ABSTRACT:
An automated sewing device for sewing at least one base material with two curved corner portions, which includes a sewing machine, a base guide plate and a movable guide plate. The movable guide plate has three guide rollers, each being respectively disposed at the apexes of an equilateral triangle, in the reverse side thereof, and the movable guide plate is formed with a plurality of guide grooves in such a pattern that describes three loci respectively of the three guide rollers required to cause proper displacements of the movable guide plate for guiding at least one side of the base material including the two curved corner portions in a direction to the sewing needle of the sewing machine. With such arrangement, the base material is automatically fed and sewn by the feeding and sewing force of the sewing machine, insuring to precisely sew each of the two curved corner portions of base material along the curvature thereof.
