Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a tissue roll and a method for manufacturing the same,

The present invention relates to a method for producing a secondary fabric roll for a tissue paper product supplied to a multi-stand type folder and a method for producing a tissue paper product.

A box-packed product of a tissue paper is generally produced by folding a plurality of successive tissue papers by an interfolder (folding facility), stacking them together and cutting them into a predetermined length to obtain a tissue paper bundle, and placing the tissue paper bundle in a storage box .

Examples of such an interfolder include a multi-stand type (multi-type) interfolder as disclosed in the following Patent Documents 1 and 2, and a rotary interfolder as disclosed in Patent Documents 3 and 4 below.

Conventional examples of a manufacturing method using a multi-stand type interfolder include the following. That is, a first raw fabric roll (generally referred to as a jumbo roll) is prepared by irrigating and winding a papermaker's paper in a papermaking machine, then setting the first raw fabric roll on a ply machine, The continuous sheet is rolled up, and at the same time, the slit is divided into a slit (product width of the tissue paper product or a plurality of multiple widths thereof in the width direction) to produce a secondary fabric roll composed of a plurality of plies.

The secondary fabric rolls made from the ply machine are taken out of the ply machine and set to the required number of multi-stand interfolders. Subsequently, the secondary continuous sheet is unwound from the secondary fabric roll, transferred to a folding mechanism, folded and folded, and then cut into a predetermined length to form a tissue paper bundle, which is then stored in a storage box.

The manufacturing method using the multi-stand type interfolder is advantageous in that productivity is high because it has many (usually 80 to 100) folding mechanisms as compared with the manufacturing method using other folding facilities.

In recent years, there has been a growing demand for a tissue paper product to which a chemical liquid such as a moisturizer (commonly referred to as a "lotion chemical liquid") is applied. For example, there are various manufacturing methods and facilities as disclosed in Patent Documents 5 to 7 Has been proposed. Tissue paper products containing such lotion medicinal solutions have been generally prepared by rotary interfolding (for example, see Patent Document 5). However, the rotary interfolder has a drawback that productivity is low because it is folded and cut simultaneously in the direction of the processing and the direction perpendicular to the processing direction.

Patent Document 1: U.S. Patent No. 4052048 (JP-A-55-1215) Patent Document 2: JP-A-2006-240750 Patent Document 3: JP-A-61-37668 Patent Document 4: JP-A-5-124770 Patent Document 5: JP-A-2004-322034 Patent Document 6: Japanese Published Patent Application No. 2008-525103 Patent Document 7: JP-A-2008-264564 Patent Document 8: JP-A-2008-245780 Patent Document 9: JP-A-2008-183127

Therefore, the present inventors thought that a tissue paper product to which a chemical solution is applied is manufactured by a manufacturing method using a multi-stand type interfolder having high productivity as compared with a rotary type interfolder.

However, in the case of manufacturing by a manufacturing method using a multi-stand type interfolder, there is a problem that a cloth feeding operation is required and a lot of equipment costs are incurred by providing a chemical solution addition process separately from a ply machine or a multi stand type interfolder. In addition, when the chemical solution applying step is provided in the multi-stand type interfolder, a line for manufacturing a tissue paper product to which a chemical solution is to be applied and a line for manufacturing a tissue paper product to which a chemical solution is not to be applied have to be separately provided.

Therefore, a main object of the present invention is to provide a tissue paper product for a tissue paper product, which is excellent in productivity, due to small-scale retrofitting of existing facilities without extensive modification of equipment in manufacturing a second- And to provide a method of manufacturing a roll material roll. Other problems will be clarified by the explanation of the effect field of the present invention to be described later.

Means for solving the above problems are as follows.

[Invention according to claim 6]

The method of manufacturing a secondary fabric roll for a tissue paper product according to claim 1, wherein the application of the first primary liquid is by a rotor damning spraying method.

[Invention according to claim 7]

A plurality of secondary raw rolls obtained by the claims of any one of the above claims are prepared, the rolls are arranged along a line direction in a multi-stand type interfolder, and a plurality of secondary continuous rolls And the stacked sheets are cut by a predetermined length to form a bundle of tissue paper, and the laminated sheet is stored in the storage box. The tissue paper product according to claim 1, ≪ / RTI >

In the slit process in the manufacturing method according to the present invention, a plurality of secondary fabric rolls for tissue paper products manufactured to have a product width of the tissue paper product or a plurality of times thereof are set in a multi-stand type interfolder at the subsequent stage. Subsequently, the secondary continuous roll set in the multi-stand type interfolder is unloaded and fed to the folding mechanism, folded while being folded, cut into a predetermined length to form a tissue paper bundle, and then stored in a storage box.

In the present invention, a first chemical liquid spraying process and a second chemical liquid applying process by a flexographic printing method or a gravure printing method are introduced into a so-called ply machine for continuously producing a second raw material roll for a tissue paper product from a primary raw roll And the chemical solution was applied to the continuous sheet. Therefore, it is advantageous in that investment equipment cost can be minimized because it is possible to cope with a small scale retrofit of the existing grass plant equipment and the ply machine even if the equipment is not greatly modified.

In addition, since the chemical solution spraying process and the chemical solution application process are introduced into the ply machine instead of providing the chemical solution application or coating process in the multi stand type folder, the tissue paper product coated with the chemical solution and the tissue paper product The conversion is merely an improvement in productivity because it is necessary to switch according to the presence or absence of the application of the chemical solution of the secondary fabric roll for the tissue paper product.

Further, in the case of providing the chemical solution applying process in the multi-stand type interfolder, it is conceivable to provide, for example, a large number of chemical solution applying devices as many as the number of the laminated continuous sheets. However, this not only increases the equipment cost, And it is practically difficult to precisely control the application amount in each application device. Compared with this embodiment, the manufacturing method of the present invention is advantageous in that the facility cost and the amount of coating are controlled.

However, in the manufacturing process of the tissue paper by the multi-stand type inter-folder, since the processing ability of the ply machine is designed in accordance with the processing ability of the multi-stand type interfolder, the processing speed of the ply machine is generally 700 to 1100 m / to be. In this case, the production speed of the chemical liquid spraying step and the chemical liquid applying step in the ply machine must likewise be carried out at a high speed of about 700 to 1100 m / min. In such a high-speed ply machine, for example, when a chemical liquid is applied by a transfer method such as gravure, flexo, or roll coating, a large amount of paper dust is generated due to friction between the sheet and the chuck plate roll traveling at high speed, The concentration thereof changes, resulting in an uneven distribution of the coating amount.

Particularly, when it is intended to apply a chemical solution to a sheet to which a certain amount is applied in a large amount, it is desired to obtain a desired application amount by one application, for example, in the case of flexographic printing, the number of lines of anilox roll is increased, The use conditions of such anilox rolls are liable to cause clogging of the chain plate of the anilox roll by the paper powder mixed in the coating liquid, which results in imbalance in the application amount and makes stable operation difficult .

Therefore, it is conceivable to reduce the application amount per one time by taking a form in which the chemical liquid is divided into two sheets and consequently, the clogging phenomenon of the anilox roll is avoided. Although the application of this chemical solution multiple times is theoretically effective in preventing the clogging of the anilox roll, the amount of paper dust tends to increase in reality because the number of friction parts between the sheet and the chucking roll increases to two places. It is difficult to avoid clogging of the anilox roll.

On the other hand, in the form in which the chemical liquid is divided into two sheets and applied to the sheet, the unevenness of the coating in the width direction applied the first time can be canceled by the imbalance of the second coating, and consequently there is an advantage that the coating form becomes less unbalanced in the width direction.

However, in the application by the above-mentioned transfer method, since the chemical solution is applied in the form of pressing the sheet by the chucking roll and the pressing roll, the fiber gap of the sheet is reduced and the volume is not formed well. This tendency is more prominent in the form in which the chemical liquid is divided into two sheets and given to the sheet.

In the present invention, the first chemical liquid spraying step and the second chemical liquid applying step are applied twice. The unevenness of the coating in the width direction applied the first time can be canceled by the unevenness of the second coating, resulting in a coating shape with little unbalance in the width direction.

In addition, the application of the first chemical solution is performed by chemical solution spraying. In the chemical solution spraying, there is no friction in the compressed form of the sheet, no paper dust is generated, and stable application is possible. Also, since the fiber clearance is not reduced, a bulky tissue paper can be obtained.

In addition, since the paper dust is appropriately controlled by the first chemical liquid spray, the paper dust is suppressed and the generation of paper dust is suppressed in the second transfer type application.

In the second chemical solution applying step, the chemical solution is applied by the flexographic printing method or the gravure printing method. The flexographic printing method is advantageous in that the amount of coating can be stabilized in correspondence to the unevenness of the crepe paper even if the processing speed of the flexographic printing plate roll is resin and the number of lines and cell capacity of the anilox roll, And the application amount can be stabilized in response to the viscosity of a broad chemical liquid easily by changing the number or the peak area ratio.

In addition, it is preferable that the chemical liquid application in the second chemical liquid application step is performed by a flexo printing method using a doctor chamber in particular. The doctor chamber type is characterized in that the chemical solution is directly applied to the surface of the anilox roll (transfer concave roll) and the film is made, The coating liquid can be suitably applied even in the case of low-volume coating.

The gravure printing method is less complicated in adjusting the amount of coating since the roll is made of metal as compared with the flexographic printing method, but the gravure printing method can also be adopted because it shows the coating stability in almost the same application amount and width direction.

