Abstract
A fabric guide device for a sewing machine has an upper plate and a middle plate, and is disposed at the fabric feed side of the presser foot of the sewing machine. The upper plate is disposed on the sewing machine bed in a state of keeping a certain clearance from the sewing machine bed, and its fabric feed side portion is warped upward. The middle plate is disposed beneath said warped portion of the upper plate, and is free to project and retreat from and into the sewing machine bed. The middle plate has upper and lower surfaces for guiding the upper and lower bodies. When sewing said bodies together, first the middle plate projects from the sewing machine bed to insert between the bodies. Then the bodies are pulled forward, and the over-edge chain stitching portions are engaged with the middle plate to be tilted to the fabric feed side. In the tilted state, the bodies are further pulled to the front side, and the over-edge chain stitching portions are positioned beneath the presser foot, and then the presser foot is lowered to start sewing operation.
