Abstract

PURPOSE:To produce multi-color laminated tissue papers on a narrow floor area by once parallelly running many belt-like papers on lanes parallel to a folding line in group, selecting their color and separating the papers at a predetermined position, and feeding them to a folding machine. CONSTITUTION:Belt-like papers w1..., b1..., p1..., g1... drawn out of white, blue, purple, and green wound original papers W, B, P, G are parallelly run in group on lanes A1, A2 arranged in parallel with a folding line L mostly via direction converters 1 respectively. Then, combination of colors is selected, and the papers are fed to respective folding machines M1-M12 via corresponding separation positions S. For example, the folding machine M7 laminates the tissue paper combined with belt-like papers b3, w3 in multi-colors. Accordingly, troubles due to the crossover of belt-like papers are eliminated, and in addition, multi-color laminated tissue papers can be easily produced on a narrow floor area.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides multicolor laminated tissue paper that is sequentially pulled out and stacked vertically adjacently, with different colors, and then folded and stacked. The present invention relates to a method for manufacturing multicolor laminated tissue paper that can be manufactured by feeding strips of paper to a folding machine while effectively utilizing a narrow space.

In recent years, daily life products have become abundant, and laminated tissue paper stored in a clean container that can be pulled out one after another has become commonplace.

In order to manufacture such laminated tissue paper of the sequential drawer type, the following steps are required. It's according to the law.

That is, as is known from, for example, Japanese Patent Laid-Open No. 52-123715 and Japanese Patent Publication No. 55-15385, a large number of folding machines arranged from upstream to downstream on a normally straight folding line are sequentially For example, by feeding one set of two strips of paper strips each having the width of the tissue in a state that is shifted by half the width of the tissue, and feeding each set at the same speed, each folding machine may Each strip of 11 strips of paper is folded to half the width of the tissue and stacked sequentially from bottom to top. At this time, the openings formed by folding each strip of paper to half the width alternately face each other, and each strip of paper is folded to half the width of the tissue. The above-mentioned half-widths of the paper strips are inserted into the openings of the paper strips adjacent above and below, and are folded and stacked one on top of the other in a sequential pull-out style (in the present invention, the state of being folded and stacked in this way is simply referred to as "stacked"). The laminate thus obtained is cut into a predetermined length to produce laminated tissue paper for insertion into containers. Laminated tissue paper usually has a length of 100
- 300 sheets of tissue paper (in this invention, even two sheets of tissue paper are referred to as one sheet) are stacked, so to manufacture this, strips of paper with the same number of tissue widths are placed on the folding line. supply it. In order to simplify the preparation process of rolled paper strips and the equipment for supplying them to the folding line, the following methods have recently been used to supply paper strips with multiple tissue widths to the folding line. is taken. In other words, a roll base paper is prepared in which multiple strips (2 to 6 strips or more) of tissue-width paper strips are wound around a single long core, and one roll base paper is wrapped around a tissue-width strip of paper. For all the roll sheets, set the roll paper almost parallel to the folding line at a position corresponding to the range of the folding machine responsible for supplying paper, and remove multiple extra strips of paper from the roll paper. If the multiple extra strips of paper on each roll of paper are multiple strips of paper that have been slit to the width of the tissue, then they can be pulled out from the roll of paper. If it is a wide paper with multiple widths, slit it to the width of the tissue while pulling it out.In this way, it forms multiple strips of paper as a whole and pulls it out in a direction almost perpendicular to the folding line. Multiple strips of paper from each roll are non-electronically fed to the folding machine over a short distance.If this method of feeding strips is adopted, multiple strips of paper from each roll are fed approximately parallel to the long folding line. Even if a large number of strips of paper are set and fed to the folding line, all the strips from each roll of paper are folded by the VI folding machine located at the position corresponding to each roll of paper.
Since the tatami is reeded, strips of paper from different roll sheets will not intertwine. Therefore, when manufacturing laminated tissue vapor of a single color, such as white, it is sufficient that all of the multiple strips of paper fed to the folding line have that single color. By making all the strips of paper from the roll paper the same color, it was possible to produce laminated tissue paper of a single color without any problems.

