Description

Sanitary tissue paper products

  The present invention relates to a sanitary thin paper product formed by packaging a bundle of a plurality of folded sanitary thin papers.

A sanitary thin paper product in which a plurality of sanitary thin paper sheets are folded and bundles stacked in such a way that the folded pieces overlap are stored in the packaging body, and are sequentially taken out from the outlet formed on the upper surface of the packaging body when in use. Well known. For example, it is represented by tissue paper products.
In this type of product, when one sheet of sanitary thin paper is taken out from the take-out port, a bundle is formed such that a part of the other adjacent laminated sheet is exposed from the take-out port (this Such a method is also called a pop-up type).
In producing such a bundle of sanitary thin paper, PCMC (Paper Converting Machine Company) based on the technology described in US Pat. No. 4,052,048 (Japanese Patent Publication No. 55-1215: Prior Art Document 1). ) Continuous folder folding equipment interfolder is widely used in the industry.
This interfolder is also called a PCMC system facility or a multi-stand interfolder, and can manufacture a bundle of sanitary thin paper at an extremely high speed. (Hereinafter, in the description, it is also simply called an interfolder.)
This interfolder has a folding plate machine group in which a plurality of folding plate machines are arranged in the flow direction (also referred to as a line direction), and an original fabric roll support portion is provided for each of the descending plate machines. . An original roll is set on each original roll support, and a continuous sheet is fed out simultaneously from each original roll and supplied to a corresponding folding machine. The folding plate machine group folds the continuous sheets from the respective rolls in the direction (also referred to as the width direction) perpendicular to the continuous direction, and is continuously folded by other folding plate machines positioned forward and backward in the flow direction. A bundle of sheets of continuous sanitary thin paper having a number corresponding to the number of folding plate machines that are stacked alternately with the sheets and moved at the most downstream position is formed.
In order to obtain a sanitary thin paper product, a continuous sanitary thin paper bundle is cut into an appropriate length and stored in a package having an outlet on the upper surface.

  By the way, some sanitary thin paper products are known in which patterns are printed on sanitary thin paper. Such products are excellent in design and the like, and have high customer suction.

However, this pattern printing is not widely used in pop-up products.
In pop-up type products, bundles are generally manufactured by an interfolder as described above, and after being fed out from the raw roll support, printing is performed and supplied to the folded plate, or printing is performed once. If the roll is then set on the roll roll support and supplied to the folded plate, the ink that forms the pattern will adhere to each part of the folding machine and contaminate the equipment, or troubles during high-speed operation. This is because it is easy to generate.

A high-value-added product containing sanitary thin paper having the properties is provided.

Next, embodiments of the present invention will be described in detail below with reference to the drawings.
"Sanitary tissue paper products"
According to the present invention, a bundle of sanitary thin paper sheets obtained by folding and laminating a plurality of sanitary thin paper sheets is housed in a packaging body having an outlet or an outlet forming portion formed on the upper surface, and the sanitary thin paper is used from the outlet when used. This is a sanitary thin paper product that is configured such that when one sheet is taken out, a part of the adjacent lower layer sheet is exposed from the outlet.

[Structure of sanitary thin paper]
The sanitary thin paper V1 according to the present invention has a rectangular shape as shown in FIG. 1, and has a ply structure in which a plurality of thin papers 1 and 2 having the same shape are laminated. The number of thin paper sheets (the number of plies) to be laminated is not particularly limited, and may be appropriately changed to, for example, 2 sheets (2 plies), 3 sheets (3 plies), 4 sheets (4 plies), or more. can do. In particular, two or three sheets are desirable because the effect is remarkable.

In the following, a particularly preferable example of a two-ply structure in which two thin papers are stacked will be mainly described. However, the present invention is not limited to this number and structure.
[Hygienic thin paper]
In the sanitary thin paper product V1 according to the present invention, the one on which the pattern P is printed is essential, and one on which the pattern is not printed can also be used. Since these differences are only with or without pattern printing, the sanitary thin paper on which the pattern P is printed will be mainly described here. Those having no pattern P will be understood from the following description.
The sanitary thin paper V1 having the pattern P according to the present invention is an element characterizing the product of the present invention. The sanitary thin paper V1 has a pattern printed on the inner surface of one of the two thin papers located on the outermost layer of the laminated thin papers 1 and 2.

