201030200 六、發明說明： 【發明所屬之技術領域】 本發明係有關於申請專利範圍第1項的前言中所界定 的針織機及申請專利範圍第16項的前言中所界定的針座 【先前技術】 可被建構成圓的或平的針織機之針織機類型具有一針 座其被建構成一織針筒，織針盤，平的針板或類此者且被 設置多個溝槽。設置有針腳（butt )且被建構爲針舌（ latch)或複合織針的針織工具被可移動地安裝在該等構槽 內。具有圖樣之針織物的製造係由在至少一工作區內的針 織工具的針腳來達成，其中該至少一工作區被選擇性地分 布在由一凸輪的凸輪路徑所預先界定的至少兩個路徑中的 一個路徑上。這些路徑中的一個路徑將該等針織工具引導 〇 至一打算接受一紗線，一纖維束或類此者的位置，而另一 路徑則爲一俗稱無針織（no-knit)或穿通（run-through) 路徑，使得被該路徑引導的針織工具被會在各工作區內捲 取任何紗線或類此者（雙向技術）。此等配置主要適合彩 色圖樣的產品。然而，如果亦需要或只需要製造結構式圖 樣的話，則該凸輪提供一第三路徑，其引導爲此目的而被 選取之針織工具進入一掛針（tuck)位置（三向技術）。 爲了將該等針織工具依據圖樣分布在不同的路徑上， 圖樣或選擇裝置會被使用，它們有各種變化且用來作用在 -5- 201030200 該等針織工具上或推片（jack)選擇器，沉降片，控制彈 簧，彎折件或類此者，它們個別地與該等針織工具相關聯 ，且被設置在該等針織工具本身內或在該針座的相同溝槽 內，且它們可被機械地，氣動地，電性地，磁性地或電磁 地動作的元件個別地或連續地移動至兩個或三個位置中的 一個位置內，用以將相關聯的針織工具引導至兩個或三個 路徑中的一個路徑內（如，德國專利案DE 1585243A1， DE-PS 1 1 73 609 ， DE2 1 1 53 3 2C3 ， DE2 1 64632A1 ， DE3 7 1 2673 C1，DE 1 63 5 844C3，EP03 1 9007B 1 )。 因爲在高功率的針織機中每一用於針織工具的每一選 擇步驟必需發生在0.5毫秒至1.0毫秒的一極短的時間內 ，所以必需在彼此相鄰地被設置的針織工具，控制沉降片 或類此者上設置不同高度的針腳並在這些不同的高度的每 一高度提供一可個別地控制的選擇片形式之控制元件給選 擇機構（如，德國專利DE2117713C3)。因此，每一選擇 步驟可用的時間長度可被增加且可更加可靠地實施選擇程 序。 與依據圖樣選擇針織工具有關的一項尙未解決的問題 是發生在使用具有小的錠距（gauge)或高纖度（fineness )的針織機時。錠距被理解爲介於兩個彼此相鄰的針織工 具之間的平均間距，而纖度係指在針座內彼此相鄰的每一 英吋面積內的針數。因此，例如，E60的纖度係指每一英 吋內安排了 60根織針或5655個針織工具被設置在一直徑 爲30英吋的織針筒的周邊上，其可產生0.4 mm的錠距。 201030200 在E30的纖度下，一織物（web)或針織工具的厚度在此 例子中只有約〇.2mm而非0.4mm或更大。此等微小的針 織工具的確實選取可自相對低的機器速度下及/或用純機 械式操作的選擇機構來加以實施。然而，如果在高機器速 度下每一選擇步驟的時間長度只有〇·2毫秒至0.5毫秒的 話，一確實的選擇只有在該等針織工具，控制沉降片或類 此者上設置不同高度的針腳（如，上面的例子所述者）才 φ 能夠達成。然而，這是所不想要的，因爲它需要複雜的機 器構造。 然而，流行趨勢造成的結果是，針織物品的製造商不 只對具有纖度高達Ε60的針織機有愈來愈大的需求，還對 用於這些高纖度的選擇機構有愈來愈大的需求。爲了特定 的原因，到目前爲止只能用相當昂貴及/或慢工的針織機 來達成此需求。 只用凸輪部件來控制針織工具且沒有圖樣或選擇裝置 ® 的針織機是習知的。針織工具控制是由進入到凸輪區域中 的針腳來達成的（如，德國專利DP-PS53 5 1 73號）。詳 .言之，在此專利中，具有多個凸輪軌跡的凸輪是習知的， . —針織工具的針腳被引導於一個別的凸輪軌跡中。根據該 等針腳被安排在該等針織工具上的高度，這些針織工具每 一者都與一被選定的凸輪軌跡相關聯。例如，將針織工具 的針腳用一俗稱斜的或對角線的嵌入件在數個高度分布成 單一配置或雙配置是習知的（如，在 ITB Strickerei/-Wirkerei/Strickerei/Konfektion 1 976, vo 1. 2 pages 5 5-60 201030200 中的 Large plain circular knitting machine-patterning possibilities ( Part 1)”中描述者）。然而，用此類型 的凸輪部件的配置只能製造相對小的圖樣，再者，只藉由 更換或切換凸輪部件才能改變。因爲每一個別的針織工具 無法單獨地選擇，所以無法用此方式產生可自由選擇的圖 樣，到目前爲止只能使用前述的圖樣裝置來達成。 【發明內容】 q 有鑑於上述的先前技藝，構成本發明的基礎的技術問 題是要提出一種針織機及前述類型的針座，藉由此針織機 及針座，具有任何所想要之自由選擇的圖樣的針織物品當 想要有高纖度時可在沒有實質增加建造及成本支出下被製 造。 此問題可被本發明所解決，因爲該圖樣裝置被建構成 在每一選擇步驟中，在該針座內至少兩個彼此相鄰的針織 工具以相同的方式被同時選取且被引導進入至少兩個路徑 @ 中的同一路徑中。 本發明開始於由試驗證實的知識，例如，在用E5 0或 E60的高纖度製造的針織物品中，每一針跡（stitch)之 間都不相同的圖樣其理解方式與用E30或更低的纖度製造 的產品的理解方式是不相同的。因此，如果依據本發明， 在每一選擇步驟中，有兩個或更多個直接相鄰的針織工具 以相同的方式被同時選取，其所產生的實質好處爲’每一 選擇步驟可用的時間長度可因而被增加且針織工具的選擇 -8 - 201030200 可用與到目前爲止使用在低纖度的針織工 同的結構件。因此，具有高纖度之針織物 導致製造及成本支出的增加，或至少不會 樣只能在每兩個針跡或更多針跡之後才能 視覺上很難被察覺。 【實施方式】 φ 本發明將於下文中根據一圓形針織機 圓形針織機具有一直徑爲30英寸的可轉 了易於瞭解，一習知圓形針織機的結構及 描述’其後接著一依據發明加以建構之圓 部件的代表。 圖1顯示一圓形針織機其具有一普通 針座1，該針做被固定在一支撐環2上。 裝在一機器架（未示出）內且被提供一外 # 連接至一驅動齒輪（未示出），該驅動齒 達驅動。一凸輪被固定至一凸輪板4上， 不動地安裝於該機器架（未示出）上，該 支撐件5其環繞該針座1且其內側帶有多 凸輪段一個接著一個地被設置在該針座1 形成工作區或針織系統。圖2以從內側觀 此一凸輪段5 a。 該針座1具有多個由輻板6形成的溝 設置成平行於該針座1或織針筒的轉動軸 具上的結構件相 品的圖樣化不會 大幅地增加。圖 被改變的情況在 來詳下說明，該 動式織針筒。爲 操作方式首先被 形針織機的主要 的織針筒形式的 這被可轉動地安 齒輪緣3，其被 輪可被一驅動馬 該凸輪板被固定 凸輪具有一凸輪 個凸輪段，這些 的周圍方向上並 看的視圖來顯示 槽，這些輻板被 且接受針織工具 -9- 201030200 7，其被建構成一般的針舌織針。一選擇器8被設置在每 一針織工具7底下且在該針座1的同溝槽內。在該示範性 實施例中，該等針織工具7被設置在可平行於該轉動軸被 移動的溝槽內，而該等選擇器8則被安裝在可平行於該轉 動軸被移動且徑向地樞轉的溝槽內。 針織工具7及選擇器8具有分別用於其各自的下拉（ drawing-down)的針腳7a及8a，該等針腳具有下文所述 之相關聯的凸輪的下拉部件。該等選擇器8額外地被設置 有被固定於它們上或與它們被製造成一體之預拉緊的彈簧 9，用以在徑向上將它們預拉緊。 如圖2所示，每一凸輪段5a (其代表該圓形針織機 的工作區或針織系統）都具有一相關聯的選擇機構10, 其用來在以不同於純粹的凸輪式控制系統的方式實施相對 運動於針座1與凸輪支撐件5之間時，讓該等針織工具7 選擇性地運行通過不同的路徑，特別是一針織，掛針或無 針織（no-knit)或穿通（run-through)路徑。該選擇機構 10與該等選擇器8 —起形成一平常的圖樣裝置，具有色 彩及/或編織圖案的針織物品可用該圖樣裝置來製造。在 該示範性實施例中，該圖樣裝置用來實施俗稱三方技術（ 3 - way technique)。 如圖1及2所示，該等選擇器8包含雙臂式槓桿，其 具有第一槓桿臂11及第二槓桿臂12。圓角化的支承點14 被設置在槓桿臂11及12之間，該等選擇器藉由該支承點 被支撐在該針座1的溝槽的底部15上（圖1)。在此例 -10- 201030200 子中，在該示範性實施例中的配置使得第一槓桿臂11被 設置有一徑向朝外的錨面16(圖2)，針腳8a位在大約 與該支承點14相當的高度且該第二槓桿臂12具有兩個彼 此上下地設置之凸起來的針腳17及18，且與針腳8a相 類似地係徑向地朝外。又，在該選擇器8的上端，較佳地 被設置了 一被建構成支撐針腳19的面，其與位於上方的 針織工具7合作。該預拉緊的彈簧9被設置在該選擇器8 φ 之面向相關聯的溝槽的底部15的後側上，使得當該預拉 緊的彈簧被實質地放鬆時，該選擇器8被繞著該支承點 14樞轉，使得它的第一槓桿臂11抵靠該相關聯的溝槽的 底部15且該錨面16被撤回到該溝槽內，而在此同時’該 第二槓桿臂12被該預拉緊的彈簧9徑向朝外地預拉緊’ 該預拉緊的彈簧9被支撐抵靠該溝槽的底部15’使得凸 起來的針腳17，18從溝槽徑向朝外地突出。然而’如果 該預拉緊的彈簧9是如圖1所示地在拉緊狀態下的話’則 Ο 該第一槓桿臂U被朝外樞轉及該第二槓桿臂12被朝內樞 轉，使得該旄面16從該溝槽徑向朝外突出且凸起來的針 腳17，18被縮回至溝槽內。 根據圖2，兩個凸輪部20，21與在每一凸輪區5a內 的針織工具7的針腳7a相關聯，該二凸輪部彼此被上下 地設置且在它們之間留下一凹部22，該凹部的中央區內 被設置有一凸輪部23。被安排在各凸輪段5a的入口處的 的選擇機構10係被分別設置在凸輪部21底下的一個區域 中。在此例子中，“入口處”應被理解爲在針織工具7及 -11 - 201030200 選擇器8相對於凸輪移動於箭頭v (圖2)所示的相向上 時，各凸輪段5a首先被針織工具7及選擇器8接觸到的 開始處。此外，在選擇機構10底下的凸輪段5a具有一凸 輪部24，其與選擇器8的針腳8a相關聯且與凸輪部20， 21的方式相同地被設置有一凹部25及一分離的凸輪部26 。最後，一與選擇器8的針腳17，18相關聯且分別界定 一針織凸輪28及一掛針凸輪（tuck cam ) 29的凸輪部27 出現在凸輪部24的底下。該針織凸輪28係用來與下面凸 φ 起來的針腳17合作並將針腳17舉升至與一針織位置相對 應的高度。相反地，該掛針凸輪29用來與上面凸起來的 針腳合作並將針腳18舉升至與一掛針位置相對應的高度 〇 爲了確保在凸輪段5a的入口處獲得相同的選擇器8 樞轉位置，一壓力部3 0 (只能由圖1看到）分別被設在 每一凸輪段5a的入口處的前方，且該壓力部30從外面朝 內作用在該凸起來的針腳18上並將所有通過的選擇器8 © 樞轉至一個位置，在該位置上，該下槓桿臂12被樞轉回 入到針座1的溝槽內（圖1 )。 根據圖2，在此示範性實施例中，選擇機構1〇包括 兩個控制磁鐵31，32其在該針織工具7及選擇器8的運 行方向（箭頭v)上被設置成一個磁鐵接在一另一磁鐵之 後且一固持磁鐵33被設置在這兩個控制磁鐵31’ 32之間 且將它們磁極面連接成一平接頭。 上述圓形針織機的操作方法係實質上如下文所述： -12- 201030200 當一選擇器8跑入到該系統區5a中時，它首先進入 該按壓凸輪30的作用區內，該按壓凸輪根據圖】會壓在 其凸起來的針腳18上使得選擇器徑向的樞轉至該針座1 之相關聯的溝槽內且在此同時該錨面16壓抵住該選擇機 構10的磁鐵配置（參見圖1)。 如果控制磁鐵31被控制使得它沒有吸引該錨面1 6， 而是釋放該選擇器8的話，則選擇器會在該預拉緊彈簧9 φ 的影響下繞著該支承點14樞轉，使得附著在第二槓桿臂 1 2上的針腳1 7，1 8被徑向朝外運動並徑向地離開針座1 的溝槽。當進一步運動於箭頭v所示的方向上時，它們會 進入到該針織凸輪28的作用區內。因此，該凸起來的針 腳17跑到形成該針織凸輪28的凸輪部上使得相關聯的選 擇器8被垂直該箭頭v且平行於該針座1的轉動軸地舉升 (圖2的箭頭w)。該針織凸輪28被建構成在間頭v的 方向上長度足以使得該被選擇的選擇器8的支撐針腳19 φ 貼靠相關聯的針織工具7的下端且其針腳7a被抬高至該 分離的凸輪部23上方。這些針織工具7因而被額外地舉 高進入與針織位置相對應的最高位置並通過一針織路徑。 這在圖2中以粗黑的矩形塊所代表的針腳位置來顯示。 然而，如果第一控制磁鐵31被控制使得它持續吸引 該錨面16的話，則該錨面會傳遞至下面的固持磁鐵33上 ，使得相關聯的選擇器8留在該樞轉位置（參見圖1)且 在此樞轉位置被移動至該第二控制磁鐵32上。 如果在此時點上該第二控制磁鐵32被控制使得它沒 -13- 201030200 有吸引該錨面16，而是釋放該選擇器8的話，則選擇器 會在該預拉緊彈簧9的影響下繞著該支承點14樞轉，使 得附著在第二槓桿臂12上的針腳17，18被徑向朝外運動 。然而，因爲在此位置上，該凸起來的針腳17剛通過該 針織凸輪28的其方升高的部分，所以該凸起來的針腳17 停靠在面向它的該凸輪部27的內面上而沒有到達該針織 凸輪28。相反地，當它進一步前進時，該選擇器8的凸 起來的針腳18進入到該掛針凸輪29的作用區中，其將該 _ 凸起來的針腳18舉升至一與該掛針位置相當的高度，造 成各選擇器8的支撐針腳19將相關聯的針織工具7舉升 至一掛針路徑29a中。 然而，如果第二控制磁鐵32被控制使得它持續吸引 該錨面16的話，則該錨面會傳遞至下面的固持磁鐵34上 ，使得相關聯的選擇器8留在該樞轉位置（參見圖1)且 被移動通過該掛針凸輪29且沒有被它舉升。相關聯的針 織工具7的針腳7a然後通過一位在該分離的凸輪部23下 © 方的穿通路徑3 5。 在該等針織工具7分類進入針織’掛針或非針織或穿 通路徑28a，29a及35中的分類完成之後’所有的選擇器 8都被一作用針腳8a上的下拉凸輪36撤回且所有的針織 工具7都被一作用於其針腳7a上的下拉凸輪37下拉至圖 1所示的開始位置’使得一新的選擇處理可在後續的凸輪 段或系統中開始。 