The demand for laminated tissue paper in a single color has been established, but in recent years, daily life products have become more diverse and abundant, and laminated tissue paper is also available in various colors. The demand for multi-colored laminated tissue paper with folded layers is increasing. Such multi-colored laminated tissue paper is such that the color arrangement is such that when it is pulled out sequentially, tissue papers of different colors are taken out one after another, that is, at least tissue papers of the same color are consecutively placed one above the other. There has been a demand for multicolored laminated tissue paper in which tissue papers of as many different colors as possible are laminated without being laminated.

However, such multi-colored laminated tissue paper cannot be produced by the method for manufacturing laminated tissue paper described above! l
For manufacturing, it is necessary to make at least two vertically adjacent strips of paper folded by each folding machine different in color. Accordingly, if the plurality of extra strips for each web are all of the same color, the adjacent strips before and after being folded by the folding machine are always one from two different rolls. The strips must be supplied in strips, and the strips of the same color from one web are distributed over a wider area than when producing single-color laminated tissue paper. Since the strips are distributed and supplied to the folding machines, it is inevitable that many strips of paper will intertwine in an area that includes a plurality of roll sheets and folding lines.

Conventionally, like this? There has been no effective means for how to skillfully handle the interlacing of these strips of paper in as little space as possible so as not to cause manufacturing troubles due to the supply of TF-shaped paper. In addition, if a plurality of paper strips of the roll base paper are cut in advance to the width of the tissue, several strips of 7'C'4 If you prepare and use each roll of paper that changes colors sequentially to match the multicolored arrangement of the paper, you will avoid problems caused by crossing when feeding multiple strips of multicolored strips of paper to the folding line. However, for each roll paper, roll paper strips of various colors that are not necessarily in the same color order without making a mistake, or use a roll paper in which only one strip paper is wound, and each It is necessary to set the roll sheets in a predetermined order, and such an operation significantly reduces work efficiency and often causes errors in color arrangement. Therefore, in the past, multicolor laminated tissue paper has only been manufactured with a very limited number and arrangement of colors, as will be explained below.

One of them is tissue paper of only two colors stacked alternately, which means that each roll of paper has a plurality of extra strips of the same color, and the minimum number of multi-colored tissue papers is 2.
The paper was manufactured by preparing different colors and setting roll paper of each color alternately to minimize the overlap of the paper strips, although this caused some trouble. The other type is one in which multi-colored tissue paper sheets are sequentially stacked one by one, but as explained above, each roll base paper uses a roll paper in which only one strip of paper is wound. It was manufactured by
Extremely bad for work efficiency. Still another type is one in which several sheets of tissue paper of each color are rolled in succession, although the number of colors is large, and each roll of paper has multiple strips of the same color. It is manufactured by using a roll of paper in multiple colors from which it is drawn. However, the multicolored laminated tissue paper sheets with little variation in the number of colors and arrangement of colors as described above cannot satisfy the recent demands for diversification of daily necessities; However, there are problems with work efficiency and manufacturing costs.

The present inventors set a plurality of roll sheets of various colors from which multiple strips of paper strips of the same color are pulled out, and each of the multiple strips of paper from these roll sheets is placed in a predetermined folding machine. To provide a method for manufacturing multi-colored laminated tissue paper sheets, which can be supplied in a narrow space and can be made as specified without restricting the number or arrangement of colors, without causing trouble due to the intersection of paper sheets. As a result of research on the purpose, it was found that the paper strips from each web are once run on one lane on a horizontal projection plane parallel to the folding line, and the selected paper strips are separated from the group at an appropriate position. The present invention was completed by discovering that the purpose could be achieved by separating and supplying the product to the target folding machine.