In this embodiment, since there are two plies, a pattern is printed on the inner surface of one of the two thin papers laminated.
(Here, in the present invention and the present specification, the laminated inner surface means a portion facing the other thin paper among the surfaces of the thin paper constituting the ply structure, and the sanitary thin paper itself not facing the other thin paper) The outer surface of is also called a laminated outer surface.)

  In the sanitary thin paper V1, since the pattern P is formed at the above position, the pattern P passes through the thin paper 1 itself on which the pattern P is printed or the other thin paper 2 laminated thereon. Recognized from the outside. Therefore, compared to conventional sanitary thin paper with a pattern directly applied to the outer surface by ink, etc., the edges of the pattern and design constituting the pattern are perceived with moderate blurring, and a watermark pattern It exhibits an unprecedented design that evokes a light, soft impression like a blurry pattern.

  In the sanitary thin paper V1 of this embodiment, the applied pattern P is formed by drawing a predetermined pattern or design with colored ink or the like. This can be formed, for example, by known printing techniques for thin paper. Specific examples include gravure printing and flexographic printing.

  In addition, the specific design that forms the pattern P, the formation range, size, shape, etc. of the design are not particularly limited, and appropriate designs such as logo marks, numbers, characters, geometric patterns, and appropriate sizes Can be selected. In the example of illustration, it is a pattern which consists of a flower figure.

On the other hand, the colored portion of the design or design constituting the pattern P should be clearly different from the background color of the thin paper. As the ink used for forming the pattern P, a known ink used for printing on thin paper such as toilet paper and tissue paper can be used regardless of dye ink or pigment ink. If a pattern is formed by printing with these inks, a design different from the ground color can be given.
Although not limited, it is desirable that the difference ΔL * in the L * value in the L * a * b * color system between the colored portion and the ground portion M is 3.0 or more. The L * value can be measured using, for example, a measuring device “PF-10” manufactured by Nippon Denshoku Industries Co., Ltd.

  The thin papers 1 and 2 should have an opacity of 30 to 55%, preferably 35 to 45% based on JIS P 8149 so that the applied pattern can be clearly seen. With this degree of opacity, the pattern (design) can be seen through from the outside, and the pattern imparted thereto can be easily recognized.

Here, it is desirable that the printed surface of the thin paper 1 is printed on the back surface of the thin paper 1. The front and back referred to here are the front and back of paper generally distinguished in the industry. If it demonstrates, the surface which was in contact with the papermaking net | network in a manufacturing process will be the surface which was not contacting back. As for the front and back of paper, the surface has better surface characteristics. Therefore, there is an advantage that it is excellent in touch and smoothness, or that it is easier to express smoothness than the back surface.
Therefore, the sanitary thin paper of the present invention is positioned so that the back surface is the inner surface and the front surface is the outer surface of the thin paper that constitutes the outer surface of the sanitary thin paper. The pattern is preferably printed.

[Thin paper]
On the other hand, the thin papers 1 and 2 constituting the sanitary thin paper V1 according to the present invention are made of pulp without distinction between non-printed and printed ones, and the raw material pulp is not particularly limited. An appropriate raw material pulp can be selected according to the specific use of the sanitary thin paper, and can be used by appropriately blending.

  Examples of raw material pulp include wood pulp, non-wood pulp, synthetic pulp, waste paper pulp, and more specifically, groundwood pulp (GP), stone grand pulp (SGP), refiner ground pulp (RGP), pressure type Mechanical pulp (MP), chemical mechanical pulp (CGP), semi-chemical pulp (such as ground pulp (PGW), thermomechanical pulp (TMP), chemithermomechanical pulp (CTMP), bleach chemithermomechanical pulp (BCTMP)) Chemical pulp (SCP), kraft pulp (KP) such as hardwood bleached kraft pulp (LBKP), softwood bleached kraft pulp (NBKP), soda pulp (AP), sulfite pulp (SP), dissolved pulp (DP), etc. CP), nylon, rayon, polyester, polyvinyl alcohol ( VA) and other raw paper pulp such as synthetic pulp, deinked pulp (DIP) and waist pulp (WP), waste pulp (TP), cotton, flax, hemp, jute, manila hemp and ramie One or several kinds of pulp, straw pulp, esparto pulp, bagasse pulp, bamboo pulp, kenaf pulp, and other auxiliary pulps such as bast pulp can be appropriately selected and used.