此類型的圓形針織機及圖樣裝置以及其進一步的細節 -14- 201030200 可從例如公開的德國公開案DE1032173 7A1號中獲得，該 案的內容藉由此參照被倂於本文中。 圖3及4示意地顯示在依據本發明的一目前認爲是最 佳的示範性實施例的圓形針織機的一針座及一圖樣裝置的 區域內的主要改變處。如從圖3中可看到的，一依據本發 明的圓形針織機包括一針座40 (，如一織針筒的形式） 其具有兩個區段40a及40b，它們在一中心軸41的方向 φ 上被設置成一個區段在另一個區段之上。多個徑向地突出 的第一腹板42 (其被設置成平行於該中心軸41且具有第 一溝槽43介於它們之間）被建構在該區段4 0a的周邊》 多個徑向地突出的第二腹板44(其被設置成平行於該中 心軸41且具有第二溝槽45介於它們之間）被建構在該區 段4 0b的周邊。一沒有腹板42及44且較佳地沿著整個織 針筒的周邊延伸的空隙或自由空間46被設置在區段40a 及40b之間。 # 第一溝槽係用來接受針織工具7(如圖4所示），這 些針織工具爲圖1及2所示之一般的針舌織針且具有針腳 7a。在另一方面，第二溝槽45係用來接受選擇器8,其 在示範性實施例中被建構成與圖1及2所示的選擇器8完 全相同。因此，相同的標號被使用於圖3及4的針織工具 7及選擇器8上。 然而，本發明與圖1及2所示之習知的圓形針織機主 要不同處係在於該等選擇器8係被建構及設置成具有纖度 其較佳地爲針織工具7的纖度的一半且該等第二溝槽45 -15- 201030200 被建構成其寬度約相當於兩個第一溝槽43及一個第一腹 板42的寬度的總合。例如，如果針織工具7具有E60的 纖度的話，則選擇器8被給予E30的纖度。如果針織工具 7具有E5 0的纖度的話，則選擇器8將被建構及設置成具 有E25的纖度。再者’該第一及第二腹板42，44及第一 及第二溝漕43，45係相關於比此被設置，使得兩個第一 溝槽43與一個第一腹板42被設置在一第二溝槽45的上 方，如圖3及4所示。這表示在針織工具7與選擇器8( ❹ 其具有相當於溝槽43及45的寬度的厚度）插入之後，兩 個相關聯的針織工具7(如，7x，7y)會位在一對應的選 擇器（如，8x)上方，如圖4所示。又，在另一方面，在 該配置中針織工具7的下端突伸至自由空間46中，而另 一方面，在每一選擇器8的上升期間，在針座40中兩個 直接彼此相鄰的針織工具（如，7x及7y)的下端同時停 靠在該相關聯的選擇器8x的上端上，其如圖4所示被較 佳地建構成一支撐針腳19。 @ 必需被額外地確保的是，由該支撐針腳19的頂面所 形成之介於針織工具7x，7y與選擇器8x之間的該支撐點 被設置成位在沒有腹板42，44及其它障礙物的自由空間 46下方很近處。這讓較厚的選擇器8的上端可被向上位 移超過第二溝槽45的上端，用以成對地停靠在相關聯之 較薄的針織工具（如，7x，7y)的下端’然後被進一步向 上移動用以針針織工具7以一種與圖2所描述的方式相同 的方式將針織工具7舉升起來並將它們移動進入該掛針路 -16 - 201030200 徑29a或針織路徑28a中。若沒有該自由空間46的話， 此示範性實施例將無法在選擇器8的上升運動期間將選擇 器放置抵靠針織工具7的下端，因爲這樣作選擇器會撞到 第一腹板42。 根據圖5所示之本發明的另一示範性實施例，所描述 的雙選擇係藉由相隔一腹板的第一腹板42 (如，42r，42s )來達成，這些第一腹板在其面向第二腹板44的下端於 φ 軸向方向上半延伸遠至該針座40的下區段40b，因而橋 接圖3及4所示的自由空間46。相反地，位在上述第一 腹板之間的第一腹板（如，421，42u )的長度則仍維持不 變，使得一自由空間46a被形成在被延長的第一腹板（如 ，42r，42s )之間，且該自由空間46a與圖4的自由空間 46 —樣是從第二腹板44的上端延伸至未延長的第一腹板 (如，42t，42u )的下端之間，因此是介於針座40的兩 個區段40a，40b之間。圖3及4所示的自由空間46在此 # 實施例中被分隔成多個側向被實質封閉的自由空間46a。 每一個自由空間46a都具有一寬度，此寬度實質上相當於 介於兩個第二腹板44之間的空間或介於兩個延長的第一 腹板（如，42r，42s)之間的空間。又，選擇器8的上端 被建構成讓它們可嵌入到介於被延長的第一腹板42的下 端之間的該自由空間46a中。整體而言，自有空間46a在 軸向上的大小被設計成足以容許選擇器8實施其最大的行 程，引導針織工具無障礙地進入針織位置。 否則，圖3至5所示的配置較佳地與圖2所示的配置 -17- 201030200 相同。這可藉由圖2所示的選擇器8的針腳17，18的厚 度爲針織工具7的針腳7a的厚度的兩倍可以清楚看出。 又，針織工具7的針腳7a的不同位置顯示出它們的選擇 永遠都是成雙地且同時地發生在直接相鄰的針織工具7上 。例如，兩對針腳7ai，7aj及7ak，7al與具有凸起來的 針腳17i或17k的選擇器8相對應，即一具有針腳17i或 1 7k的選擇器8分別將具有針腳7ai，7aj及7ak，7al的 兩個針織工具7舉升進入到該針織路徑2 8a中。在另一方 面’具有針腳17m或17〇的選擇器8(其被該選擇機構 10舉升於一穿通路徑中）將允許與它們相關聯之具有成 對的針腳7am，7an或7a，7ap的針織工具7亦通過該非 針織路徑35。最後，一具有針腳8r的選擇器8顯示出具 有針腳7ar，7a之兩個相關聯的的針織工具7被同時移動 進入到該掛針路徑29a中。 圖6顯示一示範性實施例，其實質地對應圖3及4的 示範性實施例。然而，與圖3及4的實施例相反的是，針 織工具48具有第一區段48a及第二區段4 8b，它們透過 設置在該自由空間46的過渡區4 8c而彼此相連接。第一 區段48a被設置在針座40由第一腹板42所形成的溝槽 43內。過渡區48c包含一些區段其係由針織工具48的柄 部的彎折區所形成且係用來將針織工具48的下端48d成 對地安排成彼此靠得比針織工具48由第一腹板42預先界 定的一般鍵距（gauge) tl更近。下端48b在距離上的縮 小讓在針座40的下區段40b內的第二腹板44的被選定的 201030200 厚度可以稍微大一些且讓針織工具48被建構在下端48d 上的面在舉升的操作期間不會有未以其全部表面被放置在 選擇器8的上表面上的風險。與圖3至5的示範性實施例 相同地，針織工具48被設置成具有一锭距tl其約爲選擇 器的錠距t2的一半。 圖7的示範性實施例（其與圖6相同的部分被標以相 同的標號）與圖6的實施例不同之處在於選擇器8完全被 φ 設置在由第二腹板44所形成的溝槽45內。爲了要容許如 此設計，雖然針織工具48的過渡區48 c仍被安排在該自 由空間46中，但針織工具48的第二區段481)被延長於針 座40的區段40b的方向上，使得它們突伸至由第二腹板 44所形成的第二溝槽45中且在這些溝槽中抵靠選擇器8 的上端面。這可提供的好處爲，在針織工具48的整個舉 升及下拉運動期間，下區段48b都被被引導至溝槽45中 ，如圖7中的選擇器8z所示，其已在一被舉升的狀態。 〇 因此，如果在該針織機的操作期間有更強的振動發生的話 ，針織工具48的下端48d也不會意外地滑離選擇器8的 上端面。 本發明的另一示範性實施例被示於圖8中。此實施例 與圖7的實施例不同處只要在兩個方面。 首先，每一針織工具48的長度只足以讓其下端區域 被一直地設置在第一溝槽43內。另一方面，包含圖7中 的第二區段48b及過渡區48c的部分被建構成分離的中間 推片（輔助推片）50’其具有朝向彼此被彎折成對的過渡 -19- 201030200 區50a。這些中間推片50的長度足以讓其上端50b突 到第一溝槽43中及其下端突伸至第二溝槽45中’第二 槽的寬度較佳地只比端部5〇c的寬度的兩倍稍大°中間 片50沿著被示意地顯示的接觸表面51或52被設置成 一端與針織工具48的下緣接觸及另一端與選擇器8的 緣接觸使得它們將運動傳遞至針織工具48(或反之亦 )° 其次，在一與圖5類似的方式中，相隔一腹板的第 腹板（如42r，42s )被延伸至針座40的區段40b中。 此例子中，該配置被加以選擇使得針織工具48的下端 域在其整個行程期間都被設置在第一溝槽43內’其向 的軸向長度是由未被延長的腹板（如，421，42u )來決 ，而選擇器8在其整個行程期間都被設置在第二溝槽內 又，在不同的運動行程期間，中間推片50被移動，使 其過渡區5 0a —直保持在自由空間46a內，因此不會撞 未被延長的第一腹板42 (如，42t，42u )。然而，中間 片50的上端50b及下端50c被永久地導引於第一溝槽 或第二溝槽45內。 最後，圖8顯示推片選擇器50的過渡區50a亦可 完全地或部分地被安排在第二溝槽45內，因爲第二溝 的寬度夠寬。 上述的中間推片50亦可被以類似的方式被提供在 6及7所示的示範性實施例中。 每一第一腹板（如，42r，42s)的對應延伸部亦可 伸 溝 推 其 上 然 在 下 定 〇 得 擊 推 43 被 槽 圖 被 201030200 提供在圖6及7所示的示範性實施例中，用以達到更佳的 針織工具48的下端區域引導效果。 以上所述的示範性實施例全都根據裝置與選擇器8 — 起工作的原則，與針織工具7, 48比較起來，該等選擇器 具有具有一加大的厚度，因此可根據圖樣使用一般的選擇 機構來加以選擇。然而，厚度約爲選擇器的厚度的一半的 針織工具被選擇器8成對地舉升（即，在電磁或類此者實 φ 施的每一選擇步驟之後），每一被舉升的選擇器8同時將 兩個相鄰的針織工具7舉升至一掛針或針織路徑中，例如 ，藉由所述的凸輪部來實施。因此，在一彩色或針織圖樣 中，在針織物中兩個彼此相鄰的針跡（stitch )應定是相 同的，即都是相同的顏色或針織架構。這在選擇器8的電 磁選擇上又特別的好處，即選擇處理可以有雙倍的時間且 選擇器8的厚度可被建構成比一般使用在高纖度針支工具 上之選擇器厚度厚。 9 如果選擇器8被建構成具有與針織工具7或48相同 的錠距且被設置在與針織工具相同的溝槽中的話，就可獲 得相同的優點。在此例子中，選擇機構可被建構成它可在 一選擇步驟中同時地將針座40中彼此相鄰的兩個選擇器 8樞轉或移動至一預定的位置》這被示意地顯示於圖9及 10中，其中一依據歐洲專利EP03 1 9007B1的圖樣裝置被 顯示。在此示範性實施例中，針織工具53被設置有接受 機構54,選擇器55被安裝於該接受機構中用以能夠樞轉 。在此例子中，該選擇係經由一電磁選擇機構56來實施 -21 - 201030200 ’該選擇機構具有一撞針（striking needle)形式的控制 元件57，其可移動於該等選擇器55的方向上。藉由該撞 針的尖端57a，一彈性撞擊會被施加在選擇器55上，如 以一種該選擇器會從圖9中實線所示的位置樞轉至圖9中 虛線所示的位置且造成下針腳55a被縮回至該接受機構 54內，而針腳55b則被樞轉出該接受機構55。相反地， 依據本發明，控制元件57的厚度是兩個選擇器55與一位 在這兩個選擇器55之間的腹板58的厚度的總和（圖1〇 )。或者，只提供該尖端57a此一厚度亦已足夠。藉由這 兩種結構，不同於以前在每一選擇步驟中的單一選擇，在 本發明中會有兩個在針座中彼此相鄰的針織工具53在同 一時間被選取且被引導至一被選定的路徑中。該控制元件 57必需被移動的頻率因而是每次撞擊只有一個選擇器55 被樞轉的頻率的一半而已。 一類似的圖樣裝置亦可用純粹的機械式機構來建構。 例如，以德國專利DE21 64632A1的圖樣裝置爲藍本，可 將每一控制元件製造成一被插入到一普通的圖樣鼓（ pattern drum )內的銷針，一凸輪或類此者，其寬度約爲 針座內兩個相鄰的針織工具的雙倍。在此例子中，該圖樣 裝置亦可在每一選擇步驟中藉由使用具有與針織工具的纖 度相應的纖度之選擇器及具有更高纖度之與其相關聯的控 制元件來選擇兩個針織工具。 本發明並不侷限於所描述的圓形針織機與針座的示範 性實施例，這些實施例可用各種方式來修改。這亦適用在 -22- 201030200 每一選擇步驟可被選擇的真織工具的數量上。與上文所描 述的雙選擇相反地’可在每一選擇步驟中同時選擇多於兩 個，如三個或四個，針織工具並將它們引導至同—路徑中 ，如針織路徑中。因此，很明顯地，本發明可以很容易地 應用到高纖度的針織機上’特別是纖度高於E40的針織機 。又’本發明並不侷限於所描述的選擇器，因爲其它的選 擇器及選擇元件亦可被用來取代它們。完全省掉選擇器並 φ 讓選擇機構及選擇元件直接作用在針織工具上亦是可能的 。除此之外’很明顯地’ ~據本發明的針織工具的選擇亦 可被應用在長械毛（p】ush)及/或高滅毛（high-pile)、針 織機以及平織機上的圖樣製造上，且本發明在圓形針織機 (其針座可被建構成一針盤形式）上實施特別有利。再者 ，其它的選擇機構或圖樣裝置亦可被使用。原則上，該選 擇機構可用任何所想要的方式來建構且用機械式機構、純 電子式機構，如使用彎折元件，氣動或電磁式機構來實施 φ 選擇器或控制元件的選擇。最後，應被瞭解的是，不同的 特徵亦可用不同於所描述及顯示的特徵的組合方式來應用 【圖式簡單說明】 本發明的進一步有利的特徵從附屬項申請專利範圍中 可以很容易看出。本發明將於下文中參照附圖中所示之示 範性實施例來加以詳細說明。 圖1爲通過習知設計的一織針筒及相關聯的凸輪的示 -23- 201030200 意徑向圖式 圖2爲從內部看到圖3中的工作區域內的凸輪的展開 圖上的圖式； 圖3爲依據發明的一圓形針織機的織針筒的立體圖； 圖4顯示圖3的織針筒的放大細部圖； 圖5至8爲通過依據本發明的織針筒的另外兩個示範 性實例的示意剖面圖； 圖9爲本發明的另一示範性實施例的示意徑向視圖； 及 圖10顯示沿著圖9的X-X線所取的剖面。 