Need to prove, in the manufacturing approach of this paper roll, after utilizing scraper 117 to peel off, also can impose smoothing and handle through calender unit 118.

(thin-paged paper products is with the manufacturing equipment of secondary paper roll)

Shown in figure 11; Thin-paged paper products of the present invention can be laid more than two a paper roll JR who makes through above-mentioned manufacturing approach etc. at least with the manufacturing equipment X3 (range upon range of machine X3) of secondary paper roll; Have lamination unit 51, this lamination unit 51 will carry out lamination along its continuous direction by the one-time continuous paper (being S11, S12 in the illustrated example) that these paper roll JR extracts out and process lamination continuous form S2.

Back segment at lamination unit 51 is provided with the contact embossing unit 54 of the lamination continuous form S2 that is sent by lamination unit 51 being given the contact embossing, is provided with a pair of soup coater unit 53 that carries out the soup coating at its back segment.And; The backend configuration of these soup coater units 53 have by and the rip cutting unit 55 that constitutes of two above cutters establishing; It carries out rip cutting to the lamination continuous form S2 that is transported by soup coater unit 53, is cut into the goods width or the above width of its twice of thin-paged paper products; Back segment in rip cutting unit 55 is provided with winding unit 56, and it carries out coaxial batching to the lamination continuous form S2 that has been carried out rip cutting by rip cutting unit 55, forms the goods width of thin-paged paper products or the plural secondary roll R of the above width of its twice.Here, this winding unit 56 has two reel cylinder 56A that are used for guide to the secondary roll R through each lamination continuous form S2 of rip cutting, and the outer peripheral face of these two reel cylinder 56A and secondary roll R joins, guiding lamination continuous form S2.

(calender unit)

Can be provided with more than one calender unit 52 of lamination continuous form S2 being rolled processing among the manufacturing equipment X3 of thin-paged paper products with the secondary paper roll.

Calendering classification in the calender unit 52 is not special to be limited, but from the reason of the thick adjustment of the raising of surface smoothing property and paper, is preferably soft calendering or colds pressing and prolong (チ Le De カレンダー).The calendering of soft calendering for using the roller be coated with elasticity materials such as urethane rubber to carry out colded pressing and prolonged the calendering for being formed by metallic roll.

The number of calender unit 52 can suit to change.If be provided with a plurality of, even then have the process velocity also abundant advantage of smoothing soon; On the other hand, if one, even then have the advantage that narrow space also can be provided with.

Under the situation that two or more calender unit 52 is set, can and be located at horizontal direction, above-below direction or incline direction, and also can direction combination be set and be configured these.And if be located at horizontal direction, then because to hold around angle (embracing the I angle) little, thereby can to make process velocity be at a high speed; If at above-below direction and establish, then can reduce to be provided with the space.Need to prove, said here hold around the angle mean from the axle center of roller observe paper join between the angle (as follows) of the part of the circular arc in craspedodrome cross section (axle with).

Also can the calendering classification of calendering in the treatment conditions, nip linear pressure, nip number etc. be copied paper as the control essential factor, these control essential factors are that the thick and superficiality of paper suit to change according to the quality of desired tissue paper preferably.

And, calender unit 52 be provided with that the position is not special to be limited, can select the back segment of lamination unit 51 and be the leading portion of contact embossing unit 54, also can select the back segment of soup coater unit 53 and be the leading portion of rip cutting unit 55.

(soup coater unit)

In the manufacturing equipment or manufacturing approach of the thin-paged paper products of this embodiment with the secondary paper roll, carry out on the two sides of lamination continuous form S2 under the situation of coating of soup, the total soup coating weight on two sides is 1.5～5.0g/m ², be preferably 2.0～4.5g/m ², 2.5～4.0g/m more preferably ²If surpass 5.0g/m ²Surpass, break paper or volume takes place when utilizing reel cylinder to batch and squint such as then reduce or elongation owing to paper power, and aspect quality, also the sense of being clamminess may be arranged too.If less than 1.5g/m ², then possibly experience less than the quality discrepancy with uncoated article such as smooth feeling or moist feeling.

Need to prove; Coating weight at two coated faces has under the situation of difference, is being saved in the time (more than 8 hours) till folding processing with lamination body paper (プライ is former anti-) from being coated with the back, and two coated faces join; Thereby the equalization gradually of both amount of liquid medicine, surperficial back side difference diminishes.