  In particular, the raw material pulp is preferably a blend of NBKP and LBKP. Waste paper pulp may be blended as appropriate, but in terms of texture and the like, it is preferably composed only of NBKP and LBKP. In this case, the blending ratio is NBKP: LBKP = 10: 90 to 50:50. In particular, NBKP: LBKP = 40: 60 is particularly desirable.

  The raw material such as raw material pulp is made into thin paper through, for example, a known papermaking process, specifically, a wire part, a press part, a dryer part, a size press, a calendar part, and the like. When making paper, for example, a suitable agent such as a pH adjuster such as a dispersant, caustic soda, or aqueous ammonia, an antifoaming agent, an antiseptic, a fluorescent dye, a mold release agent, a water-resistant agent, a flow modifier, and a yield improver. Can be added.

On the other hand, the thin paper is not limited to white, and may be light pink or blue, for example, in order to obtain an effect of clearly showing the pattern, or an effect of making the overall appearance look high-class. The thing of the color of the pulp itself which is not colored may appear.
The adjustment of the ground color of the thin paper itself can be achieved by a known technique such as making paper using a papermaking material colored according to the technique.

[Basis weight / paper thickness]
If on the other hand, the basis weight of the sanitary thin paper V1 according to the present invention, can be appropriately adjusted, preferably, 20 to 80 g / m ² as a whole ply, preferably 26~40g / m ^2, a stacked structure 10 to 40 g / m ² per layer (each ply). Preferably it is 12-20 g / m < ² >. If it is less than 10 g / m ² , it is preferable from the viewpoint of improving softness, but it is difficult to ensure adequate strength that can withstand use, and if it exceeds 40 g / m ² , it becomes too hard and soft to the touch. Tends to be bad. This range is particularly suitable when tissue paper is used for sanitary thin paper. In addition, the US tsubo is based on the JIS P 8124 US tsubo measurement method.

The paper thickness can also be adjusted as appropriate. In the case of tissue paper, the thickness is preferably 60 to 250 μm. The paper thickness is less than 60 [mu] m, although preferred in view of softness improvements, it is difficult in that to properly secure the strength of the tissue paper. On the other hand, if it exceeds 250 μm, the texture of the tissue paper is deteriorated and a feeling of tingling is generated during use. In addition, when it is set as a laminated structure, it is not necessary to unify all the paper thickness of the base paper sheet which comprises each layer.

  As a measuring method of the paper thickness, it shall be measured using a dial thickness gauge (thickness measuring instrument) “PEACOCK G type” (manufactured by Ozaki Seisakusho) under the conditions of JIS P8111. Specifically, confirm that there is no dust, dust, etc. between the plunger and the measuring table, lower the plunger on the measuring table, move the memory of the dial thickness gauge to adjust the zero point, and then Then, raise the plunger and place a sample (eg, toilet paper) on the test table, slowly lower the plunger and read the gauge at that time. At this time, only the plunger is placed. The paper thickness is an average value obtained by performing measurement 10 times.

[Bundle of sanitary thin paper]
The bundle of sanitary thin papers W1 of the present invention is formed by folding and laminating the above-described sanitary thin papers. More specifically, as shown in FIG. 2, the rectangular thin papers are substantially folded in two so that the edges e of the folded pieces are located on the folded inner surface of the adjacent thin papers, and are alternately overlapped. Are stacked. Here, the term “substantially” means that a slight fold of the edge formed in manufacturing is allowed.

  In the bundle W1 of sanitary thin paper with the present laminated structure, when one folded piece 10 located at the uppermost position is pulled up, the other folded piece 11 adjacent immediately below it is pulled upward and lifted. Accordingly, when the bundle W1 of sanitary thin paper having such a structure is stored with the uppermost surface facing the upper surface of a package having an outlet or the like on the upper surface described later, the first sheet (the most When one sheet positioned on the upper surface is pulled out, a part of the other sheet positioned below it is exposed.

