Wiper blade (outer lamellar body S2 or interior lamellar body S1) by drying drum 16 dryings is wound onto on the winding drum 18,19 (winder drum), scraping blade 17 (doctor blade) in crimping on the surface of drying drum 16, at this moment the rotary speed of winding drum 18,19 is lower than the rotary speed of drying drum 16, because the rotary speed of this drying drum 16 and this winding drum 18,19 is poor, outside lamellar body S2 and (or) interior lamellar body S1 goes up the tiny wrinkle of formation.Outer like this lamellar body S2 and (or) interior lamellar body S1 processed on wrinkle, when giving wiper blade S1 and S2 processing wrinkle, the rotary speed of drying drum 16 and winding drum 18,19 poor, according to different wiper blade and difference, rotary speed extent according to this drying drum 16 and winding drum 18,19, the situation of the wrinkle of interior lamellar body S1 and outer lamellar body S2 processing is different, the percentage of elongation (expansion ratio) of the wrinkle in the time of can regulating wrinkle and stretched (spread).The percentage of elongation of interior lamellar body S1 is little, or is not formed with wrinkle fully.Outer lamellar body S2 is than interior lamellar body S1 percentage of elongation height.
Under the situation of using water miscible adhesives such as carboxymethyl cellulose, to the wiper blade coating aforementioned adhesion agent after implementing the preceding wiper blade of wrinkle processing or implementing wrinkle processing.
Lamellar body S1 and outer lamellar body S2 are superimposed shown in Fig. 2 (A) in aforementioned, and in figure (2) A, behind two sided coatings cement 2 in the table of interior lamellar body S1, outer lamellar body S2, S2 are overlapped in two sides in the table of interior lamellar body S1.For the state that junction surface a is formed as shown in Figure 3 is coated with cement 2.This cement 2 is for example water miscible carboxymethyl cellulose etc.
And, on interior lamellar body S1 overlapping have outside under the state of lamellar body S2, S2, lamellar body is whole on one side by humidification, the part of it is applied cement 2 by heating plate 4 and 5 or warm-up mill clip, and pressurized.The 5a of the portion that vacates that aims at the pattern (pattern) of junction surface a is set on heating plate 5 or the warm-up mill, wiper blade is by this protuberance 5a pressurization, heating, interior lamellar body S1 and outer lamellar body S2 are engaged at junction surface a place, and interior lamellar body S1 and the engaged state of outer lamellar body S2 are shown in Fig. 2 (B).
In engaged like this lamellar body S1 and outside on the lamellar body S2, contain the cleaning soup that is immersed in the metal ion that contains surfactant, anticorrisive agent, deodorant, aromatic in water and the wine material and prevent the wiper blade hydrolysis etc.Behind the impregnation cleaning soup, the wrinkle that is formed on the wiper blade trails, wiper blade is whole to be stretched, but outer lamellar body S2 is than interior lamellar body S1 percentage of elongation height, outer lamellar body S2 when wrinkle stretches integrally stretches bigger than the stretching, extension of interior lamellar body S1, therefore as Fig. 2 (C) shown in, in the row A at junction surface and the zone between row A, formation bulge B on the lamellar body S2 outside.Wiper blade 1 becomes abundant like this.
The cleaning soup of impregnation in the wiper blade 1 as previously mentioned, contains the metal ion of calcium and strontium etc.Interior lamellar body S1 and outside forming the bridge formation complex on the lamellar body S2.Wherein become bridge formation as the carboxymethyl in the water-soluble carboxymethyl cellulose of the water-swellable carboxy methylation paper pulp of adhesive and bonding wiper blade, the metal ion in the aforementioned cleaning soup.And, throw away in the flushing toiler after the use after, the cleaning soup is by a large amount of water dilutions, the adhesive of wiper blade and junction surface can be by water decompositions.
Fig. 3 is representing an example of the joint pattern of junction surface a.
In Fig. 3, interior lamellar body S1 and outer lamellar body S2 are partly being engaged by the junction surface a with the linearity of the weak point shown in (1), and this junction surface a leaves certain interval and forms a line along the Y direction.As shown in Figure 1, along the row of the junction surface a of this Y direction as A, the formed direction of wrinkle b (directions X) of aforementioned junction surface a and outer lamellar body 2 and the orientation (Y direction) of junction surface a have angle and are being formed sideling.So wrinkle b is being interdicted by junction surface a.And the row A of the arrangement of junction surface a is forming with the interval of regulation on directions X.
