201233376 六、發明說明： 【發明所屬之技術領域】 本發明係關於一種伸縮性片體之製造方法。 【先前技術】 就儘量減省材料、儘量抑制廢棄物、有益於環境、抑制 成本這一觀點而言’已知有預先於另一步驟中製造包含系 固帶之腰部翼片材，對包含吸收體之長方形狀之吸收性本 體附加該腰部翼片材而製造之展開型一次性尿片。就穿戴 性之觀點而言’腰部翼片材較佳為伸縮性之構件，作為腰 部翼片材，一般而言使用利用伸縮性之膜而形成者。然 而’由於伸縮性之膜之成本花費較大，故較佳為使用通用 之彈性構件即所謂橡膠線而形成腰部翼片材。但，於一系 列流程中連續地實施使用橡膠線而獲得腰部翼片材之步 驟、及將該腰部翼片材附加於吸收性本體而獲得展開型一 次性尿片之步驟的情形時，使用橡膠線而形成之腰部翼片 材之伸縮方向一般而言係與吸收性本體之搬送方向為相同 方向，成為與穿著展開型一次性尿片時所需之腰部翼片材 之伸縮方向正交之方向。因此，於在連續式步驟中將使用 橡膠線而形成之腰部翼片材附加於吸收性本體而製造展開 型一次性尿片的情形時，必需使利用橡膠線而形成之腰部 翼片材反轉90度’再附加於吸收性本體。如此，由於另外 需要使腰部翼片材反轉9〇度之裝置，故將導致設備投資之 增大。 作為不使用如上所述之使腰部翼片材反轉9〇度之裝置之 159664.doc 201233376 方法，例如，於專利文獻1、專利文獻2甲記載有進行如下 兩個步驟之伸縮性片體之製造方法：於沿長度方向運行中 之透水性片體上塗佈接著劑’使對該接著劑塗佈面賦予張 力之線狀彈性體沿運行之片體之片體面且朝向片體運行方 向地在鋸齒形狀態下平行移動，從而使該線狀彈性體於伸 長之狀態下與片體接著；及於兩端切割上述線狀彈性體。 又，於專利文獻1中亦記載有將鋸齒形狀態之線狀彈性體 重新平行配置之方法。 然而，關於專利文獻1及專利文獻2中所記載之切割步驟 中所使用之切割器，難以將線狀彈性體之兩端各自之不需 要之部分切割得一樣短，而使所製造之伸縮性片體變得不 美觀。又，於專利文獻1及專利文獻2中，對於將線狀彈性 體之兩端各自之不需要之部分切割得一樣短之方法，除僅 配置輥切割器以外’未揭示有其他任何方法。 又，於專利文獻1、2所記載之技術中，線狀彈性體中之 伸長狀態被解除而使自帶狀片體之寬度方向之端緣延伸出 之部分以朝向不規則之方向之狀態保留，由此導致所製造 之伸縮性片體變得不美觀。 先前技術文獻 專利文獻 專利文獻1 :曰本專利特開昭63-243309號公報 專利文獻2:曰本專利特開2〇1〇_22588號公報 【發明内容】 發明所欲解決之問題 159664.doc 201233376 本發明之課題在於提供一種可消除上述先前技術所存在

兩外側之切割器接收部187、187各自之z方向之上方側， 配置有線狀彈性體7之按壓帶191、191。由於按壓帶19ι、 1 91係左右對稱地形成，故於以下之說明中，對一按壓帶 191進行說明》 如圖4所示，按壓帶191係架設於旋轉軸方向配置為X方 向之滑輪191 a、191 b、191 c間。滑輪191 a係位於石占報184 之下游側’滑輪191c係位於砧輥184之上游側，滑輪19lb 係位於滑輪19 1 c之上游側。滑輪1 91 a之z方向之下端及滑 輪191c之z方向之下端係位於較砧輥184之z方向之上端更 下方處。因此，如圖4所示，架設於滑輪191a、191b、 191c間之按壓帶191係遍及砧輥184之切割器接收部187之 外周之一部分之區域而接觸，且隨著砧輥184之旋轉而連 帶轉動。 如圖2所示，製造裝置11A包括吸引部195、195，該吸引

接下來，對使用上述製造裝置11A而製造伸縮性片體之 方法進行說明。 首先’如圖3所示，連續地放出線狀彈性體7，將經放出 之線狀彈性體7導入至彈性體捲繞用之旋轉臂14(供給步 驟）。若詳細敍述’則係使用放出輥152而自纏繞有線狀彈 性體7之線軸70連續地放出線狀彈性體7。於放出時，根據 藉由張力測定器153而進行之線狀彈性體7之張力之檢測輸 出’藉由製造裝置11所具備之控制部（未圖示），而控制捲 出親152之旋轉速度’以特定之張力自線軸7〇放出線狀彈 性體7。 繼而’將線狀彈性體7導入至旋轉臂14。於導入時，藉 由進料輥156 ’以藉由旋轉臂14而將線狀彈性體7捲繞至一 對搬送帶12、13之捲繞速度以上之速度，將藉由緊張器 151及放出輥152而伸長至特定之伸長應力的線狀彈性體7 供給至旋轉臂14。此處，所謂「捲繞速度」係指用環繞搬 送帶12(上層搬送帶12a、下層搬送帶12b)之外周側及搬送 帶13(上層搬送帶13a、下層搬送帶i 3b)之外周側丨周之線狀 彈性體7之長度除以環繞丨周所需要之時間而獲得的值。 繼而’如圖2、圖4所示’使用旋轉臂μ將線狀彈性體7 連續地捲繞至一對搬送帶12、13，並藉由一對搬送帶12、 159664.doc -19· 201233376 13而搬送線狀彈性體7(搬送步驟）。若詳細敍述，則係使於 伸長狀態下供給至旋轉臂14内之線狀彈性體7自導入口 145 導入至臂部141内，並通過軸部142、連結部144及環繞部 143内而自導出口 146導出。自導出口 146導出之線狀彈性 體7係藉由一面使旋轉臂14旋轉、一面導出，而捲繞至搬 送帶12(上層搬送帶12a、下層搬送帶12b)之上游側之端部 之外周側及搬送帶13(上層搬送帶i3a、下層搬送帶i3b)之

此處’捲繞至一對搬送帶12、13之線狀彈性體7係沿與y 方向交又之方向伸長，而未配置在與y方向正交之方向。 為了將經捲繞之線狀彈性體7修正為與y方向正交之方向（χ 方向）’例如’如圖2所示，於捲繞線狀彈性體7之情形 時’於搬送帶12中，使上層搬送帶12a之旋轉速度慢於下 層搬送帶12b之旋轉速度，於搬送帶13中，使下層搬送帶 13b之旋轉速度慢於上層搬送帶Ua之旋轉速度，藉此，於 朝向y方向之搬送中，使線狀彈性體7之斜度逐漸變化，直 到搬送至一對帶狀片體50、60之間之前，可將線狀彈性體 7之斜度修正為與^^方 向正交之方向（X方向）。 159664.doc 201233376 如圖2所示’帶狀片體50係預先藉由翻折導引件（未圖 示）等而使X方向之兩端部各自向外表面側折起，而自搬送 帶12(上層搬送帶12a、下層搬送帶12b)及搬送帶13(上層搬 送帶13a、下層搬送帶13b)之上層側供給至一對乳輕pi、 172之間。又，如圖2所示，帶狀片體60係預先藉由翻折導 引件（未圖示）等而使X方向之兩端部各自向外表面側折起， 而自搬送帶12(上層搬送帶i2a、下層搬送帶i2b)及搬送帶 13(上層搬送帶13a、下層搬送帶13b)之下層側供給至一對 軋輥171、172之間。再者，帶狀片體5〇及/或帶狀片體6〇 係於供給至一對軋輥171、172之間之前，於其内面側塗佈 有接著劑。接著劑之塗佈既可對整個面呈螺旋狀塗佈，亦 可呈面狀或條紋狀地塗佈。 繼而，使用軋輥1 7 1、1 72將線狀彈性體7以伸長狀態固 定於一對帶狀片體50、60之間（一體化步驟）。於一體化步 驟中，於將線狀彈性體7捲繞至一對搬送帶12、13之狀態 下將線狀彈性體7黏貼於帶狀片體50、60之間。若詳細敍

繼而’切割自一對帶狀片體50、60之寬度方向（X方向） 159664.doc -21 - 201233376 兩端部各自延伸出之線狀彈性體7之部分（切割步驟）。於切 割步驟中，使用配置於一對搬送帶丨2、丨3之内側部分之切 割機構（壓切式縱切輥183、砧輥184)，於線狀彈性體7捲繞 至一對搬送帶12、13之狀態下切割線狀彈性體7。又，於 切割步驟中’使用僅自上方向按壓延伸出之線狀彈性體7 之部分之機構，一面保持伸長狀態，一面進行切割，而將 線狀彈性體7之延伸出之部分去掉。若詳細敍述，則係如 圖2所示，藉由包括切割刀185之壓切式縱切輥ι83及砧觀 184 ’而於線狀彈性體7捲繞至一對搬送帶12、13之狀態 下，對位於較帶狀片體50、60之\方向兩外側端各自更靠 外側之線狀彈性體7之部分即未固定於一對帶狀片體5〇、 60間之線狀彈性體7、亦即線狀彈性體7之剩餘部分進行切

