Abstract: A method of and an apparatus for feeding a cylindrical piece of fabric to a sewing portion of a sewing machine whereby a hem is set at the edge portion of the fabric as a twice-folded, three-layered band. The apparatus has parallel supports for the cylindrical fabric both secured to the sewing portion, and a plurality of pairs of clamp plates disposed to the left and right of the supports at forward and backward positions and movable to the left and right and back and forth. The cylindrical piece of fabric is supported around the supports and four pairs of clamp plates are moved in such a manner that the fabric portions are appropriately stretched and the fabric has a twice folded portion.

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.