【主要元件符號說明】 1 :針座 2 :支撐環 3 :外齒輪緣 4 :凸輪板 5 :凸輪支撐件 6 :腹板 7 :針織工具 8 :選擇器 8a :針腳 7a :針腳 5a :凸輪段 1〇 :選擇機構 • 24- 201030200 1 1 :第一槓桿臂 12 :第二槓桿臂 1 4 :支承點 1 5 :底部 16 :錨面 1 7 :凸起來的針腳 1 8 :凸起來的針腳 φ 1 9 :支撐針腳 20 :凸輪部 2 1 :凸輪部 22 :凹部 23 :分離的凸輪部 24 :凸輪部 2 5 :凹部 26 :分離的凸輪部 φ 27 :凸輪部 2 8 :針織凸輪 2 9 :掛針凸輪 30:壓力部（按壓凸輪） 3 1 :控制凸輪 32 :控制凸輪 3 3 :固持磁鐵 9 :預拉緊的彈簧 2 8 a :針織路徑 -25 201030200 29a :掛針（無針織）路徑 34 :固持磁鐵 3 5 :穿通路徑 36 :下拉凸輪 37 :下拉凸輪201030200 VI. Description of the Invention: [Technical Field of the Invention] The present invention relates to a knitting machine as defined in the preamble of claim 1 and a preamble as defined in the preamble of claim 16 [Prior Art] A type of knitting machine that can be constructed to form a round or flat knitting machine has a needle holder that is constructed to form a knitting needle, a needle disc, a flat needle board or the like and is provided with a plurality of grooves. A knitting tool provided with a butt and constructed as a latch or a composite needle is movably mounted in the slots. The manufacture of the knitted fabric having the pattern is achieved by the stitching of the knitting tool in at least one working zone, wherein the at least one working zone is selectively distributed in at least two paths predefined by the cam path of a cam On a path. One of these paths directs the knit tool to a position intended to receive a yarn, a fiber bundle or the like, and the other path is a no-knit or punch-through (run) -through) The path so that the knitting tool guided by the path will take up any yarn or the like in each work area (two-way technology). These configurations are primarily suitable for products with color patterns. However, if a structural pattern is also required or only required, the cam provides a third path that directs the selected knitting tool for this purpose into a tuck position (three-way technique). In order to distribute the knitting tools on different paths depending on the pattern, patterns or selection devices are used, which have various variations and are used to act on the knitting tools or jack selectors on -5 - 201030200, a sinker, a control spring, a bend or the like, which are individually associated with the knit tool and are disposed within the knit tool itself or within the same groove of the hub and they can be Mechanically, pneumatically, electrically, magnetically or electromagnetically moving elements are individually or continuously moved into one of two or three positions for guiding the associated knitting tool to two or Within one of the three paths (eg, German Patent No. DE 1585243 A1, DE-PS 1 1 73 609 , DE 2 1 1 53 3 2 C3 , DE 2 1 64632 A1 , DE 3 7 1 2673 C1, DE 1 63 5 844 C3, EP03 1 9007B 1). Since each selection step for a knitting tool in a high power knitting machine must occur at 0. 5 milliseconds to 1. 0 milliseconds in a very short period of time, so it is necessary to set the stitches of different heights on the knitting tools that are placed adjacent to each other, or to provide a different height at each of these different heights. The control element in the form of a selected piece is controlled by a selection mechanism (for example, German Patent DE 2117713 C3). Therefore, the length of time available for each selection step can be increased and the selection procedure can be implemented more reliably. An unresolved problem associated with selecting a knitting tool in accordance with the pattern is when using a knitting machine having a small gauge or high fineness. The spindle pitch is understood to be the average spacing between two knitting tools adjacent to each other, and the fineness refers to the number of stitches in each inch of the area adjacent to each other within the hub. Thus, for example, the fineness of the E60 means that 60 needles or 5,655 knitting tools are arranged in each inch to be placed on the periphery of a 30 inch diameter knitting needle cylinder, which produces 0. 4 mm spindle distance. 201030200 Under the denier of E30, the thickness of a web or knitting tool is only about 〇 in this example. 2mm instead of 0. 4mm or more. The selection of such tiny needle tools can be implemented at relatively low machine speeds and/or with a purely mechanically operated selection mechanism. However, if at high machine speeds, the length of each selection step is only 〇·2 milliseconds to 0. For a period of 5 milliseconds, a definitive choice can only be made by setting the stitches of different heights (such as those described in the example above) on the knitting tool, the control sinker or the like. However, this is not desirable because it requires complex machine construction. However, the result of fashion trends is that manufacturers of knitted goods are not only increasingly demanding for knitting machines with deniers up to Ε60, but also have an increasing demand for these high-density selection mechanisms. For a specific reason, so far only a relatively expensive and/or slow-working knitting machine has been used to achieve this. Knitting machines that use only cam components to control the knitting tool and that do not have a pattern or selection device ® are conventional. The knitting tool control is achieved by the stitches entering the cam area (e.g., German Patent DP-PS53 5 1 73). Detailed . In other words, in this patent, a cam having a plurality of cam tracks is conventional. - The stitches of the knitting tool are guided in a different cam track. Each of these knitting tools is associated with a selected cam track based on the height at which the stitches are arranged on the knitting tools. For example, it is conventional to distribute the stitching of a knitting tool in a single configuration or a dual configuration at a number of heights using a commonly known oblique or diagonal insert (e.g., at ITB Strickerei/-Wirkerei/Strickerei/Konfektion 1 976, Vo 1. 