TSH-411 (Bottom feed) - can  be modified to sew sharp curves by replacing the presser foot with a roller presser.

TSN-421 (Needle feed) - With its bottom feed and feed-dog    feed,    the machine  sews  articles entirely free from uneven material feed.

TSU-471 (Top & bottom feed) - The top feed amount is adjustable within the range of ±30% of the bottom feed.

TSC-441 (unison feed) - 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.