That is, in the present invention, a plurality of roll sheets of two or more colors are prepared from which a plurality of strips of paper strips of the same tissue width are drawn out, and a plurality of strips of strip paper are drawn from each of the plurality of strips of paper strips. While pulling out in parallel, the folding machine is folded from the upstream side to the downstream side on the folding line without any misalignment from the upstream side to the downstream side. The above-mentioned strips of paper are sequentially supplied so as to be stacked, alternately shifted left and right by half the width of the tissue, and as they pass through the folding machine, they are folded to half the width of the tissue and are stacked one on top of the other from the bottom to the top. The paper strips were folded and stacked on one folding line in a sequential draw-out manner with the openings of the paper strips facing each other alternately and each of the half widths of each paper strip being inserted into the openings of the paper strips adjacent above and below. When obtaining a laminate and then cutting the laminate into a predetermined length to produce a laminated tissue bag for charging into containers, all or most of the large number of strips of paper drawn from each roll base paper are All or most of the paper strips are arranged in the same lane on a horizontal projection plane substantially parallel to the folding line and run as one group in the same direction substantially parallel to the folding line, and all or most of the paper strips are made to run as one group. ):
By performing an operation to separate each sheet from the group at a predetermined position, and feeding all the strips pulled out from all the prepared roll sheets to the folding machine by selecting their respective colors, This invention relates to a method for manufacturing multicolor laminated tissue paper, characterized in that the paper strips stacked adjacent to each other on the folding line are made to have different colors, and the paper strips are successively folded and stacked in a pull-out manner. .

Hereinafter, the method of the present invention will be explained in detail with reference to the drawings.

FIG. 1 is an explanatory plan view showing the flow of a part of the paper strip in one embodiment of the method of the present invention by lines on a horizontal projection plane, and FIGS. 2 and 6 show the state of the direction of the paper strip being changed by the direction changing device, respectively. Figure 4 (a) and (b) are respectively elevational views showing how the running height of the paper strip is adjusted by the rolls, and Figure 5 shows the position from the running group in Figure 1. A side explanatory view showing a state in which a predetermined paper strip is separated in S1, and FIG. 6 is a partial illustration of a state in which one set of two strips of paper is sequentially supplied to the folding machine to form a stack in FIG. 1. 7, FIG. 8, FIG. 9, and FIG. 10 are plan view diagrams showing the structure of FIG. 6 along lines AA and C-C in FIG. 6, respectively.

FIG. 11 is an enlarged explanatory view of each end face taken along line D-D and line E-110, FIG. Figure 11 is a side explanatory diagram of the flow of paper strips on the folding line side from the lane as seen from the folding line side.
FIG. 2 is an explanatory cross-sectional view showing the stacked state of paper strips in the laminate obtained in the example of FIG. 1. FIG.

In the present invention, first, a predetermined number of roll sheets from which a plurality of strips of paper of the same color are pulled out is set in consideration of the color arrangement. In Figure 1, six strips of paper of the same color are pulled out, and each of the four colors of roll paper W, B, white, blue, purple, and green is pulled out.
- P and G are set repeatedly one roll each from the end (in FIG. 1, the second and subsequent times are omitted). Depending on the set direction of the roll paper, even if the direction of each strip paper W1+b, etc. of trench 1 pulled out from each roll paper W2B, etc. is not perpendicular to the folding line L, the running direction of the strip paper may be changed by a direction changing rod or the like. However, when each roll paper W2B etc. is set on a straight line parallel to the folding line L as shown in Fig. 1, the pulling direction of each strip paper W+ + BL etc. is perpendicular to the folding line L. Then, one sheet of each strip w1. It is advantageous to have many common parts in the drive equipment for forcibly sending out b1 etc.

There are many folding machines, including folding machines that feed strips of paper in sets of two strips and folding machines that feed strips of paper one strip at a time.
Although the explanation will be given by taking the folding machine of Person J as an example, the gist of the present invention does not change even if the latter folding machine is used in the method of the present invention. Folding machines such as MI +M2 are supplied with one set of two strips of paper for each folding machine, so as shown in Figure 1,
The fact that they are arranged on the folding line L corresponding to the position of each two strips of paper on each set of roll sheets is
This is preferable because it simplifies the flow of supplying paper strips and reduces the overall space. However, this is not necessarily necessary, and each folding machine may be placed at any position on the folding line L.

The embodiment shown in Fig. 1 is a multicolored laminated tissue paper in which the colors of the tissue paper stacked in instant contact with each other are white! This paper is intended to produce a multicolor laminated tissue paper in which tissue papers of four colors, blue, purple, and green, are stacked one by one of each color in a sequentially removable manner from the bottom to the top. Thereupon, the set white winding base paper W, blue winding base paper B, purple winding base paper P, and green winding base paper G are set.
The strips of paper "l + bl, etc. of each color are pulled out from each of them, and after passing through each route, the paper strips of white and blue are finally delivered to the first folding machine M1 from the upstream side of the folding line L. A set of 2 strips of strip paper is used, and a set of 2 strips of strip paper each of purple and green is placed in the second folding machine M2. The materials are supplied in an overlapping state shifted by half the width, and this is repeated thereafter.The most important feature of the method of the present invention lies in the method of supply described below.

