Abstract
Disclosed is a zigzag sewing machine in which a trimming device for trimming the marginal edge of a work fabric is removably disposed at a predetermined position on a machine bed so that the trimming device is driven in relation to the operation of the sewing machine. The zigzag sewing machine comprises a switching device for changing the field position of the needle oscillation and an operated member for actuating the switching device in relation to the disposition of the trimming device at the predetermined position. In this zigzag sewing machine, while overedge stitching is performed by using the trimming device, the field position of the needle oscillation is set so that zigzag stitches having a desired stitch width are always placed along and over the marginal edge of the work fabric trimmed by the trimming device.
