DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a moisturizing property of a toilet paper which has a large hole having the same size as the outer diameter of a winding shaft at the center and has a moisturizing property. The present invention relates to a method for producing a roll-shaped toilet paper roll in which toilet paper is wound around the outer circumference of a temporary fitting core.

[0002]

2. Description of the Related Art As a conventional method for producing a very ordinary toilet paper roll, it is loosely wound around a paper tube core (paper tube) which is a core having a diameter of about 3.8 cm and has an outer diameter of 65 m. Is making a cored toilet paper roll of about 11.5 cm. Further, as a conventional method of producing a coreless toilet paper roll, when wound around a winding shaft, an adhesive liquid such as water or glue is sprayed onto the toilet paper at a predetermined amount per unit area of the toilet paper, for example, 0.003 cc / cm ^2. A coreless toilet paper roll is manufactured by pulling out a winding shaft (see Japanese Patent Publication No. 63-34666).

[0003]

In the former conventional method for manufacturing a very ordinary cored toilet paper roll, the paper core is required, and therefore the cost is high because the paper core is required at the time of production. In addition to the above problem, there is a problem that the paper tube core (paper tube) must be discarded because the paper tube core, which is the core, remains after using all the toilet paper in a general household, office, company, or the like. Further, in the latter non-core toilet paper roll manufactured by the latter conventional coreless toilet paper roll, when the amount of water to be sprayed is increased, the temporary-fitting cylinder core is preferable because the temporary fitting becomes strong, but the temporary-fitting cylinder core is used as the toilet. There is a problem that the toilet paper is difficult to peel off or does not peel off when it is used as paper because it is strong (bonded state), and if the amount of water sprayed is too small, the temporary attachment strength of the temporary attachment cylinder core will increase. There is a problem in that it is too small to make a temporarily attached tubular core that is temporarily attached.

The present invention solves the above problems of the conventional methods of manufacturing cored or uncore toilet paper rolls, strengthens the temporary attachment of the temporary attachment tubular core, and To improve shape retention, to prevent the innermost toilet paper of the temporary fitting core from getting entangled with the core rod of the holder or the nail of the one-touch holder, to make the toilet paper roll easily, and to reduce the cost That is, the inside of the toilet paper roll does not always lose its shape, and a toilet paper roll that has a large hole of a predetermined size in the center and is well-shaped like a roll is formed. Of the toilet paper roll so that it does not deform during normal distribution or household handling. The paper tube core does not remain after use with the use of all the temporarily sticking cylinder core toilet paper are temporarily attached during unwinding as toilet paper as toilet paper is intended and the like.

[0005]

According to the method of manufacturing a toilet paper roll of the present invention, a retractable winding shaft having an outer diameter which is the same as that of a paper tube core is attached to a winding start end of the toilet paper or 30 cm from this end. from the point of 70cm of polyvalent alcohol in toilet paper aqueous solution or multivalent Al
While spraying the call emulsion, wrap the toilet paper tightly to form a temporary sticking core of the toilet paper on which the toilet papers are temporarily attached, and to the outside of the temporary sticking core of the toilet paper that has moisture retention. After loosely or tightly winding the toilet paper in a roll shape and after a lapse of a predetermined time until the temporary attachment cylinder core does not lose its shape, the outer diameter of the retractable hard winding shaft is reduced to reduce the shrinkage. The toilet paper roll is manufactured by pulling out the rolled toilet paper from the hard winding shaft.

[0006]