It is also conceivable to apply the chemical solution in the second chemical liquid application step in the roll coating method instead of the flexographic printing method or the gravure printing method, but it is difficult to obtain the target product quality by causing the unevenness in the application amount in the width direction. It is also conceivable to prepare the chemical solution applying process by the flexo printing method or the gravure printing method first and then the chemical solution spraying step afterwards, but since the plate contacts the sheet by applying the first chemical solution, not.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[Manufacturing equipment and method of primary raw roll]

An example of a manufacturing equipment and a manufacturing method of the primary raw roll will be described with reference to Fig.

The wet paper W is fed to the wire part 311 from the head box 301 to form the wet paper W and the wet paper W is fed to the felt part 321 of the press part 321 as shown in Fig. (Dewatering process). The dewatering rollers 323 and 324 are connected to the dewatering unit 322 through a pair of dewatering rolls 323 and 324. Then, the dehydrated wet paper W is attached to the surface of the Yankee dryer 331 partially covered with the Yankee dryer hood 332, dried and peeled off by the doctor blade 333 to form the dry paper S 1 (drying step).

The back surface of the reed S 1 is guided by the first winding means 341 having the winding drum 342 while guiding the reed S 1 by the guiding rolls 343 and 344, (Referred to as a "jumbo roll") JR is formed by winding the sheet material S1 so as to face the sheet material (first winding process). The rear surface of the dry paper sheet S1 (the first continuous sheets S11 and S12 described later) means the surface opposite to the surface of the Yankee dryer 331 which is in contact with the cylinder (the surface opposite to the dryer).

When papermaking is performed as described above, appropriate additives such as a dispersing agent, a dry strength agent, a wet strength agent, a softening agent, a releasing agent, an adhesive, a pH adjuster such as caustic soda, a defoaming agent, a preservative, a slime control agent, .

The dry paper S1 peeled off by the doctor blade 333 may be smoothed by calendering means (not shown).

[Equipment for manufacturing secondary fabric rolls for tissue paper products]

As shown in Fig. 11, the primary raw roll (JR) manufactured by the above-described manufacturing facility, method, or the like is used in the production facility X1 (ply machine X1) of the secondary raw material roll for the tissue paper product according to the present invention, And sets at least two primary rolls (JR, JR).

The ply machine X1 is formed by laminating the primary continuous sheets (S11 and S12 in the illustrated example) unwound from the primary raw material rolls JR and JR along the continuous direction thereof, And a ply means 51 for forming a sheet S2.

In the example shown in Fig. 11, the ply means 51 is configured such that the surfaces of the primary continuous sheets S11 and S12 released from the pair of primary raw rolls JR are respectively the surfaces of the laminated continuous sheet S2 The back surface of each of the first continuous sheets S11 and S12 may be the surface of the laminated continuous sheet S2 and the back surface of any one of the first continuous sheets S11 and S12 may be the laminated continuous sheet S2. (S2) and the other surface is the surface of the laminated continuous sheet (S2). In particular, the surface of the primary continuous sheets S11 and S12 (dry paper sheet S1) is in contact with the glossy surface of the Yankee dryer 331 at the time of drying, It is most preferable that the surfaces of the primary continuous sheets S11 and S12 (dry paper sheet S1) are respectively the surfaces of the laminated continuous sheet S2.

A pair of first liquid medicament spraying means (40A, 40B) for applying a liquid medicament to the laminated continuous sheet (S2) coming out of the ply means (51) at the rear end of the ply means (51) 53B are formed on the downstream side of the second chemical liquid application means 53A, 53B and the second chemical liquid application means 53A, 53B are formed on the downstream side of the second chemical liquid application means 53A, Slit means 55 for slitting the continuous sheet S2 to a product width of the tissue paper product or a multiple thereof is disposed. A laminated continuous sheet S2 slit by the slit means 55 is coaxially wound on the rear end of the slit means 55 to form a plurality of secondary fabric rolls R having a product width or a multiple of the product width of the tissue paper product And winding means (56) for forming it is formed. Here, the winding means 56 has two winding drums 56A for guiding the slitted continuous laminated sheets S2 to the secondary fabric roll R, and these two winding drums 56A are disposed in the secondary And contacts the outer circumferential surface of the fabric roll (R) to guide the laminated continuous sheet (S2).

(Calendar means)

At least one calender means 52 for calendering the laminated continuous sheet S2 may be formed in the manufacturing equipment X1 of the secondary fabric roll for the tissue paper product.

The type of calender in the calender means 52 is not particularly limited, but it is preferable to use a soft calender or a chilled calender for the reason of improvement of smoothness of the surface and adjustment of paper thickness. The soft calender is a calender using a roll coated with an elastic material such as urethane rubber, and the calender calender is a calender made of a metal roll.

The number of calendar means 52 can be changed as appropriate. The provision of a plurality of units has the advantage of being able to be sufficiently smoothed even if the processing speed is high, and is disadvantageous in terms of space.

When two or more calendering means 52 are provided, they may be juxtaposed horizontally, vertically, or obliquely, or they may be arranged in a mixed manner. The horizontal inclination can reduce the inclined angle, so that the processing speed can be increased. If the vertical inclination is provided, the installation space can be reduced. The inclined angle referred to herein means an angle of a space (a part of an arc at a cross section orthogonal to the axis) in which the sheet is in contact when viewed from the axial center of the roll (the same shall apply hereinafter).

It is preferable that the calender type, the nip line pressure, the nip number, and the like in calendering treatment conditions are also used as control factors, and these control factors are suitably changed according to the quality of the tissue paper required, that is, paper thickness or surface property.

The position of the calender means 52 is not particularly limited, but the front end of the first chemical liquid spraying means 40A, 40B is preferably the rear end of the ply means 51. [ It is possible to make the front end of the contact embossing means 54 as the rear end of the second chemical solution applying means 53A and 53B but it is not a preferable form because it acts in the direction of inhibiting the volume by pressing the gap of the fiber to which the chemical solution is applied .

(Chemical liquid spraying means)

The first chemical liquid spraying means 40A, 40B is not particularly limited, but may be a case of a nozzle damper spraying method other than the nozzle-type spraying method described later and illustrated.

In the nozzle type spraying apparatus, examples of the type of the spraying nozzle include a hollow conical nozzle for spraying in an annular shape, a conical nozzle for spraying in a circular shape, a rectangular nozzle for spraying in a square, a charging nozzle, and a fan type nozzle. The number of nozzles, the number of nozzle arrangements, the number of nozzle arrangements, or the spraying distance, the spraying pressure, the spraying angle, the concentration of the spraying liquid, the viscosity, and the like are appropriately selected and used so as to be uniformly sprayed in the width direction of the dry paper S2 .

In addition, as for the method of atomizing in the nozzle type atomizing apparatus, it is possible to select and use two kinds of methods of one fluid type or two fluid type. In the one-fluid spraying method, direct pressure is applied to the chemical liquid to be sprayed by using compressed air, and the air is ejected from the nozzle through the fine holes formed in the side surface of the nozzle near the ejection port. In addition, the two-fluid spraying method mixes with the liquid spraying the compressed air in the nozzle, the internal mixing type which atomizes, the mixed with the liquid spraying the compressed air from the outside of the nozzle, the external mixing type which atomizes, And a collision type in which the particles are further homogenized and made into fine particles.

On the other hand, for the rotor damning coating apparatus, a device for spraying a liquid sprayed on a disk rotating at high speed and fine-immobilizing the liquid by the centrifugal force of the disk is used. The diameter of the droplet is controlled by changing the number of revolutions of the disk, And controls the spray liquid amount (applied amount) by changing the liquid amount. The rotor damning coating apparatus has an advantage that it can uniformly apply a small amount of spray liquid to the paper surface while suppressing non-invasive scattering, and adjust the spraying speed, spray particle diameter and the like easily.

In order to uniformly spray the chemical liquid on the surface of the dry paper (S2), it is preferable that the diameter of the non-droplet particle of the atomized chemical liquid is as small as possible. However, if the invasion becomes too small, the atomized air is splashed or invincible due to the air accompanying the surface of the guards (S2), and particularly when the guiding speed of the guards (S2) is fast, . Therefore, in the case of the two-fluid system, the mixture ratio of the spraying liquid and the compressed air, and the concentration and viscosity of the chemical liquid are appropriately controlled to adjust the spraying distance, the spraying pressure, the spraying angle, In addition, in the case where the influence of the accompanying air on the ignition of the dust is great, it is possible to install a suction device or a disturbance plate (rectification plate) for removing the entrained air, and apply a high voltage to the tip of the spray nozzle, A charging electrode (electrostatic spraying method) for enhancing the inviolability of adhesion to paper can be added.

The inert particles which are not coated on the surface of the dry paper S2 and floated as a mist can be sucked and recovered and sprayed again.

Fig. 28 shows an example of the nozzle type spraying method, particularly, the two-fluid type chemical liquid spraying means 40A and 40B. The chemical solution spraying means (apparatus) 40A, 40B has a chemical solution passage 40a at the center and an air passage 40b around the chemical solution passage 40a. The chemical solution ejected from the tip of the chemical solution passage 40a is passed through the air passage 40b ), So that the chemical liquid is sprayed in a nearly conical shape. Reference numeral 40c denotes an external protective casing which protects the nozzle from paper dust or the like, and can clean the nozzle by air passing through the purge air passage 40d, if necessary. This kind of chemical liquid spraying means 40A and 40B can be formed at one or a plurality of intervals in the width direction of the dry paper S2.

As described above, when the sprayed chemical liquid is splashed or is invaded by air or the like accompanying the surface of the dry paper S2, especially when the dry paper S2 runs at a high speed, invincibility is not adhered to the surface of the dry paper S2 . Therefore, as shown in FIG. 29, if necessary, air (air) sprayed from the air supply path 40f formed in the casing 40e from the periphery of the one-fluid or two-fluid chemical liquid spray means (spray nozzles) 40A, It is possible to suitably apply the chemical liquid to the dry paper S2 by surrounding the spray liquid medicines from the chemical liquid spray means (spray nozzles) 40A and 40B.

