Description: 
This machine may be of flat bed or cylinder bed type. In our lab 21, 22 nos. machines are flat bed and 32 no. machine is cylinder bed type. Flat bed is used for sewing body cloth and cylinder bed is used for sleeve cloth. In this machine 4 needles may also be used and sewing may be done using from 4 to 9 threads. Sewing with flat lock machine the most quantity thread is needed. For example for sewing 1 inch cloth up to 32 inches thread is needed. The SPM of this type of machine is usually 6000 and 8-16 stitches may be done per inch. It is a very expensive machine and is used for mainly sewing knitted goods but also used for making woven cloth.

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.
