Question 49 (Textile Technology & Fibre Science)

[Show Answer]

Given:
Dwell period of the shedding cam=Crank shaft rotation/3
As we know crank shaft rotation is 180 degree
i.e. Dwell period of the shedding cam( $\Theta$ )=180/3
=60^o
$\Theta$ ₁=60^o , $\Theta$ ₂= 60^o

Sum of two dwell periods( $\Theta$ ) = $\Theta$ ₁+ $\Theta$ ₂

=60^o+60^o

$\Theta$ =120^o (Answer)
