The problem is increased because the filling moves into a field of declining air velocity and thus behaves as if it is propelled from behind; the front moves slower than the rear and the yarn buckles.
由于纬纱进入了一个流速下降的场中,使得问题更加严重,此时相当于气流从后面推动纬纱,纬纱前端的速度低于后部的速度。
The front moves slower than the rear and the yarn buckles. The result is that usually the warp shed must be larger than that for a shuttle loom.
纬纱前端的速度低于后部的速度,纬纱会弯曲,这就要求喷气织机的梭口应大于有梭织机的梭口。
In accordance with these problems, the writer designed out up an groove leading air-current in the front top roller, in the result, the formed yarn strength increases obviously.
针对以上问题,作者设计了前皮辊导流槽,结果使成纱强力明显提高。
