Abstract
An arrangement of sewing successive edges of material which extend in two directions. The arrangement comprises a stationary sewing table having a prescribed sewing area. The sewing table supports a carriage. A sewing machine is supported by the carriage. Drives are provided for the carriage and the sewing machine and are operative to move the carriage selectively in the X and Y directions while operating the sewing machine to sew. A material feeding assembly having an independent drive is provided to feed material into the sewing area and to maintain the fed material in the sewing area in a flat fixed position for a prescribed period of time. A control operates to actuate the feeding assembly to position the material, to actuate the sewing machine to sew and to actuate the carriage carrying the sewing machine to move in the X and Y directions about the sewing area forming automatically a folded fabric having all edges stitched.
