您要查找的是不是：
- When the back roller does not rotate, the tension in the horizontal part of the warp sheet will increase as the angle of the warp sheet round the back roller increases as the warp weaves down. 如果后梁不转动,随着织造的进行(织轴逐渐变小),经纱对后梁的包围角会增大,处于水平位置的经纱片的张力会增加。
- The yarn from the weaver's beam passes round the back rest and comes forward through the drop wires of the warp stop motion to the heald, which are responsible for separating the warp sheet for the purpose of shed formation. 从织轴上退绕下来的纱线绕过后梁,向前穿过经停机构的停经片及综丝,综丝的作用是将经纱片分开形成梭口。
- Since there is usually some slippage between the warp sheet and the surface of the back roller, the wavelength of the fault produced in the fabric is likely to be rather greater than the circumference of the back roller. 这种现象只有在后梁能灵活自如地转动时才消失。通常由于后梁表面与经纱片之间会有一定的相对滑动,织物中的疵点片段长度有可能大于后梁的周长。
- This is to avoid beat - up with the shuttle trapped between the two warp sheets or having a very weak pick the next time around. 这样可以避免梭子依然还在梭口当中时进行打纬,也可避免在下次投梭时投梭力不足。
- It then passes through the reed, which holds the threads at uniform spacing and is also responsible for beating - up the weft thread that has been left in the triangular warp shed formed by the two warp sheets and the reed. 然后经纱穿过钢筋。钢筘使经纱均匀分布,同时也负责推动留在三角形梭口中的纬纱以完成打纬,梭口是同两层经纱和钢筘构成的。
- For these reasons, a series of guides are used to constrain the projectile as it passes across the loom. To make this possible,the projectile guides must protrude through the warp sheets. 基于上述原因,使用了一系列的导梭片,在片梭穿越梭口时,对其进行控制。为达此目的,导梭片必须穿过下层经纱(进入梭口中)。
