TNU-243
SPECIFICATIONS
WHEN YOU PLACE ORDERS
● The machine has a wider free space under the machine arm to
allow the operator to easily place and remove a large sewing
products.
● 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
materials sewn with lower-count threads.
● The lifting range of the presser foot is as high as 20mm for
smooth placement/removal of extra heavy materials.
● TU-273
The top-feed amount is adjustable within the range of ±20%
of the bottom-feed amount.
● TNU-243
Thanks to the TNU-243's unison-feed mechanism, the machine's
higher feed efficiency guarantees the output of high-quality
seams free from uneven material feed.
