Juki LU-2216N-7 Lockstitch Machine
Long-arm, Unison-feed, Lockstitch Machine with Vertical-axis Large Hook and Automatic Thread Trimmer
Distance from machine arm to needle as long as 650mm.
The machine responds outstanding it to the sewing of large, heavy materials such as car seats and furniture.
Longer distance from machine arm to needle
With the long distance from the machine arm to the center of the needle, a full 650mm, the machine is ideally suited to reinforcement stitching processes for attaching tape and intermediate sewing processes such as topstitching for large work pieces.
Higher productivity
Both the LU-2216N-7 (1-needle) and LU-2266N-7 (2-needle) achieve the maximum sewing speed of 3,000rpm. With this capability, the machine demonstrates higher productivity when sewing long lengths of materials.
The machine adopts a fully automatic lubricating method
With fully automatic lubrication, the cumbersome task of oiling the machine by hand is eliminated.
Oil is forcedly circulated through the face plate by a plunger pump. This prevents oil leakage from the face plate.
The presser foot lift is as high as 16mm
The presser foot goes up as high as 16mm. This ample lift ensures easy setting of heavy materials on the machine and comfortable operation.
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.
The standard machine lets the operator adjust the vertical stroke of the walking foot and presser foot (DL device)
In processes such as the sewing of heavy materials or hard-to-feed multi-layered portions, a press on the DL switch instantly change over the vertical stroke of the walking foot and presser foot.
The result is beautifully produced seams without stitch gathering.
Thread trimming without fail
With the rigidly moving knife shaft and optimal knife movement, the thread trimmer cuts thick thread without error. Moreover, no adjustment is required even when the yarn count is changed.