2 pages 5 5-60 described in Large plain knitting machine-patterning possibilities (Part 1) in 201030200. However, the configuration of this type of cam component can only produce relatively small patterns, and again, only borrow It can be changed by replacing or switching the cam member. Since each individual knitting tool cannot be individually selected, it is impossible to produce a freely selectable pattern in this way, and so far it can only be achieved by using the aforementioned patterning device. In view of the foregoing prior art, the technical problem underlying the present invention is to propose a knitting machine and a hub of the type described above, whereby the knitting machine and the hub are knitted with any desired freely selected pattern. The article can be manufactured without substantial added construction and cost when it is desired to have a high denier. This problem can be solved by the present invention because the pattern device is constructed in each of the selection steps, at least within the hub Two knitting tools adjacent to each other are simultaneously selected in the same manner and guided into at least two paths @ In the course of the invention, the invention begins with experimentally proven knowledge, for example, in a knitted article made of a high denier of E50 or E60, the pattern of the difference between each stitch is understood and used. The product of E30 or lower denier is understood to be different in the way. Therefore, according to the invention, in each selection step, two or more directly adjacent knitting tools are simultaneously The substantial benefit of the selection is that the length of time available for each selection step can thus be increased and the choice of knitting tool -8 - 201030200 can be used with the structural members used so far in low denier knits. Knitted fabrics with high denier result in increased manufacturing and cost, or at least not visually difficult to detect after every two stitches or more. [Embodiment] φ The present invention will In the following, according to a circular knitting machine, a circular knitting machine has a diameter of 30 inches which can be easily rotated. The structure and description of a conventional circular knitting machine are followed by a basis. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows a circular knitting machine having a conventional needle holder 1 which is fixed to a support ring 2. Mounted in a machine frame (not shown) and An outer gear # is provided to be coupled to a drive gear (not shown) for driving the drive. A cam is fixed to a cam plate 4 and is fixedly mounted to the machine frame (not shown), the support member 5 It surrounds the hub 1 and has a plurality of cam segments on its inner side, one after the other, which are arranged to form a working area or a knitting system. Figure 2 views the cam segment 5a from the inside. The hub 1 has The patterning of the plurality of grooves formed by the webs 6 arranged parallel to the hub 1 or the rotating shaft of the knitting cylinder does not greatly increase. The situation in which the figure is changed is explained in detail below, the moving knitting needle. This is rotatably mounted in the form of a main knitting needle of the knitting machine, which is rotatably mounted on the gear rim 3, which is driven by a wheel. The cam plate is fixed by a cam having a cam cam segment, the circumference of these Views in the direction and view to show the grooves, these webs are accepted and accepted by the knitting tool -9- 201030200 7, which is constructed as a general needle knitting needle. A selector 8 is disposed under each of the knitting tools 7 and within the same groove of the hub 1. In the exemplary embodiment, the knitting tools 7 are disposed in grooves that are movable parallel to the axis of rotation, and the selectors 8 are mounted to be movable parallel to the axis of rotation and radially The ground is pivoted inside the groove. Knitting tool 7 and selector 8 have stitches 7a and 8a for their respective pull-downs, respectively, which have pull-down members for the associated cams described below. The selectors 8 are additionally provided with pretensioned springs 9 that are fixed to them or made integral with them for pretensioning them in the radial direction. As shown in Figure 2, each cam segment 5a (which represents the working area or knitting system of the circular knitting machine) has an associated selection mechanism 10 for use in a system different from a pure cam control system. When the relative movement between the needle hub 1 and the cam support 5 is effected, the knitting tools 7 are selectively operated through different paths, in particular a knitting, hanging needle or no-knit or punch-through ( Run-through) path. The selection mechanism 10 forms a conventional pattern device together with the selectors 8, and a knitted article having a color and/or a woven pattern can be manufactured using the pattern device. In the exemplary embodiment, the patterning device is used to implement a three-way technique. As shown in Figures 1 and 2, the selector 8 includes a dual-arm lever having a first lever arm 11 and a second lever arm 12. The filleted support points 14 are disposed between the lever arms 11 and 12, and the selectors are supported by the support points on the bottom 15 of the groove of the hub 1 (Fig. 1). In this example -10-201030200, the configuration in the exemplary embodiment is such that the first lever arm 11 is provided with a radially outwardly facing anchor surface 16 (Fig. 2) with the stitch 8a positioned approximately at the support point 14 is of a comparable height and the second lever arm 12 has two raised pins 17 and 18 arranged one above the other and radially outwardly similar to the stitch 8a. Further, at the upper end of the selector 8, a face constructed to support the stitch 19 is preferably provided, which cooperates with the knitting tool 7 located above. The pretensioned spring 9 is disposed on the rear side of the bottom 15 of the selector 8 φ facing the associated groove such that when the pretensioned spring is substantially relaxed, the selector 8 is wound The support point 14 pivots such that its first lever arm 11 abuts the bottom 15 of the associated groove and the anchor face 16 is withdrawn into the groove while at the same time 'the second lever arm 12 is pretensioned radially outward by the pretensioned spring 9 'The pretensioned spring 9 is supported against the bottom 15' of