First, in FIG. 1, a large number of strips of paper W1~"6+bI~b6 are pulled out from each roll paper W, B, P, and G.
Ip1 to p6 r g+ to g6, etc., all or most of them are once run in a direction approximately parallel to the folding line L (
(Hereinafter, such running may be referred to as parallel running.)

This direction is the same as the direction from upstream to downstream of the folding line L (arrow Depending on the relationship between the seven-fold position of the roll paper and the arrangement position of the folding machine, there are cases where both directions are taken, and cases where either one direction is taken. And in order.

In contrast, the strips of paper running in parallel in one or both directions are positioned in the same lane on a horizontal projection plane substantially parallel to the folding line L in each direction, and run as a group. Therefore, since each strip of paper constituting one group runs in the same direction and at the same speed, even if the strips of paper constituting the group overlap vertically to further reduce the required space, this will not affect the running. Of course, they may overlap with a gap provided therebetween. When there are two groups, each group runs on one lane on the horizontal projection plane, but even if the lanes each group runs on are lanes A1 and A2 located at the horizontal projection plane stop as shown in Figure 1. However, they may be on the same lane on the horizontal projection plane, in which case the two groups will travel at different heights. Moreover, one lane may be located at approximately the same position as the folding line L, as will be described later. In this way, it is not necessarily necessary for all strips of paper to run in parallel, but it is necessary to adjust the positional relationship between each roll paper W2B, etc. and each folding machine M, M2, etc., and the number and arrangement of tissue paper colors. Due to this, parallel running may not be necessary for some paper strips. For example, in FIG. In this way, the ratio of paper strips that do not require parallel running to the total paper strips varies depending on the mutual positional relationship between the roll paper and the folding machine, the color, and the arrangement. The maximum is 50%.

Whether each 7F-shaped paper running in parallel is directed in the forward direction or in the reverse direction depends on the positional relationship between the position when the strip paper is pulled out from the roll paper and the position of the folding machine to which it is supplied. In FIG. 1, for example, due to the relationship between the folding machine M1 and the position of the paper strip b1 supplied thereto when it is pulled out from the roll paper B, the paper strip b1 runs in the opposite direction (in the direction of the arrow 2) on the lane A2. Furthermore, for example, due to the relationship between the folding machine M5 and the position of the paper strip W2 supplied thereto when it is pulled out from the roll paper W, the paper strip W2 is forced to run in the forward direction (direction of arrow Y) on the lane A1. be.

In this way, in Figure 1, "2+wro, W4, W

Each strip of paper gx T g4 + gs is made into a part of another part and is made to run parallel to each other in opposite directions on lane A2 (in the present invention, a part is defined as a part of paper strips running parallel to each other in the same direction). [This does not mean that the paper strips are formed at the same time, but rather that the paper strips are added or separated one strip from the middle.] In this way, each strip of paper pulled out from the roll paper is placed on lane A1 or A2. To run in parallel, as shown in Figs. 2 and 6, a direction changing tool 1 (shown as a rod-shaped member in the figure, but it may also be an edge of a plate, etc., the same applies hereinafter).
All you have to do is change direction in each direction. What is the running surface of the paper strip when it runs horizontally? When it becomes necessary to adjust A, please refer to Figure 4 A] and (
The simplicity can be easily adjusted by changing the direction twice without changing the direction on the horizontal projection plane using the roll 2 as in b).

In this way, the sheets of paper drawn out from each roll of paper and made to run in parallel as a part are separated from the group at a predetermined position for each strip of paper and fed to a predetermined folding machine. do. In this case, there are three different ways to separate and supply the paper strip from the group in a folded manner.