[Configuration example 1 of a bundle of sanitary thin paper]
On the other hand, the bundle of sanitary thin paper of the present invention includes a sanitary thin paper having a specific structure in which a pattern is printed on the inner surface of the laminate.
Of course, all of them may be composed of sanitary thin paper V1 having a specific structure on which a pattern is printed.
In this case, a plurality of types of sanitary thin papers V1 having different patterns can be appropriately stacked at random. How many kinds of patterns are prepared is an appropriate design matter. The patterns of all the sanitary thin papers V1 constituting the bundle may be different, or for example, about 2 to 10 types may be prepared and stacked randomly.
If the bundles of sanitary thin papers V1 with different patterns are randomly stacked, when one sheet is taken out from the take-out port, the other pattern of the lower layer that is exposed to follow cannot be predicted. It becomes a product that does not come.

  Moreover, if it is set as the sanitary thin paper V1 in which all the patterns were printed, the sanitary thin paper may be laminated so that the patterns are different for each appropriate lamination. That is, as shown in FIG. 2, a predetermined number (for example, 10) from the uppermost surface is composed of sanitary thin paper having a pattern A, and the lower 10 sheets are composed of sanitary thin paper having a pattern B. Similarly, A sanitary thin paper having a pattern C and a pattern D can be sequentially laminated on the lower layer.

  Also, for example, as shown in FIG. 3, only the position corresponding to the appropriate number of layers, for example, the position of the stack corresponding to the number of joints such as the 10th sheet and the 20th sheet from the top (position A in FIG. 3). As the patterns having different patterns, the other sanitary thin papers (region B in FIG. 3) can be made the same pattern.

A product obtained by storing a bundle of sanitary thin papers configured as described above in a package can generally understand the number of sanitary thin papers contained when the sanitary thin papers having different patterns are taken out.
Therefore, if a sanitary thin paper having a different pattern is positioned only at a position corresponding to an appropriate number of layers, the pattern P is positively used as a pattern P in which the remaining number, the number of uses, etc. are expressed as letters / numerals. It is also possible to understand the number of sheets and the remaining number.

[Configuration example 2 of a bundle of sanitary thin paper]
On the other hand, the bundle of sanitary thin paper of the present invention does not necessarily need to be composed of the characteristic sanitary thin paper having the pattern printed thereon. Sanitary thin paper on which a pattern is not printed may be mixed.
In this case, a sanitary thin paper having a pattern and a sanitary thin paper having no pattern can be appropriately laminated at random. How many kinds of patterns are prepared, and how much the ratio of sanitary thin paper having a pattern to sanitary thin paper having no pattern is appropriate design matters. About the sanitary thin paper which has a pattern, all patterns may be made different, for example, about 2-10 types may be prepared and they may be laminated | stacked at random.
In a product using such a bundle, when one sheet is taken out from the outlet, it cannot be predicted whether or not the other sheet that is exposed following the pattern has a pattern.

Also, for example, as shown in FIG. 4, only the position corresponding to the appropriate number of stacks, for example, the stack position corresponding to the number of joints such as the 10th sheet and the 20th sheet (position a in FIG. 4). As the sanitary thin paper having a pattern, other sanitary thin paper (symbol b in FIG. 4) can be a similar patternless sanitary thin paper. Moreover, it can be configured in reverse. The bundle of sanitary thin papers configured as described above can generally understand the number of sanitary thin papers contained when the sanitary thin paper having a pattern is taken out.
Therefore, if a sanitary thin paper having a pattern only at a position corresponding to an appropriate number of layers is positioned, the pattern P is positively used as a pattern P formed by printing the remaining number or the number of use as characters. The number of sheets and the remaining number can be understood.

[Packaging example 1]
As the package X1 bundles of sanitary thin paper is accommodated, it is preferably employed box body of rectangular parallelepiped shape, also called cartons. As shown in FIGS. 5 and 6, the carton X1 includes a paper box 20 having an annular perforation line 21 that is an outlet forming portion on the upper surface, and a resin that covers a range 21a surrounded by the perforation line 21 from the inside of the paper box. And made film 22.