Fig. 30 shows an example of the rotor damning coating apparatus 40X. This is because the rotating rotor 40o is formed in the cover accommodating chamber 40p which is installed as needed and the chemical liquid is sprayed from the air blowing port 40q of the rotating rotor 40o to the paper reeling (S2).

The amount of the chemical solution applied to the dry paper S2 in the first chemical liquid spraying means 40A, 40B is preferably 0.5 to 1.5 g / m 2, more preferably 0.7 to 1.2 g / m 2. The amount of the chemical solution applied to the second chemical solution application means 53A, 53B is preferably 0.5 to 1.5 g / m 2, more preferably 0.7 to 1.2 g / m 2. Therefore, it is preferable that the total amount is 1.0 to 3.0 g / m < 2 > per one ply. When two-ply products are to be obtained, the total amount of two plies is preferably 2.0 to 6.0 g / m 2, but it is particularly preferably 2.5 to 5.0 g / m 2. The effect of the present invention described above is more conspicuous when the balance of the chemical liquid application amount is set as the above ratio between the first order and the second order.

Even if there is a difference in the application amount between the first chemical solution spraying means 40A, 40B and the second chemical solution applying means 53A, 53B, after the coating is performed as the secondary raw material roll R, Since the plies are in contact with each other within a period of time (8 hours or more), the amount of the chemical solution is gradually diffused and permeated, so that the applied amount of the chemical liquid is equalized.

(Chemical solution)

The chemical liquid used in the present invention is preferably common to the first chemical liquid spraying means (40A, 40B) and the second chemical liquid applying means (53A, 53B) for affinity.

It is preferable that the viscosity is from 1 to 700 mPa · s, particularly from 50 to 400 mPa · s (40 ° C.) at 40 ° C. from the viewpoint of high-speed application of the chemical solution by the second chemical solution application means 53A and 53B. When the viscosity is less than 1 mPa · s, the chemical liquid tends to scatter on a roll such as anilox roll or a chucking roll. On the contrary, when the viscosity is greater than 700 mPa · s, the amount of coating on each roll or continuous sheet tends to be difficult to control.

It is preferable that the chemical liquid is particularly water-based, and it preferably contains 70 to 90% of polyol, 1 to 15% of water and 0.01 to 22% of functional drug as its components.

Examples of polyols include polyhydric alcohols such as glycerin, diglycerin, propylene glycol, 1,3-butylene glycol, polyethylene glycol and derivatives thereof, and saccharides such as sorbitol, glucose, xylitol, maltose, maltitol, mannitol and trehalose.

Functional agents include softening agents, surfactants, inorganic and organic fine particle powders, and oily components. Softeners and surfactants have the effect of giving softness or smoothing the surface of the tissues and applying anionic surfactants, cationic surfactants and amphoteric surfactants. The fine particles of inorganic and organic fine particles make the surface smooth and tactile. The oily component has a function of increasing activity, and higher alcohol such as liquid paraffin, cetanol, stearyl alcohol, and oleyl alcohol can be used.

Further, as a medicine for maintaining the moisture retention of the polyol as a functional agent, there may be mentioned a combination of a hydrophilic polymer gelling agent, collagen, hydrolyzed collagen, hydrolyzed keratin, hydrolyzed silk, hyaluronic acid or its salt, ceramide, A humectant may be added.

In addition, as a functional agent, an emulsifier such as a perfume or various natural extracts, an emulsifier which stabilizes vitamins, a compounding ingredient, a deodorant such as a defoaming agent for suppressing the foaming of a chemical solution and stabilizing application, a fungicide, . It may also contain vitamin C and vitamin E antioxidants.

It is preferable that the above components include polyhydric alcohols such as glycerin and propylene glycol as main components to stabilize the viscosity and the application amount of the chemical liquid.

The temperature for application of the chemical solution is preferably 30 占 폚 to 60 占 폚, preferably 35 占 폚 to 55 占 폚.

Further, when the crepe ratio of each primary continuous sheet constituting the laminated continuous sheet S2 is made different, the crease ratio of the primary continuous sheet (the primary continuous sheet S11 side in the illustrated example) It is also proposed to apply a chemical solution. For example, in the example shown in Fig. 11 and Fig. 24, the second liquid chemical application means 53B for directly applying the chemical liquid to the first continuous sheet S11 among the two second chemical liquid application means, It is preferable to apply more chemical solution than the application means 53A.

Even if there is a difference in the application amount between the second chemical solution application means 53A and 53B, the ply mutual contacts within the time (8 hours or more) from the time of storage as the secondary raw material roll R to the time of the fold processing The chemical liquid is gradually diffused and permeated so that the applied amount of the chemical liquid is equalized, and the difference in the amount of applied between ply is reduced.

24 (A) is a sectional view of a laminated continuous sheet S2 laminated with two plies before application of a chemical solution (a cross-sectional view taken parallel to the MD direction). When the chemical solution is applied to both sides of the laminated continuous sheet S2 laminated with two ply, a large amount of chemical solution is applied to the side of the first continuous sheet S11 with a difference in the amount of the chemical solution on both sides. After the chemical solution is applied, the laminate is integrated by contact embossing CE before the laminated continuous sheet S2 is completely stretched, and the product is cut into a product width by the slit means 55 (Fig. 24 (B)). Thereafter, the laminated continuous sheet S2 is wound around the winding means 56 and left to infiltrate the chemical liquid. The primary continuous sheets S11 and S12 constituting the laminated continuous sheet S2 to which the chemical liquid is applied by the secondary liquid chemical application means 53 are mainly elongated in the MD direction. At this time, although the first continuous sheet S11 coated with a larger amount of the chemical solution is larger in elongation percentage than the first primary continuous sheet S12, the primary continuous sheets S11 and S12 are fixed to each other with the contact embossing CE The surface of the elongated primary continuous sheet S11 is wrinkled (24 (C)). If the base paper having a high crepe ratio is used for the primary continuous sheet S11 with a difference in the crepe ratio of the laminated continuous sheet S2, the elongation percentage of the primary continuous sheet S11 and the primary continuous sheet S12 You can make a difference.

The crepe is formed by the difference between the dryer speed and the winding speed after the raw paper is dried with the Yankee dryer 115 and then separated from the Yankee dryer 115 by the doctor blade 117. This crepe adjusts its shape by adhering the paper to the Yankee dryer 115, which has slight irregularities in the adhesion and is not uniformly distributed in the textile, . This imbalance becomes more significant as the crepe ratio becomes larger.

This unbalance of the crepe as well as the elongation at the time of application of the chemical solution causes an unbalance, which is formed into a three-dimensional fine waveform. This waveform is not visualized because tension is applied during fabric seasoning, but it is processed into a product, restored, restored, and made current. The larger the amount of the chemical solution applied to the sheet is, the larger the crepe shape and the waveform of the sheet are. The smaller the amount of the chemical solution applied to the sheet is, the smaller the crepe shape is. Therefore, the volume effect can be increased by changing not only the coating amount but also the crepe ratio.

In the case where the first continuous sheets S11 and S12 having different crepe ratios are stacked and made into a product with respect to quality, if the chemical solution is not applied, the tissue paper as a product will have a different bulk feeling on both sides (Fig. 25 (A)). However, by applying a large amount of the chemical solution by the first continuous sheet S11 having a larger unevenness of the surface (the crepe ratio is higher), the primary continuous sheet S11 is stretched at a higher elongation rate than the primary continuous sheet S12 The first continuous sheet S11 is corrugated and the volume of the laminated sheet is increased since it is fixed parallel to the MD direction by the contact embossing (not shown) (Fig. 25 (B)).

There is a possibility that the feel and feeling on both sides of the product may differ due to the difference in the amount of the chemical solution applied. However, the second raw material roll R is allowed to stand in the roll state before being supplied to the next step Since the surfaces of the other first continuous sheets S11 and S12 are maintained in a state of being opposed to each other (chemical liquid infiltration process, Fig. 26), the chemical liquid components between the successive sheets are slightly shifted (gray arrows in the figure) . The white arrows in FIG. 26 indicate the infiltration direction of the chemical liquid component.

In the present invention, a flexographic printing method or a gravure printing method is used as the second chemical liquid applying means 53. [ At this time, the processing speed of the sheet is set to 100 to 1100 m / min, preferably 350 to 1050 m / min, and particularly preferably 450 to 1000 m / min. If the rate is less than 100 m / min, the productivity is low. On the other hand, if the rate is more than 1100 m / min, the coating unevenness tends to occur and the scattering rate of the chemical solution tends to increase.

In the case of the flexographic printing system, the number of lines of the flexographic printing plate roll is set to 10 to 60, preferably 15 to 40, and particularly preferably 20 to 35. When the number of lines is less than 10, unevenness of application occurs frequently. On the other hand, when the number of lines exceeds 60, the paper becomes easily clogged with paper dust. The number of lines of the anilox roll is 10 to 300, preferably 25 to 200, and particularly preferably 50 to 100. When the number of lines is less than 10, unevenness of application occurs a lot. On the contrary, when the number of lines exceeds 300, paper dust easily becomes clogged. The cell capacity of the Anilox roll is 10 to 100 cc, preferably 15 to 70 cc, and particularly preferably 30 to 60 cc. If the cell capacity is less than 10 cc, the desired amount of application can not be obtained. Conversely, if the cell capacity exceeds 100 cc, the amount of the chemical solution to be scattered increases.

In the flexographic printing method or the gravure printing method, the coating amount can be stabilized even if the processing speed is high, and the viscosity of a broad chemical liquid can be stably applied with one roll.

