本發明之細微構造轉印膜之製造裝置，係至少具有 :無端環帶狀之模具，於表面形成有細微構造；加壓機 構，其至少具有用以加熱該模具之加熱輥、與加熱輥平 打配置且表面覆有彈性體之軋輥、及使用該兩輥之挾壓 手段；冷卻輥，其用以冷卻該模具；剝離機構，其用以 剝離密接於模具上之膜；及運送機構，其使該加熱輥及 該冷卻輥旋轉，用以運送該模具；該細微構造轉印臈之 製造裝置之特徵為： 於該加熱輥與該模具之接觸部的寬度方向兩端部， 以在寬度方向外側輥徑減小的方式，於該加熱輥之表面 有差，或者，该模具之寬度係比該乳棍加壓部的寬 度還寬。 第1圖顯示本發明之實施形態的一例，顯示自成型用 膜寬度方向觀察細微構造轉印膜之製造裝置丨的概略剖 視圖。 如第1圖所示，本發明之細微構造轉印膜之製造裝置 1 ’係具有該無端環帶狀之模具3、懸跨該模具3之加熱輥 4及冷卻輥5、與加熱輥4平行配置且對膜進行加壓成型之 軋輥6、及將成型後之膜自模具3剝離而作為剝離機構的 剝離輥7。又，加熱輥4與軋輥6係在將模具3及成型用膜2 -10- 201249668 積層之狀態下以兩輥夾入而予加壓，所以，至少任—方 之輥連接於按壓手段i 2而作為加壓機構所構成。另外， 作為以使懸跨於加熱輥4與冷卻輥5上之模具3旋轉的方 式進行運送用之運送機構，具有用以旋轉驅動加熱輥4 及/或冷卻輥5之驅動手段。另外，作為成型用膜2之運送 裝置，具有捲出輥8及捲取輥9，又，還可根據需要具備 一或複數個未圖示之導引報。 作為細微構造轉印膜製造裝置丨之動作’自捲出輥8 捲出之成型用膜2被供給於藉由加熱輥4所加熱之模具3 上，同時藉由軋輥6按壓於模具3之細微構造面3a，將與 模具3的表面形狀對應之形狀，即與模具3之細微構造為 相反圖案的細微構造轉印成型於膜2之成型面2a，然後， 在保持膜2與模具3密接之狀態下被運送，藉由冷卻輥5 進行冷卻，然後藉由剝離輥7自模具3上剝離，而捲取於 捲取輥9上。此動作係連續地進行。 使用第2及第3圖，針對本發明之特徵部分，藉由加 熱輥4及與加熱輥4構成一對之軋輥6對成型用膜2進行挾 壓之加壓成型部的裝置構成進行說明。 第2圖為顯示將成型用膜2之寬度作成比模具3的寬 度還寬’且於加熱輥4之兩端設置段差4&的情況之構造之 才具式圖。於加壓轉印製程中，當軋輥6直接接觸於被加熱 為π溫之模具3的細微構造面3 a時，會有產生軋棍6表面 之彈性層1 0的熱損傷及產生細微構造面3 a的傷痕之問題 ’因此’為了防止這些問題之發生，以將膜2之寬度作成 比模具3的寬度還寬較為適宜。於是，藉由設置段差“ -11- 201249668 ’將膜2之兩端部與加熱輥*分離，所以’不會有膜2與加 熱棍4局部黏著，可抑制膜2之蛇行而進行穩定之運送。 另外’第3圖為將模具3的寬度作成比成型用膜2之寬 度還寬’且將藉由軋輥6所加壓之區域的寬度作成比膜2 之寬度還窄的情況下之模式圖。與第2圖之構成相反，藉 由將膜2之寬度作成比軋輥6的加壓區域之寬度還寬，可 防止模具3的細微構造面3a與軋輥6直接接觸所引起的軋 概6之彈性層1 〇之熱損傷。於是，藉由將模具3之寬度作 成比膜2的寬度還寬，臈2全面被模具3所支撐，所以，可 防止膜2與加熱親4之局部性黏著，其結果，與第2圖之構 成相同，可抑制膜2之蛇行而進行穩定之運送。 於習知技術中’一般取軋輥6之加壓區域的寬度為比 模具3之寬度更寬的寬度’且將成型用膜2之寬度作成比 ' 之寬度還寬’藉此’可防止軋親6直接接觸於被加 ‘、、、為间皿之模具3的細微構造面3 a。然而，於此情況下， 本發明者等查明，於將模具3及加熱輥4加熱為高溫進行 送夺於比模具3更靠寬度方向外側的區域，加熱輥4 與膜2會發生局部黏著，致使膜2之運送張力在寬度方向 上變得不均等’從而有引起膜2之蛇行的情況。 本發明係針對成型用膜2、模具3、加熱輥4及軋輥6 以使加壓成型部上之各自的寬度成為所確定之大小關 ，藉此即使使模具3及加熱輥4形成高溫後連續地進 订轉印’膜2與力口熱輕4亦$會發生黏¥，從❿能以連續 穩定之張力狀態進行運送。其結果，能以比以往更高之 雨溫或高速進行膜之運送，可實現更高精度之轉印精度 -12- 201249668 或者因高速運送所帶來之生產性提高的效果。 另外’於成型用膜2之蛇行防止上，以不僅能防止膜 2之蛇行’還能防止模具3的蛇行較為適宜。這是因為於 在加壓轉印製程後之膜2與模具3保持密接之狀態下進行 運送之運送製程中，當模具3發生蛇行時，支撐於模具3 上之膜2亦一起發生蛇行，因此，會有自模具3脫模後之 運送變得不穩定之情況。本發明者等查明，於對由無端 環帶所構成之模具3進行加熱之加熱製程中，因模具3之 熱膨脹致使施加於模具3之張力變弱而產生鬆弛的情況 ，於是，當於模具3之寬度方向存在溫度不均時，因熱膨 脹之變異造成模具3之寬度方向的張力變得不均勻而產 生蛇行的情況。因此，針對為了防止模具3之蛇行，於懸 跨模具3之一方的輥之冷卻輥5具有檢測並控制施加於模 具3之張力及模具3的寬度方向位置之模具蛇行防止機構 的構成例，依圖進行說明。又，控制可為自動控制及手 動控制之任一者，但以自動控制較為適宜。 第4圖為顯示針對懸跨於加熱輥4與冷卻輥5之模具3 ，檢測及控制其張力變動及蛇行之模具蛇行防止機構的 第-構成例之概略俯視圖’第5圖為顯示自膜寬度方向觀 察同構成例之概略圖，第9圖為顯示藉由檢測模且3之蛇 行的蛇行檢測感測器24而進行之模具的寬度方向 量方法之概略圖。 無端環帶狀之模具3被懸跨於加熱輥4及冷卻觀5上 ’冷卻親5係設於能朝模具之運送方向平行地滑行移 架台15上。藉由架台15之移動，加熱輥4與冷卻輥5之間 -13- 201249668 的距離變化，施加於模具3之張力變化。架台丨5之移動係 藉由使伺服馬達1 7及進給螺桿1 8組合而成之可動手段！ 9 所執行架台1 5與可動手段19係透過荷重檢測器2 〇所連 釔。施加於模具3之張力係由此荷重檢測器20所檢測，且 以此檢測出之值形成於規定之範圍内的方式控制可動手 段19的移動量，以使模具3之張力保持一定。 另外’使支樓冷卻輥5之兩端的轴承1 3、1 4當中至少 一軸承U能在架台15上沿模具3之運送方向平行移動。軸 承14之移動係藉由使伺服馬達21及進給螺桿。組合而成 之可動手段23所執行，於模具3之寬度方向位置因蛇行而 發生偏移時，藉由此軸承14之移動，使冷卻輥5以軸承13 作為支點而傾動，以模具3之寬度方向位置成為中心的方 式進行修正。模具3之寬度方向位置的偏移係藉由蛇行檢 測感測器24所檢測，並根據此偏移量控制可動手段的 移動量，亦即冷卻輥5之傾動量，藉由冷卻輥5之傾動以 使模具3之寬度方向位置始終維持於中心。 藉由以上之模具蛇行防止機構，可防止因模具3之熱 膨脹所產生的張力之鬆弛、以寬度方向之溫度不均所造 成之張力不均等為起因的模具3之蛇行。於是，其於果， 於加壓轉印製程後之運送製程中，膜2不會追隨模具3而 發生蛇行，從而能以更為穩定且更高之生產性成型高精 度之細微構造轉印膜。 又，作為使架台15移動之可動手段，不限於伺服馬 達及進給螺桿，亦可使用以油壓或空氣壓作為作動流體 之流體壓汽缸。第6圖為顯示本發明之第二構成例的概略 -14- 201249668 俯視圖 &台1 5與流體壓汽缸2 5係透過荷重檢測器2 〇所 連、且根據以荷重檢測器2 0所檢測之值控制流體壓汽 缸25的壓力。於使用流體壓汽缸作為可動手段之情況亦 連結荷重檢測器的理由，係為了不受因汽缸之劣化所引 起的⑺動阻力的變動、作動流體之壓力不穩定的影響而 將模具之張力保持為一定，及為了於視覺上容易明白地 顯不杈具之張力。另外’第6圖之構成例顯示使支撐冷卻 軺· 5之轴承丨3、丨4的雙方分別能在架台丨5上移動之情況。 藉此，比只能移動一方之轴承的情況，能以更細微之精 度調整冷卻輥5的角度。 另外’於模具3之蛇行防止中使冷卻輥5傾動時，以 使罪近冷卻輥5之剝離輥7亦跟隨著發生傾動，使得冷卻 輥5與剝離輥7始終保持平行較為適宜。於剝離輥7相對於 冷卻輥5傾斜時，自模具3剝離成型用膜2時之剝離位置係 於寬度方向不同’因而會有於膜2之寬度方向產生剝離溫 度不均’或者產生因剝離張力之不均等而引起之膜2或模 具3的蛇行之情況。以圖針對用以使剝離輥7追隨冷卻輕5 之傾動的構成例進行說明。 第7圖為顯示本發明之模具之張力控制及蛇行防止 機構的第三構成例之概略俯視圖，第8圖為顯示自膜寬度 方向觀察之概略圖。 剝離輥7係於架台15上靠近冷卻輥5而平行設置，支 標剝離軺·

，其結果，膜2係於寬度方向上被以均勻之溫度及剝離張 力所剝離。 只是’作為此時之注意點，需要以剝離輥7之支點間 距離與冷卻輥5的支點間距離相等，且兩輥之中心位於模 具3之寬度方向中心截面上的方式設置。當未滿足這些條 件時，於使用可動手段23使冷卻輥5及剝離輥7傾動時， 兩輥之傾斜角度不同，因而不能保持平行。 ,又，於第7、第8圖中，剝離輥7係以成型用膜2對冷 卻輥5之抱角成為90度的方式所配置，但若是於〇〜18〇 度之範圍内的話，亦可配置於其他之位置。成型用膜2 對冷卻輥5之抱角越大，則膜2被冷卻之時間越長，從而 可充分地冷卻膜2。 以下，針對本發明之特徵的構成加壓成型部的加熱 輥4及軋輥6進行說明。 軋輥6係於芯層之外表面被覆有彈性層丨〇的構造。芯 層係要求具有強度及加工精度’例如適合採用鋼、織： 強化樹脂、陶竟、紹合金等。另外，彈性層1〇係藉由按 壓力而變形之層’以採用以橡膠為代表之樹脂層或彈性 體材質較為適宜。芯層之兩端部係藉由軸承"所旋轉支 撐，又，該車由承u係與汽虹等之按壓手段12連接。 係藉由此按壓手段12之衝輯開閉，挾壓或者開 用膜2。 & -16- 201249668 另外’乾報6亦可配合所需之製程或膜材質而具有調 機構。作為調溫機構，亦可為將輥内部設成中空而埋 入S形加熱器或感應加熱裝置’或者於内部加工成流路 而流動油、水或蒸氣等之熱媒，藉此，自輥内部加熱之 構& °另外’亦可為於輥外表面附近設置紅外線加熱器 ’自輥外表面加熱之構造。 以札親6之加工精度係kJIS b 〇621(改訂年1984)所 疋義之圓筒度公差上為〇 〇3inm以下，圓周振動公差上為 0.03mm以下較為適宜。當這些值太大時，於挾壓時之加 熱輥4與軋輥6之間形成局部間隙，所以，變得無法均勻 地按壓成型用膜2’而有於膜2之成型面2 &上產生轉印不 均的情況。另外’以彈性層1〇之表面粗度係以JIS b 〇6〇1( 改訂年2001)所定義之算術平均粗度以為16μιηα下較為 適且。這疋因為當Ra超過1.6 μιη時，會於按壓時產生彈性 層11之表面形狀轉印於膜2的背面之情況。 以軋輥6之彈性層1〇的耐熱性係具有i6〇t以上之耐 熱溫度較為適宜’又以具有1 801以上之耐熱溫度更為適 宜。在此，耐熱溫度係指於該溫度下放置24小時時的拉 伸強度的變化率超過1 〇 %時之溫度。 作為彈性層1 0之材質’於使用例如橡膠的情況下， 可使用矽酮橡膠、EDPM(乙烯丙烯二元橡膠）、氣丁橡膠 (neoprene)、CSM(氯磺化聚乙烯橡膠）、聚胺基曱酸酯橡 耀·、NBR(腈橡膠）、硬質橡膠（ebonite)等。於要求更g之 彈性率及硬度的情況下’作為壓光輥用樹脂，可根據各 橡膠製造商而使用對上述橡膠採用特殊處方者、或者使 201249668 動性提高之硬質耐壓樹脂（例如，聚酯樹脂）。 第1 〇圖為僅取出供給按壓力時之軋輥6而自成型用 膜2的寬度方向所觀察之概略圖。此時，於彈性層1 〇之厚 度方向上產生有變形量δ，伴隨此，軋輥6與成型用膜^ 係保持接觸寬度Β而進行接觸。為了控制彈性層1〇之變形 量δ，以彈性層1〇之橡膠硬度係依照ASTMd224〇: 2㈧' 邵氏硬度D)規格而處於70〜97。的範圍較為適宜。這是因 為若硬度低於70。時，彈性層11之變形量5增大，造成與 膜2之接觸寬度B變得過大，恐有無法確保細微構造之轉 印所需要的壓力之虞，另外，若硬度超過97。時，反過來 該層之變形量δ減小，造成接觸寬度B變得過小，恐有無 法確保細微構造之轉印所需要的按壓時間之虞。 其次，針對與軋輥6對向以挾壓成型用膜2及模具3 之加熱輥4進行說明。 加熱輥4係於軋壓時受到荷重，所以，要求具有強度 及加工精度，且其還具有加熱手段。作為材質，可考慮 例如鋼、纖維強化樹脂、陶瓷、鋁合金等。另外，作^ 加熱手段，亦可為藉由將内部作成中空而設置匣形加熱 态或感應加熱裝置，或者於内部加工流路而流動油、水 或洛氣等之熱媒，而自輥内部加熱之構造。另外，亦可 為於輥外表面附近設置紅外線加熱器或感應加熱裝置， 自輥外表面加熱之構造。 加熱輥4之加工精度亦與該軋輥6相同，以於JIS b 〇621(改訂年1984)所定義之圓筒度公差上為〇 〇3mm以下 ，圓周振動公差上為0.03mm以下較為適宜。當這些值太 * 18 - 201249668 大時，於挾廢時之加熱輕4與乾親6之間 戶:以，變得無法均勾地按壓成型用膜2,而有於膜二 5L : 2a上產生轉印不均的情況。另外，以加熱輥*之表面 粗度係依照JIS B 0601 (改訂年咖）所定義之算術平均 粗度以下較為適宜。這是因為當以超過 時，會產生加熱輕4之形狀轉印於模具3之背面，且㈣ 狀再被轉印於膜2之成型面2a的情況。 y 以於加熱輥4之表面實施鍍硬質絡、陶究溶射、類鑽 碳鐘膜等之高硬度皮膜㈣成處理較為適宜。這是因: 加熱輥4經常與模具3接觸而*受軋親6之按壓力’所以 =面非常容易磨損，當加熱輥4之表面磨耗或損傷時， ,產生如則述之成型用膜2的轉印不均或輥表面形狀 轉印至膜2的成型面以的問題。 ^作為本發明之特徵的加壓成型部之構成，係 於以加熱輥4及軋輥6使成型用膜2及模具3密接而予挾壓 之加壓轉印製程中，構成為滿^以下之⑴或⑺的 亦即， (1)成型用膜2之寬度係比模具3的寬度還寬，且於加 轉p製知中，成型用臈2之寬度方向兩端部係自埶 4分離。 ，、，、视 ^ (2)模具3之寬度係比成型用膜2之寬度還寬，且於加 :P製耘中，成型用膜2所受到加壓之區域的寬度係比 成型用膜2之寬度還窄。 =下，使用第2及3圖，針對本發明之加壓成型部的 構成詳細地進行說明。又，於第2及3圖中，將成型用臈2 -19- 201249668 所受到加壓之區域的寬度定義為w，將自被加壓之區域 的端至成型用膜2的端部之長度定義為v，如第2圖，於模 具3之寬度比軋輥6的寬度還窄之情況下，模具3之寬度成 為W，如第3圖’於軋輥6之寬度比模具3的寬度還窄之情 況下，軋輥6之寬度成為W。 使用第2圖，針對滿足（1)之條件時的加壓成型部之 構成進行說明。如第2圖所示’將成型用膜2之寬度設成 比模具3的寬度’即成型用膜2所受到加壓之區域的寬度 W更長。此理由係為了防止因軋輥6直接接觸於被加熱為 而溫之模具3的細微構造面3 a而造成的軋報6表面之彈性 層10的熱損傷、模具之細微構造面3a的傷痕的產生。於 是’以自模具3之寬度方向端部至膜2的寬度方向端部之 長度v為5〜15mm之範圍内較為適宜。這是因為當 5mm時，恐有因於膜2之運送中可能自然產生的略微之蛇 行而使得模具3與軋輥6直接接觸之虞。另一方面，當v 大於15mm時’相對於膜2之面積’所獲得之細微構造轉 印膜的面積減小，明顯造成收率降低，故而不理想。 於是’作為加熱輥4之表面構造，係於成型用膜2之 端部設置以膜2與加熱輥4不接觸之方式而予分離的區域 。作為分離之手段，係設置段差4a。以段差之高低差（分 離距離）H為10〜30mm之範圍内較為適宜，以自模具3之 知4至ί又差4a之距離11為1〜3mm之範圍内較為適宜。 