Soup only is coated under the situation of single face of lamination continuous form S2, the coated face of soup gets final product for the coating that the inboard face (face of one-time continuous paper S11 side) of secondary roll R that is positioned to lamination continuous form S2 carries out.If so,, be difficult for producing the circumvolution skew although then in goods, have surperficial back side difference.In this case, coating weight is 1.5～5.0g/m ², be preferably 2.0～4.5g/m ², 2.5～4.0g/m more preferably ²

And the crepe ratio at each the one-time continuous paper that constitutes lamination continuous form S2 is provided with under the situation of difference, has also proposed the scheme of the one-time continuous paper side high to crepe ratio (being one-time continuous paper S11 side in the illustrated example) the more soup of coating.For example, in Figure 11 and example shown in Figure 20, among two soup coater units 53, directly the soup coater unit 53B of coating soup is coated with more soup than another soup coater unit 53A on one-time continuous paper S11.In this case, the ratio of the soup coating weight on two sides is 100:0～60:40, is preferably 75:25～60:40.

Figure 20 (A) is the sectional view (sectional view that cuts off abreast with the MD direction) of 2 layers lamination continuous form S2 for the lamination before the soup coating.When lamination was 2 layers the two sided coatings soup of lamination continuous form S2, the amount of liquid medicine on the two sides was provided with difference, and is among the figure, many in the coating of the side soup of one-time continuous paper S11.After the soup coating, before lamination continuous form S2 elongation, utilize contact embossing CE integrated, cut into goods width (Figure 20 (B)) through rip cutting unit 55 to pressing layer to carry out., utilize winding unit 56 pair lamination continuous form S2 batch,, leave standstill for making the soup infiltration thereafter.Mainly in MD direction elongation, one-time continuous paper S11, S12 utilize soup coater unit 53 to be coated with soup for one-time continuous paper S11, S12, and one-time continuous paper S11, S12 constitute lamination continuous form S2.At this moment; The percentage elongation that is coated with the one-time continuous paper S11 of multiple medicines liquid more is greater than other one-time continuous paper S12; But owing to one-time continuous paper S11, S12 interfix through contact embossing CE, thereby produce wrinkle (Figure 20 (C)) on the surface of the more one-time continuous paper S11 of elongation.If the lamination continuous form S2 that carries out lamination then can make the percentage elongation between one-time continuous paper S11 and the one-time continuous paper S12 produce more big-difference also being provided with difference aspect the crepe ratio, in one-time continuous paper S11, using the high body paper of crepe ratio.

After utilizing 115 pairs of body paper of Yang Keshi drying cylinder to carry out drying back, utilizing scraper 117 to be peeled off by Yang Keshi drying cylinder 115, the difference through drying machine speed and coiling speed forms wrinkle.This wrinkle is adjusted shape through on Yang Keshi drying cylinder 115, attaching paster, but because this attaches subsides not equal distribution of fluctuation or fibrous raw material can be arranged slightly, thereby if observe with microscopic field, then the wrinkle three-dimensional shape has fluctuation slightly.Crepe ratio is big more, and then should fluctuate (ばらつ I) is remarkable more.

Accompany with the fluctuation of this wrinkle, the elongation during the coating soup also produces fluctuation, and its form with three-dimensional fine ripple (ripple is beaten Chi) forms.For this ripple, tension force plays a role during owing to the body paper drying, thereby this wrinkle and not obvious; , the processing severing recovers apparition after becoming goods.The coating weight of soup on paper is many more, and then wrinkle is big more, and the ripple of wrinkle shape variation, paper is big; Otherwise the coating weight of soup on paper is few more, and then wrinkle is more little, and the ripple of wrinkle shape variation, paper is more little.Therefore, not only, also, can make and improve fluffy (high height) effect simultaneously through changing crepe ratio through changing coating weight.

And, about quality, form at the one-time continuous paper S11 different, S12 lamination under the situation of goods, if do not carry out the soup coating, then as the volume sense (sense of バ Le Network) different (Figure 21 (A)) on the tissue paper two sides of goods to crepe ratio.But; Although concavo-convex bigger (crepe ratio is high) one-time continuous paper S11 through to the surface is coated with more multiple medicines liquid; One-time continuous paper S11 is extended with high elongation rate more than one-time continuous paper S12; But owing to fix (not shown) abreast through contact embossing and MD direction, thereby volume (high) increase of ripple, lamination paper takes place in one-time continuous paper S11.(Figure 21 (B)).

When the soup coating weight there are differences; Although worry the goods two sides touch the skin sense, usability can be different; But through make the secondary roll R the operation (folding processing etc.) that is supplied to the back before the state with paper roll leave standstill; One-time continuous paper S11 that can the soup coating weight is different, the surface of S12 keep (soup infiltration operation, Figure 22) with state respect to one another; Thereby the medicine liquid ingredient between continuous form little by little shifts (grey arrow among the figure), and its difference is being dried! シーズニ Application グ) in reduce gradually.Need to prove that the hollow arrow among Figure 22 is represented the infiltration direction of medicine liquid ingredient.

In addition, the kind of soup coater unit 53 is not special to be limited, and can use mode of printings such as intaglio printing mode or flexographic printing mode.
