Four different feeding methods are available

The TSH-411U can be modified to sew sharp curves by replacing the presser foot with a roller presser. Use: Decorative stitches on shoes, bag handles, etc.
With its bottom feed and feed-dog feed, the machine sews articles entirely free from uneven material feed. Use: Shoes, seat belts, etc
The top feed amount is adjustable within the range of ±30% of the bottom feed. Use: Gloves, tents, bags, bag handles, shirring, tape-attachment with a binder installed on the machine, etc.
A top & bottom feed mechanism has been added to the machine's needle feed system.This ensures a higher feed efficiency and the production of higher-quality seams without uneven material feed. Use: Bags, pouches, shoes, seat belts, etc.
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.