本發明者等查明，於採用適用於本發明之高壓力條 件的製程中，在加壓部之端部，成型用膜2發生彎曲的現 象尤其明顯。因此，藉由於加熱輥4設置段差4a，可抑制 -20- 201249668 因’.¾•曲現象而挽曲之膜端部接觸及黏者於加熱概4上。膜 2係藉由軋親6而於非轉印面之寬度方向全面承受按堡力 ’相對於此，轉印面係僅於模具3之範圍内受到支樓。此 時’於膜2之比模具3更靠寬度方向外側的區域，產生以 模具3之寬度方向端部為支點的彎曲力矩，藉此，如第2 圖所示’成型用膜2之端部朝加熱輥4側彎曲。此時，藉 由將Η及υ設為上述適正之範圍，即使於產生有弯曲現象 之情況，膜2仍不會與加熱輥4接觸，可更為穩定地連續 成型膜。 於習知技術中，因無此分離部分，所以，於將模具3 及加熱輥4加熱為高溫進行運送時，加熱輥4與成型用膜2 局部發生黏著，致使膜2之運送張力於寬度方向變得不均 勻，而會較多地引起膜2之蛇行。於設置本構 分的轉印方法I即使將模具3及加熱輕4加：=: 連續轉印，膜2與加熱輥4亦不會發生黏著，從而能以連 續穩定之張力狀態進行運送。其結果，&以比以往更高 之高溫或高速進行膜之運送，可實現更高精度之轉印精 度或者因高速運送所帶來之生產性提高的效果。 接著’使用第3圖，針對滿足⑺之條件的情況之加 壓成型部之構成進行說明。如第3圖所示，將模具3之寬 度作成比成型用臈2之育声请玄 肤I見度還寬，且將軋輥6之加壓部的 寬度’即膜2所受到加壓之區域的寬度⑼作成比膜2之寬 度還窄。此理由係與⑴之條件相同，為了防止因模具3 與軋報6直接接觸而產生的彈性層1〇的熱損傷、模且之化 微構造面33的傷痕的產生。於是，以自軋輕6之加壓部的 -21 - 201249668 寬f方向端部至膜2的寬度方向端部之長度▽為5〜i5mm 之乾圍較為適宜。此理由亦與⑴之條件相同，是因為當 v低於5mm時，恐有因於膜2之運送中的略微之蛇行而二 得模具3與軋輥6接觸之虞’另一方面，當v大於15匪時 ，相對於膜2之面積，所獲得之細微構造轉印膜的收率明 顯降低。 本構成係藉由將模具3之寬度作成比成型用膜2之寬 度還寬，膜2於寬度方向全面受到模具3之支撐即使將 模具3及加熱輥4加熱為咼溫而連續轉印，膜2與加熱輥* 亦不會發生黏著’ &以連續穩定之張力狀態進行運送。 其結果，能以比以往更高之高溫或高速進行膜之運送， 可實現更尚精度之轉印精度或者因高速運送所帶來之生 產性提高的效果。 另外，於（1)及（2)之雙方的構成中，以於加壓部之寬 度方向端部使壓力漸漸地朝端部降低較為適宜。藉由使 端部之壓力降低，可緩和成型用膜2之端部的彎曲現象、 產生於加壓區域與非加壓區域之境界部的加壓痕跡，抑 制成型後之膜的平面性惡化、捲繞姿勢的混亂，從而能 以更為穩定之狀態連續地對膜進行運送及成型。 第1 1圖〜第1

(M) The apparatus for manufacturing a fine structure transfer film according to any one of the aspects of the present invention, wherein the roll diameter gradually decreases toward the outer side in the width direction at both end portions in the width direction of the roll. [Effects of the Invention] According to the present invention, a mold composed of an endless ring π having a fine structure formed on a surface thereof is pressed against a film composed of a plastic resin consisting of γ @ U ~ ^ 1 u μ pq 』 In the method and apparatus for manufacturing a fine structure transfer film in which a fine structure is continuously transferred to a surface, in the case of performing high-precision shape transfer at a high speed, the film does not become meandering and can be stably performed. By this, it is possible to manufacture a high-performance transfer film with high productivity. [Embodiment] The apparatus for manufacturing a fine structure transfer film of the present invention has at least an endless belt-shaped mold having a fine structure formed on the surface, and a pressurizing mechanism having at least a heating roller for heating the mold, a roller disposed in a flat surface with the heating roller and having an elastic surface coated thereon, and a rolling device using the two rollers; a cooling roller for cooling the mold; and a peeling mechanism for peeling and adhering to the mold a film on the mold; and a transport mechanism that rotates the heat roller and the cooling roller for transporting the mold; the manufacturing device of the fine structure transfer cartridge is characterized by: at a contact portion of the heat roller and the mold Both ends in the width direction have a difference in the surface of the heating roller so that the outer diameter of the roller is reduced in the width direction, or the width of the mold is wider than the width of the nipple pressing portion. Fig. 1 is a schematic cross-sectional view showing a manufacturing apparatus 观察 for observing a fine structure transfer film from the width direction of a film for forming an example of the embodiment of the present invention. As shown in Fig. 1, the apparatus 1 for manufacturing a fine structure transfer film of the present invention has the endless belt-shaped mold 3, the heating roller 4 and the cooling roller 5 suspended over the mold 3, and is parallel to the heating roller 4. A roll 6 that is configured to press-form a film, and a peeling roll 7 that peels the formed film from the mold 3 as a peeling mechanism. Further, the heating roller 4 and the roll 6 are preliminarily pressed by the two rolls while the mold 3 and the molding film 2 -10- 201249668 are laminated. Therefore, at least one of the rolls is connected to the pressing means i 2 It is composed of a pressurizing mechanism. Further, as a transport mechanism for transporting the mold 3 suspended over the heating roller 4 and the cooling roller 5, there is provided a driving means for rotationally driving the heating roller 4 and/or the cooling roller 5. Further, the transport device for the film 2 for molding has a take-up roll 8 and a take-up roll 9, and one or a plurality of guides (not shown) may be provided as needed. As a fine structure of the transfer film manufacturing apparatus, the film 2 for molding which is wound up from the take-up roll 8 is supplied to the mold 3 heated by the heat roller 4 while being pressed against the fineness of the mold 3 by the roll 6. The structural surface 3a is formed by transferring a shape corresponding to the surface shape of the mold 3, that is, a fine structure having a pattern opposite to the fine structure of the mold 3, to the molding surface 2a of the film 2, and then, the holding film 2 is in close contact with the mold 3. In the state, it is conveyed, cooled by the cooling roll 5, and then peeled off from the mold 3 by the peeling roller 7, and taken up on the take-up roll 9. This action is performed continuously. In the second and third aspects, the apparatus configuration of the press-molded portion in which the forming film 2 is pressed by the heating roll 4 and the pair of rolls 6 formed by the heating roll 4 will be described. Fig. 2 is a view showing a structure in which the width of the film for molding 2 is made wider than the width of the mold 3 and the step 4& is provided at both ends of the heating roller 4. In the pressure transfer process, when the roll 6 is in direct contact with the fine structural surface 3 a of the mold 3 heated to π temperature, thermal damage of the elastic layer 10 on the surface of the roll 6 is generated and a fine structural surface is generated. The problem of the scar of 3 a 'so' is preferable to make the width of the film 2 wider than the width of the mold 3 in order to prevent these problems from occurring. Therefore, by providing the step difference " -11-201249668 ', the both ends of the film 2 are separated from the heating roller *, so that the film 2 and the heating roller 4 are not partially adhered, and the film 2 can be suppressed from being snaked for stable transportation. Further, Fig. 3 is a schematic view showing a case where the width of the mold 3 is made wider than the width of the film for molding 2 and the width of the region pressed by the