  Hereinafter, the best mode for carrying out the tissue and the carton-containing tissue of the present invention and the manufacturing method thereof will be described in detail with reference to the drawings. However, the present invention broadly encompasses products and manufacturing methods having the invention-specific matters, and is not limited to the following embodiments.

[1] Tissue and its manufacturing method:
In the tissue manufacturing method of the present invention, as shown in FIG. 1A, the edge emboss 8A is formed only on one end E3 side of the ply 4A, and the edge emboss is not formed on the other end E4 side of the ply 4A. There is a feature in the point.

  As shown in FIG. 3, in the conventional manufacturing method, in order to form the two embossed portions 38 </ b> B, the force from the convex embossed surface 37 </ b> B is applied to two places in an extremely narrow region. Therefore, the base papers 32c and 32d were easily damaged at the two embossed portions 38B of the long wide ply 34B and the gaps. In addition, in this manufacturing method, after forming the embossed portion 38B, the slit portion 42 provided with the round blade 46 is used to cut the gap between the two embossed portions 38B that have been damaged, whereby the long wide ply 34B is obtained. It was necessary to carve out. Therefore, if the crepe is disturbed in the base paper, the ply is easily broken or broken when the embossed portion 38B is formed or when the long wide ply 34B is cut.

  Further, in the manufacturing method described above, the embossed portion 38B is formed in the portion corresponding to the both end portions E5 and E6 of the obtained tissue. It was not solved. Therefore, the resulting tissue was easily broken or broken due to the dub.

  On the other hand, in the manufacturing method of the present invention, as shown in FIG. 1A, since the number of embossed portions 38A itself is small, there are few places where force is applied to the long wide ply 34A from the convex embossed surface 37A. . Further, the embossed portions 38A are formed with a wide space corresponding to the tissue length L1. Therefore, the damage to the long wide ply 34A can be reduced, and there is no need to separate the gap portion of the embossed portion. According to such a method, when the embossed portion 38A is formed or when the long wide ply 34A is cut, the long wide ply 34A is not easily broken or broken.

  Further, as shown in FIG. 1A, in order to form the embossed portion 38A only in the portion corresponding to the end E3 of the obtained tissue, even if the base papers 32a and 32b are bonded in a dubbed state, a subsequent cutting step The dub is eliminated. Therefore, it is possible to solve the problem that the resulting tissue is broken or broken due to the dub.

  The tissue manufacturing method of the present invention includes three steps as an essential step: an embossed portion forming step, a cutting step, and a cutting step. In the following, description will be made separately.

[1-1] Embossed part forming step:
The “embossed portion forming step” is a step of forming an embossed portion on a long wide ply that is a raw material of tissue.

  Specifically, as in the embossed portion forming step 30 shown in FIG. 1A, an interval I1 corresponding to the tissue length L1 along the longitudinal direction of the long wide ply 34A in which a plurality of base papers 32a and 32b are stacked. Thus, the belt-like embossed portion 38A is formed at a plurality of locations.

  By forming the embossed portion 38A at an interval I1 corresponding to the tissue length L1, one embossed portion 38A is formed on each tissue 1 obtained. After that, by cutting the long wide ply 34A along one edge of the embossed portion 38A, a band-shaped edge emboss is formed along one end E3 of the ply 4A, and the other end E4. It is possible to obtain a tissue 1 in which no edge embossing is formed.

  As long as the above conditions are satisfied, the formation method of the embossed portion 38A is not particularly limited. However, as shown in FIGS. 1A and 1B, the long wide ply 34A fed out in the longitudinal direction is sandwiched between the convex embossing wheel 36A engraved with the convex embossed pattern and the receiving roll 35. It is preferable that the embossed portion 38 </ b> A is formed by pressing.

  The structure of the convex embossing roll is not particularly limited. In the method shown in FIG. 1A, a single pressing surface is formed, and the pressing surface uses a convex embossing wheel 36A which is a convex embossing surface 37A on which a convex embossing pattern is formed.

  However, in the manufacturing method of the present invention, as in the method shown in FIG. 4, two pressing surfaces are formed, one pressing surface is a convex embossing surface 37A on which the convex embossing pattern is formed, and the other pressing surface is a plain surface. It is also preferable to use a convex embossing wheel 36C that is the surface 37C. In such a method, the embossed portion 38A can be formed while lightly pressing the long wide ply 34A by the plane surface 37C.