The first aspect is a separation and feeding method in which the roll sheets W, B, etc. are run in parallel at a position between the folding line L on the horizontal projection plane as shown in FIG. The strip paper can be freely selected and implemented. That is, all or most of the many strips of paper pulled out from each roll base paper are positioned on the same lane on a horizontal projection plane approximately parallel to the fold line L between the roll base paper and the folding line L. All or most of the paper strips are separated from the group at a predetermined position. The direction is changed perpendicularly to the folding line L so that it intersects the folding line L three-dimensionally, and then the direction is changed again so as to be approximately 18' perpendicular to the folding line L. supply it. An example of a specific method for changing the direction of a group of valleys 11y-shaped papers running in parallel at a predetermined position by a distance of ν+1t at a substantially right angle to V will be described with reference to the case shown in FIG. For example, to separate the paper strip b6 from the roll sheet B running in parallel in the forward direction on the lane A1 from the group consisting of other paper strips "4+" Arb & rb6 at position S1, and change the direction at right angles. As shown in FIG. 5, first, two rolls 2 are used as a set in the same manner as in FIG.
Provide a gap necessary for changing the direction between the paper strip b3 and the vertically adjacent paper strip b5°W6 (or the paper strip b6
It goes without saying that this operation is unnecessary if there is already a gap above and below that is necessary for changing direction]. Then, the direction changing tool 1 is used in the same manner as in FIG. 2 or 6 to change the direction at right angles. The direction of the strip of paper ba is changed in this way [at the position where it three-dimensionally intersects with the folding line L, the direction of the strip of paper ba is changed so that it almost coincides with the folding line L on the horizontal projection plane. It is supplied to the folding machine M7 together with W6.

Other aspects of the method for separately supplying the paper strips running in parallel to the folding machine will be explained later in other embodiments.

In the present invention, as described above, all or most of the strip of paper from the roll paper is once run in parallel, then the direction is changed at right angles at an appropriate position, and the paper is fed to the folding machine. Some paper strips, such as paper strips Wj+W5 in Figure 1, are folded directly to the folding line L without running in parallel.
, and supply it near the upper folding machine. All the strips of paper W+ + 1)+ +pi +g+ pulled out from all the roll sheets W, B, etc. prepared in this way
A set of two strips of paper are sequentially supplied from the upstream side to each of the folding machines placed on the folding line L, shifted by half the tissue width, and then pulled out sequentially on the folding line L. In this case, the color of the paper strips to be fed to the folding machine is selected in relation to the order of arrangement on the folding line of the folding machine as described above. This allows the strips of paper that are stacked vertically adjacent to each other in the laminate to have different colors. Specifically, one set of two strips of paper fed to one folding machine are made to have different colors, and at the same time,
Of the two paper strips supplied to each of the two folding machines located adjacent to each other on the folding line L, the paper strip that is folded upward by the folding machine located on the upstream side is This makes the colors of the paper strips folded downward by the folding machine located downstream different from each other. Four layers of half-width paper strips are folded in half width so that the openings face each other, and the half-width of one paper strip is inserted into the opening of the other paper strip. The first and sixth positions from the top are called upper,
The second position from the top and the lowest position are called the lower part. Various known folding machines can be used for folding paper in a sequential pull-out manner, and which one of the two strips of paper supplied in a set can be folded upward or downward. (However, as mentioned above, in addition to the above-mentioned folding machine, a folding machine that feeds strips of paper one by one can also be used in the method of the present invention).

Next, by selecting the color of the paper strips as described above and supplying them to the folding machine, the colors between the paper strips stacked adjacent to each other on the folding line L are made different, and the paper strips are sequentially taken out. The state in which the layers are stacked will be explained using a part of the embodiment shown in FIG. 1 as an example. In the embodiment of FIG.
, the folding machine M1 has a white paper strip W1 and a blue paper strip b1.
and the folding machine M adjacent to the reed folding machine M1.
By selecting and supplying the purple paper strip p1 and the green paper strip g1 to the paper sheet 2, the paper strips p1 and g1 are sequentially stacked in multiple colors as shown in FIG. That is, the paper strips W1 and bl, which have traveled at right angles toward the folding line L, reach the folding line L and are changed direction toward the folding machine M1.
Immediately before the paper folding machine M1, the paper strips W and bl are in a state where the top and bottom are bent, respectively, and are shifted by half the width, as shown in FIG. The paperboard and bl are each folded 1 and connected upwardly and downwardly, and in this stacked state travels along the folding line L and passes through the next folding machine M2. In the folding machine M2, the paper strips p1 and g+, which have run perpendicularly to the folding line L and have been changed in direction, are disposed in front of the folding machine M2 in the same manner as in the case of the paper strips W1 and bl, as shown in FIG. When they pass through the folding machine M2, the paper strips p1 and 61 are folded downward and upward, respectively, as shown in FIG. The half-width of the paper strip p1, which is placed vertically on top of the laminate and below, is inserted into the opening of the paper strip b1, which is a laminate that has traveled from the upstream side and is folded upward and stacked one above the other. .

