Abstract
An automated sewing device for automatically sewing together rectilinear and curved end portions respectively of two base materials. A guide element is provided to separate the two base materials from each other and guide them in a sewing direction, and a guide roller mechanism is provided, which operates to adjustingly bring one guide roller to contact with the base material having the curved end portion and rotate the guide roller to move that base material in a direction orthogonal with the sewing direction, thereby keeping the rectilinear and curved end portions in alignment with each other. Hence, a seam is created along the curved end portion with a constant margin given between the seam and the curved contour of the curved end portion. A pair of guide rollers may be provided to move two curved end portions in a direction orthogonal with the sewing direction for the same alignment purpose.