  In the manufacturing method of the present invention, the embossed portion is formed in a strip shape. The “strip shape” means that the embossed portion is formed with a certain width, and includes a pattern in which a plurality of patterns and bands are gathered to a certain width. There is no restriction | limiting in particular about the width | variety and formation position of an embossed part.

  The “embossing” method is not particularly limited as long as the embossed pattern can be formed on the long wide ply. For example, rubber steel embossing using a rubber roll as the receiving roll may be used, or matched steel embossing using a concave embossing roll in which a concave embossing pattern complementary to the convex embossing pattern is engraved on the receiving roll may be used. . Examples of the “embossed” shape include a perfect circle, an ellipse, and a diamond shape.

  “Long and wide ply” means a ply that is an intermediate body of a tissue and that has a width and a length that are larger than a single tissue. Although the formation method of a long wide ply is not specifically limited, For example, it can form by the method as shown to FIG. 1B. In the method shown in FIG. 1B, base paper rolls 31a and 31b obtained by winding long and wide base papers 32a and 32b into a large-diameter roll are prepared, and base papers 32a and 32b are formed from the base paper rolls 31a and 31b. The base paper 32a and 32b are stacked by being fed in the direction and joined by the pressing rolls 33a and 33b to form a long wide ply 34A.

The “base paper” used for forming the ply is not particularly limited, but a base paper for tissue made to a basis weight of 10 to 18 g / m ² can be preferably used.

[1-2] Carving step:
The “cutting step” is a step of cutting the long wide ply on which the embossed portion is formed (that is, dividing in the width direction) into a plurality of long plies.

  Specifically, as in the cutting step 40 shown in FIGS. 1A and 1B, after forming the embossed portion 38B, a long length in which the embossed portion 38A is formed at a plurality of locations using a slitter 42 provided with a round blade 46. The wide ply 34A is cut along the edge on one side of each embossed portion 38A (cut line 43), has a width W2 corresponding to the tissue length L1, and has a strip-like edge along one edge E1. Embosses 48A are formed, and a plurality of sets of long plies 44A are formed on the other edge E2 without edge embossing. The slitter 42 is used for cutting the long wide ply 34A in combination with the anvil roll 41 as shown in FIG. 1B.

  There is no particular limitation on the position of cutting. Moreover, there is no restriction | limiting in particular also about the method of carving. For example, a method of cutting with a cutter equipped with a round blade or a band saw can be employed. As the cutter, a multi-blade saw, a round blade saw, a table-type multi-blade saw or the like can be suitably used.

[1-3] Cutting process:
The “cutting step” is a step of cutting a long ply to obtain a plurality of sets of tissue.

  Specifically, as in the cutting step 50 shown in FIG. 1A, the long ply 44A is cut to a length L2 corresponding to the tissue width W1 in the short direction perpendicular to the longitudinal direction. In this way, the ply 4A is formed by laminating a plurality of base papers 2a and 2b, and a band-shaped edge emboss 8A is formed along one end E3 of the ply 4A, and an edge is formed on the other end E4. It is possible to obtain a plurality of sets of tissue 1 in which no embossing is formed. This tissue 1 has a shape having a tissue length L1 and a tissue width W1.

  There is no particular limitation on the cutting method. For example, it can cut | judge using the cutter provided with the round blade or the band saw similarly to the cutting process.

[1-4] Tissue:
According to the above manufacturing method, as shown in FIGS. 5A and 5B, the ply 4A is formed by laminating a plurality of base papers 2a and 2b, and along the end E3 of the ply 4A, a band-shaped edge emboss is formed. The tissue 1 in which 8A is formed and the edge embossing is not formed at the end E4 facing the end E3 can be obtained.

[2] Tissue with cartons and manufacturing method thereof:
According to the method for manufacturing a tissue containing a carton of the present invention, the embossed portion forming step and the carving step are performed according to the method for manufacturing the tissue, and then the obtained long ply is folded to form a long tissue bundle. This is a method for producing a tissue bundle by cutting a length tissue bundle to obtain a tissue bundle and storing the tissue bundle in a tissue storage carton.

