1-needle, Double Chainstitch Machine
The machine comes with a silicon oil lubricating unit, thread spreading mechanism and thread trimming mechanism which trims the thread without fail, thereby consistently ensuring beautifully-finished seams for light- to medium-weight materials.
Product features
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.
Basic performance
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.
