Question

In a projectile weaving machine, the projectile travels through the shed at an average speed of 24 m/s taking \( \frac{2}{3} \) of the loom cycle. If the efficiency of the weaving machine is 90%, the weft insertion rate (m/min) is:

Hint:

For calculating weft insertion rate, consider both the speed of the projectile and the efficiency of the weaving machine to get the effective weft insertion.

Answer 1

1. Total loom cycle time (\( T_{\text{cycle}} \)):
\( T_{\text{cycle}} = \frac{3L}{2v} \)
2. Weft insertion rate (WIR):
WIR = \( \frac{L}{T_{\text{cycle}}} \times 60 \times \eta = \frac{2v}{3} \times 60 \times 0.9 = 864 \, \text{m/min} \)
Final Answer: 864