  The manufacturing method of the carton-containing tissue of the present invention includes five steps of an embossed part forming step, a cutting step, a folding step, a cutting step, and a boxing step as essential steps. However, since the embossed portion forming step and the cutting step can be performed according to the tissue manufacturing method, the description is omitted, and only the folding step, the cutting step, and the boxing step are described.

[2-1] Folding process:
The “folding step” is a step of folding a long ply obtained through the embossed portion forming step and the cutting step to form a long tissue bundle in which a plurality of sets of long plies are folded.

  Specifically, a plurality of sets of long plies are fed into a folding plate type processing machine, and the edge E1 of each long ply is oriented to one side in the stacking direction and the edge E2 is oriented to the other in the stacking direction. A set of long plies is folded back along the longitudinal direction, another set of long plies is sandwiched between the folded portions, and the other set of long plies is folded back along the longitudinal direction. A long tissue bundle is formed by folding a plurality of sets of long plies.

  As a method for folding the long ply, a method using a folded plate type processing machine (also referred to as “multiple machine”), a method using a rotary cylinder type processing machine (also referred to as “interfolder”), and the like. It has been known. However, in the manufacturing method of the present invention, a method using a folded plate type processing machine was adopted.

  The folded plate type processing machine is a processing machine provided with a long ply supply roll and a folded plate corresponding to the number of plies constituting the sanitary paper bundle. This processing machine repeats the operation of pulling out the long ply from the long ply supply roll, and folding the drawn long ply along the longitudinal direction with the folded plate, thereby folding a plurality of long plies. A long tissue bundle is formed. Therefore, the long tissue bundle can be formed so that the edge embossing formed along the longitudinal edge E1 of the long ply is oriented in one of the stacking directions.

  By orienting the edge embossing in one direction in the stacking direction in this way, when the tissue is stored in a carton, it is possible to manufacture a carton-containing tissue in which the edge embossing is located only at the end on the take-out side. In such a tissue, edge embossing is formed at an end portion on the tissue take-out side, so that ply peeling at the time of take-out of the tissue is prevented and the tissue can be easily taken out. In addition, the edge embossing improves the strength of the end portion on the take-out side, so that it is possible to effectively prevent the tearing of the tissue at the time of take-out.

  The folding pattern is not particularly limited. However, one set of long plies is folded back along the longitudinal direction, another set of long plies is sandwiched between the folded portions, and another set of long plies is folded back along the longitudinal direction. It is preferable to fold so as to have a repeated structure. With such a structure, when the uppermost ply is taken out of the carton, the ply located immediately below the ply can be taken out accordingly, so that the plies can be taken out sequentially.

  Examples of the “repetitive structure” include a double-fold repeated structure (C hold), a triple-fold repeated structure (Z-fold structure), or a repeated structure obtained by combining these.

  As an example of the two-fold repeated structure (C hold), as in the tissue bundle 20A shown in FIG. 6A, the plies 4C folded back in a V shape (C shape) as viewed from the side are alternately arranged so as to face each other. By being sandwiched, a repetitive structure in which a plurality of plies 4C are continuously folded can be exemplified.

  As an example of the three-fold repeated structure, as shown in a tissue bundle 20B shown in FIG. 6B, a plurality of plies 4D are formed by alternately sandwiching the plies 4D folded back in a Z shape as viewed from the side so as to face each other. Can be mentioned a repetitive structure in which is continuously folded.

  As a repeating structure combining these, as shown in a tissue bundle 20C shown in FIG. 6C, a ply 4C folded back into a V shape (C shape) and a ply 4D folded back into a Z shape are seen alternately. By being sandwiched between the plurality of plies 4C and 4D, a repeated structure in which the plurality of plies 4C and 4D are continuously folded can be exemplified.

  In the tissue bundles 20A to 20C shown in FIGS. 6A to 6C, the edge embosses 8C and 8D formed on the tissue end E3 side are all oriented upward in the tissue stacking direction (that is, the edge embosses 8C and 8D). Is an example in which the plies 4C and 4D are folded on the upper surface side of the carton.

[2-2] Cutting process:
The “cutting step” is a step of cutting the long tissue bundle obtained in the folding step in a direction (short direction) perpendicular to the longitudinal direction.

