Abstract
A method and machine for simultaneously forming seams along opposite sides of a garment workpiece in which the edges being sewn are gradually aligned so as to follow rectilinear paths that coincide with the machine's lines of sewing. The excess material of the garment disposed between the opposite sides being sewn is gathered and caused to pass through the area intermediate the lines of sewing. The sewing machine adapted to perform this function is provided with a pair of spaced needle bars that define the machine's lines of sewing and the space between these lines is clear of any interfering elements thus providing an area for the material intermediate the opposite sides to pass which has a width greater than the distance between the lines of sewing.
