Experiment name: 
Study of Button attaching machine and production of sample.

Introduction: 

There are many types of sewing machine. Some are used for special purposes such as bar tack machine, button hole making machine etc. This type of machines works in a cycle and so these are called simple automatic machine. Here we study on such a type of machine that is button attaching machine.

Objectives: 1.To know about the machine parts.
2.To know about the thread path.

Description: There are different types of button attaching m/c and different types of clamps are needed for different types and sizes of buttons. Especially there may two or three holes in the button. Again button of three holes may be attached by parallel or cross sewing. Buttons may be of different types specially there may be shank below the button or during sewing shank may be made by thread. For sewing button lock stitch, chain stitch or hand stitch machine may be used. When using chain stitch the sewing looks neat below the button but the safety of stitch is low that is the button may be fall out opening the sewing. This will not happen when used lock stitch but it is not as neat as chain stitch. In automatic machine by a hopper and pipe button is fed in button clamp in auto system and button is positioned. Moreover a predetermined number buttons can be attached in a cycle in a predetermined distant in a dress.

Conclusion: This type of machine can not be used for normal purpose. But for making a complete garment their importance can not be denied. Special care and sufficient knowledge is necessary for proper working. Otherwise faulty sewing may be done. I would like to give special thanks to our teacher. I am also grateful to our instructors. I think this will be very helpful in my future life.
