Features of overlock machines
- Cutting device: Overlock machines are equipped with a cutting device (knife) that cuts fabric edges (excess margin) while stitching.
- Adjustable seam width: Width of a seam can be set based on seam width needed in a design.
- Stitch density (SPI): Stitch density can be changed in these machines
- Safety stitch can be sewn by overlock sewing machines.
- Thread consumption by overlocker – thread consumption in overlock machines is higher than single needle lock stitch machines.
- Machine bed – Normally machines come with a raised bed – machine bed is raised than the tabletop. But in need, you can use sunken bed where the tabletop is kept in the same height of the overlock machine bed.
Usage of overlock machines:
Overlock machines are available in 3 threads, 4 threads and 5 threads overedge sewing.
This machine is used for serging garment panels (e.g. trouser panels) and for overedge stitches (e.g. side seam of T-shirts). Overlock machines give a clean finish to seam edges.
For example, in a T-shirt making overlock machine is used for operations like
- Attaching sleeve,
- Joining side seam and underarm, and
- Attaching neck rib to the neck.
