The standard model of JUKI 1-needle lockstitch machines with an automatic thread trimmer.
The DDL-8700-7 is provided with the "new model control box" and the "new model compact servomotor," thereby substantially saving energy.
The new model control box SC-920C has been newly developed. The control box is resistant to voltage fluctuations, noise, and vibration. The new model control box is provided with an energy-saving mode for the first time in a control box for sewing machines. It reduces power consumption during standby time when the motor is not rotating by approximately 25% (in comparison with the SC-910N). In addition, the current DDL-8700-7 is lavished with the latest energy-saving technologies, including the adoption of the latest compact servomotor M92, to be more friendly to the environment, as well as to provide the power reducing effect and to increase productivity.
The production support function actually consists of three different functions (six different modes), which are the output control function, operation measuring function, and bobbin counter function.
Target No. of products display mode/Target-actual result difference display mode - Under the target No. of products display mode, the target number of products and the actual number of products produced according to the work hours are displayed. - In the under target-actual result difference display mode, the difference between the target number of products and the actual number of products produced is displayed.
Sewing machine availability display mode/Pitch time display mode/Average speed of stitch display mode - Under the sewing machine availability display mode, the average sewing machine availability in the previous cycle and the current cycle are displayed. - Under the pitch time display mode, the average process machining time in the previous cycle and the current cycle is displayed. - Under the average speed of stitch display mode, the accumulated speed of stitch in the previous cycle and the current cycle is displayed.
Bobbin counter display mode. The operator is notified that the bobbin needs to be replaced before the bobbin thread runs out.
The DDL-8700-7 machine comes with a thread trimming mechanism that performs speedy and reliable thread trimming to achieve highly efficient sewing work.
By thoroughly investigating and modifying the sewing mechanisms in order to achieve low-tension sewing, the machine flexibly responds to various kinds of materials and produces beautiful seams of consistent quality.
The optimum-balance and highly rigid machine head were created using the latest 3D-CAD design technology. Thanks to its low vibration and low noise feature, the machine head provides the operator with a comfortable work environment. In addition, the distance from the machine arm to the needle on the front of the machine head is sufficiently wide to allow easy handling of the sewing material. The machine inherits the desirable features, such as high-speed stitching performance 5,000sti/min, extreme stitching performance, ease of operation, and reliability, from the highly evaluated previous JUKI lockstitch machines
The DDL-8700-7 machine is provided as standard with extra attachment mounting seats for attachment of new auxiliary parts in the future. The extremely high durability of the seats ensures an extended service with frequent replacement of attachments.
