TU-273U (Top & bottom feed)
The top feed amount is adjustable within the range of ±20% of the bottom feed amount.
TNU-243U (Unison feed)
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.
