[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0026] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0027] The pull-out tissue paper of the present application includes an outer packaging and a pull-out tissue paper stack contained in the outer packaging. The outer packaging may be a soft packaging bag (such as a plastic film packaging bag) or a hard packaging box (such as a hard paper box). A pull-out opening is provided on the soft packaging bag or the hard packaging box, through which tissue paper can be pulled out one by one. When the previous tissue paper is pulled out, part of the next tissue paper will be brought out from the pull-out opening to facilitate the user to pull out the next tissue paper. Based on the fact that the tissue paper in the pull-out tissue paper stack in the current pull-out tissue paper is highly homogenized and cannot meet the diversified usage needs of users, the present application improves the pull-out tissue paper stack in the pull-out tissue paper.

[0028] See also Figure 1 , Figure 1FIG2 is a schematic diagram of the structure of the first embodiment of the pull-out tissue stack provided by this application. Pull-out tissue stack 10 includes a plurality of intertwined tissues, wherein the plurality of tissues includes at least a first tissue 11 and a second tissue 12. The first tissue 11 and the second tissue 12 are sequentially intertwined and stacked, and have different properties.

[0029] This embodiment provides different paper towels with different characteristics in the pull-out paper towel stack 10, including at least a first paper towel 11 and a second paper towel 12, so that users can use paper towels with multiple characteristics in the unit package of pull-out paper towels, thereby meeting users' different functional requirements and diversified usage needs for paper towels.

[0030] In this embodiment, having different characteristics can specifically include different appearances, smells, tactile sensations, or functions. Paper towels with different characteristics are those that differ in at least one of appearance, smell, tactile sensation, or additional functions. Appearance includes color, pattern, etc. The pattern includes at least one of embossed patterns, printed patterns, edge patterns, and frame patterns.

[0031] Specifically, the first tissue 11 and the second tissue 12 can have different colors. For example, the first tissue 11 and the second tissue 12 can each be a different solid color tissue, such as blue, pink, yellow, green, white, a primary color, or black. Furthermore, the first tissue 11 and / or the second tissue 12 can be colored tissues. That is, the first tissue 11 can include multiple colors, and the second tissue 12 can include a single color or multiple colors, but the first tissue 11 and the second tissue 12 can have different colors, or different patterns or patterns composed of different colors. In addition to having different colors, the first tissue 11 and the second tissue 12 can also have the same or different patterns, scents, tactile properties, or additional functions.

[0032] In one specific embodiment, the first paper towel 11 and the second paper towel 12 are white and a primary color, respectively. The primary color is the natural color of primary pulp, unbleached and undyed. Primary color paper is made from primary color pulp. White paper is also undyed and made from bleached pulp. Other colors can be obtained by coating or impregnating white paper. For example, a pigment or dye of the corresponding color can be applied to the surface of white paper, or the white paper can be immersed in a pigment or dye of the corresponding color to obtain the corresponding color.

[0033] Furthermore, the first tissue 11 and the second tissue 12 may have different patterns, such as embossed patterns, printed patterns, edge patterns, or frame patterns, and the combination of colors may also form different patterns. Specifically, the different patterns may include animals, plants, colorful graphics, sun / moon / star patterns, and the like.

[0034] Specifically, the edge pressing pattern can be formed on the paper by a edge pressing wheel. When each tissue paper comprises at least two layers of base paper, the edge pressing pattern can be used to laminate the two or more layers of base paper at the side edges to prevent delamination of the multiple layers of base paper.

[0035] The first paper towel 11 and the second paper towel 12 can also have different scents. For example, the first paper towel 11 and the second paper towel 12 can be unscented and scented, respectively, or they can each have a different scent. These different scents can include, for example, various fruit scents, various floral scents, or various food scents, such as peach or blueberry scents. Scenting the first paper towel 11 or the second paper towel 12 can be achieved by adding a scenting substance, such as essence, fragrance, or essential oil, to the surface of the unscented paper.