Behind impregnation algae liquid on each wiper blade S1, S2, the S2, the fine wrinkle b that is processed to form by wrinkle expands towards the Y direction.At this moment, because of interior lamellar body S1 and outer lamellar body S2 are being engaged by the part (1) of junction surface a, in this part (1), outer lamellar body S2 does not stretch to the Y direction.In contrast, in the part (2) that clips by junction surface a and junction surface a, outer lamellar body S2 stretches to the Y direction easily, by this stretching, extension (a) to the Y direction, the part of outer lamellar body S2 (2) is lax easily, and its result is in the zone that is clipped by row A that is arranged on the junction surface a on the Y direction and row A, formed the paddy portion (3) that connects the junction surface a of both sides, and formed mountain portion (4) (expansion B) by the expansion of the part (2) that links both sides.Therefore, in the zone that row A and the row A of junction surface a clip, expansion B forms wavy with roughly the same spacing repeatedly in the arrangement pitches of junction surface a.By forming this expansion B, can improve the effect of wiping of wiper blade 1.
As mentioned above, for the space C that makes this expansion B have appropriateness forms as shown in Figure 1 expansion B, the stretching, extension rate variance of the wiper blade that is caused by the stretching, extension of the wrinkle of lamellar body S1 in aforementioned and outer lamellar body S2 is preferably in 20%～80% the scope.
The wiper blade 1 of Xing Chenging like this as shown in the sectional drawing of Fig. 2 (C), in the row A and the zone between row A of junction surface a, is forming aforementioned expansion B, is forming space C between lamellar body S2 and the interior lamellar body S1 outside by this expansion B.So, the integral body of wiper blade 1 becomes abundant.When this wiper blade 1 poured in the toilet etc. after use, the air among the C of space is discharge the aperture 3 on lamellar body S1 and the outer lamellar body S2 in being formed at.Therefore, the buoyancy of wiper blade is low, in water enters into from this aperture 3 lamellar body S1 and outside between the lamellar body S2, in flushing toiler and purification tank, wiper blade 1 sinks easily.
In wiper blade shown in Figure 2, on the both sides of interior lamellar body S1 and outer lamellar body S2, be formed with aperture 3, even but only outside lamellar body S2 go up formation aperture 3, also can reduce the buoyancy of wiper blade, pour in the toilet easily.

Operation as form aperture on wiper blade forms fibre plate on the ribbon of porous matter, brush air on this fibre plate, also can form the many apertures corresponding to the hole on the aforementioned ribbon.And perforate on whole of wiper blade such as available pin.
Fig. 6 represents is the oblique view that above-mentioned wiper blade 1 is folded 3 state.Fig. 7 is the partial enlarged drawing of Fig. 6.
As shown in Figure 6, wiper blade 1 by folding part (folding part) L1 by 2 doublings, again by folding with folding part (folding part) L2 of aforementioned folding part L1 quadrature, folding is four doublings, be 8 doublings by folding part L3 folding more then, when wiper blade is incorporated in the container, even the size of hand, the size of wiping thing and shape difference, but normally under the state of the state of 4 doublings shown in Figure 6 or 8 doublings, use.Size when launching wiping 1 is an operable big or small degree under the state of 4 doublings or 8 doublings.
On the L2 of folding part, forming wire eyelet (per foration) P1, and wiper blade 1 becomes the state of 2 doublings by aforementioned folding part L1, cuts off out by aforementioned wire eyelet, can be separated into 2.This wire eyelet P1 is forming with a determining deviation for short otch.And shown in Fig. 6 and Fig. 7 (partial enlarged drawing of Fig. 6), on the L1 of folding part, preferably partly be formed with long otch P2 and P3.This otch P2 and P3 are than long many of each otch of aforementioned wire eyelet P1.Aforementioned otch P2 be formed at folding part L1 1 on, otch P3 is formed on the part that folding part L1 and folding part L2 intersect.
Therefore, after cleaning, wiper blade 1 is with the state that is folded into 2 doublings by folding part L1 or when throwing away in the flushing toiler with the state of 4 doublings shown in Figure 6,8 doublings, and the air in the paddy part of the wiper blade of the state of folding part L1 doubling is easily run away to the outside of wiper blade from otch P2, P3.Therefore, can not make the buoyancy of wiper blade 1 become big, be sunken at an easy rate in the water of flushing toiler or clean water tank owing to the air of this paddy part (i).
When throwing away in the flushing toiler with the state of as shown in Figure 64 doublings, 8 doublings, the paddy portion (i) of folding part L1 not only, and the part of the inboard of the cross section of folding part L1 and folding part L2 also exists air in (ii), and the air of this part (ii) is discharged into the outside of wiper blade at an easy rate from otch P3.Therefore, though wiper blade directly throw away in the flushing toiler with folding state, low because of buoyancy in water and purification tank, sink easily.
The centre position of the wire eyelet P1 that forms on the L2 of folding part also can form long otch P2 and P3.