roll 6 is made narrower than the width of the film 2. Contrary to the configuration of Fig. 2, by making the width of the film 2 wider than the width of the pressing region of the roll 6, it is possible to prevent the fine structure surface 3a of the mold 3 from coming into direct contact with the roll 6 The elastic layer 1 is thermally damaged. Thus, by making the width of the mold 3 wider than the width of the film 2, the crucible 2 is entirely supported by the mold 3, so that the local adhesion of the film 2 to the heating pro 4 can be prevented. As a result, similarly to the configuration of Fig. 2, the film 2 can be prevented from being serpentine and stably transported. In the prior art, the width of the pressurizing region of the roll 6 is generally wider than the width of the mold 3. And the width of the film for molding 2 is made wider than the width of 'by this' The inventors of the present invention have found that the mold 3 and the heating roller 4 are heated to be in direct contact with the fine structure surface 3 a of the mold 3 to which the spacer is added. The high temperature is carried out in the region outside the width direction of the mold 3, and the heat roller 4 and the film 2 are locally adhered, so that the transport tension of the film 2 becomes uneven in the width direction, thereby causing the meandering of the film 2. The present invention relates to the film for molding 2, the mold 3, the heating roller 4, and the roll 6 so that the respective widths on the press-molded portions become the determined size, whereby the mold 3 and the heat roller 4 are formed at a high temperature. After the continuous transfer of the film 2 and the heat of the mouth, the heat is also increased by 4, and it can be transported in a continuously stable state. As a result, it can be carried out at a higher temperature or higher speed than ever before. Membrane transport can achieve higher precision transfer accuracy -12- 201249668 or productivity improvement due to high-speed transport. In addition, 'the prevention of the film 2 in the meandering prevents not only the film 2 Snake' can also prevent the snake 3 of the mold 3 This is because, in the transport process in which the film 2 and the mold 3 are kept in close contact with each other after the pressure transfer process, when the mold 3 is meandered, the film 2 supported on the mold 3 also snakes together. Therefore, the conveyance after the mold 3 is released from the mold 3 becomes unstable. The inventors have found that the heat expansion of the mold 3 is performed in the heating process for heating the mold 3 composed of the endless belt. When the tension applied to the mold 3 is weakened and slack occurs, when there is temperature unevenness in the width direction of the mold 3, the tension in the width direction of the mold 3 becomes uneven due to the variation in thermal expansion, and serpentine occurs. In the case of preventing the meandering of the mold 3, the cooling roller 5 of the roller which is one of the suspension molds 3 has a configuration example of the mold meandering prevention mechanism for detecting and controlling the tension applied to the mold 3 and the position in the width direction of the mold 3. According to the figure to explain. Further, the control may be either automatic control or manual control, but automatic control is preferred. Fig. 4 is a schematic plan view showing a first configuration example of a mold snagging prevention mechanism for detecting and controlling the tension fluctuation and the meandering of the mold 3 which is suspended over the heating roller 4 and the cooling roller 5, and Fig. 5 is a view showing the width of the film. The direction is observed as a schematic view of the configuration example, and FIG. 9 is a schematic view showing a method of measuring the width direction of the mold by the meandering detecting sensor 24 of the detecting die and 3. The endless belt-shaped mold 3 is suspended over the heating roller 4 and the cooling view 5. The cooling parent 5 is disposed on the shifting table 15 so as to be parallel to the conveyance direction of the mold. By the movement of the gantry 15, the distance between the heating roller 4 and the cooling roller 5 is changed from -13 to 201249668, and the tension applied to the mold 3 changes. The movement of the gantry 5 is a movable means by combining the servo motor 17 and the feed screw 18! 9 The gantry 15 and the movable means 19 are connected to the load detector 2 〇. The tension applied to the mold 3 is detected by the load detector 20, and the amount of movement of the movable hand 19 is controlled such that the detected value is formed within a predetermined range so that the tension of the mold 3 is kept constant. Further, at least one of the bearings 1 3 and 14 at both ends of the branch cooling roller 5 can be moved in parallel along the transport direction of the mold 3 on the gantry 15. The movement of the bearing 14 is performed by the servo motor 21 and the feed screw. When the combined movable means 23 is executed, when the position of the mold 3 in the width direction is shifted by the meandering, the cooling roller 5 is tilted by the bearing 13 as a fulcrum by the movement of the bearing 14, and the width of the mold 3 is used. Correction is made in such a way that the direction position becomes the center. The offset of the position of the mold 3 in the width direction is detected by the meandering detecting sensor 24, and the amount of movement of the movable means, that is, the amount of tilting of the cooling roller 5, by the tilting of the cooling roller 5 is controlled according to the offset amount. The position of the width direction of the mold 3 is always maintained at the center. According to the above-described mold meandering prevention mechanism, it is possible to prevent the slack of the mold 3 caused by the slack of the tension generated by the thermal expansion of the mold 3 and the unevenness of the tension caused by the temperature unevenness in the width direction. Therefore, in the conveyance process after the pressure transfer process, the film 2 does not follow the mold 3 and is serpentine, so that the fine transfer structure can be formed with higher precision and higher productivity. . Further, as a movable means for moving the gantry 15, it is not limited to the servo motor and the feed screw, and a fluid pressure cylinder using hydraulic pressure or air pressure as an