200831272 九、發明說明： 【發明所屬之技術領域】 本發明係有關預先設置彎曲促進部之薄片折彎裝置。 【先前技術】 在紙或樹脂等的箱、袋及薄資料盒等的製造，會進行 成爲原材料之薄片的折彎加工。在那情況，除非是特殊物； 品，否則通常都是以自動化生產線來進行。因此有需要補 齊可確保折彎部之反覆位置的精度，並使其折彎後之彎曲 角度的變動縮小而使折疊變得容易之設備。又，薄片本身 也爲了容易進行在一定位置的折彎，而在折彎部分設置促 使折彎加工的部分（以下稱爲彎曲促進部）。例如，沿著 薄片的折彎線施作格線狀的凹陷或設置開口的部分（以下 稱格線）。像這種薄片，有（1)如電子電路、裝飾畫般以印 刷等的手段形成賦予機能之層（以下亦稱機能部）者，與 (2)像資料盒等僅由薄片所形成者。尤其是前者的情況，對 於形成在薄片之機能部不會有不良影響，且有效地活用並 有效率地折彎乃是重要的。 在習知之折彎手段，係有將薄片分割成規定之形狀單 位而一片一片進行的情況，與不分割而供給束成複數片或 長條薄片連續進行的情況。前者之例可列舉有使用切具 (chopper)方式、抵碰三角之模型板的腹板方式及旋轉台方 式。又依據彎曲的難易度有各種的手段。例如屬難以彎曲 的材料之樹脂與金屬疊層的複合材料，係被掛在鉗輥子（nip roller)而藉由模型成形。 200831272 在專利文獻中介紹有幾個高精度進行折彎用的手段。 例如，特開平7 — 1 86307號公報（專利文獻1 )，係介紹一 面供應長條薄片一面以模型折彎成形的例。此例係不設置 蛇行修正機構而按壓薄片的蛇行，以確保折彎位置之反覆 精度的手段。尤其寬度小的薄片在折彎部分的兩側由於原 材料與模型壁之密接阻力大，所以在其兩側產生折彎阻力 的不平衡，容易偏向該阻力大的那一側。因此以多數的輥 子導引將折痕正確地放在模型板的V字型的尖端而折彎。 又特開平7 — 3 3 0206號公報（專利文獻2)，係介紹折彎後 恢復力強的紙或樹脂製之箱的折彎事例。係一面以開口帶 或輥子壓住彎曲部一面回避彎曲之恢復，使薄片被帶子夾 住而作水平移動。在其狀態下賦上薄片黏著層，一面緩慢 的按壓以輥子與扭旋帶將薄片折彎折疊接合。將該等一連 串的動作簡化地匯集之設備的例子。更在特開平9 - 26797 1 號公報（專利文獻3)介紹了僅以鉗輥子無法在紙、合成 紙、金屬箔等的薄片賦上充分的折痕之手段。薄片係以導 引板及導引輥子折半，預先在折痕附近加熱（80〜120 °C) 後，沿著折痕以輥子夾住加壓而可賦予折痕。 此外，在難以賦予折痕之原材料，要賦予折彎促進部 (格線等）。例如，賦予剖面爲V字形或梯形狀的溝槽者、 縫紉針孔狀或長孔斷續狀之穿孔型者、於溝槽的底部賦予 凹凸者、及賦予接近之平行溝槽者等，該等主要以直線狀 排列者較多。此外特開2004 — 243716號公報（專利文獻 4 )，係介紹在面內以波浪型而於厚度方向具有賦予一定深 200831272 度之折彎格線的樹脂薄片。依此，變得更容易彎 在較堅硬的樹脂上容易發生之由於折彎所產生之 向的運搬損傷較難發生。如此，折彎促進部的形 別依照製造業或實用上的目的而有各式各樣。 專利文獻1 :日本專利特開平7 —

度的拉緊狀態移動。又，以全部都朝圖之進深 薄片的全長或複數點的狀態，在被搬上台座途 。薄片係以 θ著格線折 形且在中央 2Β圖及第 13 ’可以是 是無機能部 有小孔或起 或曲線狀任 ‘料爲樹脂、 只要具有柔 性之折彎後 而把材料承 。然而，薄 自動化。 1圖加以說 持薄片運送 丨持部。從右 離開，而固 方向廻旋一 之另一方的 水平且以適 方向可把持 中的薄片， 200831272 係被保持平坦的面，可抑制移動中之薄片的變形。因此’ 被蒸鍍在薄片面上之薄膜或被印刷之厚膜等的機能部’不 會受到損傷。此外驅動軸係沿著軌道35移動’把持部係以 驅動軸爲中心可水平旋轉同時可沿著驅動軸朝垂直方向上 下移動。 廻旋式台座2係爲，在薄片座落於此且被固定之前， 廻旋部如虛線所示般以廻旋軸27爲中心而開啓的狀態。薄 片係從把持部31與未圖示之另一方的把持部被放開且跨 越固定台座21與廻旋台座22而座落。此外，在此例中係 於廻旋台座賦予朝向左邊變高般地傾斜，薄片係碰到固定 台座之右端的堤2 3而被定位。此外，在固定台座之左端也 設置有定位用的堤24。薄片之定位手段除了堤以外還有各 式各樣者。例如，亦可在薄片之端部開設複數個定位用孔， 使與台座相同形狀之凸出部嵌合。再者，在連續供應薄片 之需要高速定位的情況，也可用光學手段把台座與薄片進 行對位。 承載薄片之台座的面，例如，係以像多孔質的陶瓷材 料、多孔質的碳材料及陶瓷製靜電夾頭材料來形成期望之 平滑的座面者爲宜。據此，可防止吸附時薄片的損傷。薄 片係以維持台座面的傾斜方向與其彎曲促進部正交般而把 持的拉緊狀態座落。接著薄片被設置於台座上之未圖示的 吸附機構所密接固定，如圖所示廻旋台座在箭頭方向廻 旋’使薄片1被折彎。已折彎至規定角度之薄片係如圖所 示般被驅動軸34的把持部32所把持，且透過下一個折疊 -10- 200831272 手段4(在此圖中爲輥子方式）而被折疊。 絕緣材料的薄片，在其表面容易積存靜電。於折彎台 座之表面爲絕緣材料的情況，在台座表面容易積存靜電。 在這樣的情況時，帶電之薄片折彎後，透過靜電而連同台 座一起恢復，有招致在下一個折疊帶來障礙的情況。彈性 大的薄片其傾向尤其強。再者，折彎後暫時重疊放在一起 時，亦會因薄片間的靜電而有難以分離的情況。如此，當 薄片的面或是其接觸的面有帶電時，薄片相互因靜電而容 易附著或恢復到折彎前的狀態。因此會有薄片間的分離或 維持彎曲狀態出現障礙的情況。爲了防止這種困擾，宜在 折彎前將薄片面或其接觸面施以暫時的除電手段，或施以 永久防止帶電的手段。但於薄片上設置有機能部時，有需 要採取對其機能無不良影響的防止手段。在除電處理方 面，例如有，依照帶電狀況，把被離子化之空氣吹上的方 法、噴霧含有聚乙二醇等的吸濕成分及促使離子化之臭化 鉀等的液體之方法、及將含有界面活性劑之帶電防止劑噴 吹於目的表面的方法。吸濕成分係基於親水化的吸濕作用 而防止再帶電。永久性防帶電的帶電防止處理，例如有將 金屬或碳等之導電體蒸鍍於目的表面上之方法。據此以提 高表面的導電性，防止再帶電。若對折彎前之薄片一方的 面及與此接觸之台座面施以像上述之處理時，則可達成目 的。 此外，在此例中，薄片係水平移動，但本發明之裝置的 其他例’亦可使其上下方向自如地移動。又台座面的朝向 .200831272 也可改變自如。例如，亦採用在使其傾斜之台座上，使薄 片從上部沿著其內壁滑進，抵住下部的堤等而定位後，立 即以保持手段使其密接於內壁之手段。如此的三維配置， 雖也依薄片的形狀或機能部的形態而定，但較適合紙等尤 其是薄片厚的折彎。 ’ 第3圖係顯示用以折彎此例之矩形薄片之本發明裝置 的廻旋式台座之一例的圖。此外薄片係從第3圖之右下朝 箭頭方向送進。圖中之2 1至27係依號碼順序，爲運送方 向面前側的固定台座、運送方向深處側的廻旋台座、安裝 在固定台座的堤、安裝在廻旋台座的堤、固定台座面、廻 旋台座面及廻旋軸。 在第2A圖之形態的薄片之例，係使形成於其彎曲促進 部之折痕的格線與台座之中央的軸線能一致般地以拉緊的 狀態座落。接著以把持部3 1把持薄片之一邊的端的狀態下 從另一端的把持部被放開。此外在座落的同時薄片（未圖 示），係透過被設置在台座之真空吸附等的保持手段，被 以整面拉緊的狀態密接保持在規定的位置。之後立即從把 持部將薄片放開，把持部向第1圖之右方移動並退到從台 座離開的位置。此外，在將未具有彎曲促進部之薄片密接 保持在台座的情況，成爲需要用以去除實際折彎位置之偏 差的手段。例如有，在薄片之端部定位密接保持之後，沿 著折彎線把施加有拉力的金屬線從上方接觸而按住的方 法。在那種情況下，涵蓋線的全長將其剖面作成向下凸的 橢圓狀，亦可使其凸出部抵碰於折彎部之狀態。又例如， -12- 200831272 彎曲後之恢復較弱的薄片’亦可將其端部定位保持密接之 後’沿著台座的廻旋軸線真空吸引強制吸附。再者例如， 若爲不影響機能部的程度時，亦可使用線狀的加熱器適度 地間接加熱’或使用中央的吸引孔與冷媒或濕氣線狀接觸 而促使彎曲。接著如第1圖所示，台座向箭頭方向緩慢廻 旋。透過此，循著與廻旋台座22同樣的軌跡而將台座面的 薄片折彎。此外，薄片折彎後的內角，若考慮截至下個折 疊過程之間的運送中之恢復時，則以小於1 5度爲佳，更理 想是小於1 0度。 第4圖係按折彎階段來說明本發明之薄片的折彎機構 例的圖。1爲上述長方形的薄片，且在折彎前的狀態下承 載於廻旋式台座2。此圖係顯示第3圖之台座的A—A，剖 面者，係以薄片的寬度方向爲正面而描畫，進深方向爲長 度方向。雖未圖示，但在薄片的中央形成有用以促進折彎 的格線。在台座2設置有用以將薄片之端部抵碰兩端並定 位之堤23及24’在中央部有用以使台座廻旋之未圖示的廻 旋軸。台座係以此軸爲支點如第4C圖所示般地廻旋而把薄 片折彎。薄片所接觸的台座面如圖所示從正面看來係向右 下方變低般地傾斜。此斜面亦可爲平坦的面。在此圖之例 中，係在軸左方之廻旋台座22形成凹狀曲面的斜面。此外 該傾斜倒未圖示，係可透過內裝於廻旋台座之升降機構而 傾斜成最適當角度。 虛線部2 8，係形成於台座之面方向的間隙（以下也稱 溝槽）及與此相連的真空吸引孔。此外在圖中之溝槽的深 200831272 度係誇大地描畫，只要是薄片厚度之0.3至1倍左右即可。 又橫剖面乃描畫成矩形狀，但爲了減少與平坦之薄片的接 觸變形，亦可在角上施以倒角而以流暢的橫剖面連繫。要 將溝槽的深度設成此範圍是因爲在其小於薄片厚度之〇.3 倍時，吸引阻力會增加尤其在厚的薄片容易發生吸附力不 足，另一方面若超過1倍時，則薄片吸附時容易變形的緣 故。因此脫離此範圍薄片容易產生變形，而容易損傷到機 能部。29爲中央的真空吸引孔。在包含被設置於溝槽28 ❿ 之底的吸引孔28之路徑朝第4B圖之箭頭所示之下方吸 引，使薄片被吸附在台座面。此種情況，使台座表面成爲 多孔質，經由其通氣孔亦可吸引。此外，於格線部具有凸 出部的情況時，爲了避開凸出部的底端亦可在吸引孔的上 端周圍施以倒角。薄片被固定在台座面的狀態下，台座以 中央的旋轉軸作爲支點而如第4C圖般地廻旋。透過此，薄 片可被折彎，截至被賦予折痕爲止薄片被吸附固定在台 φ 座。在以上的此例中，薄片的保持與折彎是同樣在台座上 進行。因此，光是提高薄片之座落位置之反覆精度，可使 折彎位置之反覆變動縮小。 此外，把薄片固定於台座的手段，除了像此例之真空 吸附以外亦有各種方法可被考慮。尤其像在薄片上形成有 機能部時，若是爲不賦予薄片大的變形，不使機能部受到 障礙的範圍內時’可適用各種手段。例如，在台座面上設 置厚度極薄的吸盤，或亦可考慮在堤等之上設置機械方式 之從上部夾住的機構。再者，在薄片上若具有介電性時， -14- 200831272 亦可將台座面作成陶瓷製的靜電夾頭方式。 在此例中，薄片接觸的台座面，從正面看乃如圖所示 係賦予朝向右下方變低般的傾斜。此外，如前所述，此傾 斜面可爲平面狀或曲面狀。又在右側的固定台座亦賦予傾 斜，左側之廻旋部的傾斜可比此還大.，但在此情況，兩者 的斜面係以能流暢的相連者爲宜。再者，薄片的形態，例 如亦可朝向圖的進深方向賦予傾斜，亦可對左右方向與進 深方向雙方賦予傾斜。 ^ 此外，傾斜之面的傾斜角以5至3 0度爲宜，1 5度以 下更理想。此外在曲面之情況的傾斜角，係在台座的最高 點拉的切線與水平線所形成的角度。例如，第4C圖中係左 側之高部的切線與固定台座面所形成的角度。透過此，可 沿著斜面使薄片滑動，將其前端抵住堤23而可容易定位。 使用傾斜角爲0度的台座時，事先在與薄片的兩端之間空 著些許餘隙而設置堤，或若不把薄片端的單邊固定時，薄 片會朝與折彎軸正交的方向偏位。例如，在第4 C圖中則會 _ 向左右方向偏位。然而，本發明之裝置的台座面，因爲向 左右方向傾斜，所以薄片端自然抵接於堤而可定位。因此 不需要像上述傾斜角爲0之台座那樣需要特別的定位手 段。此外傾斜角小於5度則因與壁面之摩擦而不易滑動， 超過30度時由於觸及堤而使薄片容易發生撓曲，並使定位 困難。在此狀態下立即從台座的中央孔29透過真空吸引可 使折彎部確實固定於規定位置。在第4圖的例子因爲成爲 些許向下方凹陷之流暢的曲面，所以平坦的薄片，在座落 -15- 200831272 之後隨即被把持之拉緊狀態下會在折彎部附近呈些許浮起 的狀態。因此，即使在薄片下面有些許的凸出部或起伏， 在透過其進行吸附之際成爲變形亦不會影響到上面。此 外，與此曲面凹陷部之間隙的最大値，亦依薄片下面之起 伏狀態而定，通常以在薄片厚度的0.7至1.3倍左右的範圍 爲宜。偏離此範圍則容易發生彎曲位置的偏差，容易因該 偏差而造成損傷。此外以虛線表示之部分，係與前述之吸 引孔相連的溝槽，此亦有同樣的效果。 ^ 以上從運送一直到折彎爲止的一連串加工，係以長方 形即如第2A圖所示般以每薄片單位執行的情況爲例子作 了敘述。然而，亦有像第2B圖及第2C圖的情況以複數個 薄片單位相連者爲對象的情況，在如此的情況下，一面減 少對機能部的影響一面也充分考慮爲了完成高精度之折 彎的時間或製造能力，也有需要依照個別的情況而進行裝 置的設計。因此也包含上下方向而與三維的薄片運送手段 0 (—例爲從圖面近側到深處、從圖面的上方運送到下面） 組合，同時可考慮與其相稱之廻旋台座的構造或其佈置。 此外，不論何種情況本發明之折彎裝置的基本構成並無改 變。 在將長條材料或複數個薄片單位相連之物品彎曲時， 係以無論是第2B圖或第2C圖之任何配置，都能使在割斷 部分折彎加工時之應力止住的方式，於薄片形成較長或較 廣的貫通孔等，或與其同時，預先在薄片賦予蛇腹狀的折 痕部爲宜。又在彎曲加工時把薄片的割斷部，例如以夾子 -16- 200831272 機構等進行物理上的拘束者爲宜。其原因在於，在恢復力 強的薄片之情況，彎曲的應力傳遞給相鄰之彎曲前的薄 片，有對機能部等施加衝擊之虞。 在作了以上之後，例如有，(1)如第2C圖的情況，從 使傾斜之台座的上部，將此長條薄片朝長度方向連續地送 進，使把持立掛在台座之直立的內壁之方式的手段。在此 種情況，薄片係剛送進之後立即以補助手段一面保持與壁 密接一面從橫向以廻旋台抑制而折彎。同樣地例如亦有， (2)於長度方向把數十片份之單位薄片相連的長方形從第！ 圖之裝置近側的面朝向深處送進，一面與此單位薄片數相 稱並排之複數個廻旋台保持且一舉彎曲的手段。如此各種 設備設計。此外在（1 )、（2)之任何情況，也可考慮在折彎的 同時利用割斷部割斷。當然，即使是此種複數個薄片單位 相連之薄片的情況，本發明之折彎裝置的基本構成也並無 改變。 在以第1圖之設備佈置作爲基本之以上的例子中，被 折彎之薄片1，係以把持部3 2把持送到第1圖之左側的折 疊裝置4。在此運送中能使由於恢復致折彎角度不會變大 的方式，與折彎前的運送一樣，亦有一方面使長度方向施 加適度的拉緊狀態下被把持移送的情況。又若設備佈置或 折彎手段改變的話，在此運送手段也可考慮分別與其情況 相稱者。此外如前所述，在折彎前、折彎中及折疊過程， 適當地設置用以執行容易帶電之薄片及台座之表面的除電 處理或帶電防止處理的機構。其後在本事例中，則藉由通 200831272 過如第1圖般設有適度間隔之屬折疊手段的輥子而被折 疊，再作裝袋等的處理。此外考慮薄片的生產性或實用性， 亦有以多段式輥子作階段折疊的情況。接合亦有並非利用 黏著部而係以壓接或熱壓接等方式，並於折疊後以各種手 段執行的情況。以下透過實施例介紹本發明之一例，但本 發明之折彎裝置，包含有亦考慮到按本發明之基本構成而 在薄片上具有機能部的情況之機能的維持及折疊之方便性 等各種實施形態，但並不限定於此。 ®實施例1 準備如第2A圖所示之長方形狀其寬度爲8〇mm、厚度 爲0.2mm之紙、聚對苯二甲酸乙二醇酯（以下簡稱pET) 及純鋁（A1)所形成之長條薄片。將該等原材料薄片從輥子 送到第1成型機，首先沿著其長度方向在其寬度方向的中 央賦予折彎用的縫紉針孔。接著送到第2成型機，在與長 度方向成直角的方向以160mm的間隔割斷成長方形。縫紉 φ 針孔均爲虛線狀，在穿孔的周邊緣具有從面突出大致 20 /z