Description of the Invention: [Technical Field of the Invention] The present invention relates to a method of manufacturing a stretchable sheet. [Prior Art] In view of minimizing material reduction, minimizing waste, benefiting the environment, and suppressing costs, it is known that a waist-wing sheet comprising a fastening tape is manufactured in advance in another step, and contains absorption. An unfolded disposable diaper manufactured by attaching the waist flap sheet to the rectangular absorbent body. From the viewpoint of wearability, the waist flap sheet is preferably a member having stretchability, and as the waist flap sheet, a stretchable film is generally used. However, since the cost of the stretchable film is large, it is preferable to form a waist fin sheet using a so-called rubber thread which is a general elastic member. However, in the case where the step of obtaining the waist flap sheet using the rubber thread and the step of attaching the waist flap sheet to the absorbent body to obtain the unfolded disposable diaper are continuously performed in a series of processes, rubber is used. The direction in which the waist flaps are formed by the thread is generally in the same direction as the direction in which the absorbent body is conveyed, and is oriented orthogonal to the direction in which the waist flaps are required to be worn when the disposable diapers are worn. . Therefore, in the case where the waist-shaped flap sheet formed by using the rubber thread is attached to the absorbent body in the continuous step to manufacture the unfolded disposable diaper, it is necessary to reverse the waist flap sheet formed by the rubber thread. 90 degrees' is added to the absorptive body. As a result, there is an additional need to reverse the waist flap sheet by 9 degrees, which will result in an increase in equipment investment.

The slit roller 293 and the anvil roll 294 cut the unnecessary portion 272 of the linear elastic body 7 extending from both ends of the pair of strip-shaped sheets 50 and 60 in the width direction. The suction portion 296 is disposed close to a portion where the cutter blade 295 is in contact with the circumferential surface of the anvil 294. Next, a method of manufacturing a stretchable sheet using the above-described manufacturing apparatus 11 or the like will be described. First, as shown in Fig. 3, the linear elastic body 7 is continuously discharged, and the discharged linear elastic body 7 is introduced into the rotating arm 14 as an elastic body winding mechanism in an extended state. As will be described in detail, the linear elastic body 7 is continuously discharged from the bobbin 70 of the wound linear elastic body 7 by using the discharge roller 152. In the present embodiment, the bobbin 70 is not rotated, but may be a rotatable person. At the time of release, the detection output of the tension of the linear elastic body 7 by the tension measuring device 153 is adjusted by the control unit (not shown) of the manufacturing apparatus 11 to adjust the rotation speed of the winding roller 152 or The tension of the tensioner 151 releases the linear elastic body 7 from the bobbin 70 with a specific tension. Further, in the present embodiment, the linear elastic body 7 is introduced into the rotary arm 14, and the linear elastic force introduced into the rotary arm 14 (elastic winding mechanism) by the feed roller 156 at the time of introduction is introduced. The speed of the body 7 is adjusted to a fixed speed and introduced. The introduction speed is set to a speed corresponding to the winding speed of the pair of conveyor belts 12, 13. Then, as shown in FIGS. 16 and 3, the linear elastic body 7 in the extended state is continuously wound around the pair of conveyor belts 12 and 13 by using the rotary arm 14, and a pair of conveyor belts 12 are used, 159664.doc 201233376, The linearly wound linear elastic body 7 is conveyed between the pair of belt-like sheets 50 and 60. When it is described in detail, the linear elastic body 7 supplied to the rotating arm 14 in the extended state is introduced into the arm portion 141 from the introduction port 145, and is guided