actuating fluid may be used. Fig. 6 is a plan view showing a second configuration example of the present invention-14-201249668. The table 1 and the fluid pressure cylinder 25 are connected to the load detector 2, and are detected by the load detector 20. The value controls the pressure of the fluid pressure cylinder 25. The reason why the load cell is connected to the fluid pressure cylinder is also to prevent the tension of the mold from being affected by the fluctuation of the dynamic resistance (7) caused by the deterioration of the cylinder or the pressure instability of the operating fluid. Certainly, and in order to visually and easily understand the tension of the cookware. Further, the configuration example of Fig. 6 shows that both of the bearings 丨3 and 丨4 supporting the cooling 轺5 can be moved on the gantry 5, respectively. Thereby, the angle of the cooling roller 5 can be adjusted with finer fineness than when only one of the bearings can be moved. Further, when the cooling roller 5 is tilted during the meandering prevention of the mold 3, it is preferable that the peeling roller 7 of the chill roller 5 is also tilted so that the cooling roller 5 and the peeling roller 7 are always kept parallel. When the peeling roller 7 is inclined with respect to the cooling roll 5, the peeling position at the time of peeling the film for molding 2 from the mold 3 is different in the width direction, and thus peeling temperature unevenness may occur in the width direction of the film 2 or peeling tension may occur. The circumstance of the film 2 or the mold 3 caused by the unequality. A configuration example for causing the peeling roller 7 to follow the tilting of the cooling light 5 will be described. Fig. 7 is a schematic plan view showing a third configuration example of the tension control and meandering prevention mechanism of the mold of the present invention, and Fig. 8 is a schematic view showing the direction from the film width direction. The peeling roller 7 is attached to the gantry 15 in parallel with the cooling roller 5, and at least one of the bearings 27 and 27 of the detached y-7 bearing 27 is supported by the servo by the servo bearing one of the bearings The movable means 23 formed by the motor 2 1 and the feed screw 2 2 can be moved in parallel along the transport direction -15 - 201249668 of the mold 3 on the gantry 15. Therefore, when the chill roll 5 is tilted in order to prevent the squeezing of the mold 3, the peeling stick 7' connected to the same roller tilting means as the chill roll 5 follows the chill roll 5 and tilts. Therefore, the two rolls are always parallel. As a result, the film 2 was peeled off at a uniform temperature and peeling tension in the width direction. However, as the point of attention at this time, it is necessary to set the distance between the fulcrums of the peeling roller 7 to be equal to the distance between the fulcrums of the cooling rolls 5, and the centers of the two rolls are located on the central cross section of the mold 3 in the width direction. When these conditions are not satisfied, when the cooling roller 5 and the peeling roller 7 are tilted by the movable means 23, the inclination angles of the two rollers are different, and thus it is impossible to maintain parallel. Further, in the seventh and eighth drawings, the peeling roller 7 is disposed such that the wrap angle of the cooling roll 5 is 90 degrees in the film for molding 2, but if it is within the range of 〇18 to 〇, Can be configured in other locations. The larger the wrap angle of the film 2 for molding to the cooling roll 5, the longer the film 2 is cooled, so that the film 2 can be sufficiently cooled. Hereinafter, the heating roller 4 and the roll 6 constituting the press molding portion which are characteristic of the present invention will be described. The roll 6 is a structure in which the outer surface of the core layer is covered with an elastic layer. The core layer is required to have strength and processing precision. For example, steel, woven: reinforced resin, ceramic, and alloy are suitable. Further, the elastic layer 1 is preferably a layer which is deformed by pressure, and is preferably a resin layer or an elastomer material represented by rubber. Both ends of the core layer are supported by the rotation of the bearing, and the vehicle is connected by a pressing means 12 such as a steam bearing. The film 2 is opened or closed by the pressing of the pressing means 12, and the film 2 is pressed or opened. & -16- 201249668 In addition, the 'Report 6 can also be adjusted to match the required process or film material. The temperature control means may be a heat medium in which the inside of the roll is hollow and embedded in an S-shaped heater or an induction heating device or internally processed into a flow path to flow oil, water or steam. The internal heating structure & ° can also be used to provide an infrared heater near the outer surface of the roller to heat the outer surface of the roller. The machining accuracy of the Zao 6 is kJIS b 〇 621 (revised year 1984). The cylinder tolerance is 〇 3 inm or less, and the circumferential vibration tolerance is 0.03 mm or less. When these values are too large, a partial gap is formed between the heating roller 4 and the roll 6 at the time of rolling, so that the film for molding 2' cannot be uniformly pressed and the film 2 is formed on the molding surface 2 & Uneven transfer. Further, the surface roughness of the elastic layer 1 is preferably 16 μm α as defined by JIS b 〇6〇1 (Revised 2001). This is because when Ra exceeds 1.6 μm, the surface shape of the elastic layer 11 is transferred to the back surface of the film 2 at the time of pressing. It is preferable that the heat resistance of the elastic layer 1 of the roll 6 has a heat resistance temperature of i6 〇 or more or more, and it is more preferable to have a heat-resistant temperature of 1 801 or more. Here, the heat-resistant temperature means a temperature at which the rate of change in the tensile strength at a temperature of more than 1 〇 % when left at this temperature for 24 hours. As the material of the elastic layer 10, in the case of using, for example, rubber, fluorenone rubber, EDPM (ethylene propylene binary rubber), neoprene, CSM (chlorosulfonated polyethylene rubber), polyamine can be used. Base phthalate rubber, NBR (nitrile rubber), hard rubber (ebonite), and the like. In the case of the resin of the calender roll, it is