Description of the Invention: [Technical Field] The present invention relates to a sheet bending device in which a bending promotion portion is provided in advance. [Prior Art] In the production of boxes, bags, thin data boxes, etc., such as paper or resin, bending of a sheet to be a raw material is performed. In that case, unless it is a special item; it is usually carried out in an automated production line. Therefore, there is a need to supplement the equipment which can ensure the accuracy of the repetitive position of the bent portion and reduce the variation of the bending angle after the bending to make the folding easier. Further, in order to facilitate the bending of the sheet itself at a predetermined position, the sheet itself is provided with a portion for facilitating the bending process (hereinafter referred to as a bending promoting portion). For example, a line-shaped recess or a portion (hereinafter referred to as a ruled line) is provided along the bending line of the sheet. In the case of such a sheet, (1) a functional layer (hereinafter also referred to as a functional portion) is formed by means of printing such as an electronic circuit or a decorative painting, and (2) an image cassette or the like is formed only by a sheet. In particular, in the former case, it is important that the functional portion formed on the sheet does not adversely affect and is effectively utilized and efficiently bent. In the conventional bending means, the sheet is divided into a predetermined shape unit and carried out one by one, and the bundle is supplied in a plurality of sheets or a long sheet without being divided. Examples of the former include a web method using a chopper method, a model plate that abuts against a triangle, and a rotary table method. There are various means depending on the difficulty of bending. For example, a composite of a resin and a metal laminate which is a material which is difficult to bend is formed by being mounted on a nip roller and molded by a mold. 200831272 There are several methods for bending in high precision in the patent literature. For example, Japanese Laid-Open Patent Publication No. Hei 7-86307 (Patent Document 1) discloses an example in which a long sheet is supplied and formed by bending a model. This example is a means for pressing the meandering of the sheet without setting the meandering mechanism to ensure the repeating accuracy of the bending position. In particular, since the sheet having a small width has a large resistance to the adhesion between the original material and the mold wall on both sides of the bent portion, an unevenness in the bending resistance is generated on both sides thereof, and it is easy to be biased toward the side where the resistance is large. Therefore, the crease is correctly bent at the tip end of the V-shaped plate of the model plate by a plurality of roller guides. Japanese Laid-Open Patent Publication No. Hei No. 7-3309 (Patent Document 2) discloses a case of bending of a paper or resin case having a strong restoring force after bending. While pressing the curved portion with an opening band or a roller, the recovery of the bending is avoided, and the sheet is sandwiched by the tape to move horizontally. In this state, a sheet adhesive layer is applied, and a sheet is slowly pressed to bend and fold the sheet by a roller and a twist belt. An example of a device that simplifies the collection of such a series of actions. Japanese Patent Publication No. Hei 9-26797 (Patent Document 3) discloses a method in which a sufficient crease cannot be applied to a sheet such as paper, synthetic paper or metal foil by a nip roller. The sheet is half-folded by the guide sheet and the guide roller, and heated in advance (80 to 120 ° C) in the vicinity of the crease, and the crease is imparted by pressing the pressure along the crease by the roller. In addition, it is necessary to provide a bending promotion unit (such as a grid line) for a raw material that is difficult to impart a crease. For example, a groove having a V-shaped cross section or a trapezoidal shape, a perforation type in which a sewing needle hole shape or a long hole is intermittently formed, an unevenness imparted to the bottom portion of the groove, and a parallel groove provided to the groove are used. Most of them are arranged in a straight line. Japanese Laid-Open Patent Publication No. 2004-243716 (Patent Document 4) discloses a resin sheet having a wavy line in the thickness direction and having a bending line of a certain depth of 200831272 degrees in the thickness direction. Accordingly, it becomes easier to bend. It is easy to occur on the harder resin, and the damage caused by the bending is hard to occur.