The means (the calender means 52 and the contact embossing means 54 in the example of Fig. 11) arranged before and after the second chemical liquid application means 53 are preferably disposed close to each other. In the case of producing a tissue paper product to which the chemical solution is not applied, the laminated continuous sheet S2 is directly transferred from the front end to the rear end of the second chemical solution applying means 53, passes through the second chemical solution applying means 53 It is possible to easily switch the presence or absence of the chemical solution application. For example, in the case of producing a tissue paper product to which a chemical solution is not applied in the manufacturing facility X1 of the second raw material roll for a tissue paper product shown in Fig. 11, as shown by the two-dot chain line in Fig. 11, To the contact embossing means 54 directly from the calender means 52 and to send the laminated continuous sheet S2 without passing through the second chemical liquid applying means 53. [

≪ Embodiment 1 of the Doctor Chamber Form &

Here, an example of the doctor chamber format in the flexographic printing method is described.

As shown in Fig. 12, the chemical solution shroud 53A serving as one of the doctor chambers is arranged so that the doctor chamber 61A containing the chemical solution is opposed to the rotatable anilox roll 63A, So that the chemical liquid can be transferred to the anilox roll 63A. A chuck roll 64A which is in contact with the anilox roll 63A and makes contact with one side of the laminated continuous sheet S2 is rotatably provided so as to transfer the chemical solution from the anilox roll 63A to the chuck roll 64A It is possible. The laminated continuous sheet S2 is fed from the chuck roll 64A to the laminated continuous sheet S2 while applying pressure to the laminated continuous sheet S2 by the elastic roll 65A opposed to the laminated roll 64A with the laminated continuous sheet S2 interposed therebetween. The chemical solution is applied.

In this embodiment, the chemical solution shroud 53A is located on the surface side of the laminated continuous sheet S2 opposed to the roller 54A of the contact embossing means 54 described later and also against the winding drum 56A described above. Further, a supply pump (not shown) for applying a chemical solution to the doctor chamber 61A and a discharge pump (not shown) for returning the chemical solution from the doctor chamber 61A are provided in the doctor chamber 61A .

On the other hand, as shown in Fig. 12, the chemical solution shroud 53B serving as the other doctor chamber type is arranged to face the doctor chamber 61B, with the doctor chamber 61B containing the chemical solution being opposed to the rotatable anilox roll 63B. So that the chemical liquid can be transferred to the anilox roll 63B. A chaining plate roll 64B which is in contact with the anilox roll 63B and makes contact with the other surface of the laminated continuous sheet S2 is rotatably provided so that the chemical liquid is supplied from the anilox roll 63B to the chicle plate roll 64B And the like. The laminated continuous sheet S2 is stretched from the chop roll 64B while applying pressure to the laminated continuous sheet S2 by the elastic roll 65B opposed to the laminated roll 64B with the laminated continuous sheet S2 interposed therebetween, The chemical solution is applied.

In the present embodiment, this chemical solution shroud 53B is located on the other surface side of the laminated continuous sheet S2 which does not face the roller 54A and does not face the winding drum 56A. A supply pump (not shown) for applying a chemical solution to the doctor chamber 61B and a discharge pump (not shown) for returning the chemical solution from the doctor chamber 61B are also provided in the doctor chamber 61B .

Therefore, chemical fluids are applied to the both surfaces of the laminated continuous sheet S2 from the chemical solution shroud 53A and the chemical solution shroud 53B, respectively. At this time, the chemical solution shroud 53A is pressed against the roller 54A by the chemical- The chemical liquid can be applied to each of the laminated continuous sheet S2 from both sides of the laminated continuous sheet S2 while reducing the amount of application of the side surface of the laminated continuous sheet S2 with respect to the amount of application of the other side of the chemical liquid shell 53B.

If the total amount of coating on both sides is 2.5 to 5 g / m < 2 >, and the coating amount of the outer circumferential surface of the secondary fabric roll (R) as the ply fabric roll is made smaller than the coating amount of the inner circumferential surface of the secondary fabric roll Of the total amount of the chemical solution on both sides of the secondary fabric roll R is preferably 20% or more but less than 50% of the total amount of the chemical roll on the outer circumferential surface of the secondary fabric roll R. The specific value is a balance between smoothness and quality of the secondary fabric roll R, The optimum conditions vary depending on the thickness of the sheet, the permeability of the chemical liquid, and the metastability, and therefore, it varies in the above range.

Concretely, it is conceivable that not only the amount of coating per side is changed but also the number of lines of flexo plate is about 15 to 40, and the peak area rate is about 20 to 40% so that the liquid medicine does not scatter. Immediately thereafter, the dot pattern remains and the coated portion and the uncoated portion are instantaneously formed.

Therefore, according to this embodiment, since the plate is made of resin and elasticity by using the flexographic printing method, even if there is some irregularity in the sanitary thin paper sheet, the laminated continuous sheet S2 is not easily wrinkled because it can be adjusted by the printing pressure. On the other hand, by using the flexographic printing method, even if the processing speed is high, the application amount can be stabilized and the viscosity of a broad chemical liquid can be stably applied with one roll. Concretely, even when applying the chemical liquid to be a chemical liquid at a coating amount to be described below while conveying the laminated continuous sheet S2 at a speed of 700 m / min or more, preferably 900 m / min or more, (S2).

The conditions of the second chemical liquid application means 53 attached to this embodiment are as follows.

In the second liquid chemical applying means of the two-roll flexo type, it is necessary to provide a paper laminar air filtering apparatus included in the chemical liquid circulating in the coating apparatus such as the chemical liquid tank. However, In the case of using the second chemical liquid application means 53, the load of the filtration apparatus is reduced because paper dust or the like is reduced. It is preferable to control the temperature of the chemical liquid in the coating device such as the doctor chambers 61A and 61B and stabilize the viscosity of the chemical liquid. In this case, a heater may be installed in the intermediate tank and piping connected to the doctor chambers 61A and 61B. On the other hand, when the coating amount is controlled by the moisture content in the width direction of the laminated continuous sheet S2 during operation, it is possible to always check the water amount and unbalance in the width direction, for example, by using an infrared tester or the like. 12, brush rolls 69A and 69B having a plurality of brushes are formed in contact with the chop rolls 64A and 64B to scrape off the paper dust which is always to be attached to the chop rolls 64A and 64B It is possible to prevent clogging of the chill rolls 64A and 64B and the anilox rolls 63A and 63B, thereby enabling stable operation.

≪ Embodiment 2 of the doctor chamber type &

Next, the second embodiment of the doctor chamber type will be described in detail with reference to the structures shown in Figs. 14 and 15 in detail.

The illustrated chemical liquid supply apparatus 100 is provided for one of the two chemical fluid guide shafts 53A and 53B by the doctor chamber type flexographic printing system constituting the second chemical liquid application means 53, It is. The left and right direction of the chemical liquid supply device 100 shown in FIG. 14 is defined as the X-axis direction, and the vertical direction is defined as the Y-axis direction.

The chemical liquid supply apparatus 100 includes a storage tank 110 for storing the chemical liquid L, an extrusion section 120 for pushing out the chemical liquid L in the storage tank 110, a chemical liquid pushed out from the extrusion section 120, An inlet 140 for drawing a part of the chemical solution L stored in the doctor chamber 130 to the tank 110 and a supply unit 140 for supplying the chemical solution L from the doctor chamber 130. [ A drug solution transferring section 150 for transferring the drug solution L to the surface of the laminated continuous sheet S2 and a rotation section 160 for winding the laminated continuous sheet S2 around the periphery of the drug solution transfer section 160 .

Therefore, the doctor chambers 61A and 61B serve as the doctor chambers 130 in the present embodiment, and the elastic rolls 65A and 65B serve as the turning portions 160 in the present embodiment.

The storage tank 110 is a tank for storing the chemical liquid L therein and an extrusion hose 121 of the extrusion portion 120 and a feed hose 141 of the extrusion portion 140 to be described later are inserted into the liquid layer.

The extruding unit 120 includes an extrusion hose 121 inserted in the storage tank 110 and a feed pump 122 for pushing out the chemical liquid L stored in the storage tank 110 and supplying the chemical liquid L to the doctor chamber 130. [ And an adjustment valve 123 for adjusting the amount of extrusion (flow rate) of the chemical liquid L by the supply pump 122.

The extrusion hose 121 is a hose having one end inserted into the storage tank 110 and the other end connected to the inlet 132 of the doctor chamber 130 and functions as a flow path for transporting the chemical liquid L in the storage tank 110 do. The supply pump 122 is mounted on the extrusion hose 121 and driven by a drive motor (not shown) to pressurize and feed the chemical liquid L in the storage tank 110 to the doctor chamber 130. The adjustment valve 123 adjusts the flow rate of the chemical liquid L pushed by the supply pump 122 by opening and closing the valve.

The inlet unit 140 includes an inlet hose 141 inserted into the storage tank 110 and a suction pump 142 for drawing the chemical liquid L into the storage tank 110. [

The inlet hose 141 is a hose whose one end is inserted into the storage tank 110 and the other end is connected to the lead portion 133 of the doctor chamber 130 to be described later. And serves as a flow path to be conveyed to the storage tank 110.

The suction pump 142 is mounted on the inlet hose 141 and is driven by a drive motor (not shown) to suck the chemical liquid L led out from the lead-out portion 133 and discharge it to the storage tank 110 (outside).

The supply pump 122 for applying the chemical solution to the doctor chambers 61A and 61B is provided with a supply pump 122 for pushing out the chemical solution L stored in the storage tank 110 and supplying the chemical solution L to the doctor chamber 130, And a discharge pump for returning the chemical liquid from the doctor chambers 61A and 61B is a suction pump 142 for attracting the chemical liquid L to the storage tank 110 in this embodiment.

