Extension, so, compared with the top of convex portion, fibre density is big.
Therefore, in the case where having carried out air attraction from the second surface side of the figuration piece, the small convex portion of fibre density
Top, the circulation of air is more, and in the case where skin conditioner is sprayed, skin conditioner is easily as air stream is attached to convex portion
Top and its near.Conversely, for the bottom of the fibre density recess bigger than the top of convex portion, from the second surface side of figuration piece
In the case of carrying out air attraction, compared with the top of convex portion, the circulation of air is few, even if skin conditioner is sprayed, there is also
The tendency that the skin conditioner can not move too much in the bottom of recess.Patent document 1 utilizes this principle so that skin conditioner is only attached
The top to convex portion.
But in the case of the technology of the patent document 1, although having the top that skin conditioner is readily adhered to convex portion really
The tendency in portion, still, because figuration piece is the piece of adhesive-bonded fabric etc., substantially thin slice in itself, so, pass through the bottom of recess
Air flowing it is quite a few.
Therefore, a part for the skin conditioner of spraying, moved sometimes by the air-flow of air to the bottom of recess, moreover, shield
A part for skin agent is not influenceed by the circulation of the air by convex portion, and is dropped on figuration piece, so, in fact, skin care
Agent is also applied to the bottom of recess.

In the case of, in heating process, in the feelings that the temperature (temperature of the outer peripheral face of heating roller) with 60~70 DEG C or so is preheated
Under condition, it can be heated using 90~100 DEG C or so of temperature (temperature of the outer peripheral face of the first figuration roller 25).
And then in the figuration piece formation process, make the transporting velocity of the serialgram 2 of the upstream of a pair of figuration rollers 25,26
The peripheral speed of than a pair of figuration rollers 25,26 is fast.So as to, can be with when using a pair of figuration rollers 25,26 by 2 figuration of serialgram
Suppress deformation of the serialgram 2 on conveying direction MD.In addition, the transporting velocity of serialgram is according to the convex portion of the figuration piece of figuration
Highly, the depth of recess, the raw material etc. of serialgram determine.
After the figuration piece formation process terminates, implement the pull-out process.
The pull-out process, by making the peripheral speed of than a pair of figuration rollers of peripheral speed 25,26 of the first conveying roller 7 fast,
Figuration piece 5 is pulled out between a pair of figuration rollers 25,26 using the first conveying roller 7.At this moment, due to the circumference of the first conveying roller 7
The peripheral speed of a pair of figuration rollers of speed ratio 25,26 is fast, so, towards conveying direction MD tension force effect in a pair of figuration rollers
25th, on the figuration piece 5 passed through between 26.
The peripheral speed of first conveying roller 7 of present embodiment is such speed：The speed causes in a pair of taxes
The figuration piece 5 passed through between shape roller 25,26 makes figuration piece 5 extend in the conveying direction towards conveying direction MD working tensions,
So that its width becomes the width than serialgram 2 and then the original width than figuration piece 5 (does not make tension force to conveying direction
Width in the state of MD effects) it is small.
In addition, in the pull-out process, why make the peripheral speed of the first conveying roller 7 than size enlargement apparatus b a pair of taxes
The peripheral speed of shape roller 25,26 is fast, and figuration piece 5 is pulled out between a pair of figuration rollers 25,26, is in order to which one side is properly maintained
Convex portion 11 and recess 12, the shape of recess 13, while figuration piece 5 is taken out between figuration roller 25,26.In addition, as below
It is in painting process, easily only be coated with skin conditioner 17 in convex portion 11 as will describing.
After the pull-out process, implement refrigerating work procedure, in the refrigerating work procedure, will be assigned by the pull-out process from a pair
The figuration piece 5 pulled out between shape roller 25,26 cools down.
The refrigerating work procedure is will to be remained in because of the heating in the preheating procedure and figuration piece formation process to serialgram 2
The process that heat in figuration piece 5 removes.In addition, the cooling in the refrigerating work procedure to figuration piece 5, as long as can will be described
The heat that serialgram 2 heats is removed in preheating procedure and figuration piece formation process, so as to, as long as the temperature by figuration piece
Be reduced to normal temperature (in this case, for set manufacture device 1 place temperature) can.
So, due to by implementing refrigerating work procedure before painting process, being applied in painting process on figuration piece 5
Skin conditioner be not readily susceptible to heat influence, so, can suppress by figuration piece 5 heat and make skin conditioner 17 change of properties,
Or bottom 12a movement of the skin conditioner 17 from convex portion 11 to recess 12 is caused from the reduction of the viscosity of skin conditioner 17.
In the present embodiment, for from the figuration piece 5 pulled out between a pair of figuration rollers 25,26, by until being used as
Conveying in a period of untill skin conditioner 17 is applied on the convex portion 11 of figuration piece 5 in the painting process of subsequent handling, reduce
The temperature of figuration piece 5.In addition, in the refrigerating work procedure, tempering air can also be made to be contacted with figuration piece 5, forced
The cooling of property.
After the refrigerating work procedure terminates, implement the painting process.