[Problem to be Solved by the Invention] Japanese Laid-Open Patent Publication No. Hei 7-108307 (Patent Document Document) is a method in which a sheet having a relatively narrow width is folded into two halves, and a one-way route is determined. Such a means is a sheet having a weak applicability (hereinafter also referred to simply as a restoring force). A sheet formed of a material having a strong resilience is difficult to apply. On the other hand, Japanese Patent Publication No. 7-330206 (Patent Document 2) The method disclosed in Japanese Laid-Open Patent Publication No. (Patent Document 3) is applicable to the recovery material itself, but the former overlaps with the roller in sliding contact with the roller, while the latter is directly heated to the sheet only by the bent portion. The possibility of damaging the function of the sheet forming the functional layer is high. The same is true of the method of the present invention. The object of the present invention is to provide a bending device which can be used even with a strong sheet. The accuracy of the repetitive position of the bent portion is reduced, and the variation of the bending angle after the bending is reduced to make the folding easy. The curve is made to the square line state, and the t-report is reported to the newspaper. The invention is a bending device, which is a material for the patent and is twisted and twisted by the patent 267 971. Therefore, it is a resilience and a patent for the patent document. A flat sheet provided with a bending promoting portion is bent along the bending promoting portion, and has a conveying means for holding the sheet and transferring it to a pedestal having a slewing portion, and the bending promoting portion is along the pedestal a holding means for positioning the sheet at the position of the slewing portion of the slewing portion, and a bending means for bending the sheet by twisting the slewing portion of the pedestal, the holding means arranging the sheet before bending obliquely with the bending promoting portion A sheet bending device in an orthogonal direction. Further, in the present invention, the inclined arrangement is performed by forming a slope on the pedestal, and in particular, the inclined surface has an inclination angle of 5 to 30 degrees, and further includes a curved surface having a curved surface. [Effect of the Invention] According to the apparatus of the present invention, even in the case of a sheet having a strong restoring force, the accuracy of the repetitive position of the bent portion can be easily ensured, and the positional variation between the sheets after the bending can be reduced. Further, the variation of the bending angle after the bending is reduced, and the restoring force is also weakened. Therefore, the folding and the joining of the time are also made easy. Further, the sheet is not bent to a large degree of deformation and distortion, and can be bent into a preferred embodiment of the invention. An example of the sheet bending apparatus of the present invention will be described below using the drawings. Fig. 2A shows the planar shape of the rectangular sheet 1 which is folded in half in the center in this example. The sheet has a rectangular shape, and a ruled line 11 (a portion shown by a broken line in the figure) having an island-shaped hole which is a bending promotion portion is formed at a central portion in the longitudinal direction. The side of one of the ruled lines (on the right side of 200831272 in the figure) is formed, and the functional portion formed by the functional film 1 2 is grasped by grasping the left end toward the right side of the functional portion. In this example, for simplification of description, the sheet is folded into two halves, and the sheet supplied to the apparatus of the present invention is as shown in Fig. 2C, and the respective sheet units described in Fig. 2 are connected in the longitudinal direction or the width direction. article. It can also be 12 people. Further, for example, it may include a functional portion and may be flanked on the sheet surface. The form of the bend promoting portion may be linear, and the pattern may have various forms. The raw material of the sheet, the metal foil, and the composite material or composite material of the sheet may be soft. In addition, when the material of the sheet is based on a material having a weak restoring force, even if the bending promoting portion is not placed on the turret, the bent sheet may be easily bent to provide a bending promoting portion. An example in which the entire configuration of the apparatus of the present invention is made easier to bend is used. The portion drawn by the dotted line on the right side is the drive shaft 3 3 of the transport means 3 used in the previous process, and 31 is the sheet 1 transported in the direction of the side of the sheet, which is defined in the figure from the grip portion 3 1 The twisting pedestal 2 of the bending means enters the bending process toward the arrow surface. Further, at the stage of being conveyed, the end portion of the sheet is held by another grip portion (not shown), and is moved in a tension state of a substantially constant degree. In addition, it is moved to the pedestal in the state of the full length or a plurality of points of the sheet. The sheet is folded by the θ ruled line and may be a small hole or a curved or curved shape in the inorganic energy portion, which is a resin, and the material is supported as long as it has a flexible bend. However, thin automation. In the figure, it is said that the sheet is conveyed to the holding portion. The sheet which is separated from the right and which is hovering in the other direction and held in the proper direction, 200831272 is held flat, and the deformation of the sheet during movement can be suppressed. Therefore, the functional portion such as the film deposited on the sheet surface or the thick film to be printed is not damaged. Further, the drive shaft is moved along the rail 35. The grip portion is horizontally rotatable about the drive shaft and is movable up and down along the drive shaft in the vertical direction. The turret pedestal 2 is in a state in which the slewing portion is opened around the sway shaft 27 as indicated by a broken line before the sheet is seated and fixed. The sheet is suspended from the grip portion 31 and