The double roller gin is consisting of two counter rotating leather rollers, oscillating beater, fixed knives and chain and sprocket arrangement. This double roller gin has side frames, which are made of Cr alloy plates instead of casted frames. An improved power transmission system consisting of triplex chain and sprocket mechanism for rotating the rollers and oscillating the beater in double roller gin. Right had side roller (roller no.1) is rotated in anticlockwise direction by a triplex sprocket and chain arrangement. Idler sprockets are provided to triplex chain to adjust the appropriate chain tension. Desired rpm of roller is achieved by this mechanism. Rpm of roller can be changed with change of sprocket attached to roller shaft. The left hand side roller (roller no.2) is rotated in opposite direction (i.e. in clockwise direction) to that of right hand side roller (roller no.1) with the help of idler sprockets by the same triplex chain. Precise pressure of rollers on the fixed knives is applied with the help of push-pull and locking mechanism instead of dead weights. This machine r3equires 2 sq. meter space whereas conventional machine requires 4 sq. meter space,. Therefore there is a saving of space. Drawing: 2 Sheets Total Pages: 13 Fig. Nil
