DNU1541 Industrial Lockstitch Machine

$

1-needle, Unison-feed, Lockstitch Machine with Double-capacity Hook

With its reliable feed and consistent seam quality, JUKI’s DNU-1541 Series responds outstandingly to the sewing of heavy materials.The JUKI DNU-1541 is a heavy-duty, single-needle lockstitch machine designed for professional sewing of thick and multi-layered materials. Featuring a unison-feed mechanism and a double-capacity hook, it delivers consistent stitching and smooth feed performance—even on challenging fabrics. With a maximum speed of 2,500 stitches per minute, easy stitch length adjustments, and an adjustable walking foot system, it balances power, speed, and precision. Enhanced visibility, user-friendly controls, and a centralized lubrication system make it ideal for high-volume production environments like upholstery, leatherwork, and industrial sewing.

What’s Included

Special Features

The DNU-1541 Series has excellent sewing capabilities and feed performance

The alternating vertical movements of the walking foot and presser foot are as large as 6.5 mm.

In addition, the ratio between alternating vertical movements of the walking foot and presser foot remains unchanged even when the material thickness changes. Thanks to this feature and the adoption of a new method of rectangular feed that prevents the needle from fraying, the DNU-1541 machine sews multi-layered parts of a material with consistent stitching pitch while preventing stitch gathering.

High-speed performance increases productivity

The DNU-1541 delivers increased productivity at sewing speeds as high as 2,500sti/min (DNU-1541, -1541S) or 3,000sti/min (DNU-1541-7).

The vertical stroke of the walking foot and presser foot can be easily set and changed

The vertical stroke of the presser foot and walking foot (amount of alternating vertical movement) can be easily changed with the large dial mounted on the top of the machine head. The sewing speed is automatically regulated based on the vertical stroke setting. This ensures ideal sewing conditions at all times.

A helpful automatic reverse feed function is provided as standard

With just a light press on the one-touch type reverse feed button, reverse feed stitching is actuated. Furthermore, if a suspended ruler is attached to the machine or a 3-dimensional sewing product is sewn, the button can be shifted upward to prevent interruption.

Excellent operability and maintainability

The stitch length can be easily selected by the stitch dial.

The machine’s enhanced operability features include a clear view of the area around the needle, placement of the bobbin thread winder on the front face of the machine arm, and a large handwheel (φ160mm).

A knee-lifter mechanism is built in the bed. This reduces the pressure required to operate the knee-lifter and facilitates setup.

The machine’s full-open-type top cover design makes adjusting works easier.

The machine comes with a lubricating mechanism that uses a centralized oil wick. This substantially reduces the time and trouble required for oiling the machine. (Hook: automatic.)

A walking foot mechanism is built into the DNU-1541 arm to prevent oil from scattering.

The area around the needle entry is designed to be easily observed

Since the needle thread tension-release solenoid is fitted on the rear face of the machine head, the area around the needle entry and one-touch type reverse feed button is easily viewable. This substantially contributes to improved operability.
