Description
The placement of the feed mechanism has been charged to decrease the feed amount when the needle enters the material, thus preventing the needle from bending. The bobbin thread is clamped without fail, thereby producing consistent thread loops.The looper tucks the needle thread without fail, thereby finishing uniform seams.
The number of teeth of the feed dog has been increased so that it can easily catch overlapping material. The shape of the presser foot has been modified to prevent single-sided contact with the overlapped part. The movable needle guard (rear) is provided with a vertical adjusting mechanism. These features contribute to smoother feed of heavy-weight materials, thereby preventing stitch skipping.
