The sewing machine produces soft seams with consistency with a low tension applied to the thread.
Problems which are associated with low-tension sewing such as “double-catching” and “irregular stitches”, as well as factors which affect seam quality such as “thread path”, “thread bending resistance”, “feed locus”, “needle locus” and “timing” have been thoroughly reviewed, thereby successfully producing soft seams. The machine has adopted JUKI’s established genuine hook and thread take-up lever.
- Presser adjustment screw add scale line
Presser adjustment screw attached the scale line at standard. - Screw for the attachment is provided as standard
The machine is provided as standard with a screw which is necessary for attaching the guide device. This facilitates response to various processes. - Bobbin thread winder
The bobbin thread winder is built-in at the top surface of the machine head. The bobbin winder incorporates a thread cutting knife for cutting the thread after the completion of bobbin winding. - Micro-lifter
It works to constantly material or other difficult-to-sew ones,thereby helping effectively reduce material slippage as well as damages made by the presser foot on the material. - The compact-size servomotor*
The LZ-2284A-7 has installed with the compact servomotor which has directly connected to the main shaft.
*Applied only to 00, 0B and models with automatic thread trimmer - Silent and low-vibration operation
The needle rocking cam has been totally reviewed to enable comfortable sewing even during high-speed sewing. - Easy-to-operate adjustment mechanism
For the adjustment of the needle position, needle throwing width and stitch base line, an easy-to-operate lever style has been adopted. In addition, the feed amount and the condensation mechanism for fastening stitches can be easily adjusted since an adjustment dial has been adopted. - The lift of the presser foot has been increased and the LED has been provided as standard
The visible area around the needle entry point has been increased and the LED light has been installed, thereby helping reduce the operator’s fatigue when sewing small parts. The illuminance of the LED light can be adjusted near the needle entry point. 8 9 10
*LED : Applied only to 00, 0B and models with automatic thread trimmer - Automatic reverse feed function
The automatic reverse feed switch can be re-positioned to best match the operator. - Attachment-mounting seat
Installation of an attachment-mounting seat improves operability when replacing the attachment and increases the durability of the machine bed surface.

Maintenance
- The adjustable range of the feed mechanisms has been widened, thereby upgrading the machine’s responsiveness to materials
The feed mechanism has been improved by widening the adjustable range of the height and inclination of the feed dog. The feed locus has been optimized while placing great emphasis on the feed locus at the moment the needle penetrates the material to form a stitch. The weight of the feed mechanism has been reduced by using parts most of which are made of aluminum material. This facilitates sewing of overlapped sections of material that have to be securely held between the presser foot and the feed dog during sewing. - Adjustment for various feed timings
Marker lines engraved on the face plate and the pictorial indication facilitate adjustment of the needle-to-feed timing and the hook timing. - Adjustment of oil quantity in the hook
Oil feeding path of the LZ-2280A Series has been reviewed to enable feeding of consistent quantity of oil.
Equipped with two different functions, the machine is available to handle a wider range of application
LZ-2284A (Standard/3-step Zigzag) and LZ-2287A (3-step Zigzag/Scallop) can perform two stitching patterns by one machine, thereby increasing the machine operation rate.
Standard/3-step Zigzag Stitching Pattern Changeover Function
Switch between the standard zigzag stitching pattern and 3-step zigzag stitching pattern with simple one-touch control 3-step zigzag stitching and scallop stitching can be changed over through fingertip control
The mechanism for changing over the type of stitching between standard zigzag stitching and 3-step zigzag stitching has been well-received in the market. Now, the sewing machine which is able to change over the type of stitching between 3-step zigzag stitching and scallop stitching which are frequently used for sewing girdles has been added to the LZ Series. The operator can easily switch the needle-throwing pattern between the standard and 3-step zigzag stitching patterns using the lever located in the free space under the arm. When changing the sewing product or design, there’s no need to adjust the sewing machine head or machine layout.
High-speed, 1-needle, Lockstitch, Zigzag Stitching Machine
Switch between the 3-step zigzag stitching pattern and scallop stitching pattern with simple one-touch control (The world’s fastest)
3-step zigzag stitching and scallop stitching can be changed over through fingertip control
The mechanism for changing over the type of stitching between standard zigzag stitching and 3-step zigzag stitching has been well-received in the market. Now, the sewing machine which is able to change over the type of stitching between 3-step zigzag stitching and scallop stitching which are frequently used for sewing girdles has been added to the LZ Series.
Options
| Part No | Description | Feature |
| 40135177 | Automatic reverse feed Kit | This device allows a machine without thread trimmer to perform automatic reverse feed function. |
| 225-26578 | Hook with a hard blade point | Prevents the blade point of the hook from wearing out |
| 229-07406 | Presser spring | This is the spring which strongly holds down the material when sewing a heavy weight material. |
| B3129012A00 | Tension spring | Tightly tensed seams can be produced by increasing the tension applied to the needle thread. |
| 40135178 | Auxiiary Thread take-up Kit | Thread breakage and stitch skiping can be prevented by stabilizing the needle thread loops. |
Hook with non-rotational bobbin
The hook with non-rotational bobbin eliminates sewing troubles resulting from bobbin idling. It provides a uniform bobbin thread tension at all times, thereby guaranteeing a consistent stitch formation.
235-23152 Hook
235-22550 Bobbin case (asm.)
235-23004 Bobbin
| Application | Mainly for the standard zigzag stitch: Effectively prevents the material swelling at the sewn part, as well as irregular stitches when sewing lace to slips, camisoles and shorts. |
| Precaution | The quantity of thread to be wound around this bobbin is approximately 60% of that wound around the conventional bobbin. Therefore, this bobbin is not recommended for pattern stitching such as three-point zigzag stitching and scallop stitching, or intape-attaching processes, even if the stitch system is the standard zigzag stitch. |
| Applicable thread | Thread specifically developed for sewing foundation garments and lingerie such as Resilon, Poelon, Satin, and Berlon (#50, #60) |
| Not-applicable thread | Thread which has naps, decorative yarn of multi-fiber thread such as woolly thread, Berlon D420 and D300, and spun thread |
Please consult us if you want a non-rotational bobbin