The doctor chamber 130 includes a main body 131 disposed adjacent to the anilox roll 151 to store the chemical liquid L and an introduction part 132 connecting the extrusion part 120 and the body part 131. [ And a lead-out part 133 connecting the lead-in part 140 and the main body part 131.

The main body part 131 is a main body part of the doctor chamber 130 and includes a storage part 131a and blades 131b and 131c.

The storage unit 131a supplies the chemical liquid L stored in the anolox roll 151 to the anilox roll 151. The storage unit 131a is connected to the inlet unit 132 and the lead unit 133, And a portion of the chemical liquid L introduced into the storage portion 131a from the introduction portion 132 is led out through the lead portion 133 so that the supply amount to the anilox roll 151 becomes constant.

Therefore, the anilox rolls 63A and 63B described above become the anilox rolls 151 in the present embodiment.

The blades 131b and 131c are formed so as to abut the anilox roll 151 and narrow the width of the chemical liquid L in a state in which the blades 131b and 131c are pressed by the anilox roll 151. [

The introduction part 132 is a tubular joint in which one end is connected to the main body part 131 and the other end is connected to the extrusion hose 121 of the extrusion part 120 to connect the extrusion part 120 and the body part 131, The chemical liquid L supplied by the pump 122 can be introduced into the storage portion 131a of the body portion 131. [

The lead-out portion 133 is composed of a joint 133a, a hole 133b and a tube 133c as shown in Figs. 14 and 15.

The joint 133a is a tubular joint in which one end is connected to the main body 131 and the other end is connected to the inlet hose 141 of the inlet portion 140 to connect the inlet portion 140 and the body portion 131. [

The hole portion 133b is an opening portion formed on the upper surface of the joint 133a and having a predetermined diameter.

That is, since the hole 133b is formed in the joint 133a, the chemical liquid L in the joint 133a comes into contact with the outside air. Therefore, even when the chemical liquid L is sucked by the suction pump 142 when the chemical liquid L is circulated by discharging a part of the chemical liquid L introduced from the introduction part 132 (leading out from the lead-out part 133) The chemical liquid L can be brought into contact with the outside air by the portion 133b so that the inside pressure can be brought close to the outside air pressure so that fluctuation of the inside pressure in the doctor chamber 130 can be suppressed.

The hole portion 133b may be formed so as to communicate with the storage portion 131a on the upper surface of the main body 131, for example, since fluctuation of the internal pressure in the doctor chamber 130 is suppressed.

The tube 133c is a transparent or semitransparent tubular member whose lower end is connected to the hole 133b and which extends upward. It is visually confirmed whether or not the chemical liquid L flows into the tube 133c through the hole portion 133b when the chemical liquid L is circulated by discharging a part of the chemical liquid L introduced from the introduction portion 132 .

That is, when it is confirmed that the liquid L has been introduced into the tube 133c, the amount of the chemical liquid L stored in the storage unit 131a is excessive (the chemical liquid L is supplied to the anilox roll 151) ) Can be grasped. Therefore, a user who visually confirms the excessive state can, for example, adjust the extrusion amount (flow rate) of the chemical liquid L by operating the adjustment valve 123, thereby overcoming the excessive state.

Further, since the inside of the tube 133c is hollow and the top end thereof is in contact with the outside air, the action of the hole 133b is not canceled.

The drug solution transferring unit 150 is formed of a roll plate 151 formed between the anilox roll 151 and the anilox roll 151 to which the chemical liquid L is supplied in the doctor chamber 130 and a rotation plate 160 152).

That is, the above-mentioned chuck rolls 64A and 64B are the chuck rolls 152 in this embodiment.

The anilox roll 151 is formed so as to abut the blades 131b and 131c of the doctor chamber 130 and the chemical liquid L supplied from the opening of the storage portion 131a of the doctor chamber 130 is adsorbed on the peripheral surface .

Since the anilox roll 151 has a columnar shape and is rotatable about an axis orthogonal to the XY plane, the chemical liquid L adsorbed on the circumferential surface as described above is rotated by the rotation of the plate roll 152 ).

14) is wound around the anilox roll 151 and the rotatable portion 160, and the circumferential surface of the chuck roll 152 is wound around the anilox roll 151 and the rotatable portion 160, (The laminated continuous sheet S2), and is rotatable about an axis orthogonal to the XY plane.

Therefore, the rotary plate 160, which is in contact with the left end of the plate roll 152, rotates in the r2 direction by rotating in the r1 direction, and rotates the anilox roll 151 in the r1 direction. That is, the chucking plate roll 152 acquires the chemical liquid L adsorbed on the circumferential surface of the anilox roll 151 at point P2 and carries it to the point P1 by the rotational movement in the r2 direction, It can be transferred.

Therefore, even when the chemical liquid L adsorbed by the anilox rolls 151 remains unevenly distributed on the circumferential surface of the anilox rolls 151, they are transferred to the peripheral surface of the rolls 152, The chemical liquid L can be uniformly transferred to the sheet S2.

The rotating portion 160 is a cylindrical member which is formed adjacent to the chucking roll 152 and rotates about an axis (for example, r1 direction in Fig. 14) perpendicular to the XY plane by a driving force applied from a motor or the like And is configured to be able to grip the laminated continuous sheet S2 on the peripheral surface. Therefore, the rotary motion unit 160 rotates the chuck plate roll 152 and the anilox roll 151 while rotating the laminated continuous sheet S2, which is supplied by rotating in the r1 direction, to the circumferential surface, The chemical liquid L can be transferred from the chucking roll 152 at the time.

Although the direction of the rotational movement of the single rotation unit 160 is the r1 direction in FIG. 14, it may be configured to rotate in the r2 direction. In this case, the anilox roll 151 and the chaining plate roll 152 rotate in the direction opposite to that of Fig. 14 (i.e., the anilox roll 151: r2 direction, the chucking plate roll 152: r1 direction).

Next, the circulation operation of the chemical liquid L by the chemical liquid supply apparatus 100 according to the present embodiment will be described.

The supply pump 122 is first driven and the chemical liquid L is pushed out of the storage tank 110 and discharged through the extrusion hose 121 and the inlet portion 132 of the doctor chamber 130 to the storage portion 131a of the body portion 131 .

The chemical liquid L in the storage part 131a is supplied to the anilox roll 151 and the chemical liquid L is supplied onto the laminated continuous sheet S2 through the chuck roll 152 Transcribe.

Then, the suction pump 142 is driven and a part of the chemical liquid L in the storage part 131a is discharged toward the storage tank 110 through the lead-out part 133 and circulated. At this time, fluctuation of the internal pressure in the doctor chamber 130 is suppressed by outside air contact through the hole portion 133b in the joint 133a of the lead-out portion 133. [

When it is confirmed that the chemical liquid L has flowed into the tube 133c during the circulation, the flow rate of the chemical liquid L is adjusted by operating the adjustment valve 123.

As described above, according to the chemical liquid supply apparatus 100 according to the present embodiment, the storage tank 110 storing the chemical liquid L and the chemical liquid L stored in the storage tank 110 can be supplied to the doctor chamber 130 The chemical liquid L stored in the main body part 131 of the doctor chamber 130 and the supply pump 122 for supplying the main body part 131 through the extrusion hose 121 are sucked to the storage tank 110 The doctor chamber 130 connects the extrusion hose 121 and the main body 131 and discharges the chemical liquid L supplied by the supply pump 122 And a part of the chemical liquid L introduced into the main body part 131 from the introduction part 132 is led out from the introduction part 132. The introduction part 132 connects the inlet hose 141 and the main body part 131, And a hole 133b is formed on the upper surface of the joint 133a of the lead-out portion 133. The lead-out portion 133 is provided with a hole 133b.

In the chemical liquid supply apparatus 100, the hole 133b is provided on the upper surface of the joint 133a of the lead-out portion 133. [ Therefore, when the chemical liquid L in the main body part 131 is discharged by using the suction pump 142, the chemical liquid L is in contact with the outside air by the hole 133b, The fluctuation of the internal pressure in the doctor chamber 130 due to the change in the pressure is suppressed. In the present invention, since the suction pump 142 is used for discharging a part of the chemical liquid L, a flow path for dropping the chemical liquid L is not necessary, and the installation position of the tank 110 is not particularly limited to the doctor chamber 130 and the like.

Therefore, it is said that the chemical liquid supply apparatus 100 can suppress the fluctuation of the internal pressure in the doctor chamber 130 when the chemical liquid L is taken out from the doctor chamber 130, and at the same time, .

The doctor chamber 130 is provided with a transparent or semitransparent tube 133c whose lower end is connected to the hole 133b and is extended upward.

That is, when a part of the chemical liquid L introduced from the introduction part 132 is discharged to circulate the chemical liquid L, it is visually confirmed whether or not the chemical liquid L flows into the tube 133c through the hole part 133b . It is confirmed that the amount of the chemical liquid L stored in the storage part 131a is excessive (the chemical liquid L is supplied to the anilox roll 151) ) Can be grasped. Therefore, a user who visually confirms the excessive state can, for example, adjust the flow rate of the chemical liquid L by operating the adjustment valve 123, thereby overcoming the excessive state.

Further, since the upper end (free end) of the tube 133c is directed downward, foreign matter such as paper dust can be prevented from entering the hole 133b.

≪ Embodiment 3 of the doctor chamber type &

Next, the chemical liquid supply device 200 according to the third embodiment of the doctor chamber type will be described with reference to FIG.

In the chemical liquid supply apparatus 100 according to Embodiment 2 of the doctor chamber type, by visually confirming the inflow of the chemical liquid L into the tube 133c connected to the hole portion 133b, the chemical liquid L ) Is in the overfeed state. However, in the chemical liquid supply device 200 of this embodiment, it is automatically determined whether or not the state has reached the above state, and the result of determination is informed to the user.

