Abstract
A sewing machine for sewing a fabric comprising, a reciprociting needle, a hemming device comprising a guide member having an edge guide extending towards the needle, and an elongated hemming guide extending laterally from the guide member and including a device for retaining the fabric in a folded configuration passing towards the needle. The sewing machine has a device for sensing passage of a cross-seam of the fabric as it passes along the guide member, a device responsive to the sensing device for shifting the guide member and hemming guide along with the fabric laterally away while the needle penetrates the fabric in the region of the cross-seam, and a device for returning the guide member and hemming guide along with the fabric to its original position.
