Abstract

A hemming apparatus for a sewing machine includes a hem folding attachment which guides a cloth edge portion into the sewing machine and an aiding apparatus which prefolds the cloth edge portion into an S-shaped hem before it reaches the hem folding attachment. The aiding apparatus includes a rotatably supported free roll, a ring thereon for setting the position of the cloth edge portion, a fitting mechanism engageable with the top of the hem, an under guide plate engageable with the bottom of the hem, and a base guide spaced above the under guide plate. As the edge portion of the cloth extending between the hem folding attachment and free roll and defining the upper fold of the hem is advanced toward the hem folding attachment, an adjacent portion of the cloth is moved by the fitting mechanism gradually further into the region between the base guide and the under guide plate so that the hem assumes the prescribed S-shape.