[Effect] In this toilet paper manufacturing process of the roll of the invention the outer diameter of hard contraction freely expanded the same as the paper tube core winding axis, from the beginning of the end or the end winding of toilet paper 30
cm to 70 cm, the toilet paper is tightly wrapped around the toilet paper while spraying the polyhydric alcohol solution, and the toilet paper is temporarily attached to the toilet paper and the temporary attachment of the toilet paper having a moisturizing property for the polyhydric alcohol. After forming the tube core and winding the toilet paper in a roll shape on the outside of the temporary attachment tube core of the toilet paper, the temporary attachment tube core does not lose its shape. After 7 minutes or more, this shrinkable hard winding shaft The outer diameter of the roll is reduced, and the roll-shaped toilet paper rolled from this retractable hard winding shaft is pulled out to separate the two, producing a toilet paper roll. Since this part has a temporary-fitting core that is well-temporarily attached to the end of the roll of toilet paper, this temporary-fitting core has good shape retention. Since with the toilet paper roll having substantially the same relatively large hole and the outer diameter of the winding shaft in the center with better shape retention into a roll can build. In addition, the cost can be reduced because the paper tube core is not used during production and it is attached to the normal holder during use. When using it, the innermost toilet paper roll of the toilet paper roll is also well temporarily attached as a temporary fitting core, so the beginning end of the toilet paper roll may become entangled with the holder core rod or the one-touch holder claw. Since the sprayed polyhydric alcohol has a moisturizing property, the temporarily attached toilet paper peels off well at the time of use, and the entire toilet paper up to the temporary attachment of the toilet paper roll can be used. At the same time, no conventional paper tube core (paper tube) remains.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method for manufacturing a toilet paper roll according to the present invention will now be described with reference to the drawings. (Embodiment 1) The outer diameter which is almost the same as that of the conventional paper tube core, for example, the diameter is about 3.8c.
A retractable hard metal winding shaft 1 expanded to an outer diameter of m is placed on two parallel drums 2.2, and a riding roll 3 serving as a pressure roll is provided on the winding shaft 1. .
The toilet paper 4 is supplied to the winding shaft 1, and 100% ethylene glycol liquid and water are mixed in the toilet paper 4 from the winding end 4'of the toilet paper 4 at a mixing ratio (volume ratio) of 0, 5: 1 ethylene. An aqueous solution of glycol is sprayed from the spray nozzle 5 at a conventional spray amount (0.00
3 cc / cm ² ) is sprayed over a length L of about 50 cm. Sprayed ethylene glycol
The toilet paper 4 is temporarily adhered to the inside of the toilet paper 4 with a large amount of ethylene glycol liquid, which is about 1, 5 times as much as usual, and water by the aqueous solution to form the temporarily attached cylinder core 6 of the toilet paper. Subsequently to the outer circumference of the winding shaft 1 and the temporary attachment cylinder core 6 of the toilet paper 4, the toilet paper 4 is tightly wound while being pressed by the riding roll 3. As with a normal toilet paper roll, the outer diameter is tightly wound to about 11.5 cm, and then the winding is stopped. Leave the same for about 10 minutes for a predetermined time (that is, a predetermined time until the water is substantially dried and evaporated) until the temporary attachment cylinder core 6 is substantially completed with the aqueous solution of ethylene glycol. After being placed, the outer diameter of the stretchable rigid winding shaft 1 is shown in FIG. 4 so that the toilet paper roll 7 having the temporarily attached core 6 wound tightly cannot be removed from the shrinkable rigid winding shaft 1 as it is.
Toilet paper roll 7 that is wound tightly after being reduced like a virtual line is made up of only toilet paper roll 7 that is pulled out from reel 1 and removed and then tightly wound, and has a large hole 8 of about 3.8 cm in the center and the toilet A toilet paper roll 7 having a temporarily-fixed paper core 6 and having a shape of a roll is formed.

The toilet paper roll 7 produced by the manufacturing method of this embodiment 1 is temporarily attached with a stronger temporary attachment force than that of the toilet paper roll 7 wound from the beginning 4'of the toilet paper only with water. Since it has the cylindrical core 6, the shape of the peripheral portion of the large hole 8 of the toilet paper roll 7 is very good, and the outer diameter of the toilet paper roll 7 is about 11.5 cm, which is almost the same as the conventional one. Since the length of the toilet paper is about 130 m, the toilet paper having the same outer diameter and the length of about 65 m is about twice as long as the toilet paper can be made to have substantially the same volume. And, it can be used for a long time, and it takes about half the time to change the toilet paper roll to the holder. When the toilet paper temporary attachment tube core 6 of the toilet paper roll 7 is attached to the holder and used, it is sufficiently temporarily attached from the end 4 ′ at the beginning of winding with a strong temporary attachment force. The end of the paper at the beginning of winding does not become entangled, and the temporary attachment tube core 6 of the toilet paper that is temporarily attached is in a state where it is temporarily attached with water and ethylene glycol liquid and is always moisturized with ethylene glycol having a moisturizing property. Since the difficulty of peeling the temporarily attached toilet paper is alleviated by ethylene glycol, the toilet paper that is strongly temporarily attached is in a state that it is easy to remove. Pull out and use the entire toilet paper as toilet paper. Example 1 100% ethylene glycol solution to water compounding ratio as <br/> aqueous solution of ethylene glycol spraying has been described (by volume) 0,5 versus 1,0 for mixing ratio is 0,5 to About 1, 5 to 1.0 is preferable, and as the polyhydric alcohol, in addition to the ethylene glycol of Example 1, an aqueous solution of a substituted ethylene glycol is used.
And propylene glycol (divalent), glycerin (3
Valence), Erythritol (4 valences), Pentit (5 valences), Hexit (6 valences) and the like, and their substitution products, for example, stearic acid monoglyceride and the like,
And the water-insoluble polyhydric alcohol is preferably an emulsion with water or the like.

