Abstract

A method and apparatus for feeding a tubular fabric to a sewing portion of a sewing machine so as to set a hem on the edge portion of the fabric formed as a twice-folded, three-layered band. The operation is performed so that a left rear clamp is moved to the right so as to contact a holder extending from the sewing portion on its left side; the tubular fabric is inserted around the holder from the free end thereof; a main left front clamp is moved to the right and a right front clamp is moved to the left so as to clamp intermediate portions of the peripheral surface of said fabric from the outside. Then the left rear clamp is moved to the left and a main right rear clamp is moved to the right so as to stretch right and left sides of the fabric closer to the sewing portion from the inside to the outside, so that the right and left sides of the fabric become wider than the clamped portions of the fabric. Then the left rear clamp and main right rear clamp, while stretching the fabric, are moved toward the clamped portions of the fabric along the holder, so that the edge portion of the fabric forms a twice-folded, three-layered band.
