ABSTRACT:
An apparatus is provided for processing peripheral selvedges of fabric. The apparatus includes a sewing machine unit for sewing up fabrics; an air table mechanism incorporating a number of jet apertures through which air is jetted onto an upper surface of the table in an obliquely upward direction towards a product guide member; a supplementary roller unit which vertically ascends and descends to shift a processable fabric synchronously with feeding of the sewing machine unit; a rotating unit having a fabric holding unit which descends only when sewing of a fabric corner is executed in order to hold and rotate the objective fabric by a predetermined angle and then ascends after rotating the fabric by a predetermined angle; a flange strip supply unit for supplying a flange strip to the sewing machine unit; and a controller unit for integrally controlling operation of the above component units. The flange strip supply unit includes a feed roller driven by a motor, a rotatable pressing roller, a cutter unit, and a pressing unit for pressing both sides of the flange strip fed from the flange supply unit by centering the flange strip around a travelling line of the cutter.
