Next, the manufacture method of cleaning toilet paper 1 of the present embodiment is described.
The cleaning toilet paper 1 of present embodiment is manufactured by a series of manufacture method, and this manufacture method comprises: embossing manufacturing procedure (S1), implements the embossing with cutting part to the sheet 3 through stacked processing; With finishing step (S2), implement folding processing and fold, coating liquid, packs.
First, Fig. 3 is used to be described in detail to embossing manufacturing procedure (S1).Should illustrate, using pull-out through the direction of the sheet 3 of stacked processing as X-direction, using sheet on the surface with the orthogonal direction, direction of pull-out sheet as Y-direction, the direction orthogonal with sheet surface (XY plane) is described as Z-direction.
In embossing manufacturing procedure (S1), as shown in Figure 3, embossing processing unit (plant) 100 is utilized to carry out embossing processing to the sheet 3 through stacked processing pulled out from the winding roll 2 through stacked processing.
Embossing processing unit (plant) 100 utilizes upside knurling rolls 10 and downside knurling rolls 20 to form the device with the embossing e1 of cutting part 4.Upside knurling rolls 10 are separately positioned on opposite position with downside knurling rolls 20, and roller surface has identical relief pattern.And the protuberance 11 on upside knurling rolls 10 surface and the protuberance 21 on downside knurling rolls 20 surface in the mode do not overlapped each other on the opportunity of implementing embossing processing, protuberance are in staggered configuration by XY direction as described later.
Use an example of the relief pattern on the surface of knurling rolls 10 on the upside of Fig. 4 (a), (b), (c) explanation.Here, as long as the sheet of the sheet more than 32 layers through stacked processing of processing to be embossed, the number of plies can suitably change, and in the following description, is described for the situation of 2 layers.
As shown in an example of Fig. 4 (a), the cross section that the surface of upside knurling rolls 10 is provided with XY direction is hexagonal protuberance 11.This hexagonal shape becomes following hexagon: each hexagonal interior angle 1 is such as 95 ~ 175 degree and is that line is symmetrical with respect to the straight line parallel with Y-direction at center.Here, 2 limits parallel with Y-direction length d1 is separately such as 0.5 ~ 2.5mm, the distance d2 between 2 limits is such as 0.5 ~ 2.5mm.The protuberance 11 being arranged at roller surface is arranged in the mode vacating about 1 protuberance degree interval in the Y direction, and these row and same row are arranged in the mode vacating about 1.5 protuberance degree and the interval of vacating about 0.5 protuberance degree in the Y direction in X-direction.Then, repeat to arrange this 2 row, form the protuberance pattern on roller surface.
In addition, for the cross section of the protuberance 11 on knurling rolls surface, as shown in Fig. 4 (b), the cross section in XZ direction becomes the rectangle that respective angle [alpha] 2 is such as 90 degree, height h1 is such as 1.0 ~ 2.0mm.In addition, as shown in Fig. 4 (C), 2 angle α 3 that the cross section in YZ direction becomes upper bottom side are such as 106 degree, height h1 is such as the trapezoidal of 1.0 ~ 2.0mm.
As shown in Figure 3, upside knurling rolls 10 and downside knurling rolls 20 are arranged in the opposite position of Z-direction, and configure as follows: respective protuberance not overlapping (reference Fig. 5) when upside knurling rolls 10 are overlapping with downside knurling rolls 20.Specifically, as shown in the enlarged drawing of Fig. 5 in Fig. 6, the protuberance 11 of upside knurling rolls 10 is such as 0.1 ~ 0.5mm with the protuberance 21 of downside knurling rolls 20 at the distance s1 of X-direction, and dislocation d3 is in the Y direction such as 0.1 ~ 2.0mm, with 2 limits of Y-direction respectively arranged in parallel mode configure.And then, become cutting position 5 near the side of the Y-direction that the protuberance 11 of upside knurling rolls 10 is relative with the protuberance 21 of downside knurling rolls 20.
The protuberance 11 of the upside knurling rolls 10 in cutting position 5 and the protuberance of downside knurling rolls 20 overlapping d4 is in the Y direction such as 0.4 ~ 2.4mm.Should illustrate, the protuberance of upside knurling rolls 10 11 is such as 0.1 ~ 0.5mm with the protuberance 21 of downside knurling rolls 20 at the distance s1 of X-direction as mentioned above, but as described later, as long as sandwich sheet and the distance utilizing shearing force to make sheet break then can suitably change.
As shown in Figure 7, the protuberance 11 of upside knurling rolls 10 and the protuberance 21 of downside knurling rolls 20 become the formation that can sandwich sheet between the side of the relative Y-direction of respective protuberance.And, the cutting part 4 produced when implementing embossing is that following formation is annoying: during with knurling rolls extruding plate, between the protuberance 11 that sheet is sandwiched into upside knurling rolls 10 and the protuberance 21 of downside knurling rolls 20, the part of the sheet of the cutting position 5 between protuberance is subject to load, and sheet breaks because of shearing force.
Should illustrate, the Cutting Length of cutting part 4 suitably changes by changing the size of protuberance itself certainly, even if but the size not changing protuberance itself also can adjust Cutting Length.Specifically, by change protuberance each other dislocation distance in the Y direction adjust, as shown in Figure 8, when not making protuberance misplace in the Y direction each other, the length of the cutting position 5 of protuberance 11 side relative with the protuberance 21 of downside knurling rolls 20 of upside knurling rolls 10 reaches the longest, can extend Cutting Length.In addition, as shown in Figure 9, when shortening the length of protuberance side respect to one another when making protuberance 21 misplace in the Y direction, the length of cutting position 5 shortens, and can shorten Cutting Length.
