Question

For a shuttle loom, producing plain woven fabric, if each of the dwell periods of the shedding cam corresponds to one-third of crank shaft rotation, the sum of the two dwell periods of the cam (in degree) is \(\underline{\hspace{2cm}}\).

Hint:

For shuttle looms, the dwell periods are typically a fraction of a complete rotation, often calculated based on the mechanical setup.

Answer 1

Correct Answer: 120

If each of the dwell periods corresponds to one-third of a crankshaft rotation, then each dwell period is: \[ \text{Dwell period} = \frac{1}{3} \times 360^\circ = 120^\circ. \] Thus, the sum of the two dwell periods is: \[ \text{Total dwell period} = 120^\circ + 120^\circ = 240^\circ. \] Thus, the sum of the two dwell periods is \( 120^\circ \).