[0036] Specifically, different tactile sensations can include smooth, soft, fluffy, dry, and moist. Furthermore, different tactile sensations can be achieved by applying different coatings to the paper surface, such as applying a coating agent containing a moisturizing factor to give the paper a moist tactile feel. A smooth or soft tactile sensation can be achieved by applying a predetermined amount of softener to the paper surface, where the softener can be a softener specifically designed for household paper with a glycerin content of at least 60%.

[0037] The first paper towel 11 and the second paper towel 12 can also have different additional functions, such as antibacterial and odor removal. Specifically, antibacterial paper can be obtained by coating the paper surface with a predetermined amount of an antibacterial agent. The antibacterial agent used contains at least 30% of a natural plant extract, such as honeysuckle extract. Deodorizing paper can be imparted with a predetermined amount of an odor removal factor by coating the paper surface.

[0038] It is understandable that the first paper towel 11 and the second paper towel 12 have different properties, and may have only one different property, or may have two or more different properties.

[0039] In this embodiment, the first tissue 11 and the second tissue 12 are stacked in an interlaced manner. That is, the removable tissue stack 10 is stacked in an interlaced manner in the order of first tissue 11, second tissue 12, first tissue 11, and second tissue 12. In other embodiments, the removable tissue stack 10 can also be stacked in an interlaced manner in the order of first tissue 11, first tissue 11, second tissue 12, first tissue 11, first tissue 11, and second tissue 12, or in an interlaced manner in the order of first tissue 11, second tissue 12, second tissue 12, first tissue 11, second tissue 12, and so on. The permutations and combinations of the first tissue 11 and the second tissue 12 included in the removable tissue stack 10 are only partially listed; multiple permutations and combinations are possible and are not listed here. The order of arrangement and combination, the proportion of paper quantity, etc. can be set accordingly according to different demands or different demand frequencies for paper towels with different characteristics and for different user groups, and are not limited here.

[0040] The aforementioned “first tissue 11, second tissue 12”, or “first tissue 11, first tissue 11, second tissue 12”, or “first tissue 11, second tissue 12, second tissue 12” can be considered as a minimum repeating unit. The minimum repeating unit in this application is the tissue unit 100.

[0041] Based on the minimal repeating unit of tissue unit 100, the pull-out tissue stack 10 can be said to include multiple tissue units 100, stacked one on top of the other. Each tissue unit 100 comprises multiple intertwined tissues, including at least a first tissue 11 and a second tissue 12. In other words, the pull-out tissue stack 10 is divided into multiple repeating tissue units 100, each of which is identical. Of course, each tissue unit 100 can include multiple first tissues 11 or multiple second tissues 12, or any combination of first and second tissues 11 and 12. For example, in one embodiment, the number of first and second tissues 11 and 12 in two adjacent tissue units 100 differs. In another embodiment, the adjacent tissues in a tissue unit 100 have different properties, such that two tissues drawn from the tissue unit 100 twice consecutively have different properties. Furthermore, the first and last two paper towels in the paper towel unit 100 have different properties, so that when the entire pull-out paper towel stack 10 is pulled out for use, the paper towel pulled out the first time and the paper towel pulled out the next time have different properties.

[0042] It is understood that each tissue unit 100 includes at least a first tissue 11 and a second tissue 12. In addition to the first tissue 11 and the second tissue 12, the tissue unit 100 may also include other tissues. Specifically, the tissue unit 100 may include a variety of tissues with different characteristics, including but not limited to two, three, four, five, etc., which are not listed here one by one.

[0043] In this embodiment, different paper towels with different characteristics are provided in the pull-out paper towel stack 10, including a first paper towel 11 and a second paper towel 12, so that users can obtain paper towels with different appearances, smells, touches or additional functions when using the paper towels in the pull-out paper towel stack 10, thereby meeting the users' and consumers' multifaceted and diversified sensory needs and usage needs for paper towels in terms of appearance, smell, touch and / or additional functions.

