发明名称 Method of and apparatus for feeding fabric to sewing machine
摘要 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. With the left and right portions of the folded portion pressed by the backward pairs of clamp plates, the forward clamp plate pairs are removed from the fabric, and with the folded portion pressed in this way, the fabric is fed to the sewing portion where it is then pressed at a left or right portion thereof by means of another clamp plate. Finally, the backward clamp plate pairs and subsequently the last clamp plate are removed.
