The aim of this project is to designed and fabricate a machine that will automatically and simultaneously seal and cut sheets of polyphone into a required from. The machine is designed to compete to some extent with international standard. The project is also necessary because it is a test of practical knowledge of student. It also help to prepare student to face the practical problem that they may meet in the field. It is also expected that through such projects student will get more acquainted with material identification and selection. It help in building more knowledge in student about machine development.

When this types of project is improved upon it will contribute much in helping our nations over dependence on foreign countries for provision of goods and machine.
