Abstract-The raw jute plays an important role for the socio-economic and ecological condition of India from long time since when the people uses these products for their different purpose. It is bio-degradable and recyclable in nature having unique characteristic of absorbing atmospheric CO2 and releasing O2 gas to atmosphere, this will helps a lot for the purification polluted air. The bales obtained from raw jute were usually transported to the mills and warehouse for stacked used for production purposes. Considering all the drawback of the existing machine, compact size, manually operated bale press machine has been designed and developed at CSIR-CMERI. The basic requirement of stress analysis and effort has been calculated with reference to the capacity of the male adult worker. The required effort to rotate the handle is 190N, and as per design calculation the value obtained is 215.82N as the force applied workers. The equivalent stress and maximum shear stress was calculated based on the applied efforts it comes to around 114MP and 65 MP respectively also the value of analysis of von-Mises stress comes to 428MPa. Hence it is found that from the calculated values obtained the lead screw and the body structure is found to be under safe condition.