by the shaft portion 142, the connecting portion 144, and the surrounding portion 143. Export 146 is exported. The linear elastic body 7 which is led out from the outlet 146 is wound around the end of the upstream side of the conveyance belt i2 (the upper conveyance belt 12a and the lower conveyance belt 12b) by rotating the rotary arm 14 while being rotated. The side and the upstream side of the upstream side of the conveyance belt 13 (the upper conveyance belt 13a and the lower conveyance belt 13b) are the outer peripheral side. Here, the linear elastic body 7 can be continuously spiraled by the rotation operation of the conveyance belt 12 (the upper conveyance belt 12a and the lower conveyance belt 12b) and the conveyance belt 13 (the upper conveyance belt i3a and the lower conveyance belt 13b). It is wound around the outer peripheral side of the conveyance belt 12 (the upper conveyance belt 12a and the lower conveyance belt 12b) and the outer side of the conveyance belt 13 (the upper conveyance belt i3a and the lower conveyance belt 13b). The continuously wound linear elastic body 7 is conveyed to between the pair of belt-like sheets 50 and 60 on the downstream side. Here, the linear elastic body 7 wound around the pair of conveyor belts 12, 13 is elongated in the direction crossing the y direction and is not disposed in the direction orthogonal to the y direction. In order to correct the wound linear elastic body 7 to a direction orthogonal to the 7 direction (X direction), for example, as shown in FIG. 6, when the linear elastic body 7 is wound, the conveying belt 12 is used. In the middle, the rotation speed of the upper conveyance belt 12a is slower than the rotation speed of the lower conveyance belt 12b, and the rotation speed of the lower conveyance belt 13b is slower than the rotation speed of the upper conveyance belt 13a in the conveyance belt 13, whereby the orientation is y In the direction of conveyance, the inclination of the linear elastic body 7 is gradually changed until the conveyance is carried out between the pair of belt-like sheets 5〇, 6〇, and the thread 159664.doc • 42· 201233376 Elastomer 7 can be used. The inclination is corrected to the direction 0 which is orthogonal to the direction of the other direction. As shown in Fig. 16, the strip-shaped sheet 5 is previously provided by the seller (not shown) or the like at both ends in the longitudinal direction (both ends of the X direction). Each of the outer surface side (the non-opposing surface side that does not face the strip-shaped sheet body 60 and does not face) is folded up, and the self-moving-feeding belt 12 (the upper layer conveying belt 12a and the lower layer conveying belt 12b) and The upper belt side of the conveyor belt % upper conveyance belt 13a and the lower layer conveyor belt 13b) is conveyed between the pair of rolls 171 and 172. In addition, as shown in Fig. 16, the strip-shaped sheet body 6 is previously provided on the outer surface side (not in the strip shape) on both sides in the longitudinal direction (both ends in the χ direction) by a seller (not shown) or the like. The sheet body 50 is folded up toward the non-opposing surface side, and is supplied to the lower layer side from the conveyance belt 12 (the upper conveyance belt i2a and the lower conveyance belt i2b) and the conveyance belt 13 (the upper conveyance belt 13a and the lower conveyance belt 13b). A pair of rolls 171, 172. Further, the strip-shaped sheet body 5 and/or the strip-shaped sheet body 6 are coated with an adhesive on the inner surface side before being supplied between the pair of rolls 171 and 172. The coating of the subsequent agent can be applied to the entire surface in a spiral shape or in a full surface. Then, the linear elastic body 7 is fixed