In the following description of the chemical liquid supply device 200, differences from the chemical liquid supply device 100 of the second embodiment of the doctor chamber type will be mainly described, and the same reference numerals are given to the same components and the description thereof is omitted.

The lead portion 233 of the present embodiment has a joint portion 133a and a cylindrical portion 133d formed above the hole portion 133b and the hole portion 133b and a cylindrical portion 133d mounted on the cylindrical portion 133d And a sensor unit 133e.

The cylindrical portion 133d is a cylindrical member that is fixedly connected to the peripheral surface of the hole portion 133b by welding or the like at its lower end and is extended upward.

The sensor unit 133e includes a sensor 133f formed on the cylindrical portion 133d and a notification unit 133g mounted on the sensor 133f and informed by interlocking with the detection of the sensor 133f.

The sensor 133f includes, for example, a light emitting element (not shown) that emits light toward the detection target and a light receiving element (not shown) that receives reflected light from the detection object. It is detected whether or not the height of the chemical liquid L flowing into the portion 133d reaches the height position (y1 shown in Fig. 16) where the sensor 133f is formed.

When the height of the chemical liquid L flowing into the cylindrical portion 133d by the sensor 133f is detected to reach the height position where the sensor 133f is formed, the notification portion 133g is, for example, To the user.

The chemical liquid L flowing into the cylindrical portion 133d by the sensor 133f reaches the height position when the chemical liquid L is circulated by discharging a part of the chemical liquid L introduced from the introduction portion 132 It is possible to judge whether or not the amount of the chemical liquid L stored in the storage part 131a is excessive (whether the chemical liquid L is in the excessive supply state with respect to the anilox roll 151) . When the excessive state is reached, the user can recognize this by means of the notification unit 133g. For example, by adjusting the extrusion amount (flow rate) of the chemical liquid L by operating the adjustment valve 123, It is possible to solve the problem.

The cylindrical portion 133d does not cancel out the action of the hole 133b because the inside of the cylindrical portion 133d is hollow and the upper end thereof is in contact with the outside air.

Next, the circulation operation of the chemical liquid L by the chemical liquid supply device 200 according to the present embodiment will be described.

The chemical liquid L is first pushed out of the storage tank 110 by driving the supply pump 122 and the storage portion 131a of the main body portion 131 through the extrusion hose 121 and the introduction portion 132 of the doctor chamber 130 .

The chemical liquid L in the storage part 131a is supplied to the anilox roll 151 by rotating the rotary part 160 and the chemical liquid L is conveyed through the chuck roll 152 to the laminated continuous sheet S2, And transferred onto.

Then, the suction pump 142 is driven and a part of the chemical solution L in the storage part 131a is discharged toward the storage tank 110 through the lead-out part 233 and circulated. At this time, fluctuation of the internal pressure in the doctor chamber 130 through the outside air contact at the hole 133b in the joint 133a of the lead-out portion 233 is suppressed.

It is detected that the height of the chemical liquid L flowing into the cylindrical portion 133d by the sensor 133f during the circulation reaches the height position where the sensor 133f is formed and the notification portion 133g informs the user , The flow rate of the chemical liquid (L) is adjusted by operating the adjustment valve (123).

As described above, according to the chemical liquid supply apparatus 200 according to the present embodiment, the doctor chamber 130 has the cylindrical cylindrical portion 133d having the lower end connected to the peripheral surface of the hole portion 133b and extending upward, A sensor 133f for detecting whether or not the height of the chemical liquid L which is formed in the cylindrical portion 133d and flows into the cylindrical portion 133d reaches a predetermined height position (height position where the sensor 133f is formed) And a notification unit 133g for notifying when the height of the chemical liquid L flowing into the cylindrical portion 133d by the sensor 133f reaches the predetermined height position.

That is, the chemical liquid supply device 200 not only exhibits the same effect as the chemical liquid supply device 100, but also the sensor 133f and the annunciation 133g when the chemical liquid L is circulated, It is possible to automatically determine whether or not the chemical liquid L has reached the overfeed state and inform the user of the determination result, so that the burden of the user to make the state determination is alleviated.

≪ Embodiment 4 of the doctor chamber type &

Next, the chemical liquid supply device 300 of the fourth embodiment in the form of a doctor chamber will be described with reference to Fig.

In the doctor-chamber type chemical liquid supply apparatus 100 according to Embodiment 2 and the chemical liquid supply apparatus 200 according to Embodiment 3, the opening amount of the hole portion 133b is set to be a fixed value. However, in the chemical liquid supply apparatus 300 are configured to adjust their opening amounts.

The following description of the chemical liquid supply device 300 mainly focuses on differences between the chemical liquid supply device 100 of the second embodiment and the chemical liquid supply device 200 of the third embodiment, And a description thereof will be omitted.

The lead portion 333 of the present embodiment includes a joint 133a, a cylindrical portion 133d, a sensor portion 133e and an adjustment portion 133h mounted on the cylindrical portion 133d as shown in Fig. 17 . The adjusting portion 133h is, for example, a needle valve and includes a hole 133j as an opening formed on the upper surface of the joint 133a and a valve body 133i for adjusting the opening amount of the hole 133j .

The hole portion 133j has a shape in which the periphery of the opening having a predetermined diameter is surrounded by an orifice.

The valve body 133i has a needle shaft (not shown) which is disposed above the opening of the hole portion 133j and has a tip tapered and can move up and down. The needle shaft is moved up and down, The amount of opening of the hole portion 133j can be adjusted according to the degree of opening at the time of contact.

The amount of opening of the hole portion 133j can be adjusted by the adjusting portion 133h so that the amount of opening of the hole portion 133j can be adjusted in accordance with the variation in the internal pressure in the doctor chamber 131 Can be adjusted appropriately. Therefore, when it is detected that the height of the chemical liquid L flowing into the cylindrical portion 133d by the sensor portion 133e reaches the height position where the sensor 133f is formed, the control valve 123 is operated By adjusting the amount of extrusion of the chemical liquid L and by adjusting the opening amount of the hole portion 133j by the adjusting portion 133h, the air removing ability by the hole portion 133j is improved (the contact area with the outside air is increased It is possible to take measures to suppress fluctuation in the internal pressure in the doctor chamber 130. [

That is, by suppressing the fluctuation of the internal pressure, the chemical liquid L from the inside of the doctor chamber 130 caused by the fluctuation of the internal pressure or the chemical liquid L on the anilox roll 151 is sucked into the doctor chamber 130 side Or the like is preferably prevented so that the circulation of the chemical liquid L is promoted.

Next, a circulation operation of the chemical liquid L by the chemical liquid supply device 300 according to the present embodiment will be described.

The supply pump 122 is first driven and the chemical liquid L is pushed out of the storage tank 110 and discharged through the extrusion hose 121 and the inlet portion 132 of the doctor chamber 130 to the storage portion 131a of the body portion 131 .

The chemical liquid L in the storage part 131a is supplied to the anilox roll 151 by rotating the rotary part 160 and the chemical liquid L is conveyed to the laminated continuous sheet S2 through the chucking roll 152, Lt; / RTI >

Then, the suction pump 142 is driven and a part of the chemical liquid L in the storage part 131a is discharged toward the storage tank 110 through the lead-out part 333 and circulated. When it is detected that the height of the chemical liquid L flowing into the cylindrical portion 133d by the sensor 133f during the circulation reaches the height position where the sensor 133f is formed and it is known to the user by the notification unit 133g , Manipulation of the adjustment valve 123, or adjustment of the opening amount of the hole portion 133j by the adjustment portion 133h.

As described above, according to the chemical liquid supply apparatus 300 according to the present embodiment, the doctor chamber 130 is provided with the adjusting section 133h for adjusting the opening amount of the hole section 133j.

That is, since the chemical liquid supply device 300 has the same effect as the chemical liquid supply device 100 and the opening amount of the hole portion 133j can be adjusted by the adjustment portion 133h, The fluctuation of the pressure within the doctor chamber 130 can be suppressed more preferably by appropriately adjusting the opening amount of the hole portion 133j in accordance with the fluctuation amount of the internal pressure in the doctor chamber 131. [

In the chemical liquid supply device of each of the above embodiments, the introduction part 132 connected to the extrusion hose 121 and the introduction part 132 connected to the extrusion hose 121 are structured so as to have only one doctor chamber 130, For example, the structure shown in each example shown in Fig. 18 may be adopted.

For example, in FIG. 18 (A), along the anilox roll 151 formed largely and rotating about the rotation axis R0, the left and right sides of the doctor chamber 130 in the width direction D And has an introduction part 132 connected to the extrusion hose 121 at the vicinity of the end. And a lead portion 133 connected to the inlet hose 141 is provided at a central portion of the doctor chamber 130.

18A, the two extrusion hoses 121 are respectively connected to the two introducing portions 132 to supply the chemical liquid L from the vicinity of the left and right ends of the doctor chamber 130, The medicinal liquid L that has flowed from the lead portion 133 at the central portion can be drawn out from the doctor chamber 130. [

18B is a plan view of the doctor chamber 130 in which the outer frame is formed in a substantially rectangular shape along the anilox roll 151 which is formed to be large in width and rotates about the rotation axis R0, And an inlet portion 132 connected to the extrusion hose 121 at the central portion. Two lead portions 133 connected to the inlet hose 141 are provided at left and right portions of the doctor chamber 130 in the width direction D, respectively.

That is, in the example shown in Fig. 18 (B), two outflow ports 133 are arranged between each of the three outflow ports 132, so that the three extrusion hoses 121 are connected to three outflow ports 132 To supply the fresh medicament liquid L from the inside of the storage tank 110 into the doctor chamber 130 on average by supplying the medicinal liquid L from the vicinity of the left and right ends of the doctor chamber 130 and from the center portion, The chemical liquid L that has flowed out from the lead portions 133 is drawn out from the doctor chamber 130.