the other grip portion (not shown), and is seated across the fixed pedestal 21 and the turret pedestal 22. Further, in this example, the slewing pedestal is inclined so as to be inclined toward the left side, and the sheet is hit by the bank 2 at the right end of the fixed pedestal to be positioned. Further, a bank 24 for positioning is also provided at the left end of the fixed pedestal. There are various ways to position the sheet in addition to the bank. For example, a plurality of positioning holes may be formed in the end portion of the sheet to fit the projections having the same shape as the pedestal. Further, in the case where continuous supply of the sheet requires high-speed positioning, the pedestal can be aligned with the sheet by optical means. The surface of the pedestal carrying the sheet is preferably formed of a porous ceramic material, a porous carbon material, and a ceramic electrostatic chuck material to form a desired smooth seating surface. According to this, damage of the sheet at the time of adsorption can be prevented. The thin film is held in a tensioned state in which the tilting direction of the pedestal surface is orthogonal to the bending promoting portion. Then, the sheet is closely fixed to the suction mechanism (not shown) provided on the pedestal, and the turret is rotated in the direction of the arrow as shown in the figure to cause the sheet 1 to be bent. The sheet which has been bent to a predetermined angle is held by the grip portion 32 of the drive shaft 34 as shown, and is folded by the next folding -10- 200831272 means 4 (roller mode in this figure). A sheet of an insulating material tends to accumulate static electricity on its surface. When the surface of the bent pedestal is an insulating material, static electricity is easily accumulated on the surface of the pedestal. In such a case, after the charged sheet is bent, it is recovered by the static electricity together with the pedestal, which may cause an obstacle in the next folding. A sheet having a large elasticity tends to be particularly strong. Furthermore, when temporarily folded and placed together after bending, it is also difficult to separate due to static electricity between the sheets. Thus, when the surface of the sheet or the surface on which it is in contact is charged, the sheets are easily attached to each other or restored to the state before the bending due to static electricity. Therefore, there is a case where the separation between the sheets or the bending state is maintained. In order to prevent such troubles, it is preferable to apply a temporary static elimination means to the sheet surface or its contact surface before bending, or to apply a means for permanently preventing charging. However, when the organic energy portion is provided on the sheet, it is necessary to take a preventive means that does not adversely affect its function. In the case of the charge-removing treatment, for example, a method of blowing ionized air in accordance with a charging condition, a method of spraying a moisture-absorbing component such as polyethylene glycol, and a liquid such as potassium hydroxide which promotes ionization, and a method of containing A method of spraying a charge inhibitor of a surfactant onto a target surface. The hygroscopic component prevents re-charging based on the hydrophilicity of the hygroscopic action. The permanent antistatic charging prevention treatment is, for example, a method of evaporating a conductor such as metal or carbon onto a target surface. This improves the conductivity of the surface and prevents re-charging. If the surface of one of the sheets before the bending and the pedestal surface that is in contact therewith are treated as described above, the object can be achieved. Further, in this example, the sheet is horizontally moved, but other examples of the apparatus of the present invention can be freely moved in the vertical direction. The orientation of the pedestal is also .200831272 can also be changed freely. For example, a means for sliding the sheet from the upper portion along the inner wall thereof, positioning against the lower bank or the like, and immediately adhering to the inner wall by the holding means is also employed. Such a three-dimensional arrangement depends on the shape of the sheet or the shape of the functional portion, but is more suitable for paper or the like, particularly a sheet-thickness. Fig. 3 is a view showing an example of a turret of the apparatus of the present invention for bending a rectangular sheet of this example. In addition, the sheet is fed from the lower right of Fig. 3 in the direction of the arrow. In the figure, 2 to 27 are the fixed pedestal on the front side in the transport direction, the turret seat on the deep side in the transport direction, the dyke mounted on the fixed pedestal, the dyke mounted on the turret, the fixed pedestal, and the turret Face and axis of rotation. In the example of the sheet in the form of Fig. 2A, the ruled line formed in the crease of the bending promotion portion is seated in a state of being tensioned in conformity with the axis of the center of the pedestal. Then, the grip portion 3 is held by the grip portion of the other end while the end of the one side of the sheet is gripped. Further, a sheet (not shown) is placed in a predetermined position in a state of being tensioned over the entire surface by a holding means such as vacuum suction provided on the pedestal. Immediately thereafter, the sheet is released from the grip portion, and the grip portion is moved to the right in the first drawing and retracted to a position away from the pedestal. Further, in the case where the sheet having no bending promoting portion is closely held to the pedestal, a means for removing the deviation of the actual bending position is required. For example, after the end portion of the sheet is positioned and held in close contact, the wire to which the tensile force is