These are the pictures of a class project done by Raoul D. Dib and Charbel S. Saleh at the Lebanese University Faculty of Engineering - Roumieh. They manufactured their mechanism from the animation shown in here I am very happy that my efforts inspires young engineering students, and pleased with their contribution to my web site. You can find the technical drawings of Raoul in here.
I would like to thank Raoul El Dib for providing the pictures of his material feed mechanism. If you are looking to build your own mechanism, I recommend you find the dimensions of your feed mechanism with trial and error. You will learn much more with trial and error than imitating Raoul's dimensions.
