Problems solved by technology

[0014] However, the technology of Patent Document 2 also has the disadvantage that the semi-finished product is made immediately after the application of the chemical solution, so that the chemical solution diffuses into the paper after the semi-finished product is manufactured, and the paper is easily stretched due to the elongation of the wrinkles. Rolling deviation and shape damage of semi-finished products
[0018] However, in the technique cited in Document 3, since water is applied by spraying before embossing, the embossing process is performed before the continuous paper is sufficiently saturated with the chemical solution or water, so the non-impregnated chemical solution on the surface of the continuous paper It will adhere to the embossing roll and backup roll for embossing, which will become the main cause of line stoppage caused by paper breakage and cleaning, so productivity cannot be improved
[0019] Moreover, an oily chemical solution is known as a chemical solution that reduces paper strength when the chemical solution is applied, and roll toilet paper using the oily chemical solution is also known. However, the surface of the roll toilet paper The improvement of smoothness is sufficient but the moisture retention is not sufficient, and this is due to the use of an oily chemical solution that is difficult to penetrate into the paper layer even in the chemical solution
Furthermore, there are difficulties in terms of the necessary hydrodisintegratability of the toilet paper roll

[0129] "First embodiment: form without embossing"

[0130] [Papermaking process: Primary paper roll manufacturing method and manufacturing equipment]

[0131] The primary paper roll JR (also called jumbo roll) of the present invention can utilize figure 1 The illustrated papermaking apparatus example X1 was manufactured as follows.

[0132] First, from the top box 31, the paper stock prepared by adding an appropriate reagent to the pulp slurry is supplied onto the wire 32w of the wire part 32 to form wet paper W (forming process), and then the wet paper W is transferred to After pressing the felt 33F of the part 33, it is pinched by the pair of dewatering rolls 34 and 35, and dehydration is performed (dehydration process).

[0133] Next, after drying the dehydrated wet paper W by attaching it to the surface of the Yankee dryer 36, it is peeled off with a scraper 37 to become dry base paper S1 (primary continuous paper described later) with wrinkles (drying base paper W). pr...

[0223] "Second embodiment: a form in which a single emboss is applied by a laminator"

[0224] Next, with particular reference to Figure 9 , Figure 10 A second embodiment of the present invention will be described. In addition, the configuration other than the configuration in which so-called single embossing is applied to the stacked continuous paper sheets S2 and S3 in the stacker X2 is the same as the above-mentioned first embodiment, as described above.

[0225] Such as Figure 9 As shown, the laminator X2 of the second embodiment is provided with an embossing unit 60 at the rear stage of the chemical solution applying unit 53, and the embossing applying unit 60 is used to perform lamination after the chemical solution is applied by the chemical solution applying unit 53. The continuous paper S3 was embossed. In addition, the embossing mentioned here refers to the embossing applied to the entire paper surface in order to improve bulkiness, design, and surface propert...

no. 3 approach

[0234] "Third embodiment: A form in which double embossing is applied by a laminator"

[0235] Next, with particular reference to Figure 11 A third embodiment of the present invention will be described. In addition, this mode is the same as the above-mentioned first embodiment, as described in the above description, except for the structure of applying so-called double embossing to the laminated continuous paper in the laminator X2 and the structure related to the structure. In addition, the structure of each embossing unit 60 and embossing, embossing application conditions, etc. are the same as those of the above-mentioned second embodiment, as described above.

[0236] Next, differences between the first embodiment and the second embodiment will be described in detail.

[0237] Figure 11 The laminator X2 of the third embodiment shown is sequentially provided with: a superimposing unit 51 for making the primary continuous sheets S1 and S12 into stacked continuous paper; ...

Abstract

To efficiently produce a toilet roll product treated with a drug solution. A primary jumbo roll manufactured by paper-making equipment is fashioned into a secondary jumbo roll provided with a drug solution using a ply machine. The secondary jumbo roll is used to produce a log using a winder.

Description

technical field [0001] The present invention relates to a rolled toilet paper product obtained by packaging a rolled toilet paper produced by winding a wrinkled toilet paper coated with a chemical solution, and a manufacturing method thereof. Background technique [0002] Toilet paper is usually in the form of a toilet paper roll formed by winding continuous strip-shaped toilet paper around a core called a paper tube, and is supplied as a rolled toilet paper product in a state where a plurality of toilet paper rolls are packaged. sell in the market. [0003] Among the above-mentioned sanitary papers, consumers are concerned about moisture retention (moist feeling), softness (soft feeling), and surface smoothness (smooth feeling) as well as price, and demand high-quality toilet paper in these respects. [0004] Furthermore, for patients with hemorrhoid disease, it is difficult to perform cleaning and wiping such as strong wiping in the cleaning and wiping work after excretio...
