Industrial Machine
How Juki Industrial Machines Are Shipped and Packaged
Juki industrial machine heads are packed in a secured box or crate and will be shipped under the assembled table on a skid or pallet. the customer is responsible for installing the machine head into the table, connecting the motor belt/belt guard and assembling the thread tree using the included hardware. The only exception to this would be the LK-1900B which ships completely assembled due to the more difficult set up.
Disclaimer: Due to the weight of the table with motor, there might be some minor marring or scratches due to shipping. This is normal when shipping industrial machines because of the weight associated with the items. Some machines may be subject to additional freight shipping where the machine is shipped via a crate due to the size and weight. Freight Charges Apply: After your purchase, we will contact you with the final freight amount. Please select “Freight Charges” upon check-out starting at $150; the minimum charge.

Juki MO-6814 - High-speed Industrial 4 Thread Overlock Stitch Serger
This advanced overlock machine is easier to use and promises superior cost effectiveness.
The Juki MO-6800S Series responds to various kinds of sewing materials and processes, producing delicate and beautiful soft-to-the-touch seams while further reducing operating noise as well as increasing durability. This advanced overlock machine is easier to use and promises superior cost-effectiveness as well as the responsiveness from light- to heavy-weight materials with a lower applied tension.

The machine achieves beautifully finished seams of improved quality even when run at a high speed.
The machine is widely applicable to the sewing of light- to heavy-weight materials. Since the machine is provided with a needle thread take-up mechanism and a looper thread take-up lever, it ensures high-quality, well-tensed and soft seams with a beautiful texture which flexibly correspond to the elasticity of the materials even when run at speeds as high as 7,000 sti/min. In addition, the machine has a wider and brighter needle entry and provides improved responsiveness to the materials, thereby helping the operator use the machine more easily. The optimally-balanced design of the machine reduces both operating noise and vibration, contributing to more comfortable sewing work.

The machine is provided with functions which contribute to easier operation.
The differential-feed micro-adjustment mechanism, external increasing of the differential feed ratio and the main feed dog height can all be adjustable on the front face of the sewing machine with a screwdriver. The machine is provided as standard with functions which enable easy and best-suited adjustments according to the material to be used.