applied is brought into contact with the bending line along the bending line and held down. In that case, the entire length of the covered wire is formed into a downwardly convex elliptical shape, and the convex portion may be in a state of being in contact with the bent portion. For another example, -12-200831272, the weakened sheet after bending can also be positioned to remain in close contact with each other and then vacuum-clamped along the turret axis of the pedestal for forced adsorption. Further, for example, if the functional portion is not affected, a linear heater may be used to appropriately indirectly heat or use a central suction hole to linearly contact the refrigerant or the moisture to promote bending. Then, as shown in Fig. 1, the pedestal slowly whirls in the direction of the arrow. Through this, the sheet of the pedestal surface is bent following the same trajectory as that of the pedestal pedestal 22. Further, the inner angle after the sheet is bent is preferably less than 15 degrees, more preferably less than 10 degrees, in consideration of recovery in the transportation between the next folding processes. Fig. 4 is a view showing an example of a bending mechanism of the sheet of the present invention in a bending stage. 1 is a rectangular sheet as described above, and is carried on the turret pedestal 2 in a state before bending. This figure shows the A-A of the pedestal in Fig. 3. The section is drawn with the width direction of the sheet as the front side, and the depth direction is the length direction. Although not shown, a grid line for facilitating bending is formed in the center of the sheet. The pedestal 2 is provided with a yoke 23 (not shown) that is used to align the pedestals at the center portion with the dams 23 and 24' that are positioned to abut the ends of the lamella. The pedestal is bent by bending the sheet as shown in Fig. 4C with the axis as a fulcrum. The pedestal surface to which the sheet is in contact is inclined as shown from the front as it goes downward to the lower right. This bevel can also be a flat face. In the example of this figure, the turret 22 on the left side of the shaft forms a slope of a concave curved surface. Further, the inclination is not shown, and it can be inclined at an optimum angle by the elevating mechanism built in the turret. The broken line portion 2 8 is a gap (hereinafter also referred to as a groove) formed in the surface direction of the pedestal and a vacuum suction hole connected thereto. In addition, the depth of the groove in the figure is drawn at a height of 200831272 degrees, as long as it is about 0.3 to 1 times the thickness of the sheet. Further, the cross section is drawn in a rectangular shape. However, in order to reduce the contact deformation with the flat sheet, a chamfer may be applied to the corner to form a smooth cross section. The depth of the groove is set to this range because when it is less than .3 times the thickness of the sheet, the suction resistance is increased, especially when the thickness of the sheet is insufficient, and if it is more than 1 time, the sheet is thin. It is easy to deform when adsorbed. Therefore, the sheet is easily deformed out of this range, and is easily damaged to the functional portion. 29 is the central vacuum suction hole. The path including the suction hole 28 provided at the bottom of the groove 28 吸 is sucked downward as indicated by the arrow of Fig. 4B, so that the sheet is attracted to the pedestal surface. In this case, the surface of the pedestal is made porous and can be attracted through the vent hole. Further, when the ruled line portion has a projection, chamfering may be applied around the upper end of the suction hole in order to avoid the bottom end of the projection. In the state in which the sheet is fixed to the pedestal surface, the pedestal is circulated as shown in Fig. 4C with the central rotating shaft as a fulcrum. Through this, the sheet can be bent, and the sheet is adsorbed and fixed to the table φ seat until the crease is given. In the above example, the holding and bending of the sheet are performed on the pedestal as well. Therefore, the light is used to improve the repeating accuracy of the seating position of the sheet, and the variation of the bending position can be reduced. Further, in addition to the vacuum adsorption of this example, various means can be considered in addition to the means for fixing the sheet to the pedestal. In particular, when a functional portion is formed on a sheet, various means can be applied if the sheet is not deformed greatly and the functional portion is not subjected to the obstacle. For example, a suction cup having a very small thickness may be provided on the pedestal surface, or a mechanically sandwiched mechanism may be provided on the dyke or the like. Furthermore, if the dielectric property is present on the sheet, the pedestal surface can also be made into a ceramic electrostatic chuck method from -14 to 200831272. In this example, the pedestal surface in contact with the sheet is inclined as shown in the front view as shown in the lower side. Further, as described above, the inclined surface may be planar or curved. Also, the fixed pedestal on the right side is also inclined, and the tilt of the left side of the hem is larger than this. However, in this case, the slope of the two is preferably a smooth connection. Further, in the form of the sheet, for example, it is possible to impart inclination to the depth direction of the drawing, and to impart inclination to both the left and right direction and the depth direction. ^ In addition, the inclined angle of the inclined surface is preferably 5 to 30 degrees, and more preferably 15 degrees or less. In addition, the inclination angle in the case of the curved surface is the angle formed by the tangent and the horizontal line drawn at the highest point of the pedestal. For example, in Fig. 4C, the angle formed by the tangent to the