[0044] See Figure 2 , Figure 2 FIG2 is a schematic diagram of the structure of the second embodiment of the removable tissue paper stack provided in this application. The removable tissue paper stack 20 includes multiple tissue paper units 200, which are stacked in layers. Each tissue paper unit 200 includes multiple intertwined tissue paper units. The multiple tissue paper units 200 include a first tissue paper 21, a second tissue paper 22, a third tissue paper 23, and a fourth tissue paper 24. The first tissue paper 21, the second tissue paper 22, the third tissue paper 23, and the fourth tissue paper 24 have different properties.

[0045] The different characteristics can be referred to the relevant description of the first embodiment of this application and will not be repeated here. By providing a first paper towel 21, a second paper towel 22, a third paper towel 23, and a fourth paper towel 24 with different characteristics, this embodiment can meet the multiple and diverse sensory needs and usage requirements of users and consumers for paper towels in terms of appearance, smell, touch, and / or additional functions in a single removable paper towel stack 20.

[0046] In the first and second embodiments of the present application, multiple paper towels are folded in a U-shape. Specifically, each paper towel is folded once to form two flaps, which can be referred to as an upper flap and a lower flap. The lower flap of the first paper towel is located between the two flaps of the second paper towel, and the lower flap of the first paper towel at least partially overlaps the two flaps of the second paper towel.

[0047] Specifically, each paper towel is folded along its midline, the upper fold and lower fold of each paper towel are symmetrical along the midline of the paper towel, the lower fold of the first paper towel is clamped between the upper fold and lower fold of the second paper towel, and the lower fold of the first paper towel partially overlaps or completely overlaps with the upper fold of the second paper towel.

[0048] Of course, the multiple paper towels in the pull-out paper towel stack provided in this application can also be folded in other interlaced ways, such as Z-shaped. Figure 3 , Figure 3 This is a schematic diagram of the structure of the third embodiment of the pull-out tissue stack provided in this application. The pull-out tissue stack 30 includes multiple tissue units 300, which are stacked in layers. Each tissue unit 300 includes multiple tissues folded in a Z-shape. The multiple tissues include a first tissue 31, a second tissue 32, and a third tissue 33, each having different properties.

[0049] Each tissue is folded twice to form three flaps, which can be referred to as an upper flap, a middle flap, and a lower flap. The following example uses a first tissue 31 and a second tissue 32 as an example. If the first tissue 31 and the second tissue 32 are two continuous tissues, the lower flap of the first tissue 31 is sandwiched between the upper flap and the middle flap of the second tissue 32, while the upper flap of the second tissue 32 is sandwiched between the middle flap and the lower flap of the first tissue 31. The upper flap of the second tissue 32 and the lower flap of the first tissue 31 at least partially overlap. This allows a portion of the upper flap of the second tissue 32 to be pulled out of the drawer after the first tissue 31 is removed, making it easier for the user to remove the tissue.

[0050] In this embodiment, by arranging first, second, and third tissues 31, 32, and 33 with different characteristics within a removable tissue stack 30, the multiple, diverse sensory and usage needs of users and consumers regarding tissue appearance, scent, tactile feel, and / or additional functionality can be met within a single removable tissue stack 30. Furthermore, by staggering the multiple tissues in a Z-shape, the removable tissue stack 30 is also convenient for users to remove and use.

[0051] See Figure 4 , Figure 4: is a structural schematic diagram of the fourth embodiment of the pull-out paper towel stack provided in this application. In this embodiment, the pull-out paper towel stack 30 includes a first paper towel unit 41 and a second paper towel unit 42, and the first paper towel unit 41 and the second paper towel unit 42 are stacked. Among them, the first paper towel unit 41 includes a plurality of first paper towels 411, and the second paper towel unit 42 includes a plurality of second paper towels 421. The first paper towels 411 and the second paper towels 421 have different characteristics. Specifically, the first paper towel unit 41 and the second paper towel unit 42 are connected. When the pull-out paper towel stack 30 is used, the paper towels in the first paper towel unit 41 and the second paper towel unit 42 can be continuously extracted, that is, the first paper towel 411 in the first paper towel unit 41 is extracted from the extraction port. After the first paper towel unit 41 is extracted, the second paper towel 421 in the second paper towel unit 42 can be extracted. Of course, the first tissue unit 41 can be composed entirely of the first tissue 411, or can include multiple tissues with different characteristics, with the first tissue 411 being one of them. Similarly, the second tissue unit 42 can be composed entirely of the second tissue 421, or can include multiple tissues with different characteristics, with the second tissue 421 being one of them.

