Abstract
In this overedge sewing machine, when stitch width is adjusted, an adequate excess thread proportional to the adjusted stitch width is obtained. An overedge stitch can be steadily sewn without excessive stitch tension, even when the stitch width increases. By operating one adjustment member, the position of the lower knife holder and the stitch-support member can be easily adjusted, and the stitch width can thus be easily altered.
