Abstract
A thick fabric of poor surface smoothness, such as a fabric for wet suit, can be fed reliably, smoothly and uniformly to perform sewing of excellent finish, without requiring any oil application to the fabric surface before sewing, by arranging a presser foot body, a small presser foot and a roller as follows. The presser foot body is fixedly supported to a lower end portion of a presser bar supported to a sewing arm part so that it is free to move vertically and reciprocally. The small presser foot resiliently pressing the fabric to the upper surface side of a throat plate is disposed on the downstream side than a needle location hole of the presser foot body in the sewing direction. The roller is disposed on the upstream side than the needle location hole in the sewing direction and is rotatable such that its contact portion with the fabric is successively changed with the fabric feed.
