Coverlock machines

Coverlocker

— devices that combine an overlocker and a coverstitch machine in one case. For more information about each of these varieties, see the relevant paragraph. Here we note that the coverlocker is a universal tool for processing edges: it can overcast them, cut off the excess fabric and hem the folded edge with a cover stitch. In addition, many modern coverlocker are also capable of seaming materials (mainly with a double-thread chain stitch).