18 (C), the doctor chamber 130 having the outer frame formed in a substantially rectangular shape along the anilox roll 151 formed to be largely formed and rotated around the rotation axis R0 has an equal interval And an inlet portion 132 connected to the extrusion hose 121 at a plurality of locations on the upper side of the drawing. And a plurality of lead-out portions 133 connected to the lead-in hose 141 are provided at lower portions of the doctor chamber 130 adjacent to the lead-in portions 132, respectively.

18 (C), the chemical liquid L is supplied from the extrusion hose 121 to the plurality of inlet portions 132 arranged along the width direction D of the doctor chamber 130, The chemical liquid L that has flowed from the plurality of lead portions 133 adjacent to the plurality of lead portions 132 is led out from the doctor chamber 130. Therefore, even in this example, fresh medicinal liquid L from the inside of the storage tank 110 can be supplied to the doctor chamber 130 on average and the medicinal liquid L overflowed from the lead- And is drawn out from the doctor chamber 130.

Further, the scope of the present invention is not limited to the above-described embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.

For example, when the tube 133c is not formed in the chemical liquid supply apparatus 100, an air filter is provided on the upper portion of the hole 133b to prevent foreign matter such as paper dust from being mixed into the hole 133b . The hole portion 133b may be formed on the side surface of the body portion 131 if it is above the liquid surface of the chemical liquid L in the storage portion 131a.

≪ Embodiment of flexo 2 roll transfer type >

Here, an example of a two-roll transfer type in the flexo printing method will be described.

As shown in Figs. 11 and 23, the liquid medicine holding portion 53A, which is one of the flexographic printing methods, is provided with a squeegee roll 62A, which is a deep roll, in a rotatable manner in a chemical liquid tank 66A containing a chemical liquid. An anilox roll 63A is rotatably provided in contact with the squeegee roll 62A outside the chemical liquid tank 66A and is in contact with one side of the laminated continuous sheet S2 in contact with the anilox roll 63A. A roll 64A is rotatably provided so that pressure is applied to the laminated continuous sheet S2 together with the elastic roll 65A opposed to the laminated continuous sheet S2.

In this embodiment, the chemical solution shroud 53A is provided on the surface side of the laminated continuous sheet S2 opposed to the roller 54A of the contact embossing means 54 described later and also opposed to the winding drum 56A described above Is located.

As shown in Figs. 11 and 23, the chemical solution shroud 53B, which is the other flexographic printing type, is rotatably provided with a squeegee roll 62B, which is a deep roll, immersed in a chemical solution tank 66B containing a chemical solution. The anilox roll 63B is rotatably disposed outside the chemical tank 66B while being in contact with the squeegee roll 62B and is in contact with the other surface of the laminated continuous sheet S2 in contact with the anilox roll 63B A pressure is applied to the laminated continuous sheet S2 together with the elastic roll 65B opposed to the laminated continuous sheet S2 with the chopped roll 64B being rotatably installed.

In the present embodiment, this chemical solution shroud 53B is located on the other surface side of the laminated continuous sheet S2 which does not face the roller 54A and does not face the winding drum 56A.

A chemical solution is applied from both the chemical solution shroud 53A and the chemical solution shroud 53B to both sides of the laminated continuous sheet S2 while the chemical solution shroud 53A is pressed against the roller 54A by the chemical solution shroud 53A, The chemical liquid can be applied to the laminated continuous sheet S2 from both sides of the laminated continuous sheet S2 while reducing the amount of the coated side of the laminated continuous sheet S2 with respect to the amount of application on the other side by the chemical liquid shell 53B.

Therefore, according to the present embodiment, since the plate is made of resin and elasticity by using the flexo type, even if there is some irregularity in the laminated continuous sheet S2, it can be adjusted by the printing pressure. Therefore, So that the continuous sheet S2 is not easily wrinkled. On the other hand, by using the flexographic printing method, even if the processing speed is high, the application amount can be stabilized and the viscosity of a broad chemical liquid can be stably applied with one roll. Concretely, when the laminated continuous sheet (S2) is conveyed at a speed of 700 m / min or more while applying a chemical liquid to be a chemical liquid at a coating amount of 2.5 g to 5 g / m 2, the laminated continuous sheet (S2) .

≪ Embodiment of Flexo 1 roll transfer type >

In the flexographic printing system, the one-roll transfer type is a mode in which the squeegee rolls 62A and 62B are omitted in the above-described flexographic printing mode. In this case, the anilox rolls 63A and 63B are rotatably installed in the chemical liquid tanks 66A and 66B, respectively. The anilox rolls 63A and 63B may be provided with doctor blades (not shown) for scraping the chemical solution on the surfaces of the anilox rolls 63A and 63B. Such a flexo 1 roll transfer type has an advantage in that maintenance is comparatively easy, and abrasion of blades and foreign matters such as paper powder in the chemical liquid can be easily seen with the naked eye.

(Contact embossing means)

A contact embossing means 54 for imparting contact embossing to the laminated continuous sheet S2 can be formed on the manufacturing equipment X1 of the secondary fabric roll for a tissue paper product.

Here, as shown in FIG. 13, the contact embossing means 54 is made of a metal roll or a supporting roll 54B which is an elastic roll, and a metal-made hard roller 54A having a fine convex portion 54C on its surface, And are rotatably provided on their outer circumferential surfaces while abutting each other. Then, the laminated continuous sheet S2 is sandwiched between the support rolls 54B and the convex portions 54C, which are located at the left and right sides of the laminated continuous sheet S2 in the widthwise center of the tissue paper product, Line contact embossing (CE) is performed on the laminated continuous sheet S2 to prevent delamination along the continuous direction of the laminated continuous sheet S2.

The laminated continuous sheet S2 is wound by the winding means 56 with the surface on the side opposite to the roller 54A for embodying the contact emboss CE as the outer circumferential side.

By providing the contact embossing CE in this way, interlayer delamination of the laminated continuous sheet S2 formed by laminating a plurality of primary continuous sheets (S11 and S12 in the illustrated example) is prevented. It is preferable that the contact embossing (CE) is formed so as to be located on both sides in the width direction of the tissue paper product so that the interlayer peeling at the end of the tissue paper product does not occur easily.

The position of the contact embossing means 54 is not particularly limited but may be a rear end of the chemical liquid applying means 53 and a front end of the slit means 55 or a rear end of the calender means 52, I can think of doing. That is, the rear end of the calender means 52, and the front end of the slit means 55.

When the contact embossing CE is applied to the contact embossing means 54, a contact embossing (CE) is applied within 0.3 to 2.5 seconds, preferably 0.3 to 1.0 seconds after the chemical liquid is applied to the laminated continuous sheet S2 . If the time is less than 0.3 sec, the chemical solution is not sufficiently absorbed to the paper sheet, so that the chemical solution adheres to the support roll 54B or the roller 54A and the contaminant adheres to the support roll 54B or the roller 54A . If it exceeds 2.5 seconds, the laminated continuous sheet (S2) coated with the chemical solution is completely stretched, so that the process wrinkles do not occur easily, and it becomes difficult to obtain a bulky tissue paper product. Further, when the laminated continuous sheet S2 is fully elongated, elongation that can cope with the draw fluctuation is lost, and the tensile strength is lowered due to moisture absorption and absorption.

In this embodiment, in this embodiment, the rollers 54A made of metal and having fine convex portions 54C on the surface thereof are used as the rollers. However, in the laminated continuous sheet S2, the line- For example, instead of the roller 54A, a roller having a fine irregular member on its surface may be used as a roller.

As the means for joining, it is not limited to the above example, and the roller may be a roller having a tip shape of a convex portion of a point shape, a square shape, a rectangle shape, a circle shape or an ellipse shape, or the shape of the tip of the convex portion may be linear, A linear roller or the like may be used as the roller.

On the other hand, the arrangement of the convex portions may be equally spaced, but it may be zigzag-like or not equally spaced, and the convex portions may be arranged in one row to provide continuous contact embossing, I can think. Further, a plurality of contact embossing groups may be provided by arranging a plurality of groups in which the convex portions are arranged so as to closely laminate the contact embossing. The joining step may be performed by other means such as ultrasonic waves in addition to mechanically applying pressure as described above.

A tension control means 57 for controlling the tension of the laminated continuous sheet S2 may be formed between the second chemical solution applying means 53 and the contact embossing means 54 as shown in Fig. The tension control means 57 is formed of a cylindrical roll, and is movable up and down in accordance with the degree of bending of the laminated continuous sheet S2.

It is also proposed to arrange the calender means 52 at the front end of the second chemical liquid application means 53 and at the rear end of the tension control means 57 when the tension control means 57 is formed. In this case, in the calendering means 52 disposed at the rear end of the tension control means 57, the calender roll 52A is moved apart from the receiving roll 52B by a distance equal to or greater than the paper thickness of the laminated continuous sheet S2 It is also proposed to allow the laminated continuous sheet S2 to pass without being subjected to a smoothing process (a manufacturing facility and a manufacturing method of a second-end roll for a second tissue paper product).