[0052] Furthermore, the outer packaging of the pull-out tissue can be provided with two or more extraction openings, for example, two extraction openings, namely a first extraction opening and a second extraction opening. The first tissue unit 41 is extracted from the first extraction opening, and the second tissue unit 42 is extracted from the second extraction opening. Of course, the pull-out tissue stack 40 in this embodiment can also include a third tissue unit (not shown) or more different tissue units.

[0053] In this embodiment, by providing a first tissue unit 41 and a second tissue unit 42 with tissues of different characteristics, a removable tissue stack 40 can meet the multifaceted and diversified sensory needs and usage requirements of users and consumers for tissues in terms of appearance, smell, touch and / or additional functions.

[0054] In the above-described embodiments of the present application, when the pull-out tissue stack includes multiple tissue units, the outer packaging of the pull-out tissue may include a withdrawal opening, through which the multiple tissue units are withdrawn. In this case, the multiple tissue units may be stacked. Alternatively, the outer packaging of the pull-out tissue may include two or more withdrawal openings, such as two withdrawal openings, namely a first withdrawal opening and a second withdrawal opening, from which the multiple tissue units can be withdrawn. When the multiple tissue units include a first tissue unit and a second tissue unit, the first tissue unit can be withdrawn from the first withdrawal opening, and the second tissue unit can be withdrawn from the second withdrawal opening. In this case, the first tissue unit and the second tissue unit may be stacked or arranged side by side, allowing tissues with different characteristics to be withdrawn from a single pull-out tissue, thereby satisfying the diverse sensory and usage needs of users and consumers for tissues in terms of appearance, smell, touch, and / or additional functions.

[0055] In the above-described embodiments of the present application, each tissue in the pull-out tissue stack may include a single layer of base paper, or may include two or more layers of base paper. Specifically, two or more layers of base paper may be laminated to form a single or single layer of tissue. For example, a pressed edge pattern may be formed on the pressed edges of the two or more layers of base paper to prevent delamination of the multiple layers of base paper.

[0056] In one specific embodiment, each tissue in the pull-out tissue stack comprises at least two layers of base paper, the at least two layers of base paper being stacked, including a first base paper and a second base paper, the first base paper and the second base paper having different properties. That is, each tissue, including the first and second tissues, is formed by stacking two or more layers of base paper. By having first and second base papers with different properties, the pull-out tissue stack includes first and second tissues with different properties, allowing the tissues drawn from the pull-out tissue stack to have base papers with different properties.

[0057] In other specific embodiments, each tissue in the pull-out tissue stack is identical and includes at least two layers of base paper, the at least two layers of base paper are stacked, the at least two layers of base paper include a first base paper and a second base paper, and the first base paper and the second base paper have different properties.

[0058] In the above two specific embodiments, by setting up multiple layers of base paper with different characteristics, base paper with different appearances, smells, touches or additional functions can be obtained, which can meet the user or consumer's multi-faceted and diversified sensory needs and usage needs for paper towels in terms of appearance, smell, touch and / or additional functions in one pull-out paper towel.

[0059] This application also provides a method for manufacturing a pull-out paper towel, see Figure 5 , Figure 5 This is a flow chart of an embodiment of a method for manufacturing a removable tissue provided by the present application. Specifically, it includes:

[0060] S501: Unroll at least two paper rolls; wherein the at least two paper rolls have at least one different characteristic.

[0061] Among them, the at least two paper rolls include two or more paper rolls. The two paper rolls have at least one different characteristic, that is, they can have only one different characteristic, or they can have two or more different characteristics. The different characteristics may specifically include different appearance, smell, touch or function, etc. If at least one of the appearance, smell, touch or additional function is different, then the paper towel has different characteristics. Among them, the appearance includes color, pattern, etc., and the pattern includes at least one of embossed pattern, printed pattern, edge pressing pattern and frame pressing pattern. And the description of different characteristics in the pull-out paper towel stack provided in this application is also applicable to the manufacturing method of this pull-out paper towel stack.

