The MEB-3900 reduces the machine time due to its maximum sewing speed of 2,500 sti/min and its speed-up cloth cutting knife, thereby demonstrating increased productivity.
Then newly adopted direct-driven main shaft by means of a compact AC servomotor not only achieves enhanced responsiveness but also achieves both reduced noise and reduced vibration. In addition, the machine has adopted an air-driven cloth cutting knife that promises excellent responsiveness and operates faster than the conventional knife.
Two different thread trimmers are prepared.
One of them can be selected according to the customer's needs.
The overall thread trimmer has been putting importance on productivity.
It promises thread trimming without fail and trims the thread in a short time.
The operator is no longer required to carry out fine adjustments of the thread trimmer when changing the sewing length.
A sewing machine with a needle thread trimmer (Needle thread trimming type) has been the MEB Series in response to customer needs.
The machine has adopted a direct-drive method that connects a compact AC servomotor directly to the main shaft. The quick startup and increased stopping accuracy obtained as a result guarantees outstanding responsiveness. In addition, the direct-drive motor does not use a V-belt to reduce power consumption.
Needle thread tensions can be digitally established on the operation panel according to sewing conditions. Data can be registered on a pattern-by-pattern basis to easily reproduce the same sewing conditions.
Using conventional machines, it's often quite difficult to reproduce the same sewing conditions. This machine does it with ease. With this capability, the MEB-3900 responds immediately to material changes, significantly reducing the time required for setup changes or adjustments. The machine also ensures the consistent production of high-quality seams.
The machine promises high-quality seams by smoothly responding to changes in stitch formation and allowing the operator to set a separate thread tension for the bartacking sections of buttonholes.
Thread tensions for the beginning and end of sewing can also be separately established. This helps prevent loose stitches or slip-off or raveling of thread at the beginning of sewing.
Since fewer parts need to be threaded, the machine can be threaded more quickly and easily than conventional buttonholing machines.
Management, browsing, and editing of data can be carried out on the application software
Data on sewing machine adjustments made according to the product to be sewn can be transferred to a commercially available Android tablet in contactless mode. This enables quick check for uniform settings as well as confirmation of conditions of sewing machines in a sewing line, thereby facilitating setup changes. The operation panel is also provided as standard with a USB port. Data management and software updates can be carried out with ease using a USB thumb drive.
Data items of sewing can be numerically managed to ensure "stable quality" and "reduction in time required for setup changes".
Quantified sewing data can be externally taken from the sewing machine using an Android tablet or USB thumb drive.
*Android OS Version 6.0 is recommended to use JUKI Smart APP.
(Operation is confirmed with respect to Versions 5.0 and later.)
Contact JUKI distributor in your area for how to use the application software.
The machine is provided as standard with 12 different stitching shape patterns. As many as 87 different patterns can be stored in memory and selected.
The machine head has a wider space under the work clamps to permit easy placement of a sewing product, thereby improving workability.
The semi-sunken machine head promises easy placement and smooth handling of sewing products. Pistol pocket sewing of finished product became easier.
The amount of material opened can be easily adjusted using the screw mounted outside the machine head.
Projection of the arm frame of the machine head has been reduced. In addition, the cloth cutting knife is located closer to the operator side as compared with the conventional model.
Viewability, when placing the material on the sewing machine, is improved, thereby contributing to improved workability. In addition, the thread clamp mechanism of the needle thread clamp (optional) has been improved for better viewability.
When the blade of the cloth cutting knife wears, It can be adjusted by changing the height of the spacer.
A latch-type bottom cover is adopted. Daily maintenance (threading, adjustment of the looper thread, cleaning, etc.) can be carried out without raising the machine head.
The computer-controlled design eliminates most of the complicated mechanisms.
This dramatically improves maintainability.
The machine head is supported by a gas spring that makes it easy to raise for smoother cleaning and threading. The tilted-up machine head can safely take down thanks to the mechanical lock.
An LED light is provided as standard on the underside of the jaw of the machine head.
The area around the needle entry is brightened to improve workability.
The brightness of the LED can be adjusted to 20 levels.
Adoption of a direct-driven main shaft and a revamping of the curve sections of the thread take-up cam and looper cam contribute to remarkably reduced vibration and noise.
The machine automatically reclaims cloth chips after cloth cutting action to keep the working environment cleaner.
Besides any applicable warranties provided by the Original Manufacturer, Jacksew offers a standalone 90-day limited warranty on defects in materials and workmanship.
This warranty covers all the machine parts and labor but any shipping costs must be covered by the customer
Only applies under normal sewing conditions as prescribed for the machine
Consumable items are not covered (needles, bobbins, bobbin cases, springs, oil, and belts)
This warranty does not cover improper use or abuse under heavy use of machines
This warranty does not cover flood, fire, or other acts of nature
If there are any warranty issues that arise, we ask that you contact us immediately and let us know the details. In most cases, we can guide you with getting your machine in good sewing condition via phone, text or video chat.
If you need any parts that need to be replaced, we stock the majority of parts for immediate shipment. Some parts not in stock may have to be ordered from the manufacturer and may take 1 to 2 weeks for arrival.
If there is a critical issue that needs to be addressed and is out of scope of minor adjustments or repairs, we will ask you to send us the machine to our shop so we can have it repaired and have it back to good sewing condition. In most cases, we will only need the machine head shipped to us. Shipping charges - both inbound and outbound - are the responsibility of the customer.
Warranty issues do not arise frequently because of our commitment to assemble, test and verify each machine we ship out to our customers. We will never send you a machine directly from the manufacturer in boxes without knowing that the machine will be ready to operate upon arrival.
DISCLAIMER: DUE TO THE HEAVY WEIGHT AND SHIPPING METHODS USED FOR INDUSTRIAL MACHINES THEY MAY EXPERIENCE MARRING AND SCRATCHES DURING SHIPPING. THIS WILL NOT AFFECT THE OPERATION OF THE MACHINE.
ANY DAMAGE OCCURRING DURING SHIPPING MUST BE CLAIMED TO THE FREIGHT CARRIER IMMEDIATELY. UPON REQUEST, JACKSEW WILL PROVIDE ASSISTANCE IN FILING A CLAIM ON YOUR BEHALF DURING SUCH AN EVENT. PLEASE NOTIFY US WITHIN 5 BUSINESS DAYS.