upper portion of the left side and the fixed seating surface. Through this, the sheet can be slid along the slope, and the front end thereof can be positioned against the bank 23 to be easily positioned. When a pedestal with a tilt angle of 0 degrees is used, a levee is provided in advance with a slight gap between the ends of the sheet, or if the unilateral end of the sheet is not fixed, the sheet is oriented in a direction orthogonal to the bending axis. Offset. For example, in Figure 4C, _ is offset in the left and right direction. However, since the pedestal surface of the apparatus of the present invention is inclined in the left-right direction, the sheet end naturally abuts against the bank and can be positioned. Therefore, it is not necessary to require a special positioning means like the above-described pedestal with a tilt angle of zero. Further, when the inclination angle is less than 5 degrees, it is less likely to slide due to friction with the wall surface, and when it exceeds 30 degrees, the sheet is likely to be deflected due to the contact with the bank, and positioning is difficult. In this state, the bent portion is surely fixed to a predetermined position by vacuum suction from the center hole 29 of the pedestal. In the example of Fig. 4, since it is a smooth curved surface which is recessed downward, the flat sheet is slightly raised in the vicinity of the bent portion when it is gripped and pulled immediately after the seat is lowered -15-200831272. Therefore, even if there are some protrusions or undulations under the sheet, the deformation does not affect the upper surface when it is adsorbed through it. Further, the maximum 値 of the gap with the concave portion of the curved surface depends on the undulating state below the sheet, and is usually in the range of about 0.7 to 1.3 times the thickness of the sheet. If it deviates from this range, the deviation of the bending position is likely to occur, and it is easy to cause damage due to the deviation. Further, the portion indicated by a broken line is a groove connected to the aforementioned suction hole, which has the same effect. ^ The above-described series of processing from the conveyance until the bending is described as an example in which the rectangular shape is executed in units per sheet as shown in Fig. 2A. However, there are cases in which a plurality of sheet units are connected as in the case of FIG. 2B and FIG. 2C. In such a case, the effect of reducing the influence on the functional portion is also considered in order to complete the high-precision bending. The time or manufacturing ability, there is also a need to design the device according to individual circumstances. Therefore, the vertical direction is also included in combination with the three-dimensional sheet conveying means 0 (for example, from the near side to the deep side of the drawing, from the upper side to the lower side of the drawing surface), and the configuration of the pedestal pedestal or the arrangement thereof can be considered. . Further, the basic configuration of the bending device of the present invention does not change in any case. When the article in which the long material or the plurality of sheet units are connected is bent, the stress at the time of the bending of the cut portion can be stopped in any of the configurations of the 2B or 2C. It is preferable to form a long or wide through hole or the like, or at the same time, to provide a crease portion of the bellows in advance. Further, it is preferable to physically cut the cut portion of the sheet during the bending process, for example, by a clip-16-200831272 mechanism. The reason for this is that in the case of a sheet having a strong restoring force, the bending stress is transmitted to the adjacent sheet before the bending, and there is a possibility that an impact is applied to the functional portion or the like. After the above, for example, (1) as in the case of FIG. 2C, the long sheet is continuously fed in the longitudinal direction from the upper portion of the inclined pedestal, so that the grip is hung upright in the pedestal. The means of the wall. In this case, immediately after the sheet is fed, it is bent while being held in contact with the wall by the auxiliary means while being restrained by the rotator from the lateral direction. Similarly, for example, there are (2) rectangles in which tens of pieces of unit sheets are connected in the length direction from the first! The surface on the near side of the apparatus of the figure is fed toward the depth, and a plurality of squashing tables which are arranged side by side with the number of unit sheets are held and bent. So various equipment designs. In addition, in any of (1) and (2), it is also conceivable to cut with a cut portion while bending. Of course, even in the case of such a plurality of sheets in which a plurality of sheets are connected, the basic constitution of the bending apparatus of the present invention is not changed. In the above-described example in which the apparatus arrangement of Fig. 1 is substantially the above, the folded sheet 1 is gripped by the grip portion 32 to the folding device 4 on the left side of Fig. 1 . In this case, the folding angle can be prevented from increasing due to the recovery, and as in the case of the pre-bending conveyance, the longitudinal direction can be gripped and transferred in an appropriate tension state. If the arrangement of the equipment or the means of bending is changed, the means of transport may also be considered to be commensurate with the situation. Further, as described above, the mechanism for performing the static elimination treatment or the charging prevention treatment of the surface of the easily charged sheet and the pedestal is appropriately set before the bending, during the folding, and during the folding process. Then, in the present example, it is folded by a roller which is provided with a moderately spaced folding