[0062] Furthermore, based on the fact that the paper webs in the at least two paper rolls themselves have at least one different characteristic, after unwinding in S501, the paper web of at least one of the at least two paper rolls may be pretreated at least once to impart at least one different characteristic to the at least two paper rolls. The pretreatment may include coating, embossing, printing, edge pressing, or frame pressing. Pretreatment of the paper web of at least one of the at least two paper rolls at least once means that one or more of the at least two paper rolls are pretreated, while the other one or more paper rolls are not pretreated. Pretreatment of a particular paper roll at least once means that the paper roll may be pretreated once or multiple times, two or more times, to impart one or more different characteristics to the paper roll.

[0063] In one specific embodiment, the paper webs of the first and second paper rolls have different characteristics, such as different colors. After the paper webs of the first and second paper rolls are subjected to an embossing pre-treatment, the paper webs of the first and second paper rolls each have different embossing patterns, such as a fish-shaped embossing and a cloud-shaped embossing, respectively. This pre-treatment imparts different characteristics to the paper webs of the first and second paper rolls.

[0064] In another embodiment, the at least two paper rolls unwound in this step have the same properties. The paper webs of at least one of the at least two paper rolls are pretreated at least once, so that the paper webs of the at least two paper rolls have at least one different property. Pretreatment of the paper web of at least one of the at least two paper rolls at least once means that one or more of the at least two paper rolls are pretreated, while the other one or more paper rolls are not pretreated. Pretreatment of a particular paper roll at least once means that the paper webs of the at least two paper rolls may be pretreated once or may be pretreated twice or more, so that the paper webs of the at least two paper rolls have one or more different properties.

[0065] S502: Cutting the paper webs of at least two paper rolls in a length direction to obtain paper towel segments of a preset length, and folding the paper towel segments alternately into paper towel stacks.

[0066] The paper web length direction X is the tangent direction of the paper roll, see Figure 6 After the paper webs of the two paper rolls are cut into sections of a predetermined length, the sections are alternately folded into a paper towel stack. The folding method can be U-shaped or Z-shaped.

[0067] S503: The paper towel stack is conveyed to the slitting section, and the paper towel stack is slit along the width direction of the paper web.

[0068] The tissues in the target pull-out tissue stack have a specific length and width. This length can be adjusted to the preset length in S502, thus achieving the preset length. In this step, the tissue stack is cut along the width of the tissue to achieve the preset width. Through S502 and S503, a pull-out tissue stack having the preset length and width is obtained.

[0069] After obtaining the pull-out tissue stack, it is necessary to package the pull-out tissue stack to obtain the pull-out tissue of the present application. The packaging method can be soft packaging such as film packaging or hard packaging such as a rigid paper box. Depending on the packaging method, appropriate packaging equipment and packaging methods can be selected to package the pull-out tissue stack, which will not be described in detail here.

[0070] In this embodiment, by unrolling, slitting and folding at least two paper rolls with different characteristics, a pull-out paper towel stack including paper towels with different characteristics is obtained, so that users can obtain paper towels with different characteristics such as different appearance, smell, touch or additional functions in one pull-out paper towel, thereby meeting the multi-faceted and diversified sensory needs and usage needs of users and consumers for paper towels in terms of appearance, smell, touch and / or additional functions.

[0071] The present application also provides a manufacturing device for a pull-out paper towel. Figure 6 , Figure 6 1 is a schematic structural diagram of a first embodiment of a manufacturing apparatus for a removable tissue provided by the present application. Specifically, the manufacturing apparatus 60 comprises: an unwinding unit 61, a folding unit 62, and a slitting unit (not shown).