The multicolored laminate obtained by sequentially feeding all the paper strips to the folding machine in this way is successively folded and stacked in a pull-out manner, and each strip of paper that is stacked adjacent to each other is All colors in between are different from each other. In Fig. 6, strips of paper of all four colors are supplied one by one and passed through one cycle, but instead of passing the colors through one cycle, for example, instead of paper strip p1 in folding machine IA2, band paper W
Even if 2 is supplied, the colors between the strips of paper that are folded and stacked one on top of the other by the folding machines M1 and M2 and stacked adjacent to each other will all be of different fc colors. be.

In addition, in Fig. 6, folding machine M1 is shown to make the drawing easier to read.
Although the paper strips b1 and pl are shown separated from each other by increasing the distance between B1 and M2, in many cases, each strip of paper on the folding line L is fed to the folding machine located below. Since this is done from above or diagonally above, there is no need to separate the strip of paper b1 from the strip. In addition, it has traveled at right angles toward the folding line L; the point at which the single-tipped paper reaches the folding line L can be located upstream or downstream of the folding machine to which it is supplied, as it is free. Even if it is located on the downstream side unlike in FIG. 6, it can be guided while changing direction along the vertical plane including the folding line L and supplied to the folding machine from the upstream side.

Next, in the method of the present invention, all or most of the many strips of paper pulled out from each roll of paper are made to travel in one group on the same lane in the same direction that is substantially parallel to the folding line L, so that each strip of paper is A second mode in which each sheet is separated from the group at a predetermined position and then supplied to the folding machine will be described. In this second aspect, the separation operation is performed only in one direction substantially parallel to the folding line L along which the strip of paper runs parallel to the folding line L, with the lane in that direction being placed at substantially the same position as the folding line L on the horizontal projection plane; By sequentially changing the direction of the paper strips running in a group on the lane downward at a predetermined position starting from the lowest layer of paper strips in the core, the paper strips from the group are separated and folded. When there is a group to be fed to the folding machine and run in the other direction on the lane between the winding base paper and the folding line L, the separate feeding of the strips from the group to the folding machine is carried out in accordance with the above-mentioned method, and in many cases. In this case, some of the strips are fed directly from the web to the folding line L without running in parallel. All the strips from all the webs prepared in this way are folded. In order to sequentially supply the paper to the folding machine, the selection of the color of the paper strips is the same as in the first embodiment, but in this second embodiment, the color of the paper strips is almost the same as the folding line L on the horizontal projection plane. The color of the paper strips in the group to be run on the lane to be set is determined by considering the order in which the strips are stacked so that the paper strips in the group can be sequentially fed to the folding machine starting from the lowest layer of the paper strips while running on the lane. A specific example where it is necessary to select papers and form groups will be explained in the embodiment of the sixth aspect belonging to the second aspect.

The sixth aspect is based on the second aspect, that is, an aspect in which, for only one direction substantially parallel to the folding line L along which the paper strip runs parallel, the lane in that direction is set at approximately the same position as the folding line L on the horizontal projection plane. In order to run most of the paper strips pulled out from each roll paper in parallel, all of the paper strips to be made to run in parallel are placed on a lane set at approximately the same position as the folding line on the horizontal projection plane. This is a case where the vehicle is made to run in only one direction. In this sixth mode, the paper strips of the lowest Samurai in the group running in parallel on the lane are fed to the i-tatami machine by sequentially changing direction downward, and some of the strips that are not running parallel are rolled up. The roll paper is directly brought to the folding line L and supplied to the folding machine, and all the strips pulled out from all the roll papers prepared in this way are each selected in its color and fed to the folding machine. However, in this case, it is necessary to select the color of the paper strips and select the color of the paper strips in the order in which they overlap so that the group running in parallel on the lane can be sequentially fed to the folding machine starting from the bottom layer of the group. is the same as the second embodiment.