means as in Fig. 1, and is processed by bagging or the like. In addition, considering the productivity or practicability of the sheet, there are cases in which the multi-stage roller is folded in stages. The joining may also be carried out by various means, such as crimping or thermocompression bonding, without using the adhesive portion. In the following, an example of the present invention will be described by way of examples. However, the bending apparatus of the present invention includes various implementations such as the maintenance and folding convenience of the function in the case where the functional portion is provided on the sheet in consideration of the basic configuration of the present invention. Form, but not limited to this. ®Example 1 Prepare a rectangular paper having a width of 8 mm and a thickness of 0.2 mm as shown in Fig. 2A, polyethylene terephthalate (hereinafter referred to as pET) and pure aluminum (A1). Long strips. These raw material sheets are sent from the rolls to the first molding machine, and first, sewing needle holes for bending are provided in the center in the width direction along the longitudinal direction thereof. Then, it was sent to a second molding machine, and was cut into a rectangular shape at an interval of 160 mm in a direction perpendicular to the longitudinal direction. The sewing φ pinholes are all in the form of a broken line, and have a tapered projection at a peripheral edge of the perforation that protrudes from the surface by a height of approximately 20 / z m. Further, a sheet having the same width and the same thickness as that of the above-mentioned material was prepared, and after the sewing needle hole was formed to accommodate the thicknesses, it was cut into a rectangular shape having a length of 160 mm in the same manner as described above. Further, the peripheral edge of the sewing pinhole has a projection having a height which is about 0.3 times the thickness. Each of the sheets produced in the above-described order was adsorbed and fixed to a flat substrate formed of a glass fiber reinforced epoxy resin in a manner that the linear protrusion of the sewing needle holes was prevented. Next, bend the center of the surface on the surface side of the rectangular sheet -18-

By applying the medicine for the trauma (the sheet material symbol a), the pattern of the paper sheet-soluble paint (the sheet material symbol b), and the oil paint of the A1 (the sheet material symbol c) to the predetermined printing machine, respectively, Dry and fix. Although these are lightly fixed by applying a protective agent or the like, they are exposed to the local temperature and are deteriorated by the exposure of the sheet. In addition, a sheet of PET (sheet material symbol d) of the functional portion is also provided. For the sheet, 50 sheets of the sheet for bending the material were prepared under the respective conditions shown in Table 1. In addition, the data of the thin sheet in the first table is the arithmetic average 1 of 10 sheets. The bending test is to move the sheets in parallel to the bending pedestal in a state of being tensioned by the first drawing, and in accordance with In addition, as shown in the column of "The form of the inclined surface" in the first table, it is used as a flat person and a curved surface. The state in which the first portion is grasped is as shown in Fig. 4, and the length of the sheet is touched by the bank 24 having the inclined turret 22 of the inclined surface. A tensioned state in which the sheet is substantially in full contact with the fixed pedestal and seated. Immediately from the suction hole 29 in the center of the figure, the bent portion of the sheet to which the ruled line is attached is completely adsorbed along the land of the pedestal. Then, suction is performed from the fixed pedestal and the turret double suction hole 28, and the bending line of the sheet is held in close contact with the pedestal surface. Further, the suction hole 28 is slidable up and down in the shallow groove portion, and the pattern net for using the water sheet which can change the PET sheet is dry and curved, and is prepared to be unused. test. "Each test: quality of the film" The transport mechanism is loaded in the following order. The pedestal surface is equipped with the front sheet in the holding direction at the pedestal and the whirlpool starts the vacuum suction center line automatically: and is almost completely under the sheet. Use the groove -19- 200831272 The depth of the groove. Through this, a bending test material which changes the depth of the groove is also produced. Then, the pedestal is whirl-turned so that the test materials are bent until the inner corner of the sheet in the width direction is about 5 degrees, and after being held for 1 sec., the vacuum suction is stopped and the dome is opened while the sheet is floating. Seat, remove the sheet from the pedestal. The inner corner of the sheet at the time (the "initial bending angle" of the first table) is confirmed by a projector. Further, since the test materials 1 1 and 12 did not form the functional portion, the linear heater was applied to the bending line from the upper portion before the turret was rotated, and the surface temperature was raised to 100 ° C before the folding was started. Further, since the test materials did not form the functional portion, the ends of the width of the sheet were overlapped and brought into contact (up to the inner angle of the bend of 0 degrees), and held for 10 seconds in this state. After that, all the test materials, as described in the column "Quality of the sheet" in the first table, were checked for the presence or absence of damage to the functional portion, the presence or absence of the change in the bending position, and the initial bending angle in the state where the bending was released. The degree of recovery (recovery rate). In addition, regarding the degree of damage, the presence or absence of I damage was confirmed by a naked eye through a microscope of 100 times and visual observation by a naked eye. The deviation between the initial bending angle and the bending position is confirmed by the projector. In addition to the sheet of A1 and the sheet of A1 which were hardly confirmed beforehand, the sheet was placed in a drying room at room temperature for 72 hours, and the bending was confirmed in the same manner immediately afterwards.