possible to use a resin which is a special prescriber for the rubber or a hard pressure-resistant resin which improves the mobility of 201249668 (for example, polyester resin). The first plan view is a schematic view of the film 2 when the pressing force is applied and taken out from the width direction of the film 2 for molding. At this time, the amount of deformation δ is generated in the thickness direction of the elastic layer 1 , and the roll 6 and the molding film are brought into contact with each other by the contact width Β. In order to control the deformation amount δ of the elastic layer 1 , the rubber hardness of the elastic layer 1 is 70 to 97 in accordance with ASTMd224: 2 (eight) 'Shore hardness D). The scope is more appropriate. This is because if the hardness is lower than 70. At this time, the amount of deformation 5 of the elastic layer 11 is increased, and the contact width B with the film 2 is excessively large, and there is a fear that the pressure required for the transfer of the fine structure cannot be ensured, and the hardness exceeds 97. When the deformation amount δ of the layer is decreased, the contact width B becomes too small, and there is a fear that the pressing time required for the transfer of the fine structure cannot be ensured. Next, the heating roll 4 which presses the film 2 for press molding and the mold 3 with respect to the roll 6 is demonstrated. Since the heating roller 4 is subjected to a load at the time of rolling, it is required to have strength and processing precision, and it also has a heating means. As the material, for example, steel, fiber reinforced resin, ceramics, aluminum alloy, or the like can be considered. Further, the heating means may be a heat medium in which a crucible heating state or an induction heating device is provided by hollowing the inside, or a heat medium such as oil, water or Luo gas is flowed through the internal processing flow path, and the inside of the roller is used. Heated construction. Further, an infrared heater or an induction heating device may be provided in the vicinity of the outer surface of the roller to heat the outer surface of the roller. The processing precision of the heating roller 4 is also the same as that of the roller 6, and is preferably 〇3 mm or less in the cylindrical tolerance defined by JIS b 〇 621 (revised year 1984) and 0.03 mm or less in the circumferential vibration tolerance. When these values are too large * 18 - 201249668, the heating light 4 and the dry pro 6 are in the case of depletion: so that it becomes impossible to press the molding film 2 uniformly, and there is a film 2 5L : 2a A situation in which transfer unevenness occurs. Further, the surface roughness of the heating roller * is preferably in accordance with the arithmetic mean roughness defined by JIS B 0601 (Revised Yearbook). This is because when it is over, the shape of the heating light 4 is transferred to the back surface of the mold 3, and the (four) shape is transferred to the molding surface 2a of the film 2. y The surface of the heating roller 4 is preferably subjected to a high hardness film such as hard plating, ceramic dissolution, diamond-like carbon film, or the like. This is because: the heating roller 4 is often in contact with the mold 3 and is subjected to the pressing force of the rolling member 6 so that the surface is very easily worn, and when the surface of the heating roller 4 is worn or damaged, the film 2 for molding is produced as described above. The problem of uneven transfer or transfer of the surface shape of the roll to the molding surface of the film 2 is problematic. The structure of the press-molded portion which is a feature of the present invention is a press-transfer process in which the heating film 4 and the roll 6 are brought into close contact with each other by the heating roll 4 and the roll 6, and is configured to be full. (1) In the case of (1), the width of the film 2 for molding is wider than the width of the mold 3, and both ends in the width direction of the molding die 2 are separated from the crucible 4 in the case of the transfer p. (2) The width of the mold 3 is wider than the width of the film 2 for molding, and the width of the region where the film 2 for molding is subjected to pressurization in the addition: P is a film for molding. The width of 2 is also narrow. = Next, the configuration of the press-molded portion of the present invention will be described in detail using Figs. 2 and 3. Further, in the second and third figures, the width of the region to be pressurized by the molding 臈 2 -19 - 201249668 is defined as w, and the length from the end of the pressed region to the end portion of the film 2 for molding. Defined as v, as shown in Fig. 2, in the case where the width of the mold 3 is narrower than the width of the roll 6, the width of the mold 3 becomes W, as in Fig. 3, the width of the roll 6 is narrower than the width of the mold 3. In this case, the width of the roll 6 becomes W. The structure of the press-molded portion when the condition of (1) is satisfied will be described with reference to Fig. 2 . As shown in Fig. 2, the width of the film for molding 2 is set to be longer than the width W of the mold 3, that is, the width W of the region where the film for molding 2 is pressurized. The reason for this is to prevent thermal damage of the elastic layer 10 on the surface of the rolled surface 6 caused by the direct contact of the roll 6 with the fine structural surface 3 a of the mold 3 heated, and the generation of the flaw on the fine structural surface 3a of the mold. . Therefore, it is preferable that the length v from the end portion in the width direction of the mold 3 to the end portion in the width direction of the film 2 is in the range of 5 to 15 mm. This is because when 5 mm, there is a fear that the mold 3 and the roll 6 are in direct contact due to a slight snake which may naturally occur in the conveyance of the film 2. On the other hand, when v is larger than 15 mm, the area of the fine structure transfer film obtained with respect to the area of the film 2 is reduced, which is markedly caused to lower the yield, which is not preferable. Then, as the surface structure of the heating roller 4, a region where the film 2 and the heating roller 4 are not separated from each other is provided at the end portion of the film 2 for molding. As a means of separation, a step difference 4a is set. It is preferable that the height