10 are respectively connected in one-to-one correspondence with the multiple second composite parts 102 of the other of the stacking layers 10 in the way of ultrasonic composition).

[0100] As another implementation, in the step S2, adjacent stacking layers 10 in the stacked body 6 are connected through thermal compression composition, specifically, a thermal compression machine can be adopted to connect adjacent stacking layers 10 together. Specifically, along the first thickness direction H, in every three adjacent stacking layers 10, the multiple first composite parts 101 of two adjacent stacking layers 10 are connected through thermal compression composition (that is, the multiple first composite parts 101 of one of the stacking layers 10 are respectively connected in one-to-one correspondence with the multiple first composite parts 101 of the other of the stacking layers 10 in the way of thermal composition compression), and the multiple second composite parts 102 of other two adjacent stacking layers 10 are connected through thermal compression composition (that is, the multiple second composite parts 102 of one of the stacking layers 10 are respectively connected in one-to-one correspondence with the multiple second composite parts 102 of the other of the stacking layers 10 in the way of thermal composition compression).

[0101] As shown in FIG. 5e to FIG. 5j, as an implementation, in the step S3, the cutting the stacked body 6 specifically includes:

[0102] cutting the stacked body 6 along a first cutting plane M and a second cutting plane N, wherein the first cutting plane M is parallel to both the first width direction W and the first thickness direction H (that is, in this embodiment, the first cutting plane N is parallel to an end surface 60 of the stacked body 6 with the cylindrical structure), the second cutting plane N is perpendicular to the first width direction W and parallel to the first thickness direction H (that is, in this embodiment, the second cutting plane N is parallel to the end surface 60 of the stacked body 6 with the cylindrical structure), that is, the first cutting plane M is perpendicular to the second cutting plane N; the second cutting plane N passes through the first composite parts 101 or the second composite parts 102 (that is, in this embodiment, the second cutting plane N passes through the first glue layers 3 or the second glue layers 4).

[0103] Among them, as shown in FIG. 5e to FIG. 6b, the position of the first cutting plane M determines the final width a of a single curtain body 7, the position of the second cutting plane N determines the final thickness b and the shape of a single curtain body 7, and the number of the stacking layers 10 in the stacked body 6 (i.e., the number of winding circles of the bonded body 5) determines the height c of a single curtain body unfolded.

[0104] Among them, both the numbers of the first cutting plane M and of the second cutting plane N are multiple, the multiple first cutting planes M are arranged spacedly, the multiple second cutting planes N are arranged spacedly, so that multiple cut bodies 62 can be obtained after cutting, and thus multiple curtain bodies 7 are obtained once.

[0105] As shown in FIG. 5g and FIG. 5h, as an implementation, when cutting, along the first width direction W, the second cutting plane N passes through middle positions of the first composite parts 101 or middle positions of the second composite parts 102 (that is, the second cutting plane N passes through the middle positions of the first glue layers 3 or the middle portions of the second glue layer 4), so that the first composite parts 101 or the second composite parts 102 can be averagely distributed to two curtain bodies 7 at two sides of the second cutting plane N, thereby making shapes and sizes of the two curtain bodies 7 keep consistent, and making both the two curtain bodies 7 have good structural strength. At the same time, since the second cutting plane N needs to pass through the first composite parts 101 or the second composite parts 102, the first composite parts 101 and the second composite parts 102 need to have sufficient widths to ensure that adjacent layers 10 (i.e., adjacent first fabric layer 11 and second fabric layer 12) have sufficient connection area and connection strength at cut positions.

[0106] As shown in FIG. 5e to FIG. 5j, as an implementation, specific cutting steps for the stacked body 6 can be:

[0107] (1) as shown in FIG. 5e to FIG. 5f, first cutting the stacked body 6 along a certain first cutting plane M, so that the stacked body 6 can be unfolded from a cylindrical structure to an approximately rectangular structure after being cut;

[0108] (2) as shown in FIG. 5f to FIG. 5h, cutting the stacked body 6 along multiple spaced first cutting planes M to obtain multiple intermedium bodies 61;

[0109] (3) as shown in FIG. 5g to FIG. 5j, cutting the multiple intermedium bodies 61 along multiple spaced second cutting planes N to obtain multiple cut bodies 62.