(Second Embodiment) As in the first embodiment, the toilet paper is supplied to the winding shaft having an increased outer diameter, and as shown in FIG.
The amount of glycerin solution prepared by mixing 100% glycerin solution and water in a ratio of 1: 1 to the toilet paper from the position 14 'of m is about 50 times as long as about 50 times the conventional spray amount (0.003 cc / cm ² ). Spray over. The sprayed aqueous glycerin solution permeates the inside and outside of the toilet paper wound around the winding shaft and is diffused, so that the toilet paper at the inner end of the toilet paper is about twice as large as the usual amount of glycerin liquid and water. Form the temporary attachment core of the toilet paper that is well attached. A predetermined amount of the toilet paper is continuously wound around the outer circumference of the reel and the temporary attachment core of the toilet paper, and the toilet paper is left for about 10 minutes as in Example 1, and then the outer diameter of the reel is reduced to make the toilet paper. The roll is removed from the winding shaft to make a roll-shaped toilet paper roll having a temporary core of toilet paper.

Since the toilet paper roll manufactured by the manufacturing method of the second embodiment has the temporary attachment cylinder core of the toilet paper temporarily attached to the end of the roll of the toilet paper with a strong temporary attachment force, it has a large hole. The shape of the whole area such as the peripheral part is very good.

In the manufacturing method of this Example 2, the glycerin aqueous solution was sprayed onto the toilet paper from a position about 50 cm from the winding start end of the toilet paper. Excessive glycerin solution may stick the paper to the reel, and the glycerin solution may be soaked in a large amount to cause unnatural and ugly `` wrinkles '' on the toilet paper. since the end of the first winding of toilet paper it is not sufficiently temporarily attached good from the point of the test result as a toilet from about 30cm to about 70cm from the beginning of the end turns of the paper. In addition, the time required for the temporary attachment core to be almost completed is about 7 minutes or more when tested, and the longer the better, the better, but from the viewpoint of productivity, about 7 minutes to about 15 minutes is preferable.

[0012]

According to the method of manufacturing a toilet paper roll of the present invention, a retractable hard winding shaft whose outer diameter is enlarged to the same as that of the paper tube core is provided with the end of the winding start of the toilet paper or from 30 cm to about 70 cm from this end. Water or polyhydric alcohol from a location to toilet paper
While spraying the emulsion of , toilet paper,
After wrapping, the toilet paper members are temporarily attached to each other to form a temporary attachment tube core for the toilet paper, and the toilet paper roll is wound around the outside of the temporary attachment paper core to cause the temporary attachment cylinder core to lose its shape. After a lapse of time, the outer diameter of the retractable hard winding shaft is reduced, and the retractable hard winding shaft and the rolled toilet paper roll are separated to produce a toilet paper roll having a temporary core. Since it is a method, a temporary tube core should be
Moisture-retaining temporary toilet paper

Since the shape-retaining property is improved as described above, there is an effect that the toilet paper roll is not deformed during normal handling at the time of distribution or at home. And when the toilet paper roll is used, the toilet paper roll at the beginning of the roll, which is the end of the toilet paper, forms the innermost part of the temporarily attached tube core that is firmly attached, so that it can be attached to the core rod of the holder or the nail of the one-touch holder. There is an effect that the end of the toilet paper does not get entangled and an effect that the toilet paper roll can always be easily attached to the holder which has been used more normally than ever before. In addition, you can easily make a toilet paper roll that has a temporary attachment core with a large hole in the center, and because it does not use a paper core (paper tube) during production and it can be attached to a normal holder as it is. The cost can be reduced because the specially shaped core rod is not used. In the toilet paper roll manufactured by the manufacturing method according to claim 2 , the toilet paper is wound around the reel.