difference (separation distance) H of the step difference is in the range of 10 to 30 mm, and it is preferably within a range of 1 to 3 mm from the knowledge of the mold 3 to the distance 11 of the difference 4a. The inventors of the present invention have found that the bending of the film 2 for forming is particularly remarkable at the end portion of the pressurizing portion in the process of applying the high pressure condition suitable for the present invention. Therefore, by providing the step 4a of the heating roller 4, it is possible to suppress the film end contact and the adhesion of the -20-201249668 due to the phenomenon of '.3⁄4. The film 2 is fully subjected to the fortune force in the width direction of the non-transfer surface by the rolling of the parent 6 and the transfer surface is received by the branch only within the range of the mold 3. At this time, in the region outside the width direction of the mold 3 of the film 2, a bending moment is generated with the end portion in the width direction of the mold 3 as a fulcrum, and the end portion of the film 2 for molding is shown in Fig. 2 Bending toward the side of the heating roller 4. At this time, by setting Η and υ to the above-mentioned suitable range, even if a bending phenomenon occurs, the film 2 does not come into contact with the heating roller 4, and the film can be continuously formed more stably. In the prior art, since the separation portion is not provided, when the mold 3 and the heating roller 4 are heated to a high temperature for transportation, the heating roller 4 and the molding film 2 are locally adhered, so that the conveying tension of the film 2 is in the width direction. It becomes uneven, and it causes the film 2 to snake more. In the transfer method I for setting the constitution, even if the mold 3 and the heating light 4 are added: =: continuous transfer, the film 2 and the heating roller 4 are not adhered, and the film can be conveyed in a continuously stable tension state. As a result, & the film is transported at a higher temperature or higher speed than ever before, and the transfer precision with higher precision or the productivity improvement by high-speed transport can be achieved. Next, the configuration of the press-molded portion in the case where the condition of (7) is satisfied will be described using Fig. 3 . As shown in Fig. 3, the width of the mold 3 is made wider than the sound of the molding 臈2, and the width of the pressing portion of the roll 6 is the area where the film 2 is pressurized. The width (9) is made narrower than the width of the film 2. This reason is the same as the condition of (1), in order to prevent thermal damage of the elastic layer 1〇 caused by direct contact between the mold 3 and the rolling sheet 6, and generation of scratches on the microstructured surface 33. Therefore, it is preferable that the length ▽ of the end portion in the width direction of the -21 - 201249668 wide f direction of the press portion of the self-rolling light 6 to the end portion in the width direction of the film 2 is preferably 5 to i5 mm. This reason is also the same as the condition of (1), because when v is less than 5 mm, there is a fear that the mold 3 is in contact with the roll 6 due to a slight meandering in the conveyance of the film 2, on the other hand, when v is larger than At 15 Torr, the yield of the fine structure transfer film obtained was significantly lowered with respect to the area of the film 2. In the present configuration, the width of the mold 3 is made wider than the width of the film 2 for molding, and the film 2 is entirely supported by the mold 3 in the width direction. Even if the mold 3 and the heating roller 4 are heated to a temperature, the film is continuously transferred. 2 and the heating roller * will not be stuck ' & transport in a continuous stable tension state. As a result, the film can be transported at a higher temperature or higher speed than in the past, and the transfer precision with higher precision or the productivity improvement by high-speed transport can be achieved. Further, in the configuration of both of (1) and (2), it is preferable that the pressure gradually decreases toward the end portion at the end portion in the width direction of the pressurizing portion. By lowering the pressure at the end portion, it is possible to alleviate the bending phenomenon at the end portion of the film for molding 2 and the pressure trace generated in the boundary portion between the pressurized region and the non-pressurized region, thereby suppressing the deterioration of the planarity of the film after molding. The winding posture is disordered, so that the film can be continuously conveyed and molded in a more stable state. Figs. 1 to 1 show an example in which the pressure is lowered at the end portion of the pressurizing portion. Further, in each of the drawings, '(a) shows a configuration that satisfies the condition (1), and (b) shows an example when the condition (2) is satisfied. Fig. 1 is a schematic view showing the configuration of a press-molded portion when the roll diameter is gradually decreased at the end portion in the width direction of the heating roller 4. The amount of deformation of the elastic layer is gradually decreased toward the outer side in the width direction of the pressurizing portion, and the pressure applied by the film 2 for forming is also directed toward the width direction end of the pressurizing portion. The department is gradually decreasing. As a result, it is possible to alleviate the bending of the end portion of the film 2 and the pressure trace generated at the boundary portion between the pressurized region and the non-pressurized region. Fig. 12 shows that the thickness of the mold 3 is outward in the width direction at the end portion. The structure which is gradually reduced 'Fig. 3 shows a structure in which the diameter of the roll 6 is reduced toward the end in the width direction. In the same manner as the configuration of the second embodiment, the pressure applied to the film for molding 2 gradually decreases toward the end portion in the width direction of the pressurizing portion, so that the bending phenomenon of the end portion of the film 2 can be alleviated and generated. Pressurization marks at the boundary between the pressurized region and the non-pressurized region. The following describes the preferred pressurization conditions for the heating roller 4 and the roller 6.