[0110] Among them, the sequences of the step (2) and the step (3) can be exchanged, and it is also possible to perform the step (2) on one hand and perform the step (3) on the other hand.

[0111] The above only exemplarily describe a kind of cutting manner; of course, in other embodiments, it is also possible to adopt other manners and steps to cut the stacked body 6.

[0112] As shown in FIG. 5i to FIG. 6b, as an implementation, when unfolding the curtain body 7, it is only necessary to pull an upper end of the curtain body 7, so that the curtain body 7 naturally hangs downwards. Under the action of the gravity of the curtain body 7 itself, the curtain body 7 can be unfolded (it is also possible to pull upper and lower ends of the curtain body 7 and apply force to upper and lower sides respectively to make the curtain body 7 unfold). The curtain body 7 has multiple folding units (not labeled in the drawings), each folding unit is roughly diamond shaped, and the multiple folding units in the curtain body 7 are connected from top to bottom in sequence. During the unfolding process, unconnected parts of adjacent first fabric layer 11 and second fabric layer 12 (i.e. adjacent stacking layers 10) in the curtain body 7 will separate, thereby forming a cavity 700, that is, a cavity 700 is formed in each folding unit; mutually connected parts of the first fabric layer 11 and the second fabric layer 12 in the curtain body 7 will form folded edges of the folding units and connection parts between folding units which are adjacent from top to bottom.

[0113] As shown in FIG. 5g to FIG. 6b, as an implementation, in the step S4, the number of the second cutting plane N is multiple; two adjacent second cutting planes N pass through two different columns of first composite parts 101 respectively (as shown in FIG. 5g, along the first thickness direction H, first composite parts 101 located at the same vertical line forms a column; that is, in two adjacent second cutting planes N, one of the second cutting planes N passes through one column of first composite parts 101, the other of the second cutting planes N passes through another column of first composite parts 101; the two columns of first composite parts 101 may be adjacent, and may also be not adjacent), that is, the two adjacent second cutting planes N pass through two different columns of first glue layers 3 respectively, so that the curtain body 7 forms a honeycomb curtain body 7A. Alternatively, two adjacent second cutting planes N can also pass through two different columns of second composite parts 102 respectively (along the first thickness direction H, second composite parts 102 located at the same vertical line forms a column), that is, the two adjacent second cutting planes N pass through two different columns of second glue layers 4 respectively, it is also possible to make the curtain body 7 form a honeycomb curtain body 7A. Alternatively, as shown in FIG. 12a to FIG. 12c, two adjacent second cutting planes N can also respectively pass through a column of first composite parts 101 and a column of second composite parts 102 which are not adjacent, that is, the two adjacent second cutting planes N respectively pass through a column of first glue layers 3 and a column of second glue layers 4 which are not adjacent, it is also possible to make the curtain body 7 form a honeycomb curtain body 7A.

[0114] At the same time, as shown in FIG. 5g to FIG. 6b, in this embodiment, two adjacent second cutting planes N pass through two adjacent columns of first composite parts 101 respectively, that is, the two adjacent second cutting planes N pass through two adjacent columns of first glue layers 3 respectively, the curtain body 7 is formed as a single-layer honeycomb curtain body structure (that is, there is only one layer of cavities 700 along the first thickness direction of the curtain body 7). Of course, when two adjacent second cutting planes N pass through two adjacent columns of second composite parts 102 respectively, that is, the two adjacent second cutting planes N pass through two adjacent columns of second glue layers 4 respectively, the curtain body 7 can also be formed as a single-layer honeycomb curtain body structure.

[0115] As shown in FIG. 12a to FIG. 12c, in another embodiment, two adjacent second cutting planes N respectively pass through a column of first composite parts 101 and a column of second composite parts 102 which are not adjacent, that is, the two adjacent second cutting planes N respectively pass through a column of first glue layers 3 and a column of second glue layers 4 which are not adjacent, the curtain body 7 forms a multi-layer honeycomb curtain body structure (that is, multiple layers of cavities 700 are formed along the first thickness direction of the curtain body 7, the drawings show two layers of cavities 700 formed).