Next, an example of the sixth aspect will be described. As shown in Fig. 11, using roll sheets R, B, and G of six colors of red, blue, and green (which can be carried out in exactly the same way for four or more colors), follow the flow of the folding line L. Correspondingly, four strips of paper strips are drawn out as the strips of paper that are set and sorted to the first position, and strips of six strips each are drawn as the strips of paper that are sected from the second position onwards. Using the roll paper that is pulled out, fold the paper in the order of red, blue, and green.
set parallel to. Each strip of paper 'I+bj+g++'5, etc. is pulled out in a direction perpendicular to the folding line L from each of the roll sheets R, B, and G. Among these paper strips, the red strip paper '+ + '2 + r3 + '4, drawn from the first roll paper R, is the paper roll 13J.

In order to make the drawing easier to read, the folding line L and lane A are spaced apart from each other on the horizontal projection plane in Figure 1]. They are stacked one on top of the other to form a group and run in parallel. In this group, each of the above-mentioned strips of paper is sequentially stacked upward with the strip of paper rl being the bottom layer, and the 12th

As shown in Fig. 11, on the folding line L, from upstream to downstream in the flow direction of the laminate (arrow X direction), folding machines Ml+M2, etc. are installed for each two strips of paper on each set of roll sheets. They are arranged sequentially in accordance with their positions. Then, in the folding machine M1, the strip of paper b1 that has directly reached the folding line L from the roll paper B and the strip of paper b1 that has been run parallel to the lane A as the lowest layer of the group as shown in FIG. 12 is shown in FIG. The strip of paper r whose direction is changed downward by the opening at the separation position S2 in the middle.
1. In this way, for each folding machine after folding machine M2, the strip of paper forming the lowest layer of the group is separated downward at each separation position S of lane A, and the paper is rolled up at each location. A set of two strips of paper is supplied together with each strip of paper directly from the base paper to the folding line L. The stacked state of each strip of paper in the laminate thus obtained is as shown in FIG. 13, and when the tissue paper is rolled out and pulled out one after another, tissue papers of different colors always come in succession. The operation of separating the strip of paper at a predetermined position from the group running in parallel on lane A as described above is as shown in FIG. Therefore, even if all the paper strips constituting group f run in close contact, there is no need to create a gap as shown in Fig. 5, and the number of paternal conversions can be reduced, making it possible to perform separation operations. Alternatively, it is extremely simple as a separation device.

As described above, as can be seen in any of the embodiments of the method of the present invention, there is no trouble at all caused by complicated intersections in the running of a large number of strips of paper from the roll paper to the folding line, and each roll paper can be set at a short distance from the folding line, making it possible to carry out manufacturing in a narrow space. In each of the above-mentioned embodiments, each roll sheet is placed at a position substantially opposite to the folding line, but this is not necessarily necessary in the method of the present invention, and depending on the shape of the floor surface, the winding base paper is placed at a position substantially opposite to the folding line. It is also possible to move parallel to the row in which the roll sheets are set, and for example, even if the roll sheets are arranged as shown in FIG.

As described above, in the method of the present invention, all or most of a large number of strips of paper drawn from a roll of paper are once folded and run parallel in a group on lanes parallel to a folding line, and each strip of paper is separated from the group at a predetermined position. Then, by selecting the color of all the strips drawn from all the prepared roll sheets and feeding them to the folding machine, the multicolor laminated tissue paper, in which tissue paper of different colors is sequentially drawn, can be made into a multicolor laminated tissue paper of that color. It allows for a rich variety of seeds, a free arrangement of colors, no troubles caused by intersecting strips of paper, and allows for production even in a small floor space.Also, with only one lane, it can be placed almost at the same position as the folding line. When used, there is a certain arrangement which simplifies the operation of separating the paper strips from the group and greatly facilitates the production of multicolored laminated tissue paper.