the groove such that the raised pins 17, 18 are radially outward from the groove protruding. However, 'if the pretensioned spring 9 is in the tensioned state as shown in Fig. 1' then the first lever arm U is pivoted outward and the second lever arm 12 is pivoted inwardly, The jaws 16 are projected radially outwardly from the groove and the raised pins 17, 18 are retracted into the grooves. According to FIG. 2, the two cam portions 20, 21 are associated with the stitches 7a of the knitting tool 7 in each cam region 5a, which are arranged one above the other and leave a recess 22 between them, which A cam portion 23 is provided in the central portion of the recess. The selection mechanisms 10 arranged at the entrance of each cam segment 5a are respectively disposed in an area under the cam portion 21. In this example, "inlet" should be understood to mean that each cam segment 5a is first knitted when the knitting tool 7 and -11 - 201030200 selector 8 are moved relative to the cam in the phase shown by the arrow v (Fig. 2). The tool 7 and the selector 8 are in contact with the beginning. Further, the cam segment 5a under the selection mechanism 10 has a cam portion 24 which is associated with the stitch 8a of the selector 8 and which is provided with a recess 25 and a separate cam portion 26 in the same manner as the cam portions 20, 21. . Finally, a cam portion 27 associated with the stitches 17, 18 of the selector 8 and defining a knitting cam 28 and a tug cam 29, respectively, appears underneath the cam portion 24. The knitting cam 28 is used to cooperate with the stitches 17 of the lower convex φ and lift the stitches 17 to a height corresponding to a knitting position. Conversely, the hook cam 29 is used to cooperate with the raised stitches and lift the stitches 18 to a height corresponding to a needle position to ensure that the same selector 8 is obtained at the entrance of the cam segment 5a. In the turning position, a pressure portion 30 (only visible in Fig. 1) is respectively provided in front of the entrance of each cam segment 5a, and the pressure portion 30 acts on the raised stitch 18 from the outside toward the inside. All of the passed selectors 8 © are pivoted to a position in which the lower lever arm 12 is pivoted back into the groove of the hub 1 (Fig. 1). According to Fig. 2, in this exemplary embodiment, the selection mechanism 1 includes two control magnets 31, 32 which are arranged in a running direction (arrow v) of the knitting tool 7 and the selector 8 to form a magnet. A further magnet and a holding magnet 33 are disposed between the two control magnets 31'32 and connect their pole faces to a flat joint. The operation method of the circular knitting machine described above is substantially as follows: -12- 201030200 When a selector 8 runs into the system area 5a, it first enters the active area of the pressing cam 30, the pressing cam According to the figure, it is pressed against the raised stitch 18 such that the selector pivots radially into the associated groove of the hub 1 and at the same time the anchor face 16 presses against the magnet of the selection mechanism 10. Configuration (see Figure 1). If the control magnet 31 is controlled such that it does not attract the anchoring surface 16, but releases the selector 8, the selector pivots about the bearing point 14 under the influence of the pretensioning spring 9φ, so that The pins 17, 7 8 attached to the second lever arm 12 are moved radially outward and radially away from the groove of the hub 1. When moving further in the direction indicated by the arrow v, they will enter the active area of the knitting cam 28. Therefore, the raised stitch 17 runs onto the cam portion forming the knitting cam 28 such that the associated selector 8 is lifted perpendicular to the arrow v and parallel to the axis of rotation of the hub 1 (arrow w of Fig. 2) ). The knitting cam 28 is constructed to be of sufficient length in the direction of the head v such that the support stitch 19 φ of the selected selector 8 abuts the lower end of the associated knitting tool 7 and its stitch 7a is raised to the separation Above the cam portion 23. These knitting tools 7 are thus additionally raised into the highest position corresponding to the knitting position and passed through a knitting path. This is shown in Figure 2 by the position of the stitches represented by the thick black rectangular blocks. However, if the first control magnet 31 is controlled such that it continues to attract the anchoring surface 16, the anchoring surface is transferred to the underlying holding magnet 33 such that the associated selector 8 remains in the pivoting position (see figure). 1) and moved to the second control magnet 32 at this pivot position. If at this point the second control magnet 32 is controlled such that it does not attract the anchoring surface 16, but releases the selector 8, the selector will be under the influence of the pretensioning spring 9. The pivoting point 14 is pivoted such that the stitches 17, 18 attached to the second lever arm 12 are moved radially outward. However, since the raised stitch 17 just passes through the raised portion of the knitting cam 28 in this position, the raised stitch 17 rests on the inner face of the cam portion 27 facing it without The knitting cam 28 is reached. Conversely, as it advances further, the raised stitch 18 of the selector 8 enters the active area of the hang-on cam 29, which lifts the _ raised pin 18 to a position comparable to the hang-up position The height of the support pins 9 of each selector 8 lifts the associated knitting tool 7 into a needle path 29a. However, if the second control magnet 32 is controlled such that it continues to attract the anchoring surface 16, the anchoring surface will be transferred to the underlying holding magnet 34 such that the associated selector 8 remains in the pivoting position (see figure). 