[0072] The unwinding section 61 includes at least two unwinding racks 611 for unwinding at least two paper rolls 600, and continuously providing at least two paper webs to the folding section 62. The at least two paper rolls 600 have at least one different characteristic. In this embodiment, the at least two paper rolls 600 include two or more paper rolls 600. Different characteristics may specifically include different appearance, smell, touch or functions. If at least one of the appearance, smell, touch or additional functions is different, the paper towel has different characteristics. Appearance includes color, pattern, etc. The description of different characteristics in the pull-out paper towel stack 610 provided in this application is also applicable to the manufacturing equipment 60 of this pull-out paper towel stack.

[0073] The folding section 62 includes at least two slitting and folding roller groups 621 for slitting the paper roll 600 along its length, producing tissue segments of a preset length, which are then alternately folded into a tissue stack. Specifically, the slitting and folding roller group 621 includes a cutter roller 6211 and a folding roller 6212. In one embodiment, the unwinding section 61 includes two unwinding racks 611, which provide two paper webs to the folding section 62. Specifically, the two paper webs pass through the cutter rollers 6211 and folding rollers 6212, respectively, to complete slitting and folding, forming a tissue stack having a preset number of tissue segments. The number of tissue segments in this tissue stack is the same as the number of tissues in the final, target, pull-out tissue stack 610, i.e., the preset number.

[0074] The tissue stack of a predetermined length formed at the folding section 62 is transported to the slitting section for further slitting. The slitting section includes a rotary cutter for slitting the tissue stack along the width of the paper web to obtain a pull-out tissue stack 610 of a predetermined width.

[0075] Furthermore, the manufacturing equipment 60 may also include an outer packaging unit (not shown). The outer packaging unit is used to package the pull-out tissue stack 610 to produce the pull-out tissue. Specifically, the packaging method can be soft packaging such as film packaging or hard packaging such as a rigid paper box. Depending on the packaging method, the corresponding packaging equipment can be selected, which will not be described in detail here.

[0076] In this embodiment, a pull-out tissue stack 610 having a predetermined length and width is obtained by unwinding at least two paper rolls 600 having different characteristics, and by slitting at the folding portion 62 and the slitting portion. Furthermore, the pull-out tissue stack 610 includes tissues having different characteristics, allowing users to obtain tissues with different appearances, scents, tactile sensations, or additional functions from a single pull-out tissue stack 610 or pull-out tissue, thereby satisfying the diverse sensory needs and usage requirements of users and consumers for tissues in terms of appearance, scent, tactile sensation, and / or additional functions.

[0077] In addition to producing a pull-out tissue stack by using at least two paper rolls having at least one different characteristic, the pull-out tissue manufacturing apparatus can also pre-process the same paper roll to produce a paper web having at least one different characteristic, or pre-process at least two paper rolls having at least one different characteristic so that the paper rolls have multiple different characteristics, thereby providing tissues with different characteristics in the pull-out tissue stack. Specifically, see Figure 7 7 is a schematic structural diagram of the second embodiment of the pull-out paper towel manufacturing equipment provided in the present application.

[0078] In this embodiment, the manufacturing equipment 70 specifically includes: an unwinding section 71, a pre-processing section 72, a folding section 73 and a slitting section (not shown).

[0079] The pre-processing section 72 is located between the unwinding section 71 and the folding section 73. The pre-processing section 72 includes at least one pre-processing unit 721 for pre-processing at least one of the at least two paper rolls 700 so that the paper webs of the at least two paper rolls 700 have at least one different characteristic.

[0080] The pre-treatment unit 721 may be a coating unit, an embossing unit, a printing unit, a press unit or a frame pressing unit, etc. The coating unit, the embossing unit, the printing unit, the press unit or the frame pressing unit may be used to coat, emboss, print, press or frame press the paper web.

[0081] Specifically, the coating unit may be a spraying device or a roller coating device, which may apply softeners, antibacterial agents, deodorizing factors, fragrance substances, etc. onto the paper web.