Aforementioned interior lamellar body S1, outer lamellar body S2 and outer lamellar body S3 are got up by the adhesive bond of water-soluble or water-swellable equally with lamellar body S1 in aforementioned and outer lamellar body S2, and institute thinks the decomposable wiper blade of water.And, identical with lamellar body S1 in aforementioned with outer lamellar body S2, at each wiper blade S1, S2, S3 or be formed with many fine apertures 13 on lamellar body S2 and the S3 at least outside.This fine aperture 13 is identical with outer lamellar body S2 with lamellar body S1 in aforementioned, is that the wet type papermaking operation when making interior lamellar body S1 with outer lamellar body S2, S3 forms.
And interior lamellar body S1, outer lamellar body S2, S3 carry out wrinkle processing by drying drum shown in Figure 4 16 and winding drum 18.In wiper blade S1, S2 and S3, drying drum 16 is regulated the percentage of elongation of wiper blade with the rotary speed difference difference of winding drum 18,19 by the extent of this rotary speed.In the present invention, interior lamellar body S1 is identical with lamellar body S1 in aforementioned, and is little or be not formed with the wiper blade that wrinkle does not stretch for percentage of elongation.Outer lamellar body S2 is than the high wiper blade of interior lamellar body S1 percentage of elongation.Lamellar body S3 goes up the wrinkle of processing outside, makes outer lamellar body S3 than interior lamellar body S1 percentage of elongation height, and is lower than outer lamellar body S2 percentage of elongation.
Wiper blade 11 also is at interior lamellar body S1, under the overlapping state of outer lamellar body S2 and outer lamellar body S3, and the limit humidification, the limit is formed by junction surface a1 joint by heating plate pressurization shown in Figure 2.
The interior lamellar body S1 that is engaging like this, outer lamellar body S2 and outside impregnation contains water, alcohol, surfactant, anticorrisive agent and deodorant, aromatic and suppresses the metal ion etc. of wiper blade hydrolysis on the lamellar body S3 cleaning soup.When impregnation should be cleaned soup, the wrinkle that is formed on the wiper blade stretched.Because of the wiper blade percentage of elongation height of outer lamellar body S2 than interior lamellar body S1, outer lamellar body 2 is bigger than interior lamellar body S1 stretching, extension.Therefore as shown in Figure 9, in the row A1 and the zone between the A1 of junction surface a1, form bulge B1 outside on the lamellar body 2.Similarly, because the stretching, extension of wrinkle of formation on the outer lamellar body 3, the difference because of the wiper blade percentage of elongation of outer lamellar body S3 and interior lamellar body S1 between the row A1 and A1 of junction surface a1, also is formed with bulge B2 on the lamellar body S3 outside.
But the percentage of elongation of outer lamellar body S3 is littler than the percentage of elongation of outer lamellar body S2, and therefore, compared with the volume of the bulge B2 of outer lamellar body S2, the volume of the bulge B3 of outer lamellar body S3 is little.That is, compared with the volume of the space C1 between interior lamellar body S1 and the outer lamellar body S2, the volume of the space C2 between interior lamellar body S1 and the outer lamellar body S3 is little.
This wiper blade 11 is that the big outer lamellar body S2 of bulge B1 is used towards wiping thing.And outer lamellar body S3 also can use towards wiping thing.When being received into aforementioned wiper blade in the container, can make 11 the inside side of outer plate body S2 towards wiper blade, promptly outer lamellar body S2 gets up to take in facing to folded.In this case, when the user was used in cleaning to wiper blade 11 with the state of 4 doublings and 8 doublings, outer lamellar body S3 was towards the frequency of utilization height of cleaning piece side.The volume of the bulge B1 of the cause last formation of lamellar body S2 outside is big, can bring into play its wiping effect effectively, especially to more effective attached to the dirt on the face that convex-concave is arranged.
And this wiper blade 11 also can be used the inside conversely.When inside using conversely, its wiping effect is also fine.In this case, outer lamellar body S3 is the outside, and promptly the side towards cleaning piece is used.Even lamellar body S3 gets under the situation that the direction of thing is used towards wiping outside, because of should being formed with bulge B2 on outer lamellar body S3, the face side of this outer lamellar body S3 to wipe effect also good.But the volume of the bulge B1 of the outer lamellar body S2 of the volume ratio of the bulge B2 of outer lamellar body S3 is little, and therefore outer lamellar body S3 produces effect for wiping the dirt of being paid on the smoother face.Like this, the wiper blade of this example when cleaning, is used outer lamellar body 2 sides and is used outer lamellar body S3 side, can obtain different effects.