(Primary continuous sheet)

The raw pulp of the first continuous sheets (S11, S12) is not particularly limited, and a suitable raw pulp may be selected depending on the use of the tissue paper product. As the raw pulp, for example, wood pulp, non-wood pulp, synthetic pulp, recycled pulp and the like, and more specifically, pulp pulp (GP), stone ground pulp (SGP), refiner ground pulp (RGP), pressurized pulp Mechanical pulp (MP), chemical mechanical pulp (CGP), semi-chemical pulp (SCP), hardwood bleaching kraft (CMP), and the like, such as thermomechanical pulp (TMP), chemical thermomechanical pulp (CTMP), and bleach chemi thermomechanical pulp Chemical pulp (CP) such as kraft pulp (KP), soda pulp (AP), sulfite pulp (SP) and dissolved pulp (DP) such as pulp (LBKP) and softwood bleached kraft pulp (NBKP), nylon, rayon, poly Recycled pulp such as de-ink pulp (DIP), waste pulp (WP), waste pulp (TP), cotton, flax, hemp, jute, manila hemp, Rape pulp, straw pulp, esparto pulp, bar Scotland can be appropriately selected and used for pulp, bamboo pulp, pulp of one or several kinds of accessories such as bridges, etc. pulp, bast pulp such as kenaf pulp.

Particularly, the raw pulp is preferably blended with NBKP and LBKP. (JIS P 8120), NBKP: LBKP = 20: 80 to 80: 20 is preferable. In particular, NBKP (LBKP) and LBKP : LBKP = 30: 70 to 60: 40 is preferable.

The primary continuous sheets S11 and S12 have a basis weight of 10 to 25 g / m2, preferably 12 to 20 g / m2, and more preferably 13 to 16 g / m2 according to JIS P8124. If the basis weight is less than 10 g / m 2, it is preferable from the viewpoint of softness, however, appropriate strength can not be secured. On the other hand, when the basis weight exceeds 25 g / m < 2 >, the tactile sensation deteriorates because it becomes too hard.

The paper thickness (measured with a picocure manufactured by Ozaki Co.) is 80 to 250 占 퐉, preferably 100 to 200 占 퐉, and more preferably 130 to 180 占 퐉 in one ply.

The first continuous sheets S11 and S12 preferably have a crepe ratio of 10 to 30%, more preferably 12 to 25%, and particularly preferably 13 to 20%. If the crepe ratio is less than 10%, it becomes a tissue paper product which is easy to be produced at the time of processing, has little elongation, and has no elasticity. On the other hand, if the crepe ratio exceeds 30%, it is difficult to control the tension of the sheet during processing, and after the production, wrinkles are generated, resulting in an apparently bad tissue paper product.

The first continuous sheets S11 and S12 are formed in such a manner that the longitudinal direction of the dry tensile strength specified in JIS P8113 is 200 to 700 cN / 25 mm, preferably 250 to 600 cN / 25 mm, Preferably 300 to 600 cN / 25 mm, and the transverse direction is 100 to 300 cN / 25 mm, preferably 130 to 270 cN / 25 mm, particularly preferably 150 to 250 cN / 25 mm at 2 plies. If the dry tensile strength of the paper is too low, troubles such as elongation are likely to occur at the time of manufacture and use, and when it is too high, it becomes stiff feel at the time of use.

This force can be adjusted by known methods, for example by adding a dry strength agent to the pulp slurry prior to the dryer part (for example, by adding it to the pulp slurry), or by reducing the freeness of the pulp (e.g., , Or increasing the NBKP compounding ratio (for example, to 50% or more), or the like.

Examples of the dry viscoelastic agent include starch, polyacrylamide, carboxymethylcellulose (CMC) or its salt, carboxymethylcellulose sodium, carboxymethylcellulose calcium, carboxymethylcellulose zinc and the like. As the wet strength agent, a polyamide polyamine epichlorohydrin resin, a urea resin, an acid colloid-melamine resin, a thermally crosslinked PAM and the like can be used. In the case where the wet strength agent is added, the addition amount thereof can be set to about 5 to 20 kg / t in terms of the weight ratio to the pulp slurry. When the drying agent is added to the pulp slurry, the addition amount of the pulp slurry may be about 0.5 to 1.0 kg / t.

[Method for producing secondary fabric roll for tissue paper products]

Next, an example of a method of manufacturing a secondary fabric roll for a tissue paper product according to the present invention will be described. The manufacturing method of the secondary fabric roll for the tissue paper product according to this embodiment can be manufactured, for example, using the above-described manufacturing equipment X1 for the secondary fabric roll for the tissue paper product.

As shown in Fig. 11, in the method of manufacturing a secondary fabric roll for a tissue paper product according to the present invention, the primary continuous rolls (S11 and S12 in the illustrated example), which are unwound from a plurality of primary fabric rolls by the ply means 51 ) Is laminated along the continuous direction to form a laminated continuous sheet S2 (lamination step), the chemical liquid is applied to the laminated continuous sheet S2 by the pair of first liquid chemical liquid spraying means 40 (Second chemical liquid spraying step), and the slit means 55 is used to apply the chemical liquid to the laminated continuous sheet S2 by the pair of second chemical liquid applying means 53, (Slit process) so as to have a product width or a multiple of the product width of the tissue paper product, and then coaxially coats the slit laminated continuous sheet S2 in the slit process to form a product width of the tissue paper product or a product width A plurality of secondary fabric rolls R are wound up by winding means 56 The Castle.

Further, in the method of manufacturing the second raw material roll for tissue paper products according to this embodiment, similarly to the above-described manufacturing equipment (X1) for the second raw material roll for the tissue paper product, in the latter stage of the laminating step, A smoothing step of performing smoothing processing with the pair of calendering means 52 with respect to the smoothing step S2 may be formed. A contact embossing process may be performed in which a line-shaped contact embossing is performed on the laminated continuous sheet S2 at the front end of the slit process at the rear end of the chemical solution applying process to prevent delamination by the contact embossing means 54. [

In the manufacturing equipment or the manufacturing method of the secondary raw material roll for tissue paper products according to the present embodiment, the processing speed is 100 to 1100 m / min, preferably 350 to 1050 m / min, and more preferably 450 to 1000 m / min . If the rate is less than 100 m / min, the productivity is low, and if it exceeds 1100 m / min, the frequency of the laminated continuous sheet (S2) becomes high and the chemical liquid application process becomes unstable due to unstable chemical liquid transfer from the chill plate roll or the anilox roll .

Although the flexographic printing method has been mainly described in the above example, the gravure printing method can also be adopted as described above. In the gravure printing method, for example, as shown in FIG. 32, the dip roll 71 lifts a predetermined amount of the chemical liquid from the chemical liquid tray 70, and the chemical liquid remaining in the cell of the dip roll 71 is transferred to the gravure roll 72. Subsequently, the chemical liquid transferred to the gravure roll 72 is simultaneously transferred to the surface of the laminated sheet S2 as a backup of the pressure drum 74 while being scratched by the scraping blade 73. The density of the halftone dots of the gravure roll 72, and the like can be appropriately selected.

[Multi-stand type interfolder]

The secondary fabric roll (R) manufactured by the manufacturing facility and the manufacturing method of the secondary fabric roll for the tissue paper product is fed from the secondary fabric roll (R), which is set on a multi- And folded and folded to produce a tissue paper bundle. Hereinafter, an example of the multi-stand type inter-folder will be described.

2 and 3 show an example of a multi-stand type interfolder. In the drawing, reference numeral 2 denotes secondary fabric rolls (R, R, ...) set on a secondary fabric roll supporting portion (not shown) of the multi-stand type interfolder 1. [ These secondary fabric rolls R, R, ... are set side by side in a direction in which the necessary number is orthogonal to the urban plane (horizontal direction in Fig. 2, front-back direction in Fig. 3). Each of the secondary fabric rolls R has a slit in the width of the tissue paper product as described above for the manufacturing equipment and manufacturing method of the secondary fabric roll for the tissue paper product, so that the tissue paper product has a multiple width, As shown in FIG.

The continuous strip type secondary continuous sheets 3A and 3B unwound from the secondary fabric roll R are guided by guide means such as guide rollers G1 and G1 and conveyed to the folding mechanism section 20. [ As shown in Fig. 4, the folding mechanism section 20 is provided with a folding plate group 21 formed by arranging a plurality of folding plates P, P ... necessary. Guide rollers G2 and G2 and guide rod members G3 and G3 for guiding a pair of successive secondary continuous sheets 3A and 3B are provided in place at the respective folding plates P respectively. And a conveyor 22 for receiving and conveying the laminated belt 30 stacked while being folded is provided below the folding plates P, P ....

A folding mechanism using these kinds of folding plates (P, P ...) is, for example, a mechanism known from US Pat. No. 4,052048. As shown in Fig. 5, this type of folding mechanism is constituted by folding successive secondary continuous sheets 3A, 3B, ... in a Z-shape, and connecting adjacent secondary continuous sheets 3A, 3B, And the side end portions of the side walls are stacked.

Figs. 7 to 10 show details of the folding mechanism section 20, particularly the fold plate P, in detail. In the folding mechanism section 20, a pair of continuous secondary continuous sheets 3A and 3B are guided to the respective folding plates P. At this time, the continuous secondary continuous sheets 3A and 3B are guided by moving the position so that the side end portions do not overlap each other by the guide rod members G3 and G3.

A continuous secondary continuous sheet 3A is referred to as a continuous secondary continuous sheet which overlaps the lower side at the time when it is guided to the folding plate P and a continuous secondary continuous sheet which is superimposed on the upper side is referred to as a second continuous , The continuous secondary continuous sheets 3A and 3B are arranged in such a manner that the continuous secondary continuous sheets 3A and the continuous secondary continuous sheets 3A, The side end portion e1 which does not overlap with the secondary continuous sheet 3B is folded back to the upper side of the second continuous secondary continuous sheet 3B by the side plate P1 of the folding plate P, The side end portion e2 which does not overlap with the first continuous secondary continuous sheet 3A in the second continuous secondary continuous sheet 3B as shown in Fig.9 is inserted into the slit P2 of the foldable sheet P, And is folded back downward as it is pulled under the folding plate P from below.