[0116] As shown in FIG. 11a to FIG. 11c, in another embodiment, two adjacent second cutting planes N respectively pass through two adjacent columns of second composite parts 102 which are not adjacent, that is, the two adjacent second cutting planes N respectively pass through two adjacent columns of second glue layers 4 which are not adjacent, the curtain body 7 forms a multi-layer honeycomb curtain body structure (the drawings show three layers of cavities 700 formed). Of course, when two adjacent second cutting planes N respectively pass through two adjacent columns of first composite parts 101 which are not adjacent, that is, the two adjacent second cutting planes N respectively pass through two adjacent columns of first glue layers 3 which are not adjacent, the curtain body 7 can also form a multi-layer honeycomb curtain body structure.

[0117] As shown in FIG. 10a to FIG. 10c, in another embodiment, two adjacent second cutting planes N respectively pass through a column of first composite parts 101 and a column of second composite parts 102 which are adjacent, that is, the two adjacent second cutting planes N respectively pass through a column of first glue layers 3 and a column of second glue layers 4 which are adjacent; at this time, there is only one connection part between stacking layers 10 in the cut body 62 which are adjacent from top to bottom (i.e., the first fabric layer 11 and the second fabric layer 12 which are adjacent from top to bottom), so that the curtain body 7 is formed as a multi-folded curtain body 7B (the multi-folded curtain body 7B includes multiple folding units with roughly “<” structures, and there is no cavity formed in the folding units). At the same time, since the first composite parts 101 and the second composite parts 102 have certain widths, the connection part between the stacking layers 10 which are adjacent from top to bottom also has a certain width, thus it is possible to punch at the positions of folding edges of the multi-folded curtain body 7B (i.e., at the connection part between between the stacking layers 10 which are adjacent from top to bottom), and make a pulling rope 7C pass through bores at the positions of folding edges, thereby realizing folding of the multi-folded curtain body 7B. Therefore, it is not necessary to punch at the folding units of the multi-folded curtain body 7B, and aesthetic of the multi-folded curtain body 7B can be improved.

[0118] As shown in FIG. 7, as an implementation, in the step S2, along the first width direction W, a width A1 of the first composite part 101 and a width A2 of the second composite part 102 are equal, and distances A3 between adjacent first composite parts 101 and second composite parts 102 are all equal; that is, the multiple first composite parts 101 and the multiple second composite parts 102 are set alternately, spacedly, and equidistantly, thereby ensuring consistence of structures of the curtain bodies 7 and facilitating production. Specifically, in this embodiment, a width of the first glue layer 3 is equal to the width A1 of the first composite part 101, a width of the second glue layer 4 is equal to the width A2 of the second composite part 102, that is, the width of the first glue layer 3 and the width of the second glue layer 4 are equal; distances between adjacent first glue layers 3 and second glue layers 4 are all equal, that is, the multiple first glue layers 3 and the multiple second glue layers 4 are set alternately, spacedly, and equidistantly.

[0119] As shown in FIG. 7, as an implementation, along the first width direction W, both the width A1 of the first composite part 101 and the width A2 of the second composite part 102 are 3 mm-10 mm. Both the width of the first glue layer 3 and the width of the second glue layer 4 are 3 mm-10 mm.

[0120] As shown in FIG. 7, as an implementation, in the step S2, along the first width direction W, a distance A4 between adjacent first composite parts 101 is 10 mm-50 mm, a distance A5 between adjacent second composite parts 102 is 10 mm-50 mm, the distance A4 between adjacent first composite parts 101 and the distance A5 between adjacent second composite parts 102 are equal. A distance between adjacent first glue layers 3 is 10 mm-50 mm, a distance between adjacent second glue layers 4 is 10 mm-50 mm, the distance between adjacent first glue layers 3 and the distance between adjacent second glue layers 4 are equal.

[0121] As shown in FIG. 7, as an implementation, in the step S2, along the first width direction W, an edge position of at least one side of the stacking layer 10 (the fabric layer 1) is provided with the first composite parts 101 and / or the second composite parts 102. Preferably, edge positions of two opposite sides of the stacking layer 10 (the fabric layer 1) are provided with the first composite parts 101 and / or the second composite parts 102, so that the whole (or almost the whole) fabric layer 1 can be cut to form the curtain bodies 7, waste is reduced so as to improve fabric's utilization.