in an extended state between the pair of belt-like sheets 50 and 60 by the rolls 171 and 172. As will be described in detail, a continuous body in which the linearly wound elastic body 7 is disposed between the pair of belt-like sheets 50 and 60 is supplied between a pair of rolls 171 and 1 72, and is linear. The elastic body 7 is fixed between the pair of belt-like sheets 50 and 60 in an extended state. As described above, the linear elastic body 7 is wound up to a pair of transport belts 2, 13 in a direction orthogonal to the transport direction of the sheets 50, 60 (X direction), and by a pair After the conveyance belts 12 and 13 convey the wound linear elastic body 7, the linear elastic body 7 is sandwiched between the strip pieces 159664.doc 43·201233376 bodies 50 and 60 by using the rolls 171 and 172 as described above. The step of fixing is a fixing step (integration step) in the present embodiment. Then, the linear elastic body 7 extending from both end edges in the width direction (X direction) of the pair of strip-shaped sheets 5 〇 and 6 〇 is cut by the cutter 18 (first cutting step). In the i-th cutting step, the linear elastic body 7 which is stretched between the pair of conveyor belts 12 and 13 and which is in an extended state is cut, and the winding of the linear elastic body for the winding of the pair of conveying belts 2, 3 is released by the cutting. In the state of the linear elastic body 7, the stretchable sheet body 3A extending from both end edges in the width direction of the strip-like sheets 50 and 60 is obtained. The stretchable sheet body 3A is in a state of being contracted (natural state) in a portion in which both end edges of the strip-shaped sheets 50 and 60 in the width direction extend. Further, in the present embodiment, the both sides of the strip-shaped sheet 5's and 6'''''''''''' Then, the stretchable sheet body 3A is conveyed to the second cutting mechanism 219, and the self-retaining sheet body 50 of the linear elastic body 7 of the stretchable sheet body 3 is removed by cutting by the second cutting mechanism 219. And the whole or a part of the contracted portions 272, 272 extending from both end edges of the width direction of 60. As shown in Fig. 17, in the second cutting step of the present embodiment, only the linear elastic bodies 7 in the y direction of the stretchable sheet body 3A are cut only in the width direction of the strip-shaped sheets 50, 60. The part of the edge extends. If it is described in detail, as shown by the circle 17, the cutting edge slitting roller 293 and the anvil roller 294 including the cutting blade 295 are cut at the outer ends of the belt-like sheet 5〇, 6〇. The portion of the linear elastic body 7 which is further outside is not fixed to 159664.doc -44 - 201233376. The linear elastic body 7 between the pair of strip-shaped sheets 50, 60, that is, the remaining portion of the linear elastic body 7 . This cutting is performed in a state in which the sheet portion (belt-like sheets 5〇, 6〇) in the stretchable sheet 3A is also in the width direction by the linear elastic body 7 except for the linear elastic body 7. shrink. However, the stretched state of the strip-like sheets 50 and 60 can be maintained and transferred directly to the second cutting mechanism. In this state, the contracted portions extending from the both end edges in the width direction of the strip-shaped sheets 50 and 60 can be cut. 272. By the second cutting step, the contracted portion 272 extending from both end edges in the width direction of the strip-shaped sheets 5 and 6 is cut, whereby the two portions of the linear elastic body 7 are unnecessary. Partially cut and removed in the same way to enhance the aesthetics of the manufactured stretchable sheet. Moreover, by providing the