The paper box 20 is a paper box that forms the outer shape of the carton X1, and the configuration of the known carton paper box can be adopted for the size, shape, developed shape, and the like.
As the shape, a hexahedron shape having a rectangular upper surface 20U constituted by a pair of parallel long edges 20L, 20L in the illustrated example and a pair of parallel short edges 20S, 20S shorter than these can be exemplified, The structure includes an upper surface, a bottom surface and side surfaces connecting these, and a bottom surface side end surface piece, a side surface end surface piece, and an upper surface side end surface piece connected to both side edges in the longitudinal direction of each surface. An example is a structure in which after folding back to the inner surface side of the box, the upper surface side end surface piece and the bottom surface side end surface piece are folded on top of each other and the contact portion of each piece is adhered by a hot melt adhesive or the like.

The size of the carton X1 is slightly larger than the bundle of sanitary thin paper, and is generally an inner shape that is approximately 1 to 20 mm larger than the outer shape of the bundle. When the size of a general carton is illustrated, the longitudinal edge is generally about 110 to 320 mm, the short edge is about 70 to 200 mm, and the height is about 40 to 150 mm. At least in the present invention, a carton of this size can be used.
As a material of the paper box 20, for example, a known paper material mainly using various pulps such as virgin pulp and waste paper pulp can be adopted. Preferably, the material of the paper box is coated cardboard with a basis weight of 250 to 500 g / m ² , preferably 350 to 400 g / m ² .

  Although not shown, the paper box 20 is a single piece of appropriate characters, figures, pictures, symbols, such as floral patterns, spiral patterns, wave patterns, dot patterns, turtle shell patterns, star patterns, cross patterns, geometric patterns, or the like. An appropriate pattern constituted by a combination can be adopted. The pattern can be applied to the outer surface of the paper box by a known printing method such as gravure printing.

  On the other hand, the perforation line 21 formed on the upper surface 20U of the paper box 20 has an annular shape, is formed by a known method and a cut tie ratio, and the specific shape of the range 21a surrounded by this is not necessarily limited. However, in the carton X1, as in the illustrated example, a substantially elliptical shape or a rectangle having a long side in the direction along the longitudinal direction of the paper box upper surface 20U is representative, and the takeout and convenience are high. This shape, which can be produced on many existing production lines, is preferred.

On the other hand, the resin film 22 is larger than the size of the range 21a surrounded by the perforation line 21, and is, for example, a rectangle or an ellipse, and particularly affects the peeling of the annular perforation line 21 on the inner surface side of the upper surface of the paper box 1. It is adhered outside the annular perforation line 21 so that there is no.
A suitable material for the resinous film 22 is a polyethylene film, but examples thereof include polypropylene and polyester.
The thickness of the resin film 22 is suitably 10 to 200 μm. If it is less than 10 μm, the strength is insufficient, and the probability of tearing or breaking when taking out the sanitary thin paper increases. On the contrary, if it exceeds 200 μm, there is no problem of strength, but it becomes difficult to take out and the cost is increased.

On the other hand, a slit 23 is formed in the resin film 22, and the slit 23 is located in a range 21a surrounded by a perforation line.
Therefore, as shown in FIGS. 5 and 6, by cutting off the range 21a surrounded by the perforation line 21 along the annular perforation line 21, an outlet 25 is formed on the upper surface 20U of the paper box, and the resin film 22 and the slit 23 formed in it are exposed through the outlet 25. In addition, the length of the said slit 23 can be made into an appropriate length, and the length considered suitable with respect to the magnitude | size relationship with a known cyclic perforation line is employable.
The sanitary thin paper stored as a bundle in the package is taken out one by one from the take-out opening 25 through the slit 23.

[Packaging example 2]
On the other hand, when a package other than the carton of the present invention is exemplified, for example, a package made of an exterior film can be mentioned. Although not illustrated, this package is achieved by known film packaging called, for example, pillow packaging, gusset packaging, caramel packaging, or the like.
The packaging method for configuring these packages is a well-known technique, but more specifically, pillow packaging wraps a bundle to be packaged with an exterior film, and the winding direction thereof. It is the packaging mode formed by adhering the overlapping edges and further adhering the part extending beyond the package. A known device is used as the device for performing the pillow wrapping.