1) and moved through the hook cam 29 without being lifted by it. The stitch 7a of the associated knitting tool 7 is then passed through a one-way through path 35 under the separated cam portion 23. After the sorting of the knitting tools 7 into the knitting 'needle or non-knit or pass-through paths 28a, 29a and 35' is completed, all of the selectors 8 are withdrawn by the pull-down cam 36 on an active stitch 8a and all the knitting The tool 7 is pulled down by a pull-down cam 37 acting on its stitch 7a to the starting position shown in Figure 1 so that a new selection process can begin in a subsequent cam segment or system. A circular knitting machine and a patterning device of this type, and further details thereof, are disclosed in, for example, the published German publication No. DE 10 32 173 7 A1, the disclosure of which is incorporated herein by reference. Figures 3 and 4 show schematically the major changes in the area of a hub and a patterning device of a circular knitting machine in accordance with an exemplary embodiment of the present invention which is presently considered to be the best. As can be seen from Figure 3, a circular knitting machine in accordance with the present invention includes a hub 40 (as in the form of a needle cylinder) having two sections 40a and 40b on a central axis 41. The direction φ is set to one segment above the other segment. A plurality of radially projecting first webs 42 (which are disposed parallel to the central axis 41 and having a first groove 43 interposed therebetween) are constructed at the periphery of the section 40a" A second web 44 projecting to the ground, which is disposed parallel to the central axis 41 and having a second groove 45 interposed therebetween, is constructed around the periphery of the section 40b. A void or free space 46 having no webs 42 and 44 and preferably extending along the periphery of the entire woven cylinder is disposed between the segments 40a and 40b. #第一槽 is used to receive the knitting tool 7 (shown in Figure 4), which is a general needle knitting needle shown in Figures 1 and 2 and has a stitch 7a. In another aspect, the second trench 45 is adapted to accept the selector 8, which in the exemplary embodiment is constructed identically to the selector 8 shown in Figures 1 and 2. Therefore, the same reference numerals are used for the knitting tool 7 and the selector 8 of Figs. However, the main difference between the present invention and the conventional circular knitting machine shown in Figures 1 and 2 is that the selectors 8 are constructed and arranged to have a fineness which is preferably half the fineness of the knitting tool 7 and The second grooves 45 -15 - 201030200 are constructed to have a width which corresponds approximately to the sum of the widths of the two first grooves 43 and one of the first webs 42. For example, if the knitting tool 7 has a fineness of E60, the selector 8 is given the fineness of E30. If the knitting tool 7 has a fineness of E50, the selector 8 will be constructed and arranged to have a fineness of E25. Further, the first and second webs 42, 44 and the first and second gullies 43, 45 are associated with each other such that the two first grooves 43 and one of the first webs 42 are disposed. Above a second trench 45, as shown in Figures 3 and 4. This means that after the knitting tool 7 and the selector 8 (which have a thickness corresponding to the width of the grooves 43 and 45) are inserted, the two associated knitting tools 7 (e.g., 7x, 7y) will be positioned in a corresponding position. Above the selector (eg, 8x), as shown in Figure 4. Also, on the other hand, in this configuration, the lower end of the knitting tool 7 protrudes into the free space 46, and on the other hand, during the ascent of each selector 8, two of the needle holders 40 are directly adjacent to each other. The lower ends of the knitting tools (e.g., 7x and 7y) are simultaneously docked on the upper end of the associated selector 8x, which is preferably constructed as a support pin 19 as shown in FIG. @ It must be additionally ensured that the support point formed by the top surface of the support stitch 19 between the knitting tools 7x, 7y and the selector 8x is set to be in the absence of webs 42, 44 and others. The free space 46 of the obstacle is very close below. This allows the upper end of the thicker selector 8 to be displaced upwardly beyond the upper end of the second groove 45 for docking in pairs at the lower end of the associated thinner knitting tool (e.g., 7x, 7y) and then Further moving upwards for the needle knitting tool 7 lifts the knitting tools 7 in the same manner as described in Fig. 2 and moves them into the needle path - 16 - 201030200 diameter 29a or knitting path 28a. Without this free space 46, this exemplary embodiment would not be able to place the selector against the lower end of the knitting tool 7 during the ascending motion of the selector 8, as such a selector would hit the first web 42. According to another exemplary embodiment of the invention illustrated in Figure 5, the dual selections described are achieved by first webs 42 (e.g., 42r, 42s) spaced apart by a web, the first webs being The lower end thereof facing the second web 44 extends halfway in the φ axial direction as far as the lower section 40b of the hub 40, thereby bridging the free space 46 shown in Figs. Conversely, the length of the first web (e.g., 421, 42u) positioned between the first webs remains unchanged, such that a free space 46a is formed on the elongated first web (e.g., Between 42r, 42s), and the free space 46a extends from the upper end of the second web 44 to the lower end of the unextended first web (eg, 42t, 42u), as in the free space 46 of FIG. So it is between the two sections 40a, 40b of the hub 40. The free space 46 shown in Figures 3 and 4 is divided in this embodiment into a plurality of laterally substantially free spaces 46a. Each of the free spaces 46a has a width that substantially corresponds to a space between the two second webs 44 or between two elongated first webs (eg, 42r, 42s). space. Further, the upper ends of the selectors 8 are constructed such that they can be embedded in the free