This wiper blade 11 is formed with bulge on the two sides, abundanter as a whole, take with hand easily, but the volume as the bulge B2 of the outer lamellar body S3 of the inside is low slightly, the volume of the volumetric ratio space C1 of space C2 do little, so, make the amount of the contained air of wiper blade 11 integral body do one's utmost to tail off.Therefore, in flushing toiler or in the clean water tank, wiper blade 11 does not have superfluous buoyancy, easily sinking.That is, when the volume of the bulge B1 of outer lamellar body S2 was made the suitable height that is used for wiping effectively dirt, the air capacity that contains in wiper blade 11 integral body diminished as far as possible.Can prevent that buoyancy from becoming big superfluously.
Particularly in Fig. 8 and the wiper blade 11 shown in Figure 9, because of interior lamellar body S1 and outside be formed with many apertures 13 on lamellar body S2, the S3.So in the water and purification tank of flushing toiler, the air in space C1 and the C2 is run away to the outside easily from aperture 13, thereby is sunken in the water easily.
As described above, the bulge B1, the B2 that go up formation for lamellar body S2 outside and outer lamellar body S3 have suitable space C1 and C2, and because of doing the bulge of outer lamellar body S2 greatlyyer than the bulge of outer lamellar body S3, the stretching, extension rate variance of the wiper blade that is caused by the stretching, extension of the wrinkle of lamellar body S1 in aforementioned and outer lamellar body S2 is preferably in 20%～80% the scope.And the stretching, extension rate variance of the wiper blade that stretching, extension caused of the wrinkle of interior lamellar body S1 and outer lamellar body S3 is preferably in 10%～50% scope, and the stretching, extension rate variance of the wiper blade of outer lamellar body S2 and outer lamellar body S3 is preferably in more than 10% even more than 20%.
When the former length of establishing lamellar body is X, float on the liquid, wrinkle is recovered, the sheet body length of lamellar body after stretching be Δ X, then the percentage of elongation of lamellar body of the present invention is ((Δ X-X)/X) * 100 (%).
In illustrated embodiment, be formed with many apertures 13 on the both sides of lamellar body S2 and outer lamellar body S3 at least outside.But, also can be only and interior lamellar body S1 between many apertures 13 of formation on the capacious outer lamellar body S2 of the space C1 that forms.Even on the whole lamellar body of lamellar body S1, S2, S3, do not form aperture 13,, still can bring into play the effect of the buoyancy that suppresses wiper blade 11 integral body because the volume of the space C2 between interior lamellar body S1 and the outer lamellar body S3 is done for a short time.
Wiper blade of the present invention as above is most lamellar bodies to be piled up and to form on lamellar body the wiper blade of bulge, thus remain in the hand easily, and the good effect of wiping is arranged.Because aforesaid bulge, though contain air between lamellar body and lamellar body, these air easily are rejected to the outside of lamellar body, so buoyancy is low in the water of flushing toiler and purification tank, what wiper blade became avales easily.
And when throwing away wiper blade in the flushing toiler with the state of 2 doublings, 4 doublings or 8 doublings, the air of the inboard of this folding part also is rejected to the outside easily, avales easily in flushing toiler and purification tank.
And, the wiper blade of additional embodiments of the present invention, promptly the volume of the last bulge that forms of lamellar body S2 is big outside for one side, and the volume of the bulge of the i.e. last formation of outer lamellar body S3 of another side is little, so the different face (outer lamellar body S2, outer lamellar body S3) with wiper blade can obtain the different effects of wiping.And, because of interior lamellar body S1 and outside between the lamellar body S2 and in lamellar body S1 and outside forming the space between the lamellar body S3, so the volume ratio of wiper blade integral body is abundanter.Interior lamellar body S1 and outside in the volumetric ratio in the space that forming between the lamellar body S3 lamellar body S1 and outside the volume in the space that forms between the lamellar body S2 little, so, can reduce the buoyancy of wiper blade in water.Therefore, this wiper blade grasps easily with hand, and is bringing into play various cleaning effect, avales easily in the time of in pouring toilet.
As above Shuo Ming wiper blade of the present invention, under the state that soaks peace and quiet soup, income is being used in the container of plastics, or the state that also can do is taken in the container and used.At this moment, also can be in use, the peace and quiet soup of impregnation is re-used as wet lamellar body and uses.Drying regime that can also the peace and quiet soup of not impregnation is used.In addition, the formation method of the bulge of wiper blade of the present invention is not limited to the method that forms by the stretching, extension rate variance between overlapping lamellar body.For example can be in advance form the bulge of convex-concave, partly be bonded on this lamellar body again by ripple processing (colgateprocess) etc.In this case, between junction surface and junction surface, on lamellar body, can form bulge.