In the painting process, figuration piece 5 is set to be extended on conveying direction MD, so that its width becomes wider than serialgram 2
Spend small.Also, while keep making the state that figuration piece 5 extends on conveying direction MD, while from the lateral convex portions 11 of the first face 5a
It is coated with skin conditioner 17.
Here, why figuration piece is extended with so that the width of the figuration piece becomes than in a pair of taxes in the conveying direction
Width between shape roller by the serialgram in the state of before is small, is to easily and stably only be coated with skin care to convex portion
Agent.
In the case where being coated with skin conditioner to the convex portion of figuration piece, for example, being used for absorbability with piece in absorbent commodity
When in article, in order to prevent from hindering absorption of the discharged liquid of the user of absorbent commodity to absorber, not to as closest
The bottom coating skin conditioner of the recess of the figuration piece at the position of absorber is very important.
As the measure that skin conditioner is only coated with to the convex portion of figuration piece, it may be considered that by stably keeping figuration piece
The shape of convex portion so that the difference in height of the top of convex portion and the bottom of recess is fairly obvious, is easily coated with skin conditioner to convex portion.
Particularly, in the case where carrying out the coating of skin conditioner using the apparatus for coating of contact, it is necessary to relative to direct with convex portion
For the pushing of the coated member of contact, the deformation (particularly, the damage of convex portion) of convex portion does not occur as much as possible.
In addition, as other measures that skin conditioner is only coated with to the convex portion of figuration piece, it may be considered that reduce adjacent convex
The distance between portion, reduce the bottom of recess of figuration piece to the scope of exposing in the first face of figuration piece, suppress skin conditioner attachment
To the chance of the bottom of recess.
Therefore, in the present invention, figuration piece is made to extend in the conveying direction so that its width becomes the width than serialgram
It is small, suppress the deformation of convex portion, in addition, reducing the distance between adjacent convex portion.
It is described in detail below for this point, figuration piece is extended in the conveying direction so that its width becomes
In the case of smaller than the width of serialgram, two sides on the width positioned at figuration piece (extend in the conveying direction
Both sides) lateral region, along with the elongation to conveying direction, figuration piece width retraction (phenomenon that width diminishes).At this moment, such as
Shown in Fig. 5 (a), (b), by the width retraction, produced in the region at the width CD of figuration piece 5 both ends to width
The power F of CD interior side direction1, interior side direction of the lateral region 50,50 into the width CD of figuration piece 5.So as to due to hair
The convex portion 11 of lateral region 50,50 is given birth to close to the phenomenon of adjacent convex portion 11, so, the distance between adjacent convex portion 11 is i.e. recessed
The width (spacing of convex portion) in portion 12 diminishes.
In addition, in the case of shown in Fig. 5 (b), lateral region 50 turn into from the width CD of figuration piece 5 ora terminalis with
1/4 degree of the width of figuration piece enters the region of the part of the width CD of figuration piece 5 interior side direction.In in addition,
Region 51 is entreated to turn into the width portion of 1/2 degree of the width of figuration piece 5 as the region clipped by these lateral regions 50,50
The region divided.
In addition, figuration piece is set to extend in the conveying direction so that its width becomes the situation smaller than the width of serialgram
Under, as shown in Fig. 5 (a), in the middle section 51 clipped by lateral region 50,50, produce the width retraction along with figuration piece 5
And the power F of caused interior side direction from the width CD to figuration piece 51Reaction force, that is, produce the width to figuration piece 5
The power F of direction CD lateral direction2。
At this moment, as shown in Fig. 5 (b), because middle section 51 is by the lateral direction drawing of from the width CD to figuration piece 5
Stretch, so, the distance between adjacent convex portion 11 and convex portion 11 will not produce big variation, conversely, convex portion 11 or formation are convex
The fiber in portion 11 turns into tense situation, the dimensionally stable of convex portion 11.So as in middle section 51, can stably keep figuration
The shape of the convex portion 11 of piece 5.Particularly, the coating structure in the apparatus for coating 9 of contact as in this embodiment
In the case that part 41 contacts with convex portion 11, due to suppressing what convex portion 11 deformed by the pushing of coated member 41 as much as possible
On the basis of, also suppress coated member 41 and contacted with the bottom 12a of recess 12, so skin conditioner 17 only can be coated with to convex portion 11.
In the present invention, using by making figuration piece extend in the conveying direction so that its width becomes wider than serialgram
Spend it is small and caused, in the middle section of figuration piece and the above-mentioned phenomenon of lateral region, can be easily and stably by skin care
Agent is coated on convex portion.
Here, in the present embodiment, the peripheral speed for making the second conveying roller 8 is the peripheral speed with the first conveying roller 7
Same speed, figuration piece 5 is existed from the speed pulled out between a pair of figuration rollers 25,26, i.e. figuration piece 5 with the first conveying roller 7
A pair of figuration rollers 25,26 are identical with the transporting velocity between the first conveying roller 7.So as to which figuration piece 5 is by the first conveying roller 7 from one
To being pulled straight out between figuration roller 25,26, still, because the peripheral speed of the second conveying roller 8 is the circumference with the first conveying roller 7
Speed same speed, therefore, it is continuously kept caused by the first conveying roller 7 to conveying direction MD tension force, as a result, second
Conveying roller 8 also carries out figuration piece 5 from the pull-out between a pair of figuration rollers 25,26 indirectly.