  Specifically, a long tissue bundle is made of a ply in which a plurality of base papers are laminated by cutting a long tissue bundle into a length corresponding to the tissue width in a short direction perpendicular to the longitudinal direction. A strip-shaped edge emboss is formed along the end E3 of the sash, and a tissue bundle is obtained in which the tissue having no edge emboss is folded on the end E4 facing the end E3. By doing so, it is possible to obtain a plurality of tissue bundles at a time in which tissue having a predetermined tissue length and tissue width is folded.

  As the cutting method, the same method as the tissue manufacturing method described above can be adopted. For example, it can cut using a cutter provided with a round blade or a band saw.

[2-3] Box packing process:
The “boxing step” is a step of storing the tissue bundle obtained in the cutting step in a tissue storing carton and packing it.

  Specifically, the tissue bundle is formed such that the tissue end E3 (the end on the side where the edge embossing is formed) is on the upper surface side of the carton, and the tissue end E4 (the end on which the edge embossing is not formed). The tissue is stored inside the carton for storing the tissue so that the portion is oriented toward the bottom side of the carton to obtain a tissue containing the carton.

  The boxing method for tissue bundles can employ a wide range of conventionally known boxing methods, and is not particularly limited. For example, as shown in FIG. 7, an upper space 62, a bottom surface 64, and a pair of side surfaces 66 are formed, and an internal space defined by these surfaces is formed, and each of the top surface 62, the bottom surface 64, and the pair of side surfaces 66 is formed. A rectangular tubular carton 60 with a flap 68 extending from the end edge to form a wife surface is prepared, the tissue bundle 20 is stored in the internal space of the rectangular tubular carton 60, and then the flap 68 is bent. The method of storing can be taken by forming the wife face by fixing.

  Note that the “square tubular carton” can be formed by bending a carton blank made of a paper material or the like such as the carton blank 80 shown in FIG.

  The carton blank 80 has a top surface 62, a bottom surface 64, and a pair of side surfaces 66 formed of a sheet of paper through a fold line, and an inner flap 68b is formed from the edge of the side surface 66 through the fold line. It has been extended. Further, an upper outer flap 68a extends from the edge of the upper surface 62 via a folding line. Similarly, an outer bottom flap 68c extends from the edge of the bottom surface 64 via a folding curve. Has been issued. Further, a side joining margin 82 extends from one side edge portion of the bottom surface 64 via a folding line.

  The carton blank 80 has an annular outlet forming cut line 72 formed on a surface corresponding to the upper surface of the carton. And the window film 70 in which the slit 74 was formed is affixed on the position which surrounds the cut-out line 72 for outlet formation. Such a carton blank 80 can be formed into a rectangular tubular carton in which both end faces are opened by bending each folding line and joining the side joint allowance 82 and the side face 66.

  In the carton blank 80, a pair of U-shaped push-up piece forming cut lines 84 is formed at the center of the surface to be the bottom surface 64. When this push-up piece forming cut line 84 is pressed and broken and bent inside the carton, the tissue inside the carton is pushed up to the upper surface side by the push-up piece. Therefore, it is possible to stably pop up the tissue from the upper surface outlet to the last one.

[2-4] Tissue with cartons:
According to the manufacturing method, the carton-containing tissue of the present invention can be obtained. The tissue containing cartons according to the present invention includes a tissue bundle in which a plurality of sets of tissue are folded, and a carton for storing a tissue bundle in which a cut-out line for forming a tissue outlet is formed on the upper surface. Is provided.

  The tissue to be stored is composed of a ply in which a plurality of base papers are laminated, edge embossing is formed along one end E3 of the ply, and edge embossing is not formed on the other end E4. is there.

  The tissue bundle formed by the tissue is formed by folding a plurality of sets of tissue so that the end E3 of the tissue is oriented in one of the stacking directions and the end E4 of the tissue is oriented in the other of the stacking directions. is there.

  The tissue bundle is housed in the carton so that the tissue end E3 is oriented on the top surface side of the carton and the tissue end E4 is oriented on the bottom surface side of the carton.

  The method for producing a tissue and the method for producing a carton-containing tissue of the present invention can be suitably used for the production of a tissue having edge embossing for preventing ply peeling, particularly, a carton-containing tissue.
