Computer-controlled, Dry-head, High-speed, Single-thread, Chainstitch Button Sewing Machine

With its button feeder, the machine increases productivity.
The machine flexibly responds to the small-lot production systems applied for various kinds of products. The outstanding ease in its operation promises higher productivity.

Product features

  • The machine dramatically improves productivity

    With its increased button-feeding speed and high-speed machine head capable of a maximum sewing speed of 1,800rpm the machine dramatically increases productivity. Furthermore, its button-discharging machanism and easy-to-adjust functions make it easy to change the setup when changing the buttons to be sewn, thereby eliminating wasted time at start-up.

  • Three different operation modes are available, enabling this machine to be employed by a small-lot production system

    The three different operation modes available are the automatic button feeding mode in which the machine continuously feeds the buttons in the feeder bowl, the non-feed mode in which the operator manually places the buttons in the sewing position one by one, and the small-lot sewing mode in which the operator sets the buttons in place for one garment (five or six buttons) in advance, upon which the buttons are automatically and continuously fed to the sewing position. As a result the machine can employed by a small-lot production system by selecting the appropriate operation mode.

  • The machine ensures remarkable ease in operation

    The machine is provided with a wider sewing area to facilitate garment setting, and allows the operator to check the remaining quantity of buttons while remaining seated, thereby enhancing ease of  operation. Furthermore, the machine allows the operator to continuously sew buttons with pedal depressed, thereby helping reduce the operator's fatigue.

Basic performance

  • Excellent seam quality and improved flexibility

    It comes with direct-drive electronic feed driven by a compact AC servomotor to guarantee excellent seam quality and dramatically improve flexibility and maintainability.

  • The machine is able to independently sew various stitching shapes such as U-shaped stitching, X-shaped stitching and Z-shaped stitching

    • The machine has 55 different stitching patterns as standard. In addition to the sewing shapes, the buttonhole intervals and number of stitches can also be changed on the operation panel. The machine completely supports many different button specifications to increase its range of applicability, reduce costs associated with changes in specifications, and save the operator from having to adapt the machine to different specifications.
    • Custom patterns can be created on the PGM-20 and then used on the sewing machine.

  • Shorter lengths of thread remain after thread trimming

    The machine performs thread trimming at the optimal position by correcting the button position with respect to the needle entry of the last stitch. This shortens the thread remaining on the material after thread trimming to approx. 3.5 mm.

  • The dry-head eliminates oil stains

    The machine head is a non-lubricating type. With this type, the operator never has to add oil, and staining of the sewing product with oil is an impossibility.

  • The machine sews buttons with beautifully finished seams

    • The machine adopts a stitching pattern with the tying stitch only at the final stitch. This ideal stitching pattern optimizes single thread chainstitching to produce beautiful seams on the wrong side of the material, thereby guaranteeing excellent seam quality.
    • Moreovers, since the machine uses significantly fewer mechanical parts, troubles caused by excessive play in the feed such as needle breakage and button breakage occur for less often.
  • The machine is equipped as standard with thread-fray-prevention function

    • The machine comes as standard with the solenoid-operated, thread-tension-changeover “thread-fray-prevention function.” Since the machine is designed to use a long needle (TQ×7), the “thread-fray-prevention function” can be used for sewing shank buttons.
    • The “thread-fray-prevention mechanism” can be rendered ON or OFF as required by setting the solenoid drive ON or OFF.

  • The machine offers outstanding productivity

    The machine runs at a maximum sewing speed of 1,800 rpm and comes with a direct-drive system supported by a compact AC servomotor that offers excellent stopping accuracy and responsiveness. Working in combination, these features shorten the machine time by 10 % or more compared with our conventional machine.
    Needless to say, the single-thread, chainstitch, button sewing machine does not need bobbin thread changing.

  • Excellent maintainability and operability

    • Thanks to the elimination of the mechanical structures such as the stop-motion mechanism and feed cam, the machine operates with less vibration and noise and requires no maintenance.
    • The foot pedal can be operated with reduced pressure from the operator's foot. This helps reduce operator fatigue by allowing the operator to operate the machine more rhythmically.
