Juki DDL-9000BSS Direct-drive, High-speed, 1-needle, Lockstitch Machine with Automatic Thread Trimmer.
JUKI has developed a new high-long arm machine head one size larger than the head for The conventional lockstitch machine. With its wider area under the arm, the machine permits easy handling of the sewing material for improved operability. In the machine's newly introduced direct-drive system, a compact AC servomotor is directly connected to the main shaft. This motor demonstrates quick start-up, upgraded stop accuracy, and excellent responsiveness.
 
This 1-needle lockstitch machine is JUKI's highly advanced model provided with a thread trimmer which operates at the highest speed of its kind, a mechanism which promises silent operation and various technical features which promise power saving. JUKI pursues the highest seam quality, highest productivity, easiest operation and smallest power consumption at all times. Now, JUKI has launched its cutting-edge 1-needle lockstitch machine which is a successor model of the DDL-9000 and DDL-9000A. The DDL-9000B is the top of the line lockstitch machine developed by JUKI, a company which always strives toward the achievement of genuine quality.
 
The line-up of the DDL-9000B series in terms of lubricating method of the machine head consists of: S: Minute-quantity lubrication, M: Semi-dry head type and D: Fully-dry head type. All of the three machine head types are friendly to the environment since they prevent oil stains and minimize the quantity of stain remover used. Select one of the three different machine heads according to your sewing applications.
 
- The latest compact-size servomotor has been adopted. The DDL-9000B has adopted the latest compact-size servomotor as its driving source. This latest compact-size servomotor is an energy-saving, highly efficient motor which is able to run under a high torque and has a broader range of speed. In addition, the servomotor is installed with a direct-drive system to transmit the motor power directly to the sewing machine, thereby achieving improved power-consumption saving, quicker response, quicker startup, increased accuracy of the stop position and stronger material penetrating force of the needle.
- The new model control box, which energy-saving mode is provided. The new model control box SC-920, which consists of an energy-saving mode, has been developed. This control box is the first one which provides an energy-saving mode for the sewing machine. The power consumption during standby, when the motor is at rest, is reduced by approximately 20%. In addition, abundantly incorporated state-of-the-art energy-saving features such as a compact-in-size solenoid for the auto-lifter (optional) allow the DDL-9000B to reduce power consumption, to increase productivity and to be friendly to the environment.
- The needle bar mechanism is finished with a special surface treatment (DLC, Diamond Like Carbon Coating) and uses JUKI's unique special grease for lubrication. Grease-filled bearings have been adopted for the sections requiring bearings. The frame mechanism of the sewing machine demonstrates superb durability even with no oil. Oil stains on the material being sewn are reduced. As a result the frequency of stain removal work or re-sewing work is dramatically reduced, thereby improving the finished quality of the product
- The DDL-9000B trims thread at least two times faster than the conventional thread trimmer, thanks to the improved thread-trimmer driving mechanism. This improves the responsiveness of the sewing machine during changeovers between sewing and thread trimming operations. The length of time elapsing from thread trimming at the end of sewing to the start of a subsequent operation can be shortened, thereby improving operator rhythm.
- The switch is mounted above the one-touch type reverse feed switch. With this handy switch, the operator is able use various functions with ease. The switch is helpful especially in standing work. With th
- The auto-lifter is a device for automatically lifting the presser foot (by the knee). It is helpful also in standing work.
- The micro-lifter works to prevent damage to the material or a slip between two plies when sewing a shaggy or elastic material. The micro-lifter is finely adjustable in its height without using a tool.
- The non-rotary bobbin eliminates irregular stitches which have a tendency to occur at some sewing speeds and bobbin-thread tension fluctuations which have a tendency to occur according to the bobbin thread remaining on the hook. Since the bobbin thread is fed without rotating the bobbin, the bobbin never idles.
- The hook is used with the lubrication stopped, thereby preventing oil stains. The non-lubricated hook has a lace made of special plastic.
- As compared with the regular hook, the lubricated hook C has a structure which has been designed giving a higher priority to the high-speed sewing capability. The hook has a shaper blade point which is provided with a needle guard.