[0122] Specifically, in this embodiment, in the step S2, along the first width direction W, an edge position of at least one side of the first fabric layer 11 and / or an edge position of at least one side of the second fabric layer 12 are provided with the first glue layers 3 and / or the second glue layer 4. Preferably, edge positions of two opposite sides of the first fabric layer 11 and / or edge positions of two opposite sides of the second fabric layer 12 are provided with the first glue layers 3 and / or the second glue layer 4, so that the whole (or almost the whole) first fabric layer 11 and second fabric layer 12 can be cut to form the curtain bodies 7, so as to improve fabric's utilization.

[0123] An embodiment of the present application further provides a curtain body 7, which is made using the method for manufacturing curtain bodies described above.

[0124] As shown in FIG. 1 to FIG. 6b, as an implementation, a curtain body manufacturing apparatus 8 can be used to manufacture aforesaid curtain bodies 7. The curtain body manufacturing apparatus 8 includes an unfolding device 81, the glue applying device 82, the roll pressing assembly 83, the winding device 84, and a cutting device (not shown in the drawings). The unfolding device 81 includes a first unfolding shaft (not labeled in the drawings) used to unfold the first fabric layer 11 and a second unfolding shaft (not labeled in the drawings) used to unfold the second fabric layer 12 (not labeled in the drawings). Specifically manufacturing steps for the curtain bodies 7 can be:

[0125] (1) as shown in FIG. 1 and FIG. 5a, a first fabric layer roll and a second fabric layer roll are respectively placed on the first unfolding shaft and the second unfolding shaft, and the first unfolding shaft and the second unfolding shaft rotate to make the first fabric layer 11 and the second fabric layer 12 flow backwards.

[0126] (2) as shown in FIG. 1 and FIG. 5b, the glue applying device 82 is used to roll and apply on the first fabric layer 11 and the second fabric layer 12 to form multiple first glue layers 3 and multiple second glue layers 4.

[0127] (3) as shown in FIG. 1 and FIG. 5c, the roll pressing assembly 83 is used to perform roll pressing for the first fabric layer 11 and the second fabric layer 12, so that the bottom surface of the first fabric layer 11 is in contact with the top surface of the second fabric layer 12, and the bottom surface of the first fabric layer 11 and the top surface of the second fabric layer 12 are bonded together through the multiple first glue layers 3 to obtain the bonded body 5.

[0128] (4) as shown in FIG. 1 and FIG. 5d, the winding device 84 is used to wind the bonded body 5. When winding, the winding device 84 rotates, the bonded body 5 is sequentially wound on the winding device 84 along the length direction L to form multiple winding loops, and the winding loops are bonded together through the multiple second glue layers 4, thereby obtaining the stacked body 6 with a cylindrical structure. After winding is completed, the stacked body 6 is removed from the winding device 84.

[0129] (5) as shown in FIG. 5e to FIG. 5j, the cutting device is used to cut the stacked body 6 to further obtain multiple cut bodies 62, the multiple cut bodies 62 are multiple curtain bodies 7. An unfolded structure of a curtain body 7 is as shown in FIG. 6a and FIG. 6b. Second Embodiment

[0130] As shown in FIG. 13a to FIG. 13f, an embodiment of the present application provides a curtain body 7, which has a second width direction X, a second thickness direction Y, and a height direction Z, of which every two are perpendicular to each other. The curtain body 7 includes multiple curtain pieces 70 arranged sequentially along the height direction Z, each of the curtain pieces 70 is provided with multiple first combination parts 701 and multiple second combination parts 702, the first combination parts 701, the second combination parts 702, and the curtain piece 70 are an integrated structure, and the multiple first combination parts 701 and the multiple second combination parts 702 are set sequentially, alternately, and at intervals along the second thickness direction Y (that is, along the second thickness direction Y, the first combination parts 701 and the second combination parts 702 are arranged in stagger). Both the first combination parts 701 and the second combination parts 702 continuously extend along the second width direction X (that is, both the first combination parts 701 and the second combination parts 702 are long strip structures extending along the second width direction X).

[0131] Along the height direction Z, the multiple first combination parts 701 of every two adjacent curtain pieces 70 are in one-to-one correspondence, and the multiple second combination parts 702 of every two adjacent curtain pieces 70 are in one-to-one correspondence. Among them, adjacent curtain pieces 70 means two curtain pieces 70 that are adjacent and stacked along the height direction Z.

