| Abstract | ||||
| In this work the tension in weft yarns for shuttle looms was measured by with drawing the yarn from pirn in the shuttle (stationary shuttle). The value of weft tension was measured under the effect of the following parameters: - Conicity angle of winds for pirn. - Withdrawal speed of weit yarn. - Linear density of weft yarn. The level of weft tension from the beginning of unwinding up to the end can be reduced by varying the conicity angle of winds and weft withdrawing speed. It was found that small conicity angle of winds is not suitable since the tension level is high compared with large conicity angle of windes, also it is not suitable to increase the speed of withdrawal above 700 m/min. | ||||