So as to which, the second conveying roller 8 is between the conveying roller 7 of the second conveying roller 8 and first, figuration piece 5 can be acted on to
Conveying direction MD tension force, the tension force and is applied between the first conveying roller 7 and a pair of figuration rollers 25,26 on figuration piece 5
The tension force towards conveying direction MD size it is roughly the same.Therefore, figuration piece 5 the second conveying roller 8 and the first conveying roller 7 it
Between between the first conveying roller 7 and a pair of figuration rollers 25,26 the identical degree of figuration piece 5 extend.
As a result, figuration piece 5 between the second conveying roller 8 and the first conveying roller 7 on conveying direction MD by also stretching
Long, its width becomes smaller than the width of serialgram 2.Also, due to the lateral region 50 in figuration piece 5, adjacent convex portion 11 it
Between distance diminish, in middle section 51, can stably keep the shape of the convex portion 11 of figuration piece 5, therefore, become prone to only
Skin conditioner 17 is coated with to convex portion 11.
In addition, as described above, the first conveying roller 7 between first conveying roller 7 and a pair of figuration rollers 25,26, makes figuration
Piece 5 is extended on conveying direction MD so that its width becomes smaller than the width of serialgram 2.Therefore, in the first conveying roller 7 and a pair
In stage between figuration roller 25,26, have occurred and that such phenomenon：Between the lateral region of figuration piece 5, adjacent convex portion 11
Distance diminish, in middle section, stably keep the shape of convex portion 11.
It is thus possible to further stably show such phenomenon：Implementing the first conveying roller 7 and second of painting process
Between conveying roller 8, in the lateral region 50 of figuration piece 5, the distance between adjacent convex portion 11 diminishes, in middle section
51, stably keep the shape of convex portion 11.
The peripheral speed of first conveying roller and the second conveying roller, as long as in the scope that absorbent commodity is not destroyed with piece
Peripheral speed than a pair of figuration rollers is big, it is preferable that the peripheral speed of these first conveying rollers and the second conveying roller is than one
It is big to the peripheral speed of figuration roller by 1~15%.
When being no more than the 1% of the peripheral speed of a pair of figuration rollers in the peripheral speed of conveying roller, figuration piece is to conveying direction
Elongation deficiency, there is a possibility that the width of the figuration piece does not become smaller than the width of serialgram.Accordingly, there exist
The distance between the lateral region of figuration piece, adjacent convex portion 11 does not diminish, unstable in middle section, the shape of convex portion 11
Possibility.Conversely, when conveying roller peripheral speed more than the peripheral speed of a pair of figuration rollers 15% when, for figuration piece to
The overtension of conveying direction, according to circumstances, it there is a possibility that figuration piece destroys.
And then after figuration piece 5 is extended on conveying direction MD, by make the coated member 41 of apparatus for coating 9 with

Sequence, for example, the top sheet as absorbent commodity uses.
As described above, according to the manufacture method and manufacture device of the absorbent commodity piece of present embodiment, in coating work
In sequence, while make figuration piece 5 extend in the conveying direction so that its width becomes smaller than the width of serialgram 2, while from first
The convex portion 11 of the lateral figuration pieces 5 of face 5a is coated with skin conditioner 17.
At this moment, because the lateral region 50 in figuration piece 5, the width of recess 12 diminish, between adjacent convex portion 11 away from
From shortening, so, skin conditioner 17 is easily applied to the top of convex portion 11, on the other hand, because the bottom 12a of recess 12 is to the
Simultaneously exposing for 5a sides diminishes, so, skin conditioner 17 is not easy to be applied to the bottom 12a of recess 12.In addition, in figuration piece 5
Middle section 51, because the effect of the power of the lateral direction by the width CD to figuration piece 5, the shape of convex portion 11 are steady
It is fixed, so, it can stablize and easily carry out coating of the skin conditioner 17 to convex portion 11.
As a result, it can be coated with while suppressing skin conditioner 17 to the bottom 12a of recess 12, on one side stably by skin care
Agent 17 is coated on convex portion 11.
In said embodiment, the conveying roller as the downstream for being arranged on a pair of figuration rollers 25,26, it is defeated to be configured with first
Send conveying roller 8 the two conveying rollers of roller 7 and second.But as long as conveying roller can make the tax after figuration piece formation process
Shape piece extends in the conveying direction so that its width becomes smaller than the width of serialgram, then can also be one, or can also
It is more than three.In addition, in the case where conveying roller is one, by a conveying roller carry out figuration piece from a pair of figuration rollers it
Between the operation of elongation this two to conveying direction of pull-out and figuration piece.
In said embodiment, after preheating procedure has been carried out, in figuration piece formation process, enter by figuration roller
Heating of the row to serialgram 2, the heating to serialgram, can also be heating in preheating procedure and in figuration piece still
A side in heating in formation process.Or it can also might not carry out heating to serialgram.In addition, without
To in the case of the heating of the active of serialgram, it is convenient to omit refrigerating work procedure.