suction portions 296 and 296', it is possible to prevent the dicing sheet which is generated by the cleavage from entering the stretchable sheet body 3 of the linear elastic body 7 or adhere to the rollers 293 and 294 due to the dicing. . In the second cutting step, it is preferable to prevent the linear elastic body 7 of the stretchable sheet 3A after the fixing step from being cut from the viewpoint of preventing the appearance of the stretchable sheet 3 from being deteriorated due to the extension portion described below. The length L1 of the portion extending from the both end edges in the width direction of the strip-shaped sheet is 0 to 5 mm, particularly 0 to 3 mm. It is also possible to cut the linear elastic body 7 at substantially the same position as the both end edges in the width direction of the belt-like sheets 5, 6, and completely eliminate the portion of the linear elastic body 7 extending from the both end edges. Then, at both ends in the width direction (both ends in the X direction) of the strip-like sheets 50 and 60 which are folded outward on the outer surface side by a seller (not shown), the width is 159664.doc -45- 201233376 is spread out to the outside, and the respective developed portions are joined to each other by a well-known joining method such as an adhesive or a fusion. By this, the linear elastic body 7 can be continuously fixed between the pair of belt-like sheets 50 and 6 to be stretched in a state in which the linear elastic body 7 is elongated in a direction intersecting the 丫 direction. Further, the above-described belt-shaped stretchable sheet body is intermittently cut in the X direction by a well-known cutting mechanism (not shown). The interval of intermittent cutting is the same as the size of the diaper 1, including the waist flaps 3. Thereby, the waist flap 3 (stretchable sheet) can be continuously manufactured. According to the sixth embodiment, after the first cutting step of releasing the wound state of the linear elastic body 7 with respect to the pair of conveying belts 12 and 13, the linear elastic body is cut in another step different therefrom. 7 is a whole or a part of the constricted portions 272, 272 extending from the opposite ends of the strip-shaped sheet body in the width direction, so that the strip-shaped sheet bodies 5 〇 and 6 〇 can be efficiently removed from both ends of the width direction. The unstable portion of the linear elastic body is used to efficiently produce the stretchable sheet 3 having a good appearance. Further, when the cutting of the linear elastic body 7 for the winding state of the pair of conveying belts 12 and U is performed, it is necessary to cut the portion extending from both end edges in the width direction of the self-belt sheet. After the linear elastic body is maintained, the cutting is performed while the next linear elastic body is not contracted, and the structure of the cutting mechanism is complicated. On the other hand, as in the present embodiment, the cutting of the linear elastic body for releasing the winding state of the pair of conveying belts 12, 13 and the cutting of the unnecessary portion are performed in another step. The short cut can prevent the expansion of the stretchable sheet, and it is also complicated to manufacture the stretchable sheet which has a good appearance and removes the unnecessary portion. In the sixth embodiment, the strip-shaped sheet body 50 which is folded into a narrow width toward the outer surface side (non-opposing surface side) is used. After the fixing step, the i-th cutting step, and the second cutting step are performed, the respective folded portions of the strip-shaped sheets 5 and 6 are unfolded, and a pair of the unfolded portions of the strip-shaped sheet are unfolded. Then, as shown in