[0132] Along the height direction Z, in every three adjacent curtain pieces 70, the multiple first combination parts 701 of two adjacent curtain pieces 70 are connected in one-to-one correspondence (that is, the multiple first combination parts 701 of one of the curtain pieces 70 are connected in one-to-one correspondence with the multiple first combination parts 701 of the other of the curtain pieces 70), and the multiple second combination parts 702 of other two adjacent curtain pieces 70 are connected in one-to-one correspondence (that is, the multiple second combination parts 702 of one of the curtain pieces 70 are connected in one-to-one correspondence with the multiple second combination parts 702 of the other of the curtain pieces 70), while there is no connection between other parts of adjacent curtain pieces 70, so that the curtain body 7 forms a multi-layer honeycomb structure along the second thickness direction Y (that is, along the second thickness direction Y, multiple layers of cavities 700 are formed in the curtain body 7).

[0133] Among them, every two adjacent curtain pieces 70 respectively form multiple connection parts 70A arranged spacedly at the multiple first combination parts 701 or at the multiple second combination parts 702. As shown in FIG. 13a and FIG. 13b, when the curtain body 7 is unfolded, every two adjacent curtain pieces 70 form cavities 700 between adjacent connection parts 70A, that is, a structure of multiple layers of cavities 700 is formed in the curtain body 7 (FIG. 13a and FIG. 13b show a structure of three layers of cavities 700 formed in the curtain body 7).

[0134] Existing curtain bodies of honeycomb curtains are generally single-layer honeycomb structures, which means that there is only one layer of cavity in a curtain body along a thickness direction of the curtain body, making the structure of the curtain body be relatively simple and lacking in aesthetics, light shielding and sound insulation performance, and thermal insulation and temperature keeping performance.

[0135] In the curtain body 7 provided by this embodiment of the present application, the multiple curtain pieces 70 are disposed, each curtain piece 70 is spacedly and alternately provided with the multiple first combination parts 701 and the multiple second combination parts 702; in every three adjacent curtain pieces 70, the multiple first combination parts 701 of two adjacent curtain pieces 70 are connected in one-to-one correspondence, and the multiple second combination parts 702 of other two adjacent curtain pieces 70 are connected in one-to-one correspondence, so that the curtain body 7 form a multi-layer honeycomb structure, that is, multiple layers of cavities 700 are formed in the curtain body 7. When the curtain body 7 with the multi-layer honeycomb structure is used as a finished product, not only is richness of the structure of the curtain body 7 improved, thereby further improving aesthetic of the curtain body 7, but also shading and sound insulation performance, thermal insulation and temperature keeping performance, and so on of the curtain body 7 can be improved.

[0136] Of course, the curtain body 7 with the multi-layer honeycomb structure can also be used as a semi-finished product. By cutting the curtain body 7, various other curtain bodies with different structures can be obtained. For example, by cutting the curtain body 7, the curtain body structures as shown in FIG. 6a, FIG. 10c, or FIG. 12c are obtained. When cutting the curtain body 7, since the cutting plane needs to pass through the first combination parts 701 or the second combination parts 702, the first combination parts 701 and the second combination parts 702 need to have sufficient widths, that is, the connection part 70A need to have a sufficient width, so as to ensure that there are sufficient connection area and connection strength at the cut positions between adjacent curtain pieces 70 after cutting.

[0137] Therefore, the curtain body 7 with the multi-layer honeycomb structure in this embodiment can not only directly used as a finished product but also used as a semi-finished product to be cut into multiple smaller curtain bodies, so that multiple curtain bodies can be obtained once, thereby improving production efficiency.

[0138] As shown in FIG. 13a to FIG. 13f, as an implementation, in each of the curtain pieces 70, the number of one of the first combination parts 701 and the second combination parts 702 is not less than three, and the number of the other is not less than two, so that the curtain body 7 forms a honeycomb curtain body structure with at least three layers. In this embodiment, in each of the curtain pieces 70, the number of the first combination parts 701 is three, and the number of the second combination parts 702 is two. Of course, in other embodiments, both the numbers of the first combination parts 701 and of the second combination parts 702 can also be two, at this time, the curtain body 7 forms a honeycomb curtain body structure with two layers.
