1-needle, Double Chainstitch, Bottom and Variable Top-feed Machine

An easy-to-operate, high-precision presser foot, feed dog and thread draw-out mechanism have been developed for this sewing machine so that any operator can finish seams of the highest quality.
The machine flexibly adapts to a wider range of light- to heavy-weight materials, process changes, and sewing specifications, including partial shirring.

Product features

  • The machine incorporates many functions and places a great deal of importance on higher product quality

    The machine comes with many different functions to prevent uneven material feed and puckering for higher-quality seams.
    The machine is adaptable to a wider variety of light-to heavy-weight materials and takes full advantage of top-feed mechanism.
    This enables unskilled operators to finish seams of consistent quality.

  • The top-feed dog has been designed so that the operator can smoothly place the material to be sewn on it
    Furthermore, the gauge can be easily replaced and stitch adjustment can be performed without difficulty

    The machine comes with a forced lifting mechanism for the top-feed dog. This enables the operator to place the material to be sewn on the top-feed dog more smoothly. The machine incorporates its exclusive chain-off thread presser pedal foot, which improves seam quality and ease of operation.
    The exclusive gauge comes in five different types, and the gauges can be replaced in a simple procedure. This facilitates the required adjustment when changing the needle count.

  • The machine is also capable of performing partial shirring

    The machine works effectively for processes which require partial shirring as long as the partial shirring device (PH-3) is used in combination with the partial shirring dial.
    The partial shirring device comes in two different types, the kneepad drive type and the pedal drive type.

Basic performance

  • The machine is provided with mechanisms to enable upgraded sewing

    The machine comes with a thread spreading mechanism and an adjustable needle guard to prevent stitch skipping. The thread clamp mechanism, tension release mechanism and needle thread draw-out mechanism enable the machine to leave thread of a uniform length after thread trimming, and prevent slip-off of the needle thread. All of these mechanisms contribute to upgraded sewing.

  • Safety stitching or reverse feed stitching with a simple lever operation

    Safety stitching (condensation stitching) the perfect method of preventing loose stitches, or reverse feed stitching (back-tacking) can be alternated through the simple adjustment of the stopper of the reverse feed lever. Either sewing method can be used.

  • Beautifully finished seams

    Provided with a sliding presser foot and a silicone oil lubricating unit as standard, stitch skipping and puckering are prevented. Furthermore, the silicone oil lubricating unit prevents the needle from overheating, and allows foundation yarn or synthetic thread to be used without breakage during sewing. These features assure beautifully finished seams with consistency for light- to medium-weight materials.
