ABSTRACT:
A sewing machine for simultaneously performing hem stitch and blind stitch. The sewing machine comprises a first looper placed above one end of a hem of cloth to be stitched and along the hem reciprocated to cross with a blind needle which is passed through the cloth; and a second looper placed above the hem to be stitched and adapted to move along a loop-like track which resembles the outline of a saddle and syncronizes generally with the reciprocation of said first looper.