[0082] In a specific embodiment, the paper web of a paper roll 700 is pre-processed by the pre-processing section 72 so that the paper web has different properties from the paper webs of other paper rolls 700 that have not been pre-processed, so that the paper towel stack formed by slitting and folding in the folding section 73 includes paper towel segments with different properties, and the final pull-out paper towel stack 710 includes paper towels with different properties.

[0083] Furthermore, the preprocessing section 72 includes at least one preprocessing unit 721. Specifically, the preprocessing section 72 may include one preprocessing unit 721, or may include two or more preprocessing units 721. When the preprocessing section 72 includes only one preprocessing unit 721, only one paper roll 700 corresponding to the unwinding section 71 will be preprocessed by the preprocessing unit 721, while the paper roll 700 corresponding to the unwinding section 71 will not be preprocessed. When the preprocessing section 72 includes multiple (including two or more) preprocessing units 721, the multiple preprocessing units 721 may correspond to multiple paper rolls 700, thereby preprocessing the paper webs of the multiple paper rolls 700 one by one, thereby imparting different properties to the paper webs of the multiple paper rolls 700. Multiple preprocessing units 721 may also perform multiple or multiple preprocessing operations on the paper web of a single paper roll 700, thereby imparting different properties to the paper webs of the multiple paper rolls 700. That is, the paper web of a single paper roll 700 may correspond to multiple preprocessing units 721. After multiple preprocessing processes in the multiple preprocessing units 721, the paper web of this paper roll 700 may have multiple different properties from the paper webs of other paper rolls 700. In other words, a single preprocessing unit 721 may also include multiple (two or more) preprocessing subunits (not shown). A single paper roll 700 may be preprocessed multiple times by the multiple preprocessing subunits of the preprocessing unit 721. Specifically, the multiple preprocessing subunits may sequentially perform different preprocessing processes on the paper web of the paper roll 700, resulting in the paper web of this paper roll 700 having two or more different properties from the paper webs of other paper rolls 700.

[0084] As for the unrolling portion 71 , the folding portion 73 and the slitting portion in this embodiment, the details may refer to the relevant descriptions of the unrolling portion 61 , the folding portion 62 and the slitting portion in the previous embodiment, which will not be described in detail here.

[0085] The at least two paper rolls 700 include two or more paper rolls 700. The paper webs of the at least two paper rolls 700 have different properties, which may include different appearance, smell, feel, or functionality. Paper towels with different properties are those that differ in at least one of appearance, smell, feel, or additional functionality. Appearance includes color, pattern, etc. The description of different properties in the pull-out paper towel stack provided in this application also applies to the manufacturing equipment 70 for this pull-out paper towel stack 710.

[0086] Furthermore, the manufacturing equipment 70 may also include an outer packaging unit (not shown). The outer packaging unit is used to package the pull-out tissue stack 710 to produce the pull-out tissue. Specifically, the packaging method can be soft packaging such as film packaging or hard packaging such as a rigid paper box. Depending on the packaging method, the corresponding packaging equipment can be selected, which will not be described in detail here.

[0087] In this embodiment, two or more paper rolls 700 are unwound by an unwinding unit 71. The paper webs of the unwound paper rolls 700 may have the same or different properties. At least one of the two or more paper rolls 700 is pre-processed to impart at least one different property to the paper webs of the multiple paper rolls 700. If the unwound paper webs of the multiple paper rolls 700 may have the same properties, the pre-processing unit 72 imparts at least one different property to the paper webs of the multiple paper rolls 700. If the unwound paper webs of the multiple paper rolls 700 may have different properties, the pre-processing unit 72 imparts additional different properties to the paper webs of the multiple paper rolls 700. The paper webs of the multiple paper rolls 700 are then cut and folded by a folding unit 73 and a slitting unit, resulting in a pull-out tissue stack 710 having a predetermined length, width, and quantity. The pull-out tissue stack 710 includes tissues with different characteristics, so that users can obtain tissues with different characteristics such as different appearance, smell, touch or additional functions in one pull-out tissue, meeting the users' and consumers' multi-faceted and diversified sensory needs and usage needs for tissues in terms of appearance, smell, touch and / or additional functions.

[0088] The above description is merely an embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
