Opening (woven fabric) - Kaikou

…
【principle】
(1) A large number of threads (called warp threads) arranged horizontally are moved up and down alternately or in a random order to separate them into two groups of threads, (2) another thread (called weft thread) is passed between them at right angles, and (3) this weft thread is advanced so that it is lined up with the previously inserted weft thread at a specified interval. (1) is called the opening, (2) is weft insertion, and (3) is weft beating. By repeating this series of movements, a woven fabric with a specified structure can be produced (Figure 1). A loom that performs these operations using hands and feet is called a hand loom or hand loom, and one that is powered is called a power loom (Figures 2-a and 2-b).

【原理】
　(1)水平方向に並べられた多数の糸(経糸（たていと）という)を交互に，あるいは適当な順序で上と下とに移動させて2群の糸に分け，(2)その間に別の糸(緯糸（よこいと）という)を直角方向に通し，(3)この緯糸を前に挿入した緯糸と所定の間隔で並ぶように前進させる。(1)を開口，(2)を緯入れ，(3)を緯打ちといい，この一連の運動を繰り返すことにより，所定の組織をもった織物を作ることができる(図1)。これらの操作を手足で行う織機を手織機（ておりき）または手機（てばた）といい，動力で運転するものを力織機という(図2‐a，図2‐b)。…