  Caramel packaging wraps a bundle to be packaged with an exterior film, bonds the overlapping edges in the winding direction, and further extends the part extending beyond the package from two opposing edges. It is a packaging mode formed by folding at least the front edge portions of the triangular piece or the trapezoidal piece formed at that time on the packaged object side. A known apparatus is used as the apparatus for performing the caramel wrapping.

  The gusset packaging is a packaging mode in which an article to be packaged is inserted into a cylindrical body having openings at both ends, both ends protruding beyond the article to be packaged are used as surplus, and the opening where the surplus is bonded is sealed. A known device is also used as the device for performing such gusset packaging.

It is made by heat fusion, ultrasonic fusion, hot melt adhesive, etc. for each part of the exterior film.
In the packaging body by an exterior film, a perforation line, a slit line, etc. are provided in the position used as the upper surface of an exterior film previously, and it is set as an extraction port or an extraction port formation part. It is good also as an outlet structure which provides a cyclic | annular opening in the position used as an upper surface, and seals the opening with a cover film so that peeling is possible further. In any case, pop-up products and film packaging can be used.

  Specific examples of the exterior film 11 include polyethylene films such as HDPE (high density polyethylene) film, LDPE (low density polyethylene) film, LLDPE (linear low density polyethylene) film, polystyrene film, polypropylene film, etc., or a laminate thereof. A film is mentioned. HDPE films, LDPE films, HDPE and LDPE blended films are preferred because they are inexpensive, have appropriate tearability, and can ensure adequate strength. Moreover, the laminated film by which the paper layer and the nonwoven fabric layer were laminated | stacked with respect to these resin films may be sufficient.

  The manufacturing method of the exterior film to be used is not limited. What is necessary is just to manufacture with an appropriate film formation method according to the kind of resin used as the raw material of an exterior film. For example, an extrusion method such as a T-die method may be mentioned. In the case of a laminated structure, an extrusion laminating method or the like can be given. Moreover, you may perform the extending | stretching process for making it easy to tear to a predetermined direction.

Although the thickness of an exterior film is not specifically limited, It is good that it is at least 10 micrometers or more. If the thickness is less than 10 μm, the strength is insufficient and the possibility of unintentional breakage increases.
In addition, regarding the package according to the present invention, an appropriate package such as a plastic case can be adopted as long as the pop-up type is not hindered.

"Manufacturing method of sanitary thin paper products"
Subsequently, the manufacturing method of the sanitary thin paper product concerning the above-mentioned this invention is explained in full detail.
[Secondary film roll forming process]
In the manufacturing method according to the present invention , as shown in FIG. 7, first, continuous sheets 31 and 31 are fed out from a plurality of one-ply original fabric rolls 30 and 30, and each continuous roll is passed through an appropriate support roll and nip roll R. The sheets are stacked and stacked, and then wound up to obtain a secondary raw roll 40. In the illustrated example, a two-ply secondary material roll forming step is illustrated.
At this time, in the case of two plies, (1) the layers are laminated so that each back side of each thin paper is the outer surface (hereinafter referred to as back and back lamination), or (2) one surface and the other It is desirable to laminate (hereinafter referred to as front and back lamination) so that the back surface of the substrate faces. In addition, the front and back here mean the front and back of the above-mentioned paper.

On the other hand, when two or more plies are used, it is preferable that another continuous thin paper is laminated on one outer surface of the back and back laminate and the front and back laminate. Note that. When adopting front and back lamination, it laminates on the surface side.
Here, the continuous sheet which comprises the said original fabric rolls 30 and 30 is a strip | belt-shaped thin paper, The composition and physical property are the same as the composition and physical property of the above-mentioned thin paper.

[Printing process]
Next, if the secondary web roll is formed, as shown in FIG. 8, the secondary continuous sheet 41 is unwound from the secondary web roll 40 and sequentially fed out, while one side of the outer surface of the secondary continuous sheet 41 is drawn. A pattern P is printed by the printing machine 50.
At this time, when printing is performed on a secondary continuous sheet having a laminated structure including the back and back laminate and the front and back laminate, it is desirable to print on the back side.
For printing, known printing techniques such as flexographic printing and gravure printing can be employed. The printing machine of the illustrated example is a flexographic printing machine that can be preferably employed. In this case, the printing plate roll 51 and the number of lines are 40 to 100 lines, halftone dots 0.1 to 99%, preferably about 15 to 50%. It is desirable to print with a specification of 250 or more anilox rolls 52.

