Automatic 1-needle Belt-Loop Attaching Machine

AB-1351 is the world's first belt-loop attaching machine with the ability to solely sew seven different belt-loop sewing patterns!
JUKI's unique flexible automatic belt-loop attaching machine!

Product features

  • Belt-loop folding mechanism which supports various belt-loop specifications (patent pending)

    This is the world's first automatic belt-loop attaching machine which can be used for seven different belt-loop attaching processes. The main mechanisms have been computerized to develop a belt-loop attaching machine which sews diversified belt-loop styles.

  • Improved productivity

    This machine not only reduces the time required for the belt-loop attaching process, but also achieves labor-saving, such as the elimination of the previous process (belt-loop cutting). Productivity can be dramatically increased when one operator attends to two AB-1351 units.
    Productivity is dramatically increased when the operator attends to two AB-1351 units.
    Two AB-1351 units can be operated by only one operator. In the case where two AB-1351 units are placed, as shown in the picture, the operator is able to operate them alternately to attach belt-loops on two different garment bodies, thereby substantially increasing productivity.

Basic performance

  • Quality production without relying on operator skill

    This machine allows an inexperienced operator to sew various types of belt-loops. The operator only needs to place a garment body on the machine and press the switch. The belt-loop sewing shape and sewing size can be easily changed through the operation panel.

    Belt-loop size adjustment and belt-loop specification changing have been digitalized

    The AB-1351 has adopted, as its operation panel, the IP-420 which has a large color liquid crystal touch panel. With this operation panel, the operator can change the belt-loop shape or sewing pattern, set the belt-loop sewing position and carry out cycle sewing. When the belt-loop width is changed, the bartacking width can be automatically changed according to the percentage of change of the belt-loop width. Digitalization helps substantially reduce the time required for sewing data adjustment.

  • Quality improvement

    JUKI's unique belt-loop feeding/folding mechanism helps achieve beautifully-attached consistent-quality belt-loops with constant sewing dimensions (amount of slack).

    JUKI's unique belt-loop feeder unit

    The belt-loop feeder unit incorporates JUKI's unique twin system. It is able to feed belt-loops with consistency even when a soft and elastic material is used. The belt-loop feeder unit is arranged in front of the main body of the sewing machine. This allows the operator to insert belt-loops from the front of the machine. In addition, the operator can visually check the belt-loop state whenever necessary, even during sewing.

  • The machine can be used for two different sewing styles by installing / removing the sub-tables

    The sewing machine can be used for two different sewing styles, i.e., for sewing belt-loops on waistbands (flat sewing) and for sewing belt-loops on garment bodies (tubular sewing), by installing / removing the sub-tables (auxiliary table and waistband table). The position of the start switch can also be changed. (The machine is provided with sub-tables as standard accessories.)
