Question 49 (Textile Technology & Fibre Science)
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 __120__.
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()=180/3
1=60o , 2= 60o
Sum of two dwell periods() =1+2
