Top & bottom feed
1-needle, Semi-long Flat Bed, Lockstitch Machine with a Large Shuttle-hook for Extra-heavy-weight Materials
Product features
The machine is optimally suited for the sewing of extra-heavy-weight materials
The machine is optimally suited for the sewing of extra-heavy-weight materials such as tents, seat belts, and bag handles.
The top feed amount is adjustable within the range of ±20% of the bottom feed amount.
Thanks to the TNU-243U’s unison-feed mechanism, the machine’s higher feed efficiency guarantees the output of high-quality seams free from uneven material feed.
Higher lift of the presser foot
The lifting range of the presser foot is as high as 20mm for smooth placement/removal of extra-heavy-weight materials.
Frequency of bobbin thread replacement is reduced
The machine comes with a large shuttle-hook. This type of shuttle-hook helps to reduce the frequency of bobbin thread replacement and is best suited for the sewing of extra-heavy-weight materials sewn with lower-count threads.
The bobbin winder is built into the front portion of the machine
The bobbin winder is built into the front portion of the machine arm for easy manipulation.
Basic performance
Wider space under the machine arm
The machine has a wider free space under the machine arm to allow the operator to easily place and remove a large sewing products.
