The LH-3500A, with a large hook for jeans, is provided with a "large hook" which is 1.7-fold larger than the standard hook provided for the model launched this last January. With the large hook, this machine helps reduce the frequency of bobbin thread changing when sewing jeans or the like with thick thread. In addition, the curvature of the thread path has been minimized to improve the feed locus. This promises a strong and smooth feed of the material even when sewing heavy-weight materials for jeans.
