1-needle, Unison-feed, Lockstitch Machine with Double-capacity Hook
JUKI DNU-1541-7 (with automatic thread trimmer)
JUKI DNU-1541S (with safety mechanism)

With its reliable feed and consistent seam quality, JUKI's DNU-1541 Series responds outstandingly to the sewing of heavy materials.

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 6.5mm.

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 needle from fraying, the DNU-1541 machine sew 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).

Safety mechanism (DNU-1541S)

When the thread is caught in the hook or any other sewing trouble occurs, the safety mechanism will automatically operate to prevent the DNU-1541 machine from being damaged.

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.

Thread trimming without fail (DNU-1541-7)

Consisting only of a moving knife and counter knife, the simple and well-balanced thread trimming mechanism is capable of cutting thick thread up to without fail.

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 easilyobserved

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.