space 46a between the lower ends of the extended first webs 42. In general, the self-contained space 46a is sized in the axial direction to be sufficient to allow the selector 8 to perform its maximum stroke, guiding the knitting tool into the knitting position unobstructed. Otherwise, the configurations shown in Figures 3 through 5 are preferably the same as the configurations -17-201030200 shown in Figure 2. This can be clearly seen by the thickness of the stitches 17, 18 of the selector 8 shown in Fig. 2 being twice the thickness of the stitch 7a of the knitting tool 7. Moreover, the different positions of the stitches 7a of the knitting tool 7 show that their selection always occurs in pairs and simultaneously on the directly adjacent knitting tool 7. For example, the two pairs of pins 7ai, 7aj and 7ak, 7al correspond to the selector 8 having the raised pins 17i or 17k, that is, a selector 8 having pins 17i or 17k will have pins 7ai, 7aj and 7ak, respectively. The two knitting tools 7 of 7al are lifted into the knitting path 28a. On the other hand 'selectors 8 with pins 17m or 17〇 (which are lifted by the selection mechanism 10 in a through path) will allow pairs of pins 7am, 7an or 7a, 7ap associated with them. The knitting tool 7 also passes through the non-knit path 35. Finally, a selector 8 having a stitch 8r shows that the two associated knitting tools 7 having the stitches 7ar, 7a are simultaneously moved into the hook path 29a. Figure 6 shows an exemplary embodiment that substantially corresponds to the exemplary embodiment of Figures 3 and 4. However, contrary to the embodiment of Figures 3 and 4, the knitting tool 48 has a first section 48a and a second section 48b that are connected to each other through a transition zone 48c disposed in the free space 46. The first section 48a is disposed within the groove 43 formed by the first web 42 of the hub 40. The transition zone 48c includes sections that are formed by the bend zones of the shank of the knitting tool 48 and that are used to arrange the lower ends 48d of the knitting tool 48 in pairs against each other by the knitting tool 48 from the first web. 42 pre-defined general bond distance (gauge) tl is closer. The reduction in the distance of the lower end 48b allows the selected 201030200 thickness of the second web 44 in the lower section 40b of the hub 40 to be slightly larger and the surface of the knitting tool 48 that is constructed on the lower end 48d to be lifted. There is no risk of not being placed on the upper surface of the selector 8 with its entire surface during the operation. As in the exemplary embodiment of Figures 3 to 5, the knitting tool 48 is arranged to have a spindle pitch t1 which is about half of the spindle pitch t2 of the selector. The exemplary embodiment of Fig. 7 (the same portions as those of Fig. 6 are designated by the same reference numerals) differs from the embodiment of Fig. 6 in that the selector 8 is completely disposed by φ in the groove formed by the second web 44. Inside the slot 45. In order to permit such a design, although the transition zone 48c of the knitting tool 48 is still arranged in the free space 46, the second section 481) of the knitting tool 48 is elongated in the direction of the section 40b of the hub 40, They are caused to protrude into the second groove 45 formed by the second web 44 and abut against the upper end surface of the selector 8 in these grooves. This may provide the benefit that during the entire lifting and pull-down movement of the knitting tool 48, the lower section 48b is directed into the groove 45, as shown by the selector 8z in Figure 7, which has been The state of ascension. 〇 Therefore, if a stronger vibration occurs during the operation of the knitting machine, the lower end 48d of the knitting tool 48 does not accidentally slip off the upper end surface of the selector 8. Another exemplary embodiment of the present invention is shown in FIG. This embodiment differs from the embodiment of Fig. 7 in only two respects. First, each knit tool 48 is only long enough for its lower end region to be disposed all the way in the first groove 43. On the other hand, the portion including the second section 48b and the transition zone 48c in Fig. 7 is constructed as a separate intermediate pusher (auxiliary pusher) 50' having a transition which is bent toward each other in pairs -19 - 201030200 Area 50a. The intermediate pusher 50 has a length sufficient for its upper end 50b to protrude into the first groove 43 and its lower end to protrude into the second groove 45. The width of the second groove is preferably only wider than the width of the end portion 5c. The double sheet is slightly larger. The intermediate sheet 50 is disposed along the schematically shown contact surface 51 or 52 so that one end is in contact with the lower edge of the knitting tool 48 and the other end is in contact with the edge of the selector 8 so that they transmit motion to the knitting. Tool 48 (or vice versa) ° Next, in a manner similar to that of Figure 5, the webs (e.g., 42r, 42s) that are separated by a web are extended into section 40b of the hub 40. In this example, the configuration is selected such that the lower end field of the knitting tool 48 is disposed within the first groove 43 during its entire stroke 'the axial length of its orientation is determined by the unexpanded web (e.g., 421 , 42u), and the selector 8 is disposed in the second groove during its entire stroke. During the different motion strokes, the intermediate pusher 50 is moved to keep the transition zone 50a straight. Within the free space 46a, it does not hit the first web 42 (e.g., 42t, 42u) that is not extended. However, the upper end 50b and the lower end 50c of the intermediate piece 50 are permanently guided into the first groove or the second groove 45. Finally, Figure 8 shows that the transition zone 50a of the pusher selector 50 can also be arranged completely or partially within the second groove 45 because the width of the second groove is sufficiently wide. The intermediate