ABSTRACT:
According to the invention, when a fabric feed device is set to sew a fabric with the straight stitches of smaller feeding amounts (or pitches), a machine operator is not required at first as conventionally to deliberately push the front edge of the fabric forwardly deep between a feed dog and a fabric pressor. The device of the invention is designed to effectively transport and sew the front edge of the fabric at an initial stage of straight stitching of smaller feeding amount. Further according to the invention, an adjustment of smaller feed amount may be effectively carried out in case of button hole stitches and satin stitches.