When the parallelism tolerance is ηι and A i exceeds 0·1, the pressing force applied to the film 2 for molding will not be used in the 1* degree direction, etc. There is a case where a transfer unevenness or a meandering of the film 2 occurs. In the case of the pressure of the two rolls, the sum of the J and the code is that the area of the pressure applied to the film 2 is i ^ ν νν, and the inside of the W is 5 〇 μηη or less. Under 30μιη below ^...«g ,, and. When the amount of deflection exceeds 50 μm, the elastic layer 1 of the roll 6 becomes unable to follow the jerk! The pressing force becomes uneven. The pressure applied to the roll 6 under the preferred rolling pressure of the film 2 is as shown in Fig. 2 and Fig. 3, as shown in Fig. 2, and is provided by the pressing means 12 = forming 瞑 2 and roll 6 When the contact length is Β ° and the width of the region to be pressurized by the molding 赙 2 is -11-201249668, it is more suitable to set the external rolling 〇 defined by σ=ρ/ΒΨ to 8〇Mpa or more. More preferably, it is 100 MPa or more. Further, it is preferable that the pressing distance of the elastic layer 10, that is, the contact length 8 is 4 to be within the range of 5 to 7 mm. If the contact length B is narrower than 4 = mm, the fine structure transfer of the film 2 cannot be deprecated for a sufficient pressing time. On the other hand, if it is wider than 8 mm, it becomes difficult to ensure the 4 IL pressure at the value of the filling. Further, the P/w obtained by dividing the width w of the dusting region by the force P supplied to the roll is defined as the line pressure 'this value indicates the 挟 holding amount* applied per unit width. It is more suitable to have a line pressure P/W of 400 kN/m or more, and more preferably 5 〇〇 kN/n^. Next, other members of the manufacturing apparatus constituting the fine structure transfer film of the present invention will be described. The mold 3 is an endless belt in which a fine structural surface is machined. The material is preferably a metal having high strength and thermal conductivity. For example, nickel, steel, stainless steel, copper, or the like is suitable. Alternatively, it may be applied to the surface of the metal strip by a key. The ancient customs; the method of making the mold with a fine structure on the surface, and the method of making the metal coating directly on the surface of the metal crucible, the surface of the metal crucible is directly applied to the surface of the crucible. A method of cutting or laser processing, a method of electroforming a cylindrical shape having a fine inner surface, and a method of continuously attaching a thin plate having a fine structural surface to the surface of the force metal strip. The endless annular metal strip is a method of welding a metal sheet having a predetermined thickness and a length by a method in which the end portions of the metal sheets are butted to each other and the thickness of the metal sheet is a predetermined one-half ring shape, and the predetermined multiple is used. The length is welded to form an endless manufacturing. At this time, in consideration of the strength and workability of the metal strip -24 - 201249668, a thickness of 0.1 to 0 · 4 m m is preferable. If the thickness is smaller than this range, the metal tape may be broken or plastically deformed due to the tension supplied when the heating roller 4 and the cooling roller 5 are suspended. On the other hand, in the case where the thickness is larger than this range, the bending rigidity of the metal strip is too large, so that it becomes difficult to carry over the heating roller 4 and the cooling roller 5 or to be suspended over the rollers. . When the surface of the endless metal strip is plated, it is preferable that the material of the bell is nickel or copper. Further, it is preferable that the metal tape has a residence degree of 0.1 to 〇 3 mm and a plating thickness of 0.03 to 0.1 mm. If the thickness of the plating becomes larger than the thickness of the metal strip, there is a fear that peeling occurs at the interface between the metal strip and the plating. On the other hand, when the thickness of the right mineral deposit is too small, it is difficult to accurately process the fine structure. Hereinafter, an example of a method for producing an endless belt mold is shown. First, the ends of the thin stainless steel sheets were butted and welded, and processed into an endless metal strip. Next, the metal strip was fitted and fixed to the roller; Then, the machined η τ knife is machined into a forged layer of a metal strip by a grinder machine to process a predetermined fine structure. Then, the metal strip after the cutting of the τ && is removed from the roll, whereby a mold having a predetermined fine structure and endless s-belt is obtained. The fine structure of the 支 丄 丄 丄 13 13 13 13 13 13 13 13 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 The shape which is periodically repeated is suitable, and the 彳丨 ^ ^ column such as 'the groove which can be a triangular shape is arranged in a plurality of stripes, or It can be a rectangle, a semicircle or a semi-ellipse. Also, the -25- 201249668 slot does not need to be a straight line, but also a curved stripe pattern. Further, the ridge line direction is not limited to the circumferential direction of the belt, and may be the width direction. Further, the fine structure is not limited to being continuous in a straight line or a curved shape, and may be a convex shape or a concave shape in which a hemisphere, a cone, a rectangular parallelepiped or the like is discretely arranged in a dot shape. As shown in Figs. 4 and 5, the mold 3 is suspended over the heating roller 4 and the cooling roller 5, and the cold rolling roller 5 is placed on the gantry 15 in a state in which both ends of the bearings 13 and 14 are rotatably supported. . Thus, the gantry 15 is slidably moved in parallel by the slide rail 16 in the transport direction of the mold 3, whereby the gantry 15 provided with the chill roll 5 is moved, thereby adjusting the mold 3 suspended over the chill roll 5. The location of the shipping direction. At this time, it is preferable that the gantry 15 and the slide rail 16 are provided on the horizontal surface and the force is moved with a small resistance to the force in the movable direction. The gantry 15 is connected to the movable means 19 which combines the servo motor 17 and the feed screw 18 by the load detector 20, and the load detector 2 is attached to the force which is applied to the movable direction of the gantry 15, ie, the mold 3 is connected in the direction of the tension transmitted by the cooling rolls 5 provided on the gantry 15. Thereby, when the gantry 15 is moved so that the mold 3 is heated between the light 4 and the cooling light 5 in a state where tension is applied, the load detector 2 is loaded with the tension substantially equal to the tension applied to the upper and lower surfaces of the cookware 3. force. The servo and the load detection II 2G are connected by a control circuit (not shown), and the fluctuation of the detected value of the load detector 20 is controlled, and the motion I of the movable means 19 is controlled to be applied to the mold 3. The tension is always maintained - the position of the cooling roller 5 is adjusted in a fixed manner. The self-supporting cooling of the bearings at both ends of the Xingkun 5 will be provided on the gantry 15 and the hoisting motor 21 and the feed screw 22 will be combined with the heart -26-201249668. The movable means 23' can be further moved toward the mold on the gantry 15. The transport direction of 3 moves in parallel. At this time, the other bearing 13 is fixed to the gantry 15, and is moved by the carriage 14 on the gantry 15, and the chill roller 5 is rotated by the bearing 丨 3 as a fulcrum to tilt with respect to the heating roller 4. The position of the bearing 14 that determines the angle at which the cooling roller 5 is tilted is controlled in accordance with the position in the width direction of the mold 3, and in FIG. 4, the position of the bearing 14 when the heating roller 4 and the cooling roller 5 are parallel is used as a reference. When the position in the width direction of the mold 3 is shifted in the yl direction of Fig. 4, the bearing 14 moves in the XI direction, and when the mold 3 is displaced in the 72 direction, the bearing 14 moves in the direction of the χ2. The change in the position of the mold 3 in the width direction is monitored by the meandering detecting sensor 24. Fig. 9 is a schematic view showing the observation of the meandering detecting sensor 24 and the mold 3 from the downstream side of the film transporting direction. The snake-sampling detection sensor 24 is divided into a non-contact line type sensor such as a light-emitting side detection type 2 on the transmitting side 2 and a receiving side 2 servant type, and is blocked by a skin mold 3 which is one part of the transmission signal. The method is provided in such a manner as to cover the end portion of the mold 3 in the width direction. Then, the width direction position of the mold 3 is detected based on the magnitude of the signal amount received by the receiving side 24b. The servo motor 2 and the meandering detecting sensor 24 are connected by a control circuit (not shown), and the moving amount of the movable means 23 is determined in accordance with the detected value of the meandering detecting means 24, and the width of the cooker 3 is additionally used. The direction of the position is always within a predetermined range to control the angle of the cooling pro 5, preventing the mold 3 from being snaked. Further, as a means for tilting the :: roller 5, as shown in Fig. 6, the bearings 13 and 14 of the cooling roll 5 can be moved on the gantry B. Thereby, the angle of the cooling roll 5 can be adjusted more accurately than the condition of only one of the axes. Further, in order to accurately position the position of the mold 3 in the width direction, it is preferable to finely control the angle of the cooling roll 5, specifically, -27 - 201249668 to set the angular decomposition energy of the cooling roll 5 to "μ degrees". Here, the angular decomposition energy of the cooling roller 5 is a minimum amount of change in the angle of the rotation axis of the cold heading die 3 on the heating roller 4 when the cooling roller 5 is tilted for a suitable meandering correction: the rotation axis is opposite to 5 The angular decomposition can be set to 基准 by the position of the width direction of the cooling roller 3 not to be oscillated, and the reference position of the center of the mold during the meander correction. The gentleman is stunned and the force is applied to the straight result. 