ABSTRACT:
A sewing-material feeding device for a sewing machine has an upper material feeder and a lower material feeder which coact for feeding the sewing material, the lower material feeder being adjacent to the throat plate. The needle passes downward through an extension associated with the upper material feeder, the extension defining a downward-facing resting surface, the resting surface obstructing upward movement of said sewing material and thereby reducing fluttering of the sewing material as the needle is pulled upward and out of the sewing material. A tongue adjacent the throat plate is urged upward and against a portion of the upper material feeder so as to further reduce fluttering of the sewing material as the needle is pulled upward and out of the sewing material. The tongue has a throat hole for receiving the needle when it pierces the sewing material and passes into the throat plate.