One of the 1000 sheets was bent in the same manner as the above-described order, and the remaining one sheet was blown to the surface by an electrostatic eliminator containing ion-containing air. Specifically, the static elimination treatment of blowing the antistatic agent S-250 manufactured by Shishid Seiki Electric Co., Ltd. to the surface on which the functional portion is not formed is added before the bending. As a result of evaluating the quality of the sheet as described above, there is almost no difference in the degree of deviation between the former and the damage state or the bending position shortly after the bending. However, after confirming the degree of recovery after one hour of bending, the recovery of all the test materials of the former exceeded 20%, ranging from 2 5 to 40% (equivalent to the evaluation of △), but the recovery of the latter was all at 5 Within the range of 2 to 5% (equivalent to the evaluation of ◎). In addition to PET, the same tendency was obtained after comparison of various resin sheets formed of polypropylene, fluororesin, and enamel resin of the same thickness and paper of the same material as test material No. 8 and having a thickness of 2 mm. data of. From the above results, the following conclusions can be made. (1) In the case of a PET sheet, when the thickness is increased, even in the same bending condition, the bending angle becomes larger depending on the initial elastic recovery, and the deviation and recovery in the bent portion become large, but There is no damage to the functional department. (2) When the pedestal is not a bevel, the bending position is deviated and the recovery after the bending becomes larger than when the bevel is used as the pedestal in the present invention. By the way, the test material 1 7 to 2 i with the inclined surface as the pedestal is restored from the original 12 degrees (maximum of 2 1 ) to 13 degrees, and the test material of the comparative example with the horizontal plane as the pedestal is restored. To 16 degrees. (3) In addition, the inclination angle of the slope is preferably 30 degrees or less. The deviation of the position when it exceeds 3 degrees • 23- 200831272 will become larger. (4) In the case of a curved pedestal, the gap between the curved surface and the contact surface of the sheet is suitably between 0. 3 and 1 times the thickness of the sheet. For example, if the thickness is 1 mm thick, the gap is smaller than this range, and there is a possibility of positional deviation. On the other hand, when the thickness is 0 · 5 m m, the gap is larger than this range, and there is a possibility that an obstacle occurs in the functional part. Further, (5) applying a static elimination treatment to the sheet before the bending, the static electricity after the sheet surface is removed in advance, and the recovery after the bending can be suppressed to be small. Example 2 The paper (sheet material symbol b) and PET (sheet material symbol a) which were the same as those of the first embodiment were prepared, and the width and the length were the same, and the thickness was the rectangular sheet described in the "sheet" column of the second table. And the long raw material sheets which are connected in the form of FIG. 2B, and the raw material sheets are preliminarily mounted on the molding machine in the same manner as in the first embodiment, and the cutting line is formed into a lattice having a length of 2 mm and a spacing of 1 mm which enables simple cutting. In the line, the bending promotion unit applies a bending line of a ruled line having the same pattern as that of the second drawing in the sheet unit. The long strips were fed into the bending pedestal as they were, for bending tests. The long sheet is conveyed at a constant speed while the tension is gently applied from the supply side roller by the tightening roller, and the thick film (function portion) of the medicated medicine is printed in the same portion of the sheet of the second drawing. Then, the tension was applied to the sheet by the tightening roller, and the functional portion was dried and fixed for 15 seconds. Then, the coating was inclined from the horizontal plane by substantially the same configuration as the third drawing in which the seat surface was coated with the resin. The degree of the twisting pedestal performs a continuous bending process. Further, in the test, as described in the second table, the same evaluation as in the first embodiment was performed by changing the inclination angle formed with the inner wall surface of the pedestal (only the inclination angle is shown in the second table). -24- .200831272 In order to compensate for the time lag between the processing of the substrate and the bending process at the pedestal, the cut portion is appropriately folded and stored in a state of being bent before being sent to the pedestal. Then, the portion from the front end is intermittently fed from the upper portion of the pedestal to the inside of the pedestal. The sheet was intermittently fed to the pedestal at intervals of 160 mm in a rectangular cut length, and was held close to the pedestal by a suction mechanism built in the pedestal, and was bent by the rotation of the operation pedestal. Then, it is cut into a predetermined rectangular shape by a cutter under the pedestal and is slid down from the inclined belt to be recovered. Thereafter, the bag is folded in a folding device (not shown). The above results are shown in Table 2. -25- 200831272
