          沖擊式折頁原理
          Impact folding principle
          借助于縱折三角板,沿紙張的縱向獲得折,活動折刀伸出折頁滾筒沖折紙張,將紙張推至兩個連續旋轉的折輥4之間,將所折頁帖壓實,并傳送到收帖花滾筒。按此原理進行折頁的折頁裝置稱為沖擊式折頁機。沖擊式折頁機結構簡單,適于高速印刷,但折頁精度稍低。
          With the help of the longitudinal folding triangle, the folding is obtained along the longitudinal direction of the paper, the movable folding knife extends out of the folding roller to fold the paper, pushes the paper between two continuously rotating folding rollers 4, compacts the folded paper and transmits it to the collection roller. According to this principle, the folding device for folding is called impact folding machine. The impact folding machine has simple structure and is suitable for high-speed printing, but the folding accuracy is slightly low.
          滾折式折頁原理
          Roll folding principle
          已經斷切待折的紙張在折頁滾筒2和輸出滾筒1上,由挑針4挑住轉動,在對滾滾筒的連心線上,彈性折刀5將紙張3入滾筒2的空檔中,夾板6和7沿折線將其夾緊,并由滾筒2帶走,折刀從折縫中退出。利用一個滾筒的折刀和另一個滾筒的夾板在相對滾動中完成折頁的裝置稱為滾筒式折頁機。
          The paper that has been cut and to be folded is held and rotated by the pick-up pin 4 on the folding drum 2 and the output drum 1. On the connecting line of the opposite rolling drum, the elastic folding knife 5 puts the paper 3 into the neutral of the drum 2, the clamping plates 6 and 7 clamp it along the folding line and take it away by the drum 2, and the folding knife exits from the folding seam. The device that uses the folding knife of one drum and the splint of another drum to complete folding in relative rolling is called drum folding machine.
          滾動式折頁機折頁精度較高,速度快,一般用在卷筒紙書刊輪轉印刷機上。根據所完成的折頁次數,折帖的類型,采用不同數目的折頁滾筒和折頁方案。

          The rolling folding machine has high folding accuracy and high speed. It is generally used in the rotary printing machine of Web books and periodicals. According to the number of completed folding and the type of folding, different number of folding rollers and folding schemes are adopted.
          刀式折頁原理
          Knife folding principle
          刀式折頁是采用折刀1將紙張4壓入兩個相對旋轉的折頁輥2之間,再由折頁輥送出,完成一次折頁過程。完成折頁后的紙張被傳送帶帶走,進入第二折,第三折。
          Knife folding uses a folding knife 1 to press the paper 4 between two relatively rotating folding rollers 2, and then sent out by the folding roller to complete a folding process. The folded paper is taken away by the conveyor belt and enters the second and third folds.
          刀式折頁具有較高的精度,書帖折縫壓的實,由于折刀的運動慣性,折頁速度較慢。
          Knife folding has high precision, and the book folding seam is pressed. Due to the motion inertia of the folding knife, the folding speed is slow.
          柵欄式折頁原理
          Principle of fence folding
          由輸頁裝置送出的印張4,經過兩個旋轉的折頁輥2,輸送到折頁柵欄里,撞到柵欄檔板5時,印張便被迫彎曲成對半形折入折頁輥3中間,完成折折頁,然后將折過一折的書帖到下一個折頁柵欄里,用同樣的方法進行第二、第三折。后被送到收紙臺,完成一個書貼的折疊工作。
          The printing sheet 4 sent by the page conveying device is transported to the folding fence through two rotating folding rollers 2. When it hits the fence baffle 5, the printing sheet is forced to bend into half shape and fold into the middle of the folding roller 3 to complete the folding, and then the folded book is pasted into the next folding fence, and the second and third folding are carried out in the same way. Then it is sent to the paper receiving table to complete the folding of a Book sticker.
          沖擊式、滾折式、刀式以及柵欄式這四種是常見的折頁方式,每一種都有各自的特點。實踐固然重要,但是理論知識是實踐的提和基礎,二者不可荒廢其一。
          Impact folding, roll folding, knife folding and fence folding are four common folding methods, each of which has its own characteristics. Practice is important, but theoretical knowledge is the basis of practice. One of the two should not be abandoned.