The pattern P has been described in the section of the sanitary thin paper, but is not particularly limited in the present invention. There are no particular restrictions on the specific design or design range, size, shape, etc. that make up the pattern, and it is possible to select an appropriate size, such as a logo mark, numbers, characters, geometric patterns, etc. it can.
Preferably, the area occupation ratio of the symbol is 10 to 50% of the whole. Contrast with the pattern of the ground part becomes clear.
The printing ink is not particularly limited in the present invention. Regardless of dye ink or pigment ink, known inks used for printing on thin paper such as toilet paper and tissue paper or sanitary thin paper can be used. What is necessary is just to adjust a viscosity etc. suitably.

  Here, in order to make sanitary thin paper with higher added value, a fragrance may be contained in the printing ink to produce an aromatic sanitary thin paper. As for the fragrance, known fragrances used in toilet paper, tissue paper and the like can be used.

[Secondary printing roll forming process]
After the printing on the secondary continuous sheet 41, as shown in FIG. 8, the secondary continuous sheet is taken up again to form a printed secondary web roll 45. Printing and rewinding can be performed continuously.
When performing the rewinding operation again, in a case other than the two-ply back and back lamination, the surface on which the printing is performed becomes the winding outer surface (the surface constituting the outer peripheral surface when a roll is used). It is desirable to wind it up.

[Reversal process]
If the secondary continuous sheet 41 is wound up after printing, then, as shown in FIG. 9, a reversing step is performed which is one of the features in the manufacturing method of the present invention.
As shown in FIGS. 9A to 9C, this step is performed on the outer surface side in a wound state in the secondary continuous sheet 41 having a laminated structure constituting the printing secondary raw roll 45. Only the outermost continuous sheet 41 </ b> A located at the center is peeled from the other continuous sheet 41 </ b> B and unwound around one turn so as to be reversed so that the outermost surface K becomes the laminated inner surface. By this operation, the printed surface becomes the laminated inner surface.

Here, in the above description, an example in which the printing secondary raw roll is a two-ply back and back lamination, printing is performed on the back side with a two-ply front and back lamination, and winding is performed so that the printed surface becomes the winding outer surface. Example of printing secondary web roll, 3 layers or more laminated structure including back and back lamination, front and back lamination, printing on the back side and winding and printing so that the printed surface becomes the winding outer surface In the example of the secondary raw roll, it is preferable that when the operation of inverting the continuous sheet of the outermost layer in this step is performed, the surface of the paper having excellent surface characteristics becomes the outer surface side, and the printing surface This is because is positioned on the inner surface of the laminate. That is, it is possible to obtain a product having an advantage due to the characteristics of the front and back surfaces of the paper.
In the present invention, in view of performing this inversion process, it is desirable that ply bonding of the continuous laminated sheet is not performed in the previous stage, or even if it is performed, the pressure is extremely low.

[Continuous thin paper bundle forming process]
Next, as can be understood from FIGS. 10 and 11, the printed secondary web roll 45 ′ in which the outermost continuous sheet 41 </ b> A is inverted is cut as it is or with an appropriate width, and is aligned in the flow direction. The original fabric roll support portion 70 of the interfolder M, which includes a plurality of folding plate machines 70, 70 ... and original fabric roll support portions 71, 71 ... provided corresponding to the respective folding plate machines 70, 70 ... Set to 70 ... In addition, FIG. 10 is the figure which looked at the folding machine from the flow direction front, and the several folding machine is arranged in the direction which penetrates a paper surface. Further, reference numerals G1 to G3 in the figure are guide rollers, and reference numeral 77 is a conveying device that forms a line of continuous sanitary thin paper.
In addition, although roll 45 'which performed the inversion process is set to the original fabric roll support part 71 here, after setting the roll 45 to the original fabric roll support part 71, you may perform an inversion process.