3 is always located in Ningshengxin, so that the film 2 can be formed stably and continuously. a. The angular decomposition energy of the cold portion roller 5 is obtained by using the bearing 13 as the moving side, and the second and second fulcrums. The distance between the bearing and the bearing is determined by the motion decomposition energy. For example, if the distance between the two is 60〇mm, then the right fulcrum, the angle of the cooling roller 5: the solution decomposition energy of the solution is °. 〇5_ when the knife is solved Approximately 0.0048 degree. In the cooling roll 5, water Mh which circulates water of a certain temperature by, for example, # has a water passage, and is continuously cooled by a cooling means of the type of ^ ^ 0 ^ a M , and the like. Yu Yu's with the door. ",, the heat conduction on the contact surface of the eight to cool the die peeling report 7 series and the cooling roller, glI Α roller 5 has the same built-in cooling means, from the back side of the cold rolling molding film 2, to send | 眭 ^ ^ \ Hui assists the function of peeling from the mold 3. At this time, when the cooling roll 5 is tilted while the meandering of the mold 3 is _, λ, and 10,000, the stripper 5 and the 7th roller 5 are tilted to always with the chill roll 5 In the manner of maintaining the parallelism, the action is more than 1 Τ. R ^ _ ”, the tilting of the peeling roller 7, for example, as shown in Figs. 7 and 8, the lamp is operated by the same means as the tilting of the 盥+7 roller 5 Alternatively, the peeling roller 7 has a structure in which the cooling roller 5 is pressed against the fluid pressure cylinder or the like. The pressing force of the J-engraving roller 7 for the film 2 for molding is not particularly limited, and -28-201249668, The surface of the surface and the film 2 for forming the roll 2 and the winding of the film 2 can be used to fix the structure of the film 2 for winding, the end portion and the motor, etc. I use the heart of the film 2, *Ma first knows the connection, and can rotate the speed-surface rotation. In addition, the control _,,, J is controlled by the torque to adjust the tension applied to the film 2 for molding. It is more suitable. The m supply and the light end are used; the fading red i & rA φ m ^ ^ bearing special rotation support" heating roller 4 system and motor 4 driving means &. £ &, slave connection, and can control the speed while rotating another 'to cool the lucky Kun 5 #, ft · ΗΗ: . ', through the flat mold by the driving force of the heating roller 4 to rotate is more appropriate. The speed of the transport is determined by the balance of the fine structure and the productivity of the formed film. However, in order to transfer the fine structure with high precision, the productivity is the same as the productivity. The range of ~3〇m/min determines the rex rabbit, the total + 疋 乂 is suitable. The driving method of the roll 6 is connected with the end of the heating 4 by a chain or a belt, and the heating roller 4 is rotated in conjunction with each other. Alternatively, it is preferable to use a motor that can be synchronized with the speed of the heating view 4 to rotate independently. However, as a structure that can be freely rotated, it can be rotated by friction with the film 2 for forming. It is designed according to the quality of the roller or the load, the rotation speed, etc., but it is preferable to use a self-aligning bearing as a bearing for supporting the cooling roller 5 and the peeling light 7. These rollers are not used for the self-aligning bearing. under, When the roller is tilted, the bearing may be damaged and the bearing may be damaged. The manufacturing method of the film having a fine structure on the surface using the device will be described. 201249668 The manufacturing apparatus for constructing a transfer film is sequentially processed through the following five processes under the conditions of (1) or (2) below, whereby a film having a transfer layer on at least one side is processed, and the fine structure is transferred. The printing film manufacturing device has an endless belt-shaped transfer mold which is suspended from the heating and cooling roller and has a fine structure on the surface; the mold heating process is surrounded by a mold having an endless belt-shaped surface formed with a fine structure on the surface. Heating is performed on the heated heating roller, and the pressure transfer process is performed by holding the pair of rollers including the heating roller in a state where the transfer side surface of the film is in close contact with the fine structure surface of the cooker Pressurizing; the transport process is carried to the cooling zone in a state in which the pressurization of the cookware is kept in close contact with the film; the cooling process is to keep the mold and the film dense in the cooling zone Since the state of the mold side into cold Ding He, peeling process, based mold and to cool the film after the peeling. In this condition (1), the width of the film is wider than the width of the mold, and in the X-press transfer process, both ends in the width direction of the film are separated from the β by the heat roller (2) The term "the width of the mold is wider than the width of the film" and the width of the region to which the film is pressurized is narrower than the width of the film during the pressure transfer process. An example of an embodiment of the present invention will be described using Figs. 1 to 4'. First, as a preparation stage of the manufacturing method, the film 2 for forming is taken out from the take-up roll 8, and in a state where the roll 6 is opened, the mold 3 which is suspended over the heat roller 4 and the cooling roll 5 passes through the peeling roll 7, The winding state is given by the take-up roll 9. Then, the film 2 for molding is conveyed at a low speed by a driving means, and the heating means of the heating roller 4 and the cooling means for cooling the Kyukon 5 are operated on the surface, and the surface temperature of the heating roller 4 and the cooling report 5 of -30-201249668 is adjusted. Warm to a given temperature. — The reason why the transport-surface is tempered is because if it is not transported, the portion of the film 2 on the heating roller 4 stores heat, and thus melts and ruptures. The condition of the surface temperature of the weight 4 and the surface temperature of the cooling member 5 depends on the material of the film 2 for molding, the shape of the fine structure of the mold 3, the aspect ratio, and the like, and the surface temperature of the heating roller 4 is set as the film. 2

In addition, it is more suitable to transport the quick-release in the temperature adjustment to 〇1 to 5 m/min, and to further increase the surface temperature of the heating roller 4 and the cooling roller 5 by 〇1 to lm/min (again, the surface temperature of the mold) The same temperature is the same as the following.) The temperature is adjusted to the set value, and then the same as the speed of the type:, the roll 6 is closed, and the film 2 and the mold 3 are pressed by the heat roller 4 and the roll 6. The opening/shape of the fine structure surface of the mold 3 is transferred to the molding surface 2a of the film 2. As a condition at this time, the molding speed of the film is set to 1 to 30 m/min, and the line pressure system is set to profit (10) (10) (7). In the above range, when the respective processes are arranged in accordance with the rotation of the mold, the continuous transfer of the film is composed of a mold heating process, a pressure transfer process, a transport process, a cooling system %, and a peeling process. The contact of the heating roller 4 is usually heated by heat conduction from the high temperature heating roller 4, and the temperature of the mold 3 is raised to the surface temperature of the heating roller 4 until the heating roller 4 and the roller 6 are pressed. (Mold heating process). The film 2 for molding is attached to the heating roller 4 The rolling portion of the roll 6 is pressed against and adhered to the heated mold -31 - 201249668. The resin of the softened constituent film is filled in the pattern of the fine structural surface 3a of the mold 3 (the pressure transfer process is The film pressed by the mold 3 is transported to the cooling zone (conveying process) while being kept in close contact with the mold 4. Here, the cooling zone indicates the range in which the die 3 is in contact with the cooling roll 5. In the cooling zone, the film is used by the film The heat transfer with the cooling roll 5 cools each of the molds 3 below the glass transition point of the resin constituting the film (cooling process). The cooled film is continuously peeled off from the cooling roll 5 by the peeling roll 7 Release (peeling process). The peeled film is wound on the take-up roll 9. Thus, in the press transfer process, as shown in Fig. 2, the width of the film 2 for molding is made into a mold. The width of 3 is also wide, and both ends in the width direction of the film 2 are separated from the heating roller 4. Alternatively, as shown in Fig. 3, the width of the mold k is made wider than the width of the film 2, and the zigzag 6 The width of the pressurizing portion is narrower than the width of the film 2. Thereby, the film 2 and the high temperature can be prevented from being added. * The direct contact 'prevents the surface of the end of the film 2 from being attached to the surface of the heating roller 4 due to high-temperature melting" is pulled toward the direction of rotation of the heating roller 4, so that the tension state of the film 2 is disturbed and serpentine occurs. In the pressure transfer process, it is preferable that the film 2 and the heating roller 4 are not in direct contact with each other. Further, during the process of manufacturing the fine structure transfer film by the method, the tension of the mold shown in Fig. 4 is controlled. And the meandering prevention mechanism, it is preferable to keep the tension and the width direction of the mold 3 within a predetermined range. By preventing the tension variation and the meandering of the mold 3, in the transportation process after the pressure transfer process, The film 2 is prevented from being caught by the meandering of the mold 3 and is snaked together. In addition to the above, in the pressure transfer process, the pressure may be applied to both ends in the width direction of the pressurizing region.