Fig. 17, the stretchable sheet 3 in which the linear elastic body 7 is not extended from both ends of the strip-shaped sheet body is obtained. Therefore, even in the second cutting step, the constricted portion 272 of the linear elastic body 7 is cut so as to retain a portion in which the both end edges of the self-contained sheet body extend in the width direction, in the finally obtained stretchable sheet body 3. The extension is also almost inconspicuous. As a manufacturing method of the urine R including the waist flap 3, a continuous body of the absorbent body 2, a continuous system of the absorbent body 2, and a continuous body of the front sheet 21, is manufactured in another step by a well-known method. The plurality of absorbers 23, 23, . . . are disposed intermittently along the transport center direction of the continuous body of the back sheet 22 and the continuous body of the two sheets 21 and 22, and are arranged continuously along the sheet body 21. A plurality of elastic members 25 and a continuous body of the three-dimensional protective forming sheet 24 which are elongated on both sides of the transport direction (y direction) of the body. The continuum of the diaper 如下 which is the following: the continuous body of the absorbent body 2 manufactured in the direction of the transport direction is transported to the continuum of the absorbent body 2 in such a manner as to extend outward in the X direction Each of the absorbent bodies 23 included in the body is provided with a pair of waist flaps 3. By forming the waist flap 3' from the stretchable sheet produced in the above manner, it is easy to prevent the linear elastic body 7 from being present at the joint portion of the absorbent body 2, and also has a seal. The advantage that sex becomes good. Here, the direction in which the continuous body of the absorbent body 2 is conveyed is the same direction as the direction in which the waist flap 3 (the stretchable sheet body is formed), and it is not necessary to reverse the waist flap 3 (stretchable sheet). Turn 9〇. . Thereafter, the continuum can be cut into the size of each diaper by a well-known cutting mechanism (not shown) to produce a diaper. Next, a seventh embodiment of the present invention will be described. The seventh embodiment is mainly described with respect to the sixth embodiment, and the same reference numerals will be given to the same points, and the description will be omitted. The aspect which is not particularly described can be set to be the same as the above embodiment. As shown in Fig. 18, in the seventh embodiment, as the second cutting mechanism, a plough head cutter 219 which includes two or more sliding knives which are moved by one or both sides is used. The ploughshare cutter 219 is disposed on both sides of the elastic sheet 3, and respectively, as a pusher, sandwiches the linear elastic body 7 between the two knives to apply a shearing force to the linear elastic body 7 The cutting is performed, and in the seventh embodiment, the same effects as those in the sixth embodiment can be obtained. The method for producing the stretchable sheet of the present invention is not limited to the above-described first, second, third, fourth, fifth, sixth, and seventh embodiments, and can be appropriately changed. For example, in the manufacturing apparatuses UA, 11B, and 11D used in the manufacturing methods of the first, second, and fourth embodiments, the pressing belt 191 is provided as a mechanism from the vertical direction to the third and fifth. In the manufacturing apparatuses 11C and 11E used in the manufacturing method of the embodiment, the upper and lower belts 193 and 194 are provided as the mechanism for pressing from the vertical direction, and may be replaced by _48·159664.doc.