Next, the secondary continuous sheet 49 that is sequentially reversed from the original fabric roll support portion 71 is fed out, and the secondary continuous sheet 49 is folded and stacked by the folding plate machine 70 to form a bundle W of continuous sanitary thin paper.
Here, the interfolder M according to the present invention is a well-known and well-known one. However, as will be described, a large number (for example, 101) according to the number of sheets stored in the package as shown in the figure. ), A plurality of folding plate machines 70, 70... Installed at intervals in the flow direction, and original roll support portions 71, 71... Provided corresponding to the respective folding plate machines 70, 70. In the predetermined folding plate machine 70, the side portion of the continuous sheet fed from the corresponding original roll support portion 71 is related to the continuous sheet wrapped from the front and rear folding plate machines in a substantially C shape. It is configured to be folded.
Therefore, in this interfolder, the continuous sheets 49, 49... From the respective folding plate machines 70, 70... Are sequentially stacked in order from the upstream to the downstream in the flow direction, and from the folding plate machine located at the most downstream in the flow direction. The continuous sanitary thin paper bundle is formed so that the continuous sheet is positioned on the uppermost surface.

In the example of the manufacturing method according to the present invention, the outermost continuous sheet 41 </ b> A is peeled once in the reversing step. Therefore, it is preferable to perform ply embossing on the continuous sheet fed from the raw roll support.

  For example, although not shown in the figure, the ply embossing is provided with a pair of ply embossing rollers composed of a metal roll and a rubber roll having an embossed convex part on the surface immediately after the raw roll support part. This can be done by passing the side edge of the continuous sheet. The specific embossing pressure in the ply embossing may be appropriately determined in consideration of the operation speed of the interfolder.

Here, as understood from the description of the interfolder M, the configuration of the bundle W1 shown in [Configuration Example 1 of Sanitary Thin Paper Bundle] and [Configuration Example 2 of Sanitary Thin Paper Bundle] of the present invention described above is It is determined according to the mode of the setting of the secondary web rolls for the respective web roll support portions 71 and 71 in the folder M.
That is, when forming the bundle W1 of sanitary thin papers having all the patterns, the printing secondary original roll 45 'on which the pattern P is printed is set on all the original roll support parts 71 in the interfolder. If a bundle including non-printing sanitary thin paper is appropriately formed, a non-printing secondary original roll is set on an appropriate original roll support.

  And in the case of forming a sanitary thin paper bundle W1 composed of only the sanitary thin paper V1 having the pattern P, or in the case of forming a sanitary thin paper bundle interposing a non-pattern sanitary thin paper, These secondary rolls are set at random on each roll roll support 71.

  In addition, when a bundle of sanitary thin papers having different patterns for each predetermined lamination shown in FIG. 2 is formed, the folding plate machines 70 are grouped into a predetermined number from the upstream side or the downstream side in the flow direction, The secondary printing roll with the same pattern P is set only within the group.

  In addition, when forming a bundle of sanitary thin papers having different patterns only at the stacking positions corresponding to the number of nodes, such as the 10th sheet and the 20th sheet, from the upper surface side, as shown in FIG. Folding plate machine 70 at a predetermined position from the side, for example, the 10th and 20th machine from the upstream side or the downstream side, and the original roll support corresponding to the folding plate machine 70 at the position corresponding to the appropriate number of layers A continuous printing secondary original sheet 45 ′ having a different pattern is set only in the portion 71, and a continuous printing secondary original sheet 45 ′ having the same pattern different from the above pattern is set in all other raw roll support portions. To do.

  Furthermore, in the case of forming the bundle W1 having sanitary thin paper having a pattern only at the stacking position corresponding to the number of the knots such as the 10th sheet and the 20th sheet from the upper surface side as shown in FIG. A printed secondary original roll 45 ′ having a pattern printed thereon is set only on the roll support part 71, and a non-printed secondary original roll is set on the other original roll support part 71.

  If the pattern is different only in the position of a joint or has a pattern, in the printing process described above, a character string or number that can understand the number of joints or the number of layers is printed as a pattern. Thus, an effective remaining amount display function and used number notation function are provided.

[Storage process]
On the other hand, once the desired continuous sanitary thin paper bundle W is formed in the interfolder, the continuous sanitary thin paper bundle W is then cut into an appropriate length and stored in a package as a sanitary thin paper bundle W1. A conventionally known method can be used as a method for storing in the package.