pusher 50 described above can also be provided in the exemplary embodiment shown in Figs. 6 and 7 in a similar manner. Corresponding extensions of each of the first webs (eg, 42r, 42s) may also be extended to push the spurs. The slotted map is provided by 201030200. The exemplary embodiment shown in FIGS. 6 and 7 is provided. In order to achieve a better guiding effect of the lower end region of the knitting tool 48. The exemplary embodiments described above are all based on the principle that the device works with the selector 8, and compared to the knitting tools 7, 48, the selectors have an increased thickness, so that a general selection can be used depending on the pattern. The institution chooses. However, knitting tools having a thickness of about one-half the thickness of the selector are lifted in pairs by the selector 8 (i.e., after each selection step of electromagnetic or the like), each lifted selection The device 8 simultaneously lifts two adjacent knitting tools 7 into a hanging needle or knitting path, for example by means of said cam portion. Thus, in a color or knit pattern, two adjacent stitches in the knit should be identical, i.e., all of the same color or knit architecture. This has the particular advantage of the electromagnetic selection of the selector 8, i.e., the selection process can be doubled and the thickness of the selector 8 can be constructed to be thicker than the thickness of the selector typically used on high denier needle tools. 9 The same advantage can be obtained if the selector 8 is constructed to have the same pitch as the knitting tool 7 or 48 and is disposed in the same groove as the knitting tool. In this example, the selection mechanism can be constructed to simultaneously pivot or move the two selectors 8 adjacent to each other in the hub 40 to a predetermined position in a selection step. This is shown schematically in In Figures 9 and 10, one of the patterning devices according to European Patent EP 03 1 9007 B1 is shown. In this exemplary embodiment, the knitting tool 53 is provided with a receiving mechanism 54 in which the selector 55 is mounted for pivoting. In this example, the selection is implemented via an electromagnetic selection mechanism 56. The selection mechanism has a control element 57 in the form of a striking needle that is movable in the direction of the selectors 55. By the tip end 57a of the striker, a resilient impact is applied to the selector 55, such as by a position in which the selector will pivot from the position shown by the solid line in Fig. 9 to the position shown by the broken line in Fig. 9 and The lower stitch 55a is retracted into the receiving mechanism 54, and the stitch 55b is pivoted out of the receiving mechanism 55. In contrast, according to the invention, the thickness of the control element 57 is the sum of the thicknesses of the two selectors 55 and one of the webs 58 between the two selectors 55 (Fig. 1A). Alternatively, it is sufficient to provide only the thickness of the tip 57a. With these two structures, unlike the previous single selection in each selection step, in the present invention, two knitting tools 53 adjacent to each other in the hub are selected at the same time and guided to a single In the selected path. The frequency at which the control element 57 must be moved is thus half the frequency at which only one selector 55 is pivoted per impact. A similar pattern device can also be constructed using a purely mechanical mechanism. For example, based on the patterning device of the German patent DE 21 64 632 A1, each control element can be manufactured as a pin inserted into a conventional pattern drum, a cam or the like, the width of which is about the needle. Double the size of two adjacent knitting tools in the seat. In this example, the patterning device can also select two knitting tools in each selection step by using a selector having a fineness corresponding to the fineness of the knitting tool and a control element associated therewith having a higher denier. The invention is not limited to the exemplary embodiments of the circular knitting machine and hub described, and these embodiments can be modified in various ways. This also applies to the number of genuine weaving tools that can be selected for each selection step in -22- 201030200. Contrary to the dual selection described above, more than two, such as three or four, knitting tools can be selected simultaneously in each selection step and guided into the same path, such as in a knitting path. Therefore, it is apparent that the present invention can be easily applied to a high-density knitting machine, particularly a knitting machine having a fineness higher than E40. Further, the present invention is not limited to the described selectors, as other selectors and selection elements may be used instead. It is also possible to completely dispense with the selector and φ to allow the selection mechanism and the selection element to act directly on the knitting tool. In addition to this, 'obviously' the selection of knitting tools according to the invention can also be applied to long-haired (p)ush and/or high-pile, knitting machines and flat loom. The drawings are manufactured and the invention is particularly advantageous for implementation on a circular knitting machine in which the needle hub can be constructed in the form of a dial. Furthermore, other selection mechanisms or pattern devices can be used. In principle, the selection mechanism can be constructed in any desired manner and using mechanical mechanisms, purely electronic mechanisms, such as the use of bending elements, pneumatic or electromagnetic mechanisms to implement the selection of φ selectors or control elements. Finally, it should be understood that different features may be applied in a combination of features different from those described and illustrated. [Simplified Schematic Description] Further advantageous features of the present invention can be readily seen from the scope of the patent application of the subsidiary. Out.
