Mainly over edge machines are overlock machines. In this type of sewing machines there are one or two needles and edge-trimming knife is at the front of needle. To make over lock stitch 2-5 threads are used. Usually SPM of over lock machine is 6500. But SPM of 8500 machines are also found. In this machine there also stretching (stretching max 1: 0.6) and gathering (gathering max 1: 4) systems during feeding cloth. Stitch is done up to maximum 4 mm length and stitch length may also be changed by push button. This type of machines can be used for sewing for both woven